BroadcastReceiver 用于在收藏夹/注视中添加或删除联系人时收听

Question

在收藏夹/已加星标的联系人列表中添加/删除联系人时，是否有办法收听/处理。

我已经检查了onChange()。但它不处理收藏夹/加星标设置。

有一个默认的联系观察者..希望对你有帮助

public class MyCOntentObserver extends ContentObserver {
        public MyCOntentObserver() {
            super(null);
        }

        @Override
        public void onChange(boolean selfChange) {
            super.onChange(selfChange);
            final int currentCount = getContactCount();

            // Get count from your sqlite database
            int mContactCount = getContactOWNCount();

            if (currentCount < mContactCount) {
                // DELETE HAPPEN.
                Log.e("Status", "Deletion");
                //contactDBOperaion.SyncContacts(1);
            } else if (currentCount == mContactCount) {
                // UPDATE HAPPEN.
                //  contactDBOperaion.SyncContacts(0);
            } else {
                // INSERT HAPPEN.
                Log.e("Status", "Insertion");
                // contactDBOperaion.SyncContacts(2);
            }
            Log.e("", "~~~~~~" + selfChange);
        }

        @Override
        public boolean deliverSelfNotifications() {
            return true;
        }
    }
