内容观察者被调用，即使联系人没有改变 [英] Content observer is being called even if the Contacts are not changed

问题描述

我现在面临一个问题，奇怪的是，我现在用的是 ContentObserver 赶在联系人的变化，但问题是，的onchange（）方法被调用，即使我没有做任何更改。这里是我的code：

I am facing a problem that is strange, i am using the ContentObserverto catch the changes in the contacts, but the problem is that the onchange() method is called even if i am not making any changes. Here is my code :

getContentResolver().registerContentObserver(ContactsContract.Contacts.CONTENT_URI, true, new MyCOntentObserver());

public class MyCOntentObserver extends ContentObserver{
        public MyCOntentObserver() {
            super(null);
        }
        @Override
        public void onChange(boolean selfChange) {
        super.onChange(selfChange);
            Log.e("","~~~~~~"+selfChange);
        }  

        @Override
        public boolean deliverSelfNotifications() {
            Log.e("","~~~~~~ Change");
            return true;
        }
    }

任何一个能帮忙吗？结果
在此先感谢

any one can help?
thanks in advance

推荐答案

的 registerContentObserver 方法接受一个布尔值 notifyForDescendents 变量，你设置为true。也许设置为false？

The registerContentObserver method accepts a boolean notifyForDescendents variable, which you're setting to true. Maybe set that to false?

否则也许有些后台任务与您的观察者搞乱。 ：）

Otherwise maybe some background task is messing with your observer. :)
