Android PendingIntent for foreGround服务

我仍然在前台开始服务时感到十分困惑。Android PendingIntent for foreGround服务

当前：我有一个活动，在后台启动一个服务来执行传感器数据+ GPS数据的统计。它不断被杀死，所以我开始在前台。工作正常。但是，当我触摸状态栏中的通知图标时，它似乎开始一个新的活动（我在待定意图中声明）。

所以简而言之，我仍然对整个事情感到困惑。我想要一个活动在前台启动一项服务，并且当您单击通知栏时，它会将启动服务的现有活动带到前台。

这里的活动（当前设置的PendingIntent为null）中的一些代码：

private ServiceConnection mConnection = new ServiceConnection() { 
    public void onServiceConnected(ComponentName className, IBinder service) { 
     // This is called when the connection with the service has been 
     // established, giving us the service object we can use to 
     // interact with the service. Because we have bound to a explicit 
     // service that we know is running in our own process, we can 
     // cast its IBinder to a concrete class and directly access it. 

     cycleDataService = ((CycleDataProService.LocalBinder) service) 
       .getService(); 
     //Todo the notification bullshaite here... 
     String ns = Context.NOTIFICATION_SERVICE; 
     NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); 
     int icon = R.drawable.icon; 
     CharSequence tickerText = "Hello"; 
     long when = System.currentTimeMillis(); 
     Notification notification = new Notification(icon, tickerText, when); 
     Context context = getApplicationContext(); 
     CharSequence contentTitle = "My notification"; 
     CharSequence contentText = "Hello World!";   
     //Intent notificationIntent = new Intent(cycleDataService, CycleDataProService.class); 
     //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, myOwnIntent, PendingIntent.FLAG_UPDATE_CURRENT); 
     PendingIntent pi = PendingIntent.getActivity(context, 0, null, 0); 

     //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, , 0); 
     notification.setLatestEventInfo(context, contentTitle, contentText, pi); 
     mNotificationManager.notify(HELLO_ID, notification); 
     cycleDataService.startForeground(HELLO_ID, notification); 
     /*cycleDataService.startService(new Intent(cycleDataService, 
       CycleDataProService.class));*/ 
     serviceIsRunning = true; 
     // Tell the user about this for our demo. 
     // Toast.makeText(Binding.this, R.string.local_service_connected, 
     // Toast.LENGTH_SHORT).show(); 
    }

用这样的方式：

Intent notificationIntent = new Intent(context, YourActivity.class); 
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); 
    notification.contentIntent = contentIntent; 
    notification.setLatestEventInfo(context, "title", null, contentIntent);

使用FLAG_ACTIVITY_SINGLE_TOP如果你希望你的活动继续下去，而不是重新启动。

Intent notificationIntent = new Intent(context, YourActivity.class); 
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); 
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); 
notification.contentIntent = contentIntent; 
notification.setLatestEventInfo(context, "title", null, contentIntent);
