Keyboard hides BottomSheetDialogFragment

Question

There are more fields below the keyboard. This happened when i updated the support library. I know it\'s Kotlin but it looks almost the same as java. How do I fix this issue

You can use the next class:

import android.graphics.Rect; 
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.design.widget.BottomSheetBehavior;
import android.support.design.widget.BottomSheetDialog;
import android.support.design.widget.BottomSheetDialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;

public class TestBottomSheetDialog extends BottomSheetDialogFragment {

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View fragmentView = LayoutInflater.from(getContext()).inflate(R.layout.fragment_bottom_sheet, container, false);
        if (getDialog().getWindow() != null) {
           getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        }
        if (getActivity() != null) {
            View decorView = getActivity().getWindow().getDecorView();
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
                Rect displayFrame = new Rect();
                decorView.getWindowVisibleDisplayFrame(displayFrame);
                int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
                int heightDifference = height - displayFrame.bottom;
                if (heightDifference != 0) {
                    if (fragmentView.getPaddingBottom() != heightDifference) {
                        fragmentView.setPadding(0, 0, 0, heightDifference);
                    }
                } else {
                    if (fragmentView.getPaddingBottom() != 0) {
                        fragmentView.setPadding(0, 0, 0, 0);
                    }
                }
            });
        }
        getDialog().setOnShowListener(dialog -> {
            BottomSheetDialog d = (BottomSheetDialog) dialog;
            View bottomSheetInternal = d.findViewById(android.support.design.R.id.design_bottom_sheet);
            if (bottomSheetInternal == null) return;
             BottomSheetBehavior.from(bottomSheetInternal).setState(BottomSheetBehavior.STATE_EXPANDED);
        });
        return fragmentView;
    }
}
