Android Whatsapp附件的窗口如何覆盖键盘？

我正在处理一个类似的问题来开发我的聊天，我正在检查whatsapp是如何解决这个问题的，以获得解决这个问题的想法

在手机和对话中，当键盘在屏幕上并单击附件时，“附件”窗口将覆盖keboard，如下图所示。它看起来也像是它下面的活动冻结了。你可以看看EditText上的斜线，看起来是冻结

我想知道WP是如何覆盖键盘的，为什么它下面的活动看起来像是冻结的，提前谢谢

/在不使用任何库的情况下使用以下代码Snipet/

您可以使用BottomSheetDialog执行以下操作：示例：哇，好人，似乎是正确的答案！！真是太阳穴了！

   action_attach.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openDialog();
        }
    });


  private void openDialog() {
    LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    // inflate the custom popup layout
    final View inflatedView;

    inflatedView = layoutInflater.inflate(R.layout.custom_dialog_options_menu, null, false);

    LinearLayout layoutGallery;
   layoutGallery = (LinearLayout) inflatedView.findViewById(R.id.layoutGallery);
    layoutGallery.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FloatingView.dismissWindow();
        }
    });

    FloatingView.onShowPopup(this, inflatedView);
  }
