将视图添加到RecyclerView

Question

我尝试将视图添加到RecyclerView时，点击Button在ViewHolder中。

当点击Button在ViewHolder3，一个视图（视图中添加更多）将增加并且出现上述情况类似的图像。

ViewAddMore将固定在那里，RecyclerView可以正常滚动。

我试过但没有找到任何解决方案，我的问题; 对我的问题有任何建议吗？

请使用PopupWindow显示此视图。

// get a reference to the already created main layout 
    LinearLayout mainLayout = (LinearLayout) findViewById(R.id.activity_main_layout); 

    // inflate the layout of the popup window 
    LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); 
    View popupView = inflater.inflate(R.layout.popup_window, null); 

    // create the popup window 
    int width = LinearLayout.LayoutParams.WRAP_CONTENT; 
    int height = LinearLayout.LayoutParams.WRAP_CONTENT; 
    boolean focusable = true; // lets taps outside the popup also dismiss it 
    final PopupWindow popupWindow = new PopupWindow(popupView, width, height, focusable); 

    // show the popup window 
    popupWindow.showAtLocation(mainLayout, Gravity.CENTER, 0, 0); 

    // dismiss the popup window when touched 
    popupView.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      popupWindow.dismiss(); 
      return true; 
     } 
    });
