android ListView 使用

首先是Layout文件:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">
    
 
    
    <!-- The frame layout is here since we will be showing either
    the empty view or the list view.  -->
    <FrameLayout
        android:layout_width="fill_parent" 
        android:layout_height="0dip"
        android:layout_weight="1" >
        <!-- Here is the list. Since we are using a ListActivity, we
             have to call it "@android:id/list" so ListActivity will
             find it -->
        <ListView android:id="@+id/main2_list"
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent"
            android:drawSelectorOnTop="false"/>
                    
    </FrameLayout>
        
</LinearLayout>

 

其次是Activity:先创建一个类继承Activitiy

重写onCreate方法

public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main2);
                //TO-DO
                ListView listView = (ListView) findViewById(R.id.main2_list);
		userAdapter = new UserAdapter(this);
		listView.setAdapter(listAdapter);
		listView.setBackgroundDrawable(null);
		listView.setOnItemClickListener(new OnItemClickListener() {
			public void onItemClick(AdapterView<?> arg0, View arg1,
					int position, long id) {
				//TO-DO
			}
		});
	}
