在廣播接收器中獲取通知

Question

我在清單文件中添加了一些像AACTION_POWER_CONNECTED的itent，我想在充電器連接時獲得通知。這是我的代碼。

public class AwesomeReceiver extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     Toast.makeText(context, "Inside onReceive", Toast.LENGTH_LONG).show(); 
     NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context); 
     mBuilder.setSmallIcon(R.drawable.ic_launcher); 
     mBuilder.setContentTitle("This is A Notification"); 
     mBuilder.build(); 

    } 
} 

我每次連接充電器時都收到Toast，但沒有收到通知。由於我在Android中是全新的，我不知道如何實現這一點。

試試這個代碼：

public class AwesomeReceiver extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     Toast.makeText(context, "Inside onReceive", Toast.LENGTH_LONG).show(); 
     NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context); 
     mBuilder.setSmallIcon(R.drawable.ic_launcher); 
     mBuilder.setContentTitle("This is A Notification"); 

     NotificationManager mNotificationManager = 
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
     mNotificationManager.notify(mId, mBuilder.build()); 
    } 
} 

其實你創建的通知對象，但從來沒有發射吧:) 所以，你只需用notify()打電話剩餘。
