在android开发中ListView是比较常用的组件，它以列表的形式展示具体内容，并且能够根据数据的长度自适应显示。
main.xml布局文件
<? xml version = " 1.0 " encoding = " utf-8 " ?>
< LinearLayout android:id = " @+id/LinearLayout01 "
android:layout_width = " fill_parent " android:layout_height = " fill_parent "
xmlns:android = " http://schemas.android.com/apk/res/android " >
< ListView android:layout_width = " wrap_content "
android:layout_height = " wrap_content "
android:id = " @+id/MyListView " >
</ ListView >
</ LinearLayout >
my_listitem.xml布局文件
<? xml version = " 1.0 " encoding = " utf-8 " ?>
< LinearLayout android:layout_width = " fill_parent "
xmlns:android = " http://schemas.android.com/apk/res/android "
android:orientation = " vertical "
android:layout_height = " wrap_content "
android:id = " @+id/myListItem "
android:paddingBottom = " 3dip "
android:paddingLeft = " 10dip " >
< TextView android:layout_height = " wrap_content "
android:layout_width = " fill_parent "
android:id = " @+id/itemTitle "
android:textSize = " 20dip " >
</ TextView >
< TextView android:layout_height = " wrap_content "
android:layout_width = " fill_parent "
android:id = " @+id/itemText " >
</ TextView >
</ LinearLayout >
LsActivity类
package com.ljq.ls;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleAdapter;
public class LsActivity extends Activity {
private ListView list = null ;
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.main);
list = (ListView) findViewById(R.id.MyListView);
// 组织数据源
List < HashMap < String, String >> mylist = new ArrayList < HashMap < String, String >> ();
for ( int i = 0 ;i < 10 ;i ++ ) {
HashMap < String, String > map = new HashMap < String, String > ();
map.put( " itemTitle " , " This is Title " );
map.put( " itemText " , " This is text " );
mylist.add(map);
}
// 配置适配器
SimpleAdapter adapter = new SimpleAdapter( this ,
mylist, // 数据源
R.layout.my_listitem, // 显示布局
new String[] { " itemTitle " , " itemText " }, // 数据源的属性字段
new int [] {R.id.itemTitle,R.id.itemText}); // 布局里的控件id
// 添加并且显示
list.setAdapter(adapter);
}
}
运行结果
