Spinner在弹出窗口中显示为下拉菜单？

如何将弹窗作为下拉菜单显示，它在对话框模式下工作正常，但是当我将它设置为下拉时，它会给我一个错误。Spinner在弹出窗口中显示为下拉菜单？

这里是我的代码

LayoutInflater layoutInflater = (LayoutInflater) getBaseContext() 
        .getSystemService(LAYOUT_INFLATER_SERVICE); 
final View popupView10 =layoutInflater.inflate(R.layout.successful_dontfollow_main, null); 
popupWindow10 = new PopupWindow(popupView10,ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT,true); 
popupWindow10.showAtLocation(popupView10, Gravity.CENTER, 0,0); 
popupWindow9.dismiss(); 
spinner1 = (Spinner) popupView10.findViewById(R.id.spinner2); 
spinner1.setAdapter(new MycustomAdapter(MainActivity.this,R.layout.popupbutton2_activity, payment));

和我的自定义适配器类

public class MycustomAdapter extends ArrayAdapter<String> 
{ 
    String[] payment={"BARCLAYS XXXX-XXX-XX89 ","BANK OF AMERICA XXXX-XXX-XX89","HSBC XXXX-XXX-XX89 "}; 

    public MycustomAdapter(Context context, int textViewResourceId, 
          String[] objects) { 
     super(context, textViewResourceId, objects); 
     // TODO Auto-generated constructor stub 
    }

当我将它设置为降下来，我得到这个错误

MainActivity.this.runOnUiThread(new Runnable() { 
     public void run() { 
     //Do your UI operations like dialog opening or Toast here 


        LayoutInflater layoutInflater = (LayoutInflater) getBaseContext() 
        .getSystemService(LAYOUT_INFLATER_SERVICE); 
       final View popupView10 =layoutInflater.inflate(R.layout.successful_dontfollow_main, null);

不起作用相同的错误 – Redman

@Redman检查更新的答案。 –

更新了一个也不起作用，同样的错误 – Redman

使用下面的代码，以显示弹出式窗口的微调下拉：

活动类：

public class SpinnerActivity extends Activity { 

private LinearLayout layout; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_spinner); 

    Spinner s; 
    layout = (LinearLayout) findViewById(R.id.popup); 
    layout.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      PopupWindow popUp= showDropDownData(); 
      popUp.showAsDropDown(view, 0, 0); 
     } 
    }); 
} 

private PopupWindow showDropDownData() { 
    PopupWindow popupWindow = new PopupWindow(this); 

    //Initializing data from string.xml file 
    String[] data={"BARCLAYS XXXX-XXX-XX89 ","BANK OF AMERICA XXXX-XXX-XX89","HSBC XXXX-XXX-XX89 "}; 
    CustomSpinnerAdapter adapter = new CustomSpinnerAdapter(this, data); 

    // the drop down list is a list view 
    ListView listViewSort = new ListView(this); 

    // set our adapter and pass our pop up window contents 
    listViewSort.setAdapter(adapter); 

    // set on item selected 
    // listViewSort.setOnItemClickListener(onItemClickListener()); 

    popupWindow.setFocusable(true); 
    popupWindow.setWidth(layout.getWidth()); 
    popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT); 

    popupWindow.setContentView(listViewSort); 
    return popupWindow; 
} 
}

下面

是XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/popup" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginLeft="10dp" 
android:layout_marginRight="10dp" 
android:layout_marginTop="5dp" 
android:background="@drawable/layout_background" 
android:padding="4dp"> 


<ImageView 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:src="@android:drawable/btn_star_big_on" /> 

<TextView 
    android:id="@+id/openPopup" 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:gravity="left|center_vertical" 
    android:paddingLeft="10dp" 
    android:text="popup window" /> 

</LinearLayout>

您可以使用onItemClickListener（）从下拉列表中选择一个项目。
