即使联系人未更改, 内容观察者也会被调用
原标题:Content observer is being called even if the Contacts are not changed

我正面临一个奇怪的问题, 我正使用 Content观察员 来捕捉联系人的更改, 但问题是, 即使我不做任何更改, 也使用 conchange () 方法。 这是我的代码 :

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;
        }
    }

any one can help?
thanks in advance

registerContent观察员 方法接受一个布林 通知ForDescents 变量,您将设置该变量为真。 可能设置为假?

否则,也许有些背景任务正在搅乱您的观察者。 ) :
