单击通知未开始预期活动? [英] Clicking on Notification is not starting intended activity?

问题描述

我在我的应用程序中使用 GCM，并且在收到 GCM 消息时也使用 NotificationManager 创建通知.到目前为止，一切正常，GCM 消息在通知区域中正确显示，但是当我单击通知时，它应该启动我的应用程序的活动将显示未发生的消息详细信息.每次我点击通知时，它都不会启动任何活动，并且保持原样.我创建通知的代码是:

I am using GCM in my application and also using NotificationManager to Create a Notification whenever GCM message is received.Till now everything is working perfectly and GCM message is showing correctly in Notification area, but when I click on the notification it should start an activity of my application which will display the message detail which is not happening. Every-time I click on notification it does not start any activity and it remains as is.My code for creating Notification is :

private void sendNotification(String msg) {
        SharedPreferences prefs = getSharedPreferences(
                DataAccessServer.PREFS_NAME, MODE_PRIVATE);
        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Intent intent = new Intent(this, WarningDetails.class);
        Bundle bundle = new Bundle();
        bundle.putString("warning", msg);
        bundle.putInt("warningId", NOTIFICATION_ID);
        intent.putExtras(bundle);
        // The stack builder object will contain an artificial back stack for
        // the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(WarningDetails.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(intent);

        PendingIntent contentIntent = stackBuilder.getPendingIntent(0,
                PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.weather_alert_notification)
                .setContentTitle("Weather Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg);
        String selectedSound = prefs.getString("selectedSound", "");
        if (!selectedSound.equals("")) {
            Uri alarmSound = Uri.parse(selectedSound);
            mBuilder.setSound(alarmSound);

        } else {
            Uri alarmSound = RingtoneManager
                    .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            mBuilder.setSound(alarmSound);
        }

        if (prefs.getBoolean("isVibrateOn", false)) {
            long[] pattern = { 500, 500, 500, 500, 500, 500, 500, 500, 500 };
            mBuilder.setVibrate(pattern);
        }

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

我更新了我的代码以支持 Preserving Navigation when Start an Activity 就像它发生在使用 Android 开发者网站的 Gmail 应用程序中一样，从那时起它就停止工作了.有人请指导我我遗漏了什么或在做什么这段代码错了.

I updated my code to support Preserving Navigation when Starting an Activity just like it happens in Gmail application using the Android developers website since then it stopped working.Someone Please guide me what I am missing or doing wrong in this code.

推荐答案

我的问题解决了我只需要添加 PendingIntent.FLAG_ONE_SHOT 标志，所以我替换了:

My problem got solved I just have to add PendingIntent.FLAG_ONE_SHOT flag as well , so I replaced :

PendingIntent contentIntent = stackBuilder
                .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

到

PendingIntent contentIntent = stackBuilder
                .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT
                        | PendingIntent.FLAG_ONE_SHOT);
