一個容易讀取手機聯繫人的方法, Activity.managedQuery()

本例子通過調用 Activity.managedQuery() 方法讀取手機聯繫人.

package com.AndroidContacts;



import android.app.ListActivity;

import android.database.Cursor;

import android.os.Bundle;

import android.provider.Contacts.People;

import android.widget.SimpleCursorAdapter;



public class AndroidContactsActivity extends ListActivity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        

        String[] projection = {People._ID, People.NAME};

        Cursor cursor = managedQuery(

        		People.CONTENT_URI,		//Uri				

        		projection, 			//projection

        		null, 					//selection

        		null, 					//selection arguments

        		People.NAME);			//Sort by



        String[] name = new String[] {People.NAME};

        int[] text1 = new int[] {android.R.id.text1};

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,

        		android.R.layout.simple_list_item_1, 

        		cursor, 

        		name, 

        		text1);

        

        setListAdapter(adapter);

    }

}

最後, 需要修改 AndroidManifest.xml 文件, 添加 "android.permission.READ_CONTACTS" 權限
