ListView 中的 Android OnItemClickListener 不起作用

Question

我已经创建了一个选项卡 Activity ，当我单击特定选项卡时它工作正常，我扩展了列表 Activity 并且也获得了 ListView ，但我无法使列表中的项目可点击。代码:

package com.infra.android.views;

import java.util.ArrayList;
import java.util.HashMap;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class TopNewsActivity extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listplaceholder);

        ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();


        String xml = XMLfunctions.getTopNewsXML();
        Document doc = XMLfunctions.XMLfromString(xml);

        int numResults = XMLfunctions.numResults(doc);

        if((numResults <= 0)){
            Toast.makeText(TopNewsActivity.this, "No Result Found", Toast.LENGTH_LONG).show();  
            finish();
        }

        NodeList nodes = doc.getElementsByTagName("result");

        for (int i = 0; i < nodes.getLength(); i++) {                           
            HashMap<String, String> map = new HashMap<String, String>();    

            Element e = (Element)nodes.item(i);
            map.put("id", XMLfunctions.getValue(e, "id"));
            map.put("title", XMLfunctions.getValue(e, "title"));
            mylist.add(map);            
        }       

        ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main, new String[] { "title"}, new int[] { R.id.item_title});

        setListAdapter(adapter);

        final ListView lv = getListView();
        lv.setTextFilterEnabled(true);  
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {              
                @SuppressWarnings("unchecked")
                HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);                   
                Toast.makeText(TopNewsActivity.this, "ID '" + o.get("id") + "' was clicked.", Toast.LENGTH_LONG).show(); 

            }
        });
    }
}

当我点击该项目时，它可能会给出被点击项目的 ID，但它不起作用。

对于 ListView ，

ListView lv = (ListView) findViewById(R.id.ContainlistItems);
lv.setItemsCanFocus(false);

并且在 XML 文件中，确保为列表项中的 Textview 设置 focusable false

android:focusable="false"
android:focusableInTouchMode="false"
