android – 如何在列表视图中使项目可点击？

我一直在努力寻找解决方案,但收效甚微.
我必须显示一个包含项目列表的弹出窗口.
我能够显示窗口,但单击列表视图中的项目时未调用onitemclicklistener.任何有关此问题的帮助将不胜感激.

谢谢

EDIT1：

public class PopUpWindowActivity extends Activity {
 
    /** Called when the activity is first created. */
    String[] countries = new String[] {
        "India","USA","Canada"
    };
 
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout ll = new LinearLayout(this);
        ListView lv = new ListView(this);
        lv.setAdapter(new ArrayAdapter < String > (this,android.R.layout.simple_list_item_1,countries));
        lv.setOnItemClickListener(new OnItemClickListener() {
 
                public void onItemClick(AdapterView <? > arg0,View arg1,int arg2,long arg3) {
                    Log.v("clicked",(String)((TextView) arg1).getText());
                }
 
            });
        ll.addView(lv);
        setContentView(ll);
    }
}

在上面的代码中,我试图创建一个布局,其中我添加了一个列表视图.这使列表视图不再可单击.我必须这样做因为,我正在尝试实现一个弹出窗口,其中应该有多个项目以及列表视图.

//ListviewActivity.java

package com.anl.lk;
 
 public class ListviewActivity extends ListActivity { 
 
     static final String[] COUNTRIES = new String[] {
 
         "Afghanistan","Albania","Algeria","American Samoa","Andorra","Angola","Anguilla","Antarctica","Antigua and Barbuda","Argentina","Armenia","Aruba","Australia","Austria","Azerbaijan","Bahrain","Bangladesh","Barbados","Belarus","Belgium","Belize","Benin","Bermuda","Bhutan","Bolivia","Bosnia and Herzegovina","Botswana","Bouvet Island","Brazil","British Indian Ocean Territory"
     };
 
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setListAdapter(new ArrayAdapter < String > (this,COUNTRIES));
         getListView().setTextFilterEnabled(true);
     }
 
     @Override
     protected void onListItemClick(ListView l,View v,int position,long id) {
         // TODO Auto-generated method stub
         super.onListItemClick(l,v,position,id);
 
         new AlertDialog.Builder(this)
             .setTitle("Hello")
             .setMessage("from " + getListView().getItemAtPosition(position))
             .setPositiveButton("OK",new DialogInterface.OnClickListener() {
                 public void onClick(DialogInterface dialog,int which) {}
             })
             .show();
 
         Toast.makeText(ListviewActivity.this,"ListView: " + l.toString() + "\n" +
             "View: " + v.toString() + "\n" +
             "position: " + String.valueOf(position) + "\n" +
             "id: " + String.valueOf(id),Toast.LENGTH_LONG).show();
     }
 
 }

//第一页

package com.anl.lk;
 
public class FirstPage extends Activity {
 
    @override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {
 
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent sam = new Intent(FirstPage.this,ListviewActivity.class);
                    startActivity(sam);
 
                }
            });
    }
}

//清单文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
