Android：我正在尝试在安装软件包后取消通知栏中的通知.

我正在做的是以下内容：

public class MyBroadcastReceiver extends BroadcastReceiver {

private static final String TAG = "MyBroadcastReceiver";

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {

Uri data = intent.getData();

//some code goes here

//get the id of the notification to cancel in some way

notificationhelper._completeNotificationManager.cancel(id);

}

}

}

哪里

public class notificationhelper {

public static NotificationManager _completeNotificationManager = null;

public void complete() {

if (_completeNotificationManager == null)

_completeNotificationManager = (NotificationManager) _context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = new Notification(

R.drawable.notification,

_context.getString(R.string.notification),

System.currentTimeMillis());

notification.flags |= Notification.FLAG_AUTO_CANCEL;

notification.flags |= Notification.FLAG_NO_CLEAR;

_completeNotificationManager.notify(TEXT, id, notification);

}

}

但是notificationhelper._completeNotificationManager.cancel(id)不起作用.我试着使用notificationhelper._completeNotificationManager.cancelAll();它的工作原理.我做错了什么？
