Answer 1

I ended up getting a satisfactory result with the following code: use this in setupDialog(dialog: Dialog, style: Int) method in BottomSheetFragment

dialog.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
    dialog.setOnShowListener {
        val bottomSheetDialog = dialog as BottomSheetDialog
        val bottomSheet = bottomSheetDialog.findViewById<View>(android.support.design.R.id.design_bottom_sheet) as FrameLayout?
        BottomSheetBehavior.from(bottomSheet!!).state = BottomSheetBehavior.STATE_EXPANDED
    }

Answer 2

Got this answer from here

As I too had the same issue in one of my projects,

Use this in onCreateDialog in BottomSheetFragment

new KeyboardUtil(getActivity(), rootView);

By using the below class

public class KeyboardUtil {
    private View decorView;
    private View contentView;
    //a small helper to allow showing the editText focus
    ViewTreeObserver.OnGlobalLayoutListener onGlobalLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            Rect r = new Rect();
            //r will be populated with the coordinates of your view that area still visible.
            decorView.getWindowVisibleDisplayFrame(r);

            //get screen height and calculate the difference with the useable area from the r
            int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
            int diff = height - r.bottom;

            //if it could be a keyboard add the padding to the view
            if (diff != 0) {
                // if the use-able screen height differs from the total screen height we assume that it shows a keyboard now
                //check if the padding is 0 (if yes set the padding for the keyboard)
                if (contentView.getPaddingBottom() != diff) {
                    //set the padding of the contentView for the keyboard
                    contentView.setPadding(0, 0, 0, diff);
                }
            } else {
                //check if the padding is != 0 (if yes reset the padding)
                if (contentView.getPaddingBottom() != 0) {
                    //reset the padding of the contentView
                    contentView.setPadding(0, 0, 0, 0);
                }
            }
        }
    };

    public KeyboardUtil(Activity act, View contentView) {
        this.decorView = act.getWindow().getDecorView();
        this.contentView = contentView;

        //only required on newer android versions. it was working on API level 19
        if (Build.VERSION.SDK_INT >= 19) {
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
        }
    }

    /**
     * Helper to hide the keyboard
     *
     * @param act
     */
    public static void hideKeyboard(Activity act) {
        if (act != null && act.getCurrentFocus() != null) {
            InputMethodManager inputMethodManager = (InputMethodManager) act.getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(act.getCurrentFocus().getWindowToken(), 0);
        }
    }

    public void enable() {
        if (Build.VERSION.SDK_INT >= 19) {
            decorView.getViewTreeObserver().addOnGlobalLayoutListener(onGlobalLayoutListener);
        }
    }

    public void disable() {
        if (Build.VERSION.SDK_INT >= 19) {
            decorView.getViewTreeObserver().removeOnGlobalLayoutListener(onGlobalLayoutListener);
        }
    }
}
