import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.Phones;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;
public class List3 extends ListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get a cursor with all phones
Cursor c = getContentResolver().query(Phones.CONTENT_URI, null, null, null, null);
startManagingCursor(c);
// Map Cursor columns to views defined in simple_list_item_2.xml
ListAdapter adapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_2, c,
new String[] { Phones.NAME, Phones.NUMBER },
new int[] { android.R.id.text1, android.R.id.text2 });
setListAdapter(adapter);
}
}
注意 该例子要给程序赋予权限：
代码如下:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
simple_list_item_2.xml
代码如下:
<?xml version="1.0" encoding="utf-8"?>
