java - 如何关闭充气层？

Question

我在充气层上制作了关闭按钮。当我单击该按钮时，我想关闭这个膨胀的层。我该如何解决这个问题

我使用了Rl.setVisibility(View.GONE);但是当我重新启动此方法时，它无法正常工作。(不同的层出来了...所有按钮都不起作用)

public void layer(){
    final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final RelativeLayout Rl = (RelativeLayout) inflater.inflate(R.layout.menu_bookmark, null);
    //Rl.setBackgroundColor(Color.parseColor("#99000000"));
    final RelativeLayout.LayoutParams paramRl = new RelativeLayout.LayoutParams
            (LinearLayout.LayoutParams.MATCH_PARENT, WRAP_CONTENT);

    addContentView(Rl, paramRl);
    final String current_url = webView.getUrl();
    final Button btn_add = (Button) findViewById(R.id.btn_add);
    final Button btn_out = (Button) findViewById(R.id.btn_out);

    final EditText editText = (EditText) findViewById(R.id.edit_input);
    editText.setText(current_url);
    final ListView listView = (ListView) findViewById(R.id.lv_bookmark);
    final ArrayList<String> arrayList = new ArrayList<String>();
    final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.menu_bookmark_row, arrayList);
    listView.setAdapter(arrayAdapter);
    btn_add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (editText.getText().toString().length() > 0) {
                String inputStr = editText.getText().toString();
                arrayList.add(inputStr);
                arrayAdapter.notifyDataSetChanged();
            }
        }
    });
    btn_out.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // <--I NEED HELP!!!!!
        }
    });

parentLinearLayout.removeView((View) v.getParent()); https://www.androidtutorialpoint.com/basics/dynamically-add-and-remove-views-in-android/
