android开发之ArrayAdapter的使用

<?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">
<ListView  
    android:id="@+id/list1"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/TextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"    
/>

setContentView(R.layout.main);
//实例化列表项
ListView list1 = (ListView) findViewById(R.id.list1);
// 定义一个数组
String[] arr1 = { "孙悟空", "猪八戒", "牛魔王" };
// 将数组包装ArrayAdapter
/*
 * ArrayAdapter<String>(Context context, int textViewResourceId, String[] objects)
 * context：
 * textViewResourceId:TextView的布局文件
 * objects:需要传入的数组
 */
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>
    (this, R.layout.array_item, arr1);
// 为ListView设置Adapter
list1.setAdapter(adapter1);
