Answer 1

欢迎您注册一个ContentObserver从ContactsContractContentProvider适当Uri摸透更改该Uri。

Answer 2

//initially all your contact is stored in database then use this service and regiter this service in manifest 
public class ContactSync_Service extends IntentService { 

public ContactSync_Service() { 
    super("intent service"); 

} 

@Override 
protected void onHandleIntent(Intent intent) { 

    MyContentObserver contentObserver = new MyContentObserver();

      .getContentResolver() 
      .registerContentObserver(ContactsContract.Contacts.CONTENT_URI, 
        true, contentObserver); 
} 

@Override 
public void onCreate() { 
    // TODO Auto-generated method stub 
    super.onCreate(); 

} 

class MyContentObserver extends ContentObserver { 

    public MyContentObserver() { 
     super(null); 
    } 

//whenever a contact is add,modified,delete this method will get called 
    @Override 
    public void onChange(boolean selfChange) { 
     Log.e("changes", "changes"); 

     syncDatabase();
