無法在PopUp窗口中的視圖上設置onClickListener：

Question

我得到元素的標記和ID，但無法設置可見性或onClickListener。你能告訴我爲什麼嗎？代碼： onClickListener和知名度，這應該使視圖不可見，在clicklistener應該說DS（我第一次嘗試的一個然後其他）：

ViewGroup layoutHolder = (ViewGroup) inflater.inflate(context.getResources().getIdentifier("settings", 
           "layout", context.getPackageName()), (ViewGroup) this.findViewById(getResources().getIdentifier("settings", 
         "id", getPackageName())), false); 
layoutHolder.findViewById(R.id.msettings).setOnClickListener(handler) 
View.OnClickListener handler = new View.OnClickListener() { 
     public void onClick(View v) { 
     Toast.makeText(getApplicationContext(), "ds", Toast.LENGTH_SHORT).show(); 
    }; 

彈出：

LayoutInflater layoutInflater 
        = (LayoutInflater)getBaseContext() 
        .getSystemService(LAYOUT_INFLATER_SERVICE); 
      View popupView = layoutInflater.inflate(R.layout.settings, null); 
      final PopupWindow popupWindow = new PopupWindow(
        popupView, 
        LinearLayout.LayoutParams.WRAP_CONTENT, 
        LinearLayout.LayoutParams.WRAP_CONTENT); 
      Bitmap bitmap = null; 
      popupWindow.setBackgroundDrawable(new BitmapDrawable(getApplicationContext().getResources(), bitmap)); 
      popupWindow.setOutsideTouchable(true); 
      popupWindow.showAsDropDown(v, 50, 11); 

XML：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="wrap_content"

請嘗試像下面的代碼。

LayoutInflater layoutInflater 
        = (LayoutInflater)getBaseContext() 
        .getSystemService(LAYOUT_INFLATER_SERVICE); 
      View popupView = layoutInflater.inflate(R.layout.settings, null); 

popupView.findViewById(R.id.msettings).setOnClickListener(handler) 
View.OnClickListener handler = new View.OnClickListener() { 
     public void onClick(View v) { 
     Toast.makeText(getApplicationContext(), "ds", Toast.LENGTH_SHORT).show(); 
    }; 
final PopupWindow popupWindow = new PopupWindow(
        popupView, 
        LinearLayout.LayoutParams.WRAP_CONTENT, 
        LinearLayout.LayoutParams.WRAP_CONTENT); 
      Bitmap bitmap = null; 
      popupWindow.setBackgroundDrawable(new BitmapDrawable(getApplicationContext().getResources(), bitmap)); 
      popupWindow.setOutsideTouchable(true); 
      popupWindow.showAsDropDown(v, 50, 11);
