我正在为我的应用程序制作通知栏，虽然它在htc sensation上运行良好，但在htc desire上不起作用。有人能告诉我为什么吗，这是我的代码：

  1. private void startNotification() {
  3. remoteViews = new RemoteViews(getPackageName(),
  4.                     R.layout.simple_notification);
  5.         NotificationCompat.Builder builder = new NotificationCompat.Builder(
  6.                 this).setSmallIcon(R.drawable.ic_launcher).setContent(
  7.                 remoteViews);
  9.         NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  10.         Notification notification = builder.setContentTitle("Flashlight")
  11.                 .setContentText("Lighten your world!!!").build();
  12.         notificationManager.notify(1, notification);
  14.         // the intent that is started when the notification is clicked (works)
  15.         Intent notificationIntent = new Intent(this, FlashLight.class);
  16.         PendingIntent pendingMainNotificationIntent = PendingIntent
  17.                 .getActivity(this, 0, notificationIntent, 0);
  19.         notification.contentIntent = pendingMainNotificationIntent;
  20.         notification.flags |= Notification.FLAG_NO_CLEAR;
  22.         // this is the intent that is supposed to be called when
  23.         // the ON/OFF buttons are clicked
  24.         Intent switchIntent = new Intent(this, switchOffButtonListener.class);
  25.         PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0,
  26.                 switchIntent, 0);
  28.         remoteViews.setOnClickPendingIntent(R.id.closeOnFlash,
  29.                 pendingSwitchIntent);
  31.         Intent switchOnIntent = new Intent(this, switchOnButtonListener.class);
  32.         PendingIntent pendingSwitchOnIntent = PendingIntent.getBroadcast(this,
  33.                 0, switchOnIntent, 0);
  35.         remoteViews.setOnClickPendingIntent(R.id.onCloseFlash,
  36.                 pendingSwitchOnIntent);
  38.         notificationManager.notify(1, notification);
  39.     }

我自己想清楚在旧的android版本中，你的通知必须有一个内容意图，这样当用户点击你的通知时，就会发生一些事情。
这是运行代码在这里必须添加setcontentintent（）；

  1. private void startNotification() {
  3.     // In older android versions, your Notification has to have a content
  4.     // Intent, so that when the user clicks your Notification, something
  5.     // happens default functionality
  6.     Intent intent = new Intent(this, FlashLight.class);
  7.     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  8.     PendingIntent pend = PendingIntent.getActivity(this, 0, intent,
  9.             PendingIntent.FLAG_UPDATE_CURRENT);
  11.     // checking the device has flash or not
  13.     RemoteViews remoteViews;
  14.     if (!hasFlash) {
  15.         remoteViews = new RemoteViews(getPackageName(),
  16.                 R.layout.simple_notification);
  17.     } else {
  18.         remoteViews = new RemoteViews(getPackageName(),
  19.                 R.layout.mynotification);
  20.     }
  21.     NotificationCompat.Builder builder = new NotificationCompat.Builder(
  22.             this).setSmallIcon(R.drawable.ic_launcher)
  23.             .setContent(remoteViews).setContentIntent(pend);
  25.     NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  26.     Notification notification = builder.setContentTitle("Flashlight")
  27.             .setContentText("Lighten your world!!!").build();
  28.     notificationManager.notify(1, notification);
  30.     // the intent that is started when the notification is clicked (works)
  31.     Intent notificationIntent = new Intent(this, FlashLight.class);
  32.     PendingIntent pendingMainNotificationIntent = PendingIntent
  33.             .getActivity(this, 0, notificationIntent, 0);
  35.     notification.contentIntent = pendingMainNotificationIntent;
  36.     notification.flags |= Notification.FLAG_NO_CLEAR;
  38.     // this is the intent that is supposed to be called when
  39.     // the ON/OFF buttons are clicked
  40.     Intent switchIntent = new Intent(this, switchOffButtonListener.class);
  41.     PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0,
  42.             switchIntent, 0);
  44.     remoteViews.setOnClickPendingIntent(R.id.closeOnFlash,
  45.             pendingSwitchIntent);
  47.     Intent switchOnIntent = new Intent(this, switchOnButtonListener.class);
  48.     PendingIntent pendingSwitchOnIntent = PendingIntent.getBroadcast(this,
  49.             0, switchOnIntent, 0);
  51.     remoteViews.setOnClickPendingIntent(R.id.onCloseFlash,
  52.             pendingSwitchOnIntent);
  54.     notificationManager.notify(1, notification);
  55. }
