1.布局文件有一个listview和listview_item

第一个布局文件

<?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"
    >
<ListView
android:id="@+id/listview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:divider="#ff0000"
    android:dividerHeight="2dp"
    />
</LinearLayout>

第二个布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="match_parent"
  android:layout_height="80dp">
  <TextView
   android:layout_marginLeft="30dp"
   android:layout_width="100dp"
   android:layout_height="wrap_content"
   android:id="@+id/textName"
   android:textSize="30dp"/>
  <TextView
   android:layout_marginLeft="30dp"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:id="@+id/textPhone"
   android:textSize="30dp"/>
</LinearLayout>

java代码

public class MainActivity extends Activity {

private ListView listView;
private String[] names = { "张三", "李四", "王五" };
private String[] phones = { "12345", "3333333", "55555555" };
List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  listView = (ListView) findViewById(R.id.listview);
  loadData();
  SimpleAdapter adapter = new SimpleAdapter(this, list, R.layout.item,
    new String[] { "name", "phone" }, new int[] { R.id.textName,
      R.id.textPhone });
  listView.setAdapter(adapter);
}

private void loadData() {
     for (int i = 0; i < names.length; i++) {
   Map<String,Object> map = new HashMap<String, Object>();
   map.put("name", names[i]);
   map.put("phone", phones[i]);
   list.add(map);
  }
    }

@Override
public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_main, menu);
  return true;
}

}

这就是一个简单的
