您需要使用手册中记录的 Intent myIntent = new Intent(context, DoSomething.class); PendingIntent pendingIntent = PendingIntent.getActivity( context, 0, myIntent, Intent.FLAG_ACTIVITY_NEW_TASK); myNotification = new NotificationCompat.Builder(context) .setContentTitle("Exercise of Notification!") .setContentText("Do Something...") .setTicker("Notification!") .setWhen(System.currentTimeMillis()) .setContentIntent(pendingIntent) .setDefaults(Notification.DEFAULT_SOUND) .setAutoCancel(true) .setSmallIcon(R.drawable.ic_launcher) .build(); notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(MY_NOTIFICATION_ID, myNotification); ：
