我是新來的android和我想要集成auto complete text view內彈出窗口。但是自動完成操作在彈出窗口內不起作用。如果我把自動完成文本視圖彈出自動完成工作正常。彈出窗口的

XML代碼：

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

    <LinearLayout 
     android:id="@+id/popup" 
     android:layout_width="300dp" 
     android:layout_height="match_parent" 
     android:layout_gravity="center_horizontal" 
     android:gravity="center_horizontal" 
     android:orientation="vertical" 
     tools:ignore="UselessParent" > 

     <FrameLayout 
    android:id="@+id/innertop" 
    android:layout_width="match_parent" 
    android:layout_height="55dp" 
     > 


    <AutoCompleteTextView 
     android:id="@+id/listitem" 
     style="@style/CodeFont" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="4dp" 
     android:background="@drawable/border" 
     android:hint="@string/search_products_" 
     android:textSize="12sp" 
     android:typeface="serif" /> 

    <Button 
     android:id="@+id/searchbtn1" 
     android:layout_width="32dp" 
     android:layout_height="32dp" 
     android:layout_gravity="center_vertical|right" 
     android:layout_marginRight="10dp" 
     android:layout_marginBottom="1dp" 
     android:background="@drawable/search_icon" /> 

</FrameLayout> 

    </LinearLayout> 

</LinearLayout> 

活動Java代碼：

final TextView btnOpenPopup1 = (TextView)findViewById(R.id.textView6); 
           btnOpenPopup1.setOnClickListener(new TextView.OnClickListener(){ 

         @Override 
          public void onClick(View arg0) { 
          LayoutInflater layoutInflater 
          = (LayoutInflater)getBaseContext() 
          .getSystemService(LAYOUT_INFLATER_SERVICE); 
          View popupView = layoutInflater.inflate(R.layout.login_popup, null); 
            final PopupWindow popupWindow = new PopupWindow(
             popupView, 
             LayoutParams.WRAP_CONTENT, 
              LayoutParams.WRAP_CONTENT); 

            popupWindow.setFocusable(true); 
            popupWindow.showAsDropDown(btnOpenPopup, -50, -70); 

我已經在谷歌搜索。我可以找到警報對話框的解決方案，但不適用於模式窗口。如何解決這個問題？

@Override public void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; setContentView（R.layout.activity_my）;

final Button btnOpenPopup = (Button)findViewById(R.id.openpopup);
