最终的效果图如下(点击一行之后,如右图)
这里需要两个布局文件,一个是main.xml,控制整个屏幕的布局,另一个是需要显示的内容布局,即ListView
这是main.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="@id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
android:scrollbars="vertical"
/>
</LinearLayout>
</LinearLayout>
这是user.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:paddingTop="1dip"
android:paddingBottom="1dip"
>
<TextView
android:id="@+id/user_name"
android:layout_width="130dip"
android:layout_height="30dip"
android:textSize="10pt">
</TextView>
<TextView
android:id="@+id/user_ip"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textSize="10pt">
</TextView>
</LinearLayout>
这是ListActivity.java文件
package com.listView;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.SimpleAdapter;
public class ListView 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>>();
HashMap<String,String> map1 = new HashMap<String,String>();
HashMap<String,String> map2 = new HashMap<String,String>();
HashMap<String,String> map3 = new HashMap<String,String>();
map1.put("user_name", "zhangsan");
map1.put("user_ip", "192.168.12.10");
map2.put("user_name", "lisi");
map2.put("user_ip", "192.168.10.15");
map3.put("user_name", "wangwu");
map3.put("user_ip", "192.168.11.18");
list.add(map1);
list.add(map2);
list.add(map3);
SimpleAdapter listAdapter = new SimpleAdapter(this,list,R.layout.user,
new String[]{"user_name","user_ip"},
new int[]{R.id.user_name,R.id.user_ip});
setListAdapter(listAdapter);
}
@Override
protected void onListItemClick(android.widget.ListView l, View v,
int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
System.out.println("------id------"+id);
System.out.println("----position----"+position);
}
}
