怎样在Android中ListView与ArrayAdapter配合使用

<?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">
<!-- 注意这里的Android:id是使用内置的-->
<ListView Android:id="@android:id/list "
Android:layout_width="fill_parent"
Android:layout_height="wrap_content"></ListView></LinearLayout>

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String[]items ={"aaa","bbbb","cccc"};
ArrayAdapter arrayAdapter = new ArrayAdapter(this,Android.R.layout.simple_list_item_1 ,items);
setListAdapter(arrayAdapter); }
