方法,在xml文件中添加一个ListView,然后在MainActivity中
private ListView listView;
private ArrayAdapter<String> arr_adapter;
listView = (ListView) findViewById(R.id.listView1);
String[] arr_data = {"明明","丽媛", "彭辉", "倩倩", "迪迪","李琰", "赛磊"};
/*
* 新建一个适配器
* ArrayAdapter(上下文,当前ListView加载的每一个列表项所对应的布局文件,数据源);
* 适配器加载数据源
*/
arr_adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arr_data);
//视图加载适配器
listView.setAdapter(arr_adapter);
activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <ListView android:id="@+id/listView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" > </ListView> </RelativeLayout>
