I have a dependency on Xamarin.Android.Support.v4 - which provides functionality described below:
Hello,
For using those APIs you mentioned, you could refer to the following documentations:
AndroidX.Core.View
OnApplyWindowInsetsListener
[ViewCompat.SetOnApplyWindowInsetsListener](
https://developer.android.google.cn/reference/androidx/core/view/ViewCompat#setOnApplyWindowInsetsListener(android.view.View,androidx.core.view.OnApplyWindowInsetsListener\)
)
AndroidX.Core.Content:
[ContextCompat.CheckSelfPermission](
https://developer.android.google.cn/reference/kotlin/androidx/core/content/ContextCompat#checkSelfPermission(android.content.Context,java.lang.String\)
)
[FileProvider.GetUriForFile](
https://developer.android.google.cn/reference/androidx/core/content/FileProvider#getUriForFile(android.content.Context,java.lang.String,java.io.File\)
)
And here are the samples of using the APIs in Xamarin.Forms on Android platform:
Implement IOnApplyWindowInsetsListener:
public class RootViewDeferringInsetsCallback : WindowInsetsAnimationCompat.Callback, IOnApplyWindowInsetsListener
public RootViewDeferringInsetsCallback(int dispatchMode) : base(dispatchMode)
public WindowInsetsCompat OnApplyWindowInsets(View v, WindowInsetsCompat insets)
public override WindowInsetsCompat OnProgress(WindowInsetsCompat insets, IList<WindowInsetsAnimationCompat> runningAnimations)
ViewCompat.SetOnApplyWindowInsetsListener:
RootViewDeferringInsetsCallback callback = new RootViewDeferringInsetsCallback(WindowInsetsAnimationCompat.Callback.DispatchModeStop);
ViewCompat.SetOnApplyWindowInsetsListener(your_view, callback);
ContextCompat.CheckSelfPermission:
var selfPermission = ContextCompat.CheckSelfPermission(this, Manifest.Permission.Camera);
if (selfPermission == Permission.Granted)
FileProvider.GetUriForFile:
At first, please refer to FileProvider to configure your FileProvider.
Then, in you Xamarin project, you could use the following code to call FileProvider.GetUriForFile:
File imagePath = new File(FilesDir, "my_images");
File newFile = new File(imagePath, "default_image.jpg");
Android.Net.Uri contentUri = FileProvider.GetUriForFile(this, "com.mydomain.fileprovider", newFile);
