[转载] Android 2.3.3 API 读取通讯录中电话号码的实例

最近开始学习Android,主要看的是《Android应用开发揭秘》,在第3章的Example_03_02是一个读取通讯录联系人姓名和电话的实例,但由于API 2.0中,每个联系人可以有多个电话(例如手机、住宅、公司、传真等),书中原有的实例在API 2.0的环境中会报错。

书中的Example_03_02代码:

View Code
package com.yarin.android.Examples_03_02;

import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.PhoneLookup;
import android.util.Log;
import android.widget.TextView;

import org.apache.commons.lang.StringUtils;

public class Activity01 extends Activity
{
    public void onCreate(Bundle savedInstanceState)
    {
        TextView tv = new TextView(this);
        String string = "";        
        super.onCreate(savedInstanceState);    
        //得到ContentResolver对象
        ContentResolver cr = getContentResolver();  
        //取得电话本中开始一项的光标
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        
        Log.i("tag",Integer.toString(cursor.getColumnCount())) ;
        Log.i("tag",StringUtils.join(cursor.getColumnNames(), ",") ) ;
        //向下移动一下光标
        while(cursor.moveToNext()) 
        { 
            //取得联系人名字
            int nameFieldColumnIndex = cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME);     
            String contact = cursor.getString(nameFieldColumnIndex); 
            //取得电话号码 (此方法会报错,因为一个联系人可能有多个联系电话)
            //int numberFieldColumnIndex = cursor.getColumnIndex(PhoneLookup._ID);    
            //String number = cursor.getString(numberFieldColumnIndex);
            //string += (contact+":"+number+"\n");
            
            //新方法获取电话号码
            String ContactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+ ContactId, null, null);
            while(phone.moveToNext())
            {                
                String PhoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                
                string += (contact +":"+ PhoneNumber +"\n");            
            }
            
        }
        cursor.close();
        //设置TextView显示的内容
        tv.setText(string);
        //显示到屏幕
        setContentView(tv);
    }
}

其中的原代码已被我注解,并改了正确的代码

如果我们只想获取手机号如何操作呢?

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId, null, null);

把以上语句改为:

Cursor phone = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + ContactId + " AND " + 
ContactsContract.CommonDataKinds.Phone.TYPE + "=" + ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);

ContactsContract.CommonDataKinds.Phone.TYPE 表示联系人电话的类型,主要对应如下:
TYPE_MOBILE : 手机号码

TYPE_HOME  : 住宅电话
TYPE_WORK : 公司电话

 

最后附加main.xml的代码

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
</LinearLayout>
