代码如下:
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;
/**
* A list view example where the
* data comes from a cursor, and a
* SimpleCursorListAdapter is used to map each item to a two-line
* display.
*/
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);
}
}
