问题描述

我创建了一个活动，该活动在发生通知时会刷新，但是我面临的一个问题是，当通知到来时，它会继续发送无尽的相同通知。之前它运行良好，但是我做了一些更改，并且做到了。请帮我。我在其中附加我的代码。

I have created a activity which got refreshes while a notification occurs but I am facing one problem which is that when a notification came it continues to send endless same notification. Earlier it was working fine but I made some changes and this had done. Please help me. I am attaching my code with it.

GCM IntentService类的代码

         @Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    String msgg = intent.getStringExtra("message");

     final ResultReceiver receiver = intent.getParcelableExtra("receiver");
    Bundle bundle = new Bundle();
    if (!extras.isEmpty()) {

        if (GoogleCloudMessaging.
                MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {

            sendNotification(this, msgg);


        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_DELETED.equals(messageType)) {

            sendNotification(this, msg);
            updateMyActivity(this,msgg);
            bundle.putString("result", msg);
            receiver.send(STATUS_FINISHED, bundle);

        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            updateMyActivity(this,msgg);
            sendNotification(this, msg);



        }


}

发送通知代码

 private void sendNotification(Context context, String message) {

    Intent resultIntent;

    int icon = R.mipmap.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationCompat.Builder nBuilder;
    Uri alarmSound = RingtoneManager
            .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


    NotificationCompat.BigPictureStyle notiStyle = new
            NotificationCompat.BigPictureStyle();
    notiStyle.setBigContentTitle("afewtaps");
    notiStyle.setSummaryText(message);


    nBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(icon)
            .setContentTitle("afewtaps")
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setLights(Color.BLUE, 500, 500).setContentText(message)
            .setAutoCancel(true).setTicker("Notification from afewtaps")
            .setSound(alarmSound);



    resultIntent = new Intent(context,
            LoginActivity.class);
    resultIntent.putExtra("message", message);

    resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    // Show the max number of notifications here
    if (notify_no < 9) {
        notify_no = notify_no + 1;
    } else {
        notify_no = 0;
    }
    nBuilder.setContentIntent(resultPendingIntent);

    NotificationManager nNotifyMgr = (NotificationManager) context
            .getSystemService(context.NOTIFICATION_SERVICE);



    nNotifyMgr.notify(notify_no + 2, nBuilder.build());


}

发送消息进行广播

    // This function will create an intent. This intent must take as parameter the "unique_name" that you registered your activity with
static void updateMyActivity(Context context, String message) {

    Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

    //put whatever data you want to send, if any
    intent.putExtra("message", message);

    //send broadcast
    context.sendBroadcast(intent);
}

这将结束意图类的代码。

现在我的活动代码

         @Override
public void onResume() {
    super.onResume();
   // connectToDatabase();
    getActivity().registerReceiver(mMessageReceiver, new IntentFilter("com.google.android.c2dm.intent.RECEIVE"));
}

//Must unregister onPause()
@Override
public void onPause() {
    super.onPause();
    getActivity().unregisterReceiver(mMessageReceiver);
}


//This is the handler that will manager to process the broadcast intent
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        // Extract data included in the Intent
        String message = intent.getStringExtra("message");

        //do other stuff here

        connectToDatabase();


    }
};

推荐答案

好的。因此，您的代码正在发生的事情是，您正在向广播接收器发送广播，并强制再次调用 onHandleIntent ，结果调用了updateActivity方法，该方法再次广播和循环不断进行。

Okay. So what is happening with your code is that you are sending a broadcast to your Receiver as well forcing the onHandleIntent to be invoked again, which in result calls the updateActivity method, which again broadcasts and loop continues endlessly.

在您的 updateMyActivity 方法中，请更改以下内容：

In your updateMyActivity method, please change this:

Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

到

Intent intent = new Intent("myMessage");

罪魁祸首是

com.google.android.c2dm.intent.RECEIVE

此外，在您的活动的 onResume 方法中，请更改 TAG 到 myMessage ：

Also, in your onResume method of the activity, please change the TAG to myMessage:

getActivity().registerReceiver(mMessageReceiver, new IntentFilter("myMessage"))
