How to adjust dialog layout when soft keyboard appears using the latest WindowInset API

Question

Question:

How to use the latest WindowInset API to adjust space betweeen my dialog and softkeyboard?

---

I have a BottomSheetDialog with some EditText. The default animation will show the soft keyboard right below my EditText which will cover my save button. After doing some research, I added this line into my BottomSheetDialog fragment

getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

And it worked (as the picture is shown down below)!

This is what I wanted

But apparently SOFT_INPUT_ADJUST_RESIZE is deprecated.

   * @deprecated Call {@link Window#setDecorFitsSystemWindows(boolean)} with {@code false} and
   * install an {@link OnApplyWindowInsetsListener} on your root content view that fits insets
   * of type {@link Type#ime()}.

And I couldn't figure out how to use the new OnApplyWindowInsetsListener to achieve the same effect. Here is my current BottomSheetDialog fragment:

public class BottomSheetDialog extends BottomSheetDialogFragment {

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

//      Adding this line works, but it's deprecated in API 30
//      getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
      
        getDialog().getWindow().setDecorFitsSystemWindows(false);
        view = inflater.inflate(R.layout.fragment_bottom_dialog_cash, container, false);
        view.setOnApplyWindowInsetsListener((v, insets) -> {
            Log.d("dialog", "onCreateView: ");
            Insets imeInsets = insets.getInsets(WindowInsets.Type.ime());
            v.setPadding(0,0,0,imeInsets.bottom);
            return insets;
        });
        return view;
    }

I use an onclicklistener in another fragment to show this dialog. Code in Another fragment

    @Override
    public void onItemClick(int position) {
        BottomSheetDialog dialog = new BottomSheetDialog();
        dialog.show(getParentFragmentManager(), "BottomSheetDialog");
    }

In fact, the log indicates that the listener is never triggered when the soft keyboard pop up. FYI, I'm following this video and this blog.

After more research, I find out that if I use viewBinding and replace view with bind.getRoot(), then everything works fine. I'm not sure why (maybe I should use in onViewCreated instead of onCreateView ?) but the code should be helpful for people having the same issue.

// NOTE: you have to set this in the activity instead of fragment.
getWindow().setDecorFitsSystemWindows(false);

// Only work with API30 or above!
bind.getRoot().setOnApplyWindowInsetsListener((v, insets) -> { 
    imeHeight = insets.getInsets(WindowInsets.Type.ime()).bottom;
    bind.getRoot().setPadding(0, 0, 0, imeHeight);
    return insets;
});

One thing to be noticed is that setDecorFitsSystemWindows(false) means the app (you) are responsible for all the system windows includes the status bar and navigation bar.

I also find the tutorials linked down below are very useful, please check if you wanna know more about windowInsets and new animation callback.

Compat Version

WindowCompat.setDecorFitsSystemWindows(window, false)
ViewCompat.setOnApplyWindowInsetsListener(rootView()) { _, insets ->
    val imeHeight = insets.getInsets(WindowInsetsCompat.Type.ime()).bottom
    rootView().setPadding(0, 0, 0, imeHeight)
    insets
}

Or use Insetter library

 WindowCompat.setDecorFitsSystemWindows(window, false)
 rootView().applyInsetter {
        type(ime = true) {
            padding()
        }
    }

The only thing that seemed to do the trick for me was setting the style of the BottomSheetDialog to use the following:

<style name="BottomSheetDialogTheme" parent="Theme.MaterialComponents.Light.BottomSheetDialog">
  <item name="android:windowIsFloating">false</item>
  <item name="android:windowSoftInputMode">adjustResize|stateVisible</item>
</style>
