Android列表實現(xiàn)(2)_游標列表案例講解

 更新時間:2012年12月30日 11:50:54   作者:  
最近開始學(xué)習(xí)android的ui 游標列表實現(xiàn),先上幾個相關(guān)的例子,后續(xù)還會有更新,感興趣的朋友可以研究下
復(fù)制代碼 代碼如下:

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);
}

}

注意 該例子要給程序賦予權(quán)限
復(fù)制代碼 代碼如下:

<uses-permission android:name="android.permission.READ_CONTACTS"/>

simple_list_item_2.xml
復(fù)制代碼 代碼如下:
