PopupWindow + ListView + OnItemClick invalid

Code is as follows:

@Override
 	protected void onCreate(Bundle savedInstanceState) {
 		super.onCreate(savedInstanceState);
 		setContentView(R.layout.activity_main);
 		final Button button1 = (Button) findViewById(R.id.button1);
 
 		button1.setOnClickListener(new OnClickListener() {
 
 			public void onClick(View v) {
 				// TODO Auto-generated method stub
 				// 生成ListView
 				ListView listview = new ListView(MainActivity.this);
 				String strs = new String;
 				strs = "asfsafdasdf";
 				strs = "桂　地要仍地沃尔夫仍";
 				strs = "asfsafdasdf";
 				 ArrayAdapter<String> adapter=new
 				 ArrayAdapter<String>(MainActivity.this,R.layout.common_poplist_item_single_textview,R.id.content,strs);
 //				ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.common_poplist_item_single_textview, strs);
 				listview.setAdapter(adapter);
 				listview.setOnItemClickListener(new OnItemClickListener() {
 
 					public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
 						// TODO Auto-generated method stub
 						System.out.println(position);
 					}
 				});
 
 				PopupWindow window = new PopupWindow(MainActivity.this);
 				// 设置宽高
 				window.setWidth(200);
 				window.setHeight(120);
 				// 填充
 				window.setContentView(listview);
 				// 外部可部
 				window.setOutsideTouchable(true);
 				// 加了下面这行，onItemClick才好用
 				window.setFocusable(true);
 				window.showAsDropDown(button1);
 
 			}
 		});
 	}

has been tested and found 2.3 OnItemClick can trigger on a real machine .. but in the real machine to test 4.1, 4.2 No response .. trouble you have to help me verify whether this is true, what is the solution.
--- --- Solution --------------------------------------------
click a button displayed directly popwindow like

you to write it out to try it

landlord, I at 4.1 effective ah, this is my code http://blog.csdn.net/xiaanming/article/details/9121383

you want to achieve this click event interface got
------ For reference only ------------------------ ---------------

listview.setOnItemClickListener(new OnItemClickListener() {
  
                     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                         // TODO Auto-generated method stub
                         System.out.println(position);
                     }
                 });

this count to achieve it

, I think there's setOnItemClickListener write listview better on the inside should not okay

@Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         // 生成ListView
                 ListView listview = new ListView(MainActivity.this);
                 String strs = new String;
                 strs = "asfsafdasdf";
                 strs = "桂　地要仍地沃尔夫仍";
                 strs = "asfsafdasdf";
                  ArrayAdapter<String> adapter=new
                  ArrayAdapter<String>(MainActivity.this,R.layout.common_poplist_item_single_textview,R.id.content,strs);
 //                ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, R.layout.common_poplist_item_single_textview, strs);
                 listview.setAdapter(adapter);
                 listview.setOnItemClickListener(new OnItemClickListener() {
  
                     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                         // TODO Auto-generated method stub
                         System.out.println(position);
                     }
                 });
         final Button button1 = (Button) findViewById(R.id.button1);
  
         button1.setOnClickListener(new OnClickListener() {
  
             public void onClick(View v) {
                 // TODO Auto-generated method stub
                 
  
                 PopupWindow window = new PopupWindow(MainActivity.this);
                 // 设置宽高
                 window.setWidth(200);
                 window.setHeight(120);
                 // 填充
                 window.setContentView(listview);
                 // 外部可部
                 window.setOutsideTouchable(true);
                 // 加了下面这行，onItemClick才好用
                 window.setFocusable(true);
                 window.showAsDropDown(button1);
  
             }
         });
     }
