ListView的一个简单实例

首先是布局文件

1.main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
        <LinearLayout xmlns:android=""
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     >

     <ListView
         android:id="@id/android:list"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         android:drawSelectorOnTop="false"
         android:scrollbars="vertical"
         />
    </LinearLayout>

</LinearLayout>

然后是user.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dip"
    >
    <TextView
        android:id="@+id/textUsrName"
        android:layout_width="180dip"
        android:layout_height="30dip"
        android:text="@string/usr_name"
        android:textSize="10pt"
        android:singleLine="true"
        android:gravity="left"

    />
    <TextView
        android:id="@+id/textUsrAddr"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="@string/app_addr"
        android:textSize="10pt"
        android:gravity="right"

    />
</LinearLayout>

string.xml中用到的一些变量

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, activity01!>
    <string name="app_name">listview</string>
    <string name="usr_name">用户名</string>
    <string name="app_addr">IP地址</string>
</resources>

2.再就是java代码

package listview.listview;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

public class activity01 extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ArrayList<HashMap<String,String>> list = new
        ArrayList<HashMap<String,String>>();
        //创建表

        HashMap<String,String> map1 = new HashMap<String,String>();
        HashMap<String,String> map2 = new HashMap<String,String>();
        HashMap<String,String> map3 = new HashMap<String,String>();
        //初始化表数据

        map1.put("textUsrName", "小白兔");
        map1.put("textUsrAddr", "79.3.5.6");
        map2.put("textUsrName", "小黑");
        map2.put("textUsrAddr", "39.3.5.5");
        map3.put("textUsrName", "小红兔子");
        map3.put("textUsrAddr", "16.3.7.6");
        //将表添加进list

        list.add(map1);
        list.add(map2);
        list.add(map3);
        //新建容器adapter

        SimpleAdapter listAdapter = new SimpleAdapter(this,list,R.layout.user,
                new String[]{"textUsrName","textUsrAddr"},new
                int []{R.id.textUsrName,R.id.textUsrAddr});
        setListAdapter(listAdapter);


    }


    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub

        super.onListItemClick(l, v, position, id);
        System.out.println("id--------------"+(id+1));
        System.out.println("position--------------"+position);
        Toast.makeText(getApplicationContext(),
                "你点击了第"+(id+1)+"个单位",
                Toast.LENGTH_SHORT).show();
    }

}
