Introduction To Android Contacts

Learn to work with the Android contacts database. Basic knowledge of accessing SQLite in Android along with using Cursors is expected. See the Android SQLite and Cursor Article for more information. Google changed the contacts database moving from 1.x to 2.0 versions of Android. This tutorial will be broken into 3 sections. First covering accessing contacts in Android 2.0. The second page will deal with accessing the contacts in Android 1.6 and before. Third we'll glue it all together with a class that abstracts specific classes for each version and a set of classes to manage the data from the contact records.

Contacts 读取代码：

package com.homer.phone;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;
import android.widget.ListView;
import android.widget.SimpleAdapter;

public class phoneRead extends Activity {
	  
	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		
		showListView();
	}
	
	private void showListView(){
		ListView listView = new ListView(this);
		
		ArrayList<HashMap<String, String>> list = getPeopleInPhone2();
		SimpleAdapter adapter = new SimpleAdapter(
									this, 
									list, 
									android.R.layout.simple_list_item_2, 
									new String[] {"peopleName", "phoneNum"}, 
									new int[]{android.R.id.text1, android.R.id.text2}
								);
		listView.setAdapter(adapter);
		
		setContentView(listView);
	}
	
	private ArrayList<HashMap<String, String>> getPeopleInPhone2(){
		ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
		
        Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);		// 获取手机联系人
		while (cursor.moveToNext()) {
			HashMap<String, String> map = new HashMap<String, String>();
			
			int indexPeopleName = cursor.getColumnIndex(Phone.DISPLAY_NAME); 	// people name
			int indexPhoneNum = cursor.getColumnIndex(Phone.NUMBER);	 		// phone number

			String strPeopleName = cursor.getString(indexPeopleName);
			String strPhoneNum = cursor.getString(indexPhoneNum);

			map.put("peopleName", strPeopleName);
			map.put("phoneNum", strPhoneNum);
			list.add(map);
		}
        if(!cursor.isClosed()){
        	cursor.close();
        	cursor = null;
        }
		
        return list;
	}
}

AndroidManifest.xml 权限

记得在AndroidManifest.xml中加入android.permission.READ_CONTACTS这个permission

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

运行结果：
