Android ListView用法(1)，不用ListActivity实现

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


			}

		});

	}
