怎样才能让BottomAppBar贴在键盘的顶部？颤动

final View activityRootView = findViewById(android.R.id.content);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
        Rect r = new Rect();
        activityRootView.getWindowVisibleDisplayFrame(r);
        int screenHeight = activityRootView.getRootView().getHeight();

        // 计算键盘高度
        int keyboardHeight = screenHeight - r.bottom;

        // 根据键盘高度调整BottomAppBar的位置
        CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) bottomAppBar.getLayoutParams();
        params.bottomMargin = keyboardHeight;
        bottomAppBar.setLayoutParams(params);
    }
});
