package com.test;import android.app.Activity; 
import android.content.ContentResolver; 
import android.database.Cursor;import android.os.Bundle; 
import android.provider.Contacts.People; 
public class TestContacts extends Activity {     
@Override    public void onCreate(Bundle savedInstanceState) {  
       super.onCreate(savedInstanceState);         
       setContentView(R.layout.main);        
       ContentResolver cr = getContentResolver();         
       Cursor cur = cr.query(People.CONTENT_URI, null, null, null, null);         
        if(cur.getCount()>0){            
          while (cur.moveToNext()) {                 
             String id = cur.getString(cur.getColumnIndex(People._ID));                 
             String name = cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));             
          }         
}          
} 
} 

Phone Numbers 电话号码
查询的URI换成Contacts.Phones.CONTENT_URI。
Java代码 
if (cur.getInt(cur.getColumnIndex(People.PRIMARY_PHONE_ID)) > 0) {                     
        Cursor pCur = cr.query(Contacts.Phones.CONTENT_URI,null,                            Contacts.Phones.PERSON_ID +" = ?",new String[]{id}, null); 
         int i=0;
