通过布局文件来显示ListView内容并注册 ListView事件

1：layout/vlist.xml是我们的布局文件，在这里一定要对首节点加上

android:descendantFocusability="blocksDescendants" 这一属性，如果不加这一属性那么ListView就会获取不到点击事件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:descendantFocusability="blocksDescendants" >
    <ImageView
        android:id="@+id/imgNf"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <TextView
        android:id="@+id/titleNf"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textIsSelectable="true"/>

</LinearLayout>

2：activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView 
        android:id="@+id/lvList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"></ListView>

</RelativeLayout>

3:MainActivity.java

public class MainActivity extends Activity {
    private List<Map<String,Object>>list=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        setContentView(R.layout.activity_main);
        
        ListView lv=(ListView)findViewById(R.id.lvList);
        lv.setAdapter(initAdapter());
        //注册点击事件
        lv.setOnItemClickListener(new OnItemClickListener(){
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                String title=list.get(arg2).get("title").toString();
                Toast.makeText(MainActivity.this, title, Toast.LENGTH_SHORT).show();
            }
        });
    }
    
    
    public SimpleAdapter initAdapter(){
        SimpleAdapter simpleAdapter=new SimpleAdapter(
                MainActivity.this,
                getData(),
                R.layout.vlist,
                new String[]{"title","img"},
                new int[]{R.id.titleNf,R.id.imgNf});
        return simpleAdapter;
    }

    private List<Map<String,Object>>getData(){
        list=new ArrayList<Map<String,Object>>();
        
        Map<String,Object>map=new HashMap<String,Object>();
        map.put("title", "This is a test 1");
        map.put("img",R.drawable.ic_launcher);
        list.add(map);
        
        map=new HashMap<String,Object>();
        map.put("title", "This is a test 2");
        map.put("img",R.drawable.ic_launcher);
        list.add(map);
        
        return list;
    }
    

}
