Android Wear开发可能用到的Android通知栏监听（仅适用4.3及以上）

1.在Manifest中加入以下内容

        <service
            android:name="com.example.watch.NotificationCollectorService"
            android:label="通知栏监听"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
            <intent-filter>
                <action android:name="android.service.notification.NotificationListenerService" />
            </intent-filter>
        </service>

其中com.example.watch.NotificationCollectorService为自定义的服务名

2.继承NotificationListenerService

public class NotificationCollectorService extends NotificationListenerService {
	@Override
	public void onNotificationPosted(StatusBarNotification sbn) {
		Log.i("123", "open" + "-----" + sbn.toString());
	}

	@Override
	public void onNotificationRemoved(StatusBarNotification sbn) {
		Log.i("123", "shut" + "-----" + sbn.toString());
	}
}

3.让用户在手机中勾选我们的APP(首次使用要求用户勾选，否则service无效)

Intent intent = new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS");
startActivity(intent);
