How To Get Listpreference Value In Kotlin Activity

At this point, we've either added all of our settings gadgets programmatically, or have configured our preferences display using an xml resource file. So now that we've our settings fragment, we have to truly show it to the person. For this, we're going to create an activity to deal with our fragment and set our fragment container to show our settings fragment occasion. Also introduce the datastore-manager which includes apis to simply entry those settings on non compose screens. Shared Preferences are appropriate in different conditions. For instance, when the user's settings have to be saved or to retailer data that can be used in different actions inside the app. The data saved utilizing shared preferences are kept non-public throughout the scope of the application. However, shared preferences are completely different from that activity's instance state. When it involves reading preferences values, we can make use of the PreferenceManagerclass to retrieve the default shared preferences for our application. From here we will access the preferences value by making use of the necessary thing that we assigned it during the definition of our settings. MethodDescriptionsetActivityTitleSets the toolbar title for the SettingsActivity. The default value is 'Settings', translated to all supported languagessetActivityTitleSets the toolbar title for the SettingsActivity with a string resource. Default is trueshowResetOptionEnables or disables an choices menu item for resetting all preferences to the default values. Default is falsesetPreferenceCallbackSets a callback for subscribing to click on events of preference itemsIf you miss a customization option, please tell us, by opening a difficulty. On implementing SharedPreferences.OnSharedPreferenceChangeListener we're prompted to implement the method onSharedPreferenceChanged. This method is called each time there is a change within the SharedPreferences file. (This is the file the place all our preferences are saved in key-value pairs). You can use sharedpreferences and key values to make specific adjustments within the app.

"title" is used to level out the title of setting, "entries" is used to indicate the list of entry to the consumer and "entryValue" is the value corresponding to each entry. SharedPreference needed to set value in Language in settings so that after user close app and again open it setting will present identical value in any other case it will show default value. We used an array of string to show the list of languages. In this fragment, you could also want to configure your settings programmatically as an alternative of via an xml file. In the previous sections we outlined how you can create settings gadgets programmatically, so let's take a quick have a glance at how we can apply these within our settings fragment. We start by making use of the PreferenceManager reference to create an instance of a Preference Screen. When creating through xml all of this configuration is handled for us, within the case of programmatic preference configuration we're required to set this stuff up ourselves. Sometimes, relying on the applying, it could make extra sense to just finish the PreferenceActivity as an alternative of restarting it. Android offers some ways of storing data of an utility. Shared Preferences permit you to save and retrieve data within the type of key,value pair. In order to use shared preferences, you must call a way getSharedPreferences () that returns a SharedPreference instance pointing to the file that ... One of essentially the most Interesting Data Storage choices Android supplies its customers is Shared Preferences. Shared Preferences may be thought of as a dictionary or a key/value pair. For example, you might need a key being "username" and for the worth, you would possibly store the user's username. You can have a simple shared preference API that you can use to retailer preferences and pull them back as and when needed. Shared Preferences class supplies APIs for reading, writing, and managing this data. This settings display screen will look much like what we are ready to get to see in YouTube settings in the General possibility. In this article we are going to learn how to implement the settings display contemplating the assorted combos of settings items.

Within this class you'll notice we override an onCreatePreferences methodology — this is what is used to configure our preferences display. Within this, we make use of the setPreferencesFromResource method to assign an xml file which might be used to configure our preferences. Here, our outlined xml file will be taken and its contents might be used to construct the preferences which are displayed on-screen to the user. For that purpose there's a if statement checking for a positive button press . That being the case, the present Editor from the current SharedPrefence is obtained and stored at a variable named preferencesEditor . With that, all of the preferences can be edited, so all their saved values are being deleted and all of the default values are being loaded again and stored at their respective preferences . To do this, we begin off by defining a model new subclass of PreferenceFragment. To do that, we override the onCreate () technique of the fragment and ... I used to retailer the selected language as a string in format lang-REGION within the shared preferences beneath the name general_language. It was a really old decision from the time I knew nothing about languages and translating cellular apps, and over time, there was no motivation to change it. It simply labored, and altering the working code without cause is normally not the most effective concept, you understand . I have carried out three spinners and one save button. User selects the spinner value, and after pressing the save button, the values might be saved in shared preferences. I don't know how to get the value from the spinner and display it after opening the appliance. When you open the resource file, there's a structure referred to as root preferences, where all of the settings might be represented. Several preference categories will maintain a particular group of settings. Note that we get the values from the default SharedPreferences for our utility.

We have a variable sBindPreferenceSummaryToValueListenerthat is an occasion ofPreference.OnPreferenceChangeListener. This is solely a preference change listener that may assist us replace the preference abstract to the value the user has chosen. We check for particular cases, like when the selected preference is a RingtonePreference or a ListPreference. For those preference types, we do some special dealing with to get the summary string. If the preference is neither , we simply set the summary to the preference's string value. These are often fundamental to settings screens, allowing your customers to toggle and choose the different settings options offered by your software. If we're going to create our preferences via an XML useful resource then we have to begin by defining a model new PreferenceScreen useful resource within the res/xml listing of our app. Within this we will then outline the totally different preferences that we want to show on this screen. Luckily, Android Jetpack homes what is called the Preference Library. This provides us with a approach to create our software preferences with minimal work from the builders side. In Android apps, there are sometimes settings pages that comprise different choices the consumer can tweak. The PreferenceFragment and PreferenceFragmentCompat accommodates a hierarchy of preference objects displayed on display in an inventory. These preferences will mechanically save to SharedPreferences as the consumer interacts with them.

Layout file for SettingsActivity is shown below (activity_settings.xml). It connects this activity to any of the courses present in your whole project which are inheriting from PreferenceFragmentCompat class. You might need a couple of class inheriting from PreferenceFragmentCompat class when you app has multiple settings display. Before super.onCreate and setContentView is recognized as, we read our theme from the preferences and apply using setTheme method. When we modify our theme from settings, the principle activity should get notified of the change so that it might possibly restart itself and which in flip will re-apply the model new theme. This is essential so that the brand new theme will get utilized dynamically. This is the code you should set the summary to the chosen value. It also sets the values on startup and respects the default values, not only on change. Just change "R.format.prefs" to your xml-file and extend the setSummary-method to your needs. It truly is simply handling ListPreferences, but it's easy to customise to respect other Preferences.

In the code above, we created a nested class SettingsFragment inside SettingsActivity . Note that our class SettingsFragment extends the PreferenceFragment superclass and has a way addPrerenceFromResource inside onCreate(). In this method, we gave it a useful resource ID R.xml.preference of the preference XML to launch—when the Fragment is loaded. Finally, we host the Fragment to the activity by merely using theFragmentTransactionto add it to the UI—inside onCreate() of SettingsActivity. In many apps, we have seen the Settings screen which is most typical in a lot of the apps. This settings display is used to handle the preferences of the customers. For creating this settings screen android offers a function to make a settings preferences display screen. In this article, we'll take a look at implementing the preferences setting screen in Android. The preferences display screen could be designed with an xml just like the structure xml we use for a view, besides it's going to reside in xml directory. We have used under elements within the present settings display. In order to display our preferences on the display to our user, we're going to need to create a new occasion of the PreferenceFragmentCompat class. If we're going to create our preferences from an xml file then this is going to be a pretty barebones class. Settings screens present a means for our customers to configure our software for the way during which they need it to look, really feel and behave. As properly as this, it's also a fantastic place for us to supply hyperlinks to exterior data corresponding to privacy policies, open-source licences and more. Whilst we are ready to construct these screens ourselves, there can typically be plenty of boilerplate for what looks like such a easy requirement. Not only do we have to create the person interface, we additionally have to create the logic used to learn and write the values from our utility preferences file. Now whenever you press save button, the text shall be saved in the shared preferences. Now open it once more and you will note all the text you could have written back in your utility.

I added an option for selecting the completely different language in settings. When the user clicks on Language option a dialog box pops up. I used listpreference to indicate the list of various languages. As I said within the start of the tutorial that PreferenceFragment can be used to host the PreferenceScreen as the PreferenceActivity. Preference Headers sre used to organise the Preference Screens in subscreens. So we are creating another activity SettingsActivity2. We will implement preference_header and PreferenceFragment in this activity. three for 3 Preference Screens and 1 for Preference Header. So as I told, I'm utilizing settingsTextView to show the SharedPreferences knowledge. For simplicity I'm assuming of an application which has background sync. I'm assuming that the applying would permit consumer to enable or disable the background sync, and in addition customers can specify the sync interval. This application additionally shops user's name and e-mail, and likewise allows to switch them. It also has an choice to customize push notification ringtone. During the event of cellular applications, a common requirement is of storing app associated data to the phone. In Android we carry out this task with the assistance of Preference APIs. We can also need settings that enable customers to change preferences in app. ThankfullyAndroid offers a powerful framework to handle person preferences. To build the settings display in its default configuration, you'll be able to merely name the show method of SimpleSettings and cross the ready xml resource file to it. The following figure illustrates this performance with the sunshine themes preferences set. In this class, we created a helper methodology calledbindPreferenceSummaryToValue(), which is inside ourcompanion object, to update the preference abstract textual content with the value the user has chosen.

ThefindPreference() will return a Preference using the Preference's key. This sort of Preference will show a listing of entries in a dialog when tapped. Here, you presumably can specify a pair of string-array resources in your preference XML. This string-array useful resource simply incorporates a group of strings. This resource is located at res/values/arrays.xml. The launched MainActivity makes use of the FragmentManager to load the PreferenceFragmentCompat into the activities root view. The fragment implementation itself merely populates the preferences when created. Note that the preferences framework takes care of loading the current values out of the app preferences and writing them when changed. Earlier on we used the SharedPreference to retailer knowledge using key-value pairs. Android supports PreferfenceActivity and PreferenceFragmentCompat to edit and retailer preferences. It is straightforward to create a hierarchy of preferences through XML. The example we talk about beneath does 90% of the work in XML and little or no code. When the consumer interacts with the fragment there isn't a code needed to create dialogs or new screens to deal with enter from the user or storage. This is an easy and powerful way to deal with system preferences. The downside with creating settings from a template is, there isn't a assure that the auto generated code always meets your requirements. With current model of Android Studio I have (v2.3), the settings activity is generated with all headers as default display which is not essential in my app. Even it takes more effort to customize the auto generated code.

The best method is, create every little thing manually in order that you will have extra management over the output you are expecting. We usually see Settings display in lots of android apps via which you can configure the app preferences on your alternative. For instance you wanna change the notification sound or flip off notification messages from the app settings. At this level, all of our preference items become expanded and visible to the person. In order to use shared preferences, you want to name a way getSharedPreferences() that returns a SharedPreference instance pointing to the file that incorporates the values of preferences. Call "setter" strategies on the builder in order to specify the title, message, etc. for the dialog that can seem. This can be hard-coded textual content or a reference to an XML String useful resource (as a user-facing String, the later is extra appropriate for revealed applications). Each setter method will return a reference to the builder, making it easy to chain them. Such options should be carried out within the cloud aspect and not by storing them in local app knowledge. Any consumer can clear shared preferences and manipulate the info. We need an editor to edit and save the changes in shared preferences. The following code can be used to get the shared preferences. On clicking Language option a dialog field pop up with the list of different languages. When the consumer chooses a language then we save corresponding language code in preference with key "prefLanguage" in order that we will use it later to send it to the server along with the question. It additionally makes use of to send language to the server to retailer person language on the server, so that person can use the identical language in the different consumer. By toggling the theme between the two options given within the preferences, we change the display theme of the entire app. For instance, the next two pictures show the opening display screen displayed with the Custom Dark and Custom Light selections, respectively. You ought to just set up a brand new folder name it xml and the create preference.xml and reserve it there. Preference Headers displays only the settings teams on the first screen and deciding on a group displays the sublist.

The preference headers often used for tablets or if there are multiple settings with nested options. The good thing about utilizing headers is, the display might be mechanically divided into two panels when the app is working on tablet. For the PreferenceCategory we only have to outline a title, which will be displayed a the top of our categorised settings. Once we've outlined this PreferenceCategory within our preferences XML file we just have to play the corresponding Preference items within it. In order to construct a preferences display screen, we've what is called the Preference hierarchy. This hierarchy is used to outlined the completely different preferences properties that could be may be set for our software. There are two ways which we are in a position to outline this hierarchy, programmatically or within XML. The way during which we load our settings into the corresponding element will depend on how we initially define our hierarchy. Now we now have an activity with the preference display screen. If SettingsActivity is the principle activity will most likely be loaded on starting the app, but normally, settings display screen isn't the main screen of the app. So we want to create a method for us to navigate to SettingsActivity. I will have all my preferences settings on this activity. So we need to place the fragment we created on this activity. Use PreferenceFragmentCompat to programatically deal with preferences. To load the settings into the fragment, load the preferences in the onCreatePreferences() methodology. To get an instance of a preference, seek for a preference using its key through the PreferenceManager inside onCreateView(). You can use this occasion to customise the preference, corresponding to add a customized OnPreferenceChangeListener.

Windows 10 Compatibility Checker Online

In addition to increased reliability, the supported processors increase security capabilities at the chip level. These processors provide virtualization extensions and virtualization performance improvements. Windows 11 supports virtualization-based security which enables several security capabilities, including memory integrity, also known as hypervisor-protected code integrity . HVCI disables dynamic code injection into the Windows kernel.

HVCI also provides driver control and ensures that all drivers loaded meet a policy of allowed drivers set by Microsoft and the user. The United States Department of Defense requires virtualization-based security on Windows 10 for their devices. In partnership with our OEM and silicon partners, we will be enabling VBS and HVCI on most new PCs over this next year. And we will continue to seek opportunities to expand VBS across more systems over time. If your existing Windows 10 PC is running Windows 10 20H1 or later and meets the minimum hardware specificationsit will be able to upgrade to Windows 11.

The upgrade rollout plan is still being finalized, but for most devices already in use today, we expect it to be ready sometime in early 2022. Not all Windows 10 PCs that are eligible to upgrade will be offered to upgrade at the same time. To see if your PC is eligible to upgrade, refer to our knowledge base for a list of tested systems. Once the upgrade rollout has started, you can check if it is ready for your device by going to Settings/Windows Updates. More information on how that is presented will be available at a later date.

Additional desktop notification options may be also be added at a later date. Windows 11 continues our strong commitment to compatibility. This means that devices can upgrade to Windows 11 and critical apps and devices will simply work. Raising the Windows 11 minimum system requirements enables us to better support apps and hardware for drivers and devices. Feedback also shows us that unsupported hardware is more likely to have older drivers that are incompatible with new OS features such as VBS.

Supported hardware also comes with modern drivers, which helps ensure not only the reliability we mentioned earlier, but also great hardware compatibility. Determine if your computer adheres to Windows 10 System Requirements. Your processor must be a minimum of one GHz or faster and support SSE2, NX and PAE. If your computer does not support these, an installation of Windows 10 will not be possible. Additionally, make sure your device drivers are all updated. Talk to a hardware technician to determine if you should upgrade components.

Don't forget to perform a manual run of the Windows 10 Compatibility Appraiser if you make any alterations to your system. After you complete the steps, repeat the instructions to back up the files on the remaining accounts . If you usually do not sync passwords and bookmarks with an online service, this is a good time to export your browser credentials and links.

For example, even though Windows 11 is available as a free optional update for Windows 10, the device must meet the new system requirements. Otherwise, you won't be able to proceed with the setup. You need to ensure that the Trusted Platform Module and Secure Boot are enabled on the computer. You also need to make sure the device has enough space and there are no problems before continuing with the upgrade.

Furthermore, you want to create a backup in the case you need to roll back, check the activation status, and create installation media. The program returns one of three possible windows after the compatibility check runs. I'm running Enterprise on my production PC and have flagged this as an error or problem with Microsoft via its Feedback Hub. There are so many touch keys on the keyboard for wifi, sound etc which some times works and some time don't work. Once you complete the steps, the tool will download the files and create an installation media, which you can then use to upgrade a compatible computer to Windows 11.

If you have had the same installation for a long time, you might need to analyze and repair the current setup to fix missing or damaged files. Otherwise, during the upgrade process, the chances of running into issues will be high. However, if you plan to proceed with a clean installation using a bootable USB flash drive, then you can't skip this suggestion since the previous installation will be erased during the process. We will start by creating a package for Windows 10 compatibility check. The source of this package must be the Windows 10 installation media. The deployment option and command line is important here.

If they are not set correctly you'll end up sending the complete installation media (including Install.wim) to the computers only for a compatibility check which is not really effective. Using our proposed methods, you'll be using about 250mb on the client drive instead of 5gb. Following the results of our testing, we are making a small number of additions to the compatible processor list , but otherwise will maintain the minimum system requirements as originally set. This version of the operating system allows software to use 64-bit addresses to access hardware and can therefore access much larger memory spaces. In order to run successfully on Windows bit, all drivers must have native 64-bit support. However, most 32-bit software applications can run within a Windows bit emulation layer.

Very rarely, changing the compatibility mode isn't enough to run an older program. This is because the feature isn't a perfect recreation of older operating systems, and some things like the drivers can still be different. When this happens, try looking at the system requirements of the software in question and install any missing components before trying again.

The Windows setup has an "appraiser" service that checks to see if your computer meets the minimum hardware requirements for that version. It's possible to replace the file in the Windows 11 setup with one from an older build of Windows 10. Disable it by searching for Power Options in the Start Menu and running the matching Control Panel applet, then in the left-hand pane click Choose what the power buttons do. Click Change settings that are currently unavailable, scroll down and un-tick Turn on fast start-up, then click Save changes. This should prevent a very slow start on affected PCs. Some users report that if they subsequently reboot, re-trace their steps and re-enable fast start-up the problem remains cured.

After you complete the steps, the device should be able to boot from a USB installation media and pass the minimum system requirements check. You can refer to our knowledge base for a list of tested systems to determine if your device eligible to upgrade to Windows -11. Many PCs that are less than four years old will be able to upgrade to Windows 11. They must be running 20H1 or later version of Windows 10 and meet the minimum hardware requirements to receive the Windows 11 upgrade. For those who are using a PC that won't upgrade, and who aren't ready to transition to a new device, Windows 10 is the right choice. We will support Windows 10 through October 14, 2025 and we recently announced that the next feature update to Windows 10 is coming later this year.

Whatever you decide, we are committed to supporting you and offering choice in your computing journey. If you want to see the full Windows 11 minimum system requirements, you can visit this page. Your device is officially supported for Windows 11 if it comes with newer processors, TPM 2.0 and Secure Boot. The new Windows 11 is here and it surely comes with a host of interesting features. The latest operating system from Microsoft brings you new visual changes, compatibility with Android, interesting gaming-related features, and more.

The company has also revealed that a vast majority of PC or laptop available in the market will be compatible with Windows 11. The brand has also released a list of minimum requirements and processors that support the latest operating system. That being said, if you want to know whether your Windows 10-powered laptop or PC is compatible with Windows 11, there is a simple way to do it.

In this article, we are going to show a step-by-step guide of how you can check for Windows 11 compatibility with your laptop or PC. My PC says I am good to go, what I would really like to know though is as I am running Windows 7 SP1 and my scanner and Printer work fine in Windows 7. If I update to windows 10 will I be required to install new drivers for windows 10 Operating system, as a number of manufacturers will not be producing legacy device drivers. So the cost of updating to windows 10 although the OS is free may cost me in terms of having to purchase new hardware that is windows 10 compatible. Sorry I have been unable to find a definitive answer from the product website.

Finally, on 14th January 2020, Microsoft end support for its most popular OS Windows 7 and suggest to upgrade the latest windows 10. And now almost every new laptop or desktop comes with windows 10 preinstalled. Most users choose to upgrade to the new system from Windows Vista/XP/7/8. One of the reasons is that your machine is not compatible with Windows 10.

The software, apps, and drivers on your device don't work for the system. In particular, a bad driver can wreak havoc your system. When planning for a Windows 10 migration, understanding your environment is the key. Luckily, Windows 10 setup comes with command line options which one of them is an excellent compatibility check (/Compat ScanOnly). This command can be used on a Windows 7,8 or 10 devices before a migration in order to see if those devices are Windows 10 compatible.

Using SCCM, we will run this Windows 10 compatibility check, return the results in the SCCM database and use this data to build a comprehensive report. This report can be used to detect and fix migration errors before the actual Windows 10 deployment. After the download, double-click the ISO file and then double-click the setup.exe file. Click Next at the initial install screen to check for and download any updates to Windows 11.

At the Ready to Install screen, you will see that Windows 11 will be installed and personal files and apps will be kept by default. In addition to system requirements, you should also check software compatibility and driver compatibility. If you don't do the checks, once you start the upgrade, the Windows 10 installation process will be stopped when some errors and compatibility issues are found. In case you are unable to tell if your computer meets the minimum system requirements to run Windows 11, there's a solution. Microsoft has released a nifty little tool called PC Health Check to check it for you and tell if the computer supports Windows 11.

Below are the steps to use the PC Health Check Tool and find out if you are eligible to receive the Windows 11 update. While you're here, all Windows 10 users might want to click Choose how updates are delivered and ensure that Updates from more than one place is either off or set to PCs on my local network. Windows will do some more calculations and give you another a remarkably similar looking box, this time with the option to delete previous windows installation. You might have to scroll down to find it, but it should be taking up a sizeable bit of drive space, in our case, 5GB. In the separate message box that appears asking if you're certain you want to send this, click Delete Files, and you're done.

Also, make sure you've opted to keep the personal files and apps and click Install to keep your data, apps, and most of your settings untouched. Now, when you hit install, it should start installing the most up-to-date version of the operating system. Once you complete the steps, the package will download, and you can then use it to upgrade any computer that meets the minimum requirements. However, you will need an internet connection to proceed with the upgrade. Furthermore, if you plan to upgrade with a clean installation, you will also need to make sure the computer can start from a USB flash drive.

Emulators and simulators, including Edge simulators and emulators, are a watered-down version of the browser in question and do not replicate all features of the said browser. Once installation has completed, your system will restart and boot into the Windows 10 desktop. Installation of the Windows 10 operating system is now complete, but you still need to install updated drivers, applications and utilities for Windows 10. Similar to Windows XP 32-bit, Windows bit provides access only to 32-bit addresses. As a result, even though Windows bit will run on x64 hardware, it is limited to using 4 gigabytes of RAM. Windows bit cannot run 64-bit versions of drivers or software designed to run natively on 64-bit operating systems.

Both Windows 10 and 11 provide you with the option to set a compatibility mode for each individual program. This way, you can run applications that were meant for older versions of Windows, simply by selecting the correct mode from a list. Like any other software, the Windows operating system keeps getting updated to new versions.

And while the transitions maintain program compatibility during direct upgrades, things start getting murkier across multiple versions. Click Next to have Windows 11 check for any updates, then accept the license terms. The Ready to install screen shows that Windows 11 will be installed and that your personal files and apps will be kept. You can then elect to keep personal files and apps, personal files only, or nothing. After the installation completes, you will be prompted to restart your PC.

You are given the option to restart the machine immediately or wait for the 30-minute timer to end if you need time to save any open work. After your PC reboots, you can sign into Windows again. Once the final setup is complete, you are deposited at your new Windows 11 desktop.

Still, if the app shows that your laptop or PC is not compatible, we suggest you should wait. Because Microsoft has revealed that it will update its hardware compatibility list pretty soon. The company has said the list of hardware compatible devices is constantly being updated in the app. Furthermore, the Windows 11 update will only arrive at the end of the year, this may change until then. Simply put, the Redmond giant might make some changes in the hardware list closer to the official rollout of Windows 11. In most cases, you will be able to fix all incompatibility problems by installing an earlier version of Windows that has the current standing for an upgrade.

Windows 7 and Windows 8.1 will usually work for you. In the case that you have a CPU that is too old for either of these operating systems, you will likely not meet Windows 10 requirements either. In this case, you may have to upgrade your computer hardware. Microsoft has begun the process of rolling out hundreds of millions of free Windows 10 upgrades.

The requirements verification for Windows 11 is currently only built into the initial setup and a post-install program known as the Out of Box Experience . The OOBE usually only runs on clean installs, so if you're upgrading, you only need to worry about bypassing the initial verification. That initial bypass is actually pretty simple — use the Windows 10 installer to install the Windows 11 files. We're not a fan of some of the data-sharing defaults in Windows 10, and we'd recommend all users review them periodically. Use the Start Menu to search for and run the Settings app, then click Privacy.

In the left-hand pane, you'll see many areas where your computer might be sharing data. Note, too, that the default Feedback & diagnostics setting is to send enhanced data to Microsoft. Internet connection Microsoft account and internet connectivity required for setup?
