Question

NotificationManager notificationManager = (NotificationManager) CONTEXT
                            .getSystemService(Context.NOTIFICATION_SERVICE);

Notification notification = new Notification(R.drawable.ic_launcher,                                    "New Messege", System.currentTimeMillis());                         

// Hide the notification after its selected

notification.flags |= Notification.FLAG_AUTO_CANCEL;

// Opening application on notification select

Intent intent = new Intent(CONTEXT, Welcome.class);

//intent.putExtra("payload", payload);


PendingIntent pendingIntent = PendingIntent.getActivity(CONTEXT, 0,intent, 0);

notification.setLatestEventInfo(CONTEXT, "Message","message", pendingIntent);

notification.flags |= Notification.FLAG_AUTO_CANCEL;

notificationManager.notify(0, notification);

我的问题是，当我点击通知中心的通知时，它无法启动我的应用。基本上，点击我的通知后没有任何反应！我已经尝试了很多解决方案但没有任何反应。

我在应用程序运行时遇到另一个问题（不在后台）它还会在通知栏中显示通知。请指导我。提前完成。

你有没有尝试过：

notification.setContentIntent(pendingIntent);

看看这个精彩的教程，在通知上解释了很多这个： http://www.vogella.com/tutorials/AndroidNotifications/article.html

希望此代码snippnet可以帮助您：

    @SuppressLint("NewApi")
    public void shownotification(Context context)
    {
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!")
               // .setDeleteIntent(getDeleteIntent())
               // .setContentIntent(PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0))
                .setOngoing(true);

        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(getApplicationContext(), MYDEMOACTIVITY.class);
            // 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(context);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(MYDEMOACTIVITY.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        // mId allows you to update the notification later on.
        mNotificationManager.notify(mId, mBuilder.build());
    }

解释：此处中间是我的应用的通知ID eg:final int mId = 0;，MYDEMOACTIVITY.class是我要点击通知后要启动的另一项活动。

单击“通知”后，应用程序无法打开
