如何使RemoteView失效

Question

我正在進行自定義通知，並且在接收者中意圖更改通知本身的佈局中的元素中的文本。當我更新通知時沒有任何反應。意圖正在傳遞給接收者，我檢查了日誌。使通知的活動和接收者是獨立的類。有任何想法嗎？我知道那個AppWidgetProvider對於widget的效果很好，但是在這種情況下沒有AppWidgetProvider，這是一個普通的通知。有沒有其他的方法來使RemoteView無效？

//Receiver.onReceive() method 
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.notification_layout); 

//make dataString 
views.setTextViewText(R.id.n_track_name, dataString); 

//while searching i figured out this is something that should update notification 
NotificationManager mNotificationManager = (NotificationManager)act.getSystemService(Activity.NOTIFICATION_SERVICE); 
mNotificationManager.notify(1, act.notification); 

這是代碼，這使得通知在其他活動第一次：

Notification notification = new Notification(icon, "Music Player", when); 
NotificationManager mNotificationManager = (NotificationManager)MusicPlayerActivity.currentActivity.getSystemService(NOTIFICATION_SERVICE); 
RemoteViews contentView = new RemoteViews(act.getPackageName(), R.layout.notification_layout); 

//make pending intent on button 
Intent intent = new Intent(act, NotificationReceiver.class); 
intent.setAction(NotificationReceiver.ACTION_NOTIFICATION_NEXT); 
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(act, 0, intent, 0); 
contentView.setOnClickPendingIntent(R.id.n_btnNext, actionPendingIntent); 

//make other intents 
//show notification 
mNotificationManager.notify(1, notification);

如果任何人有同樣的問題，這裏是解決方案：

act.notification.contentView = views; 

此代碼必須是放置接收者代碼。已更改RemoteView必須分配給開始通知，並且只有Notificationmanager實際上可以用新的替換舊視圖。
