在广播接收器中获取通知

Question

我在清单文件中添加了一些像AACTION_POWER_CONNECTED的itent，我想在充电器连接时获得通知。这是我的代码。

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(); 

    } 
} 

我每次连接充电器时都收到Toast，但没有收到通知。由于我在Android中是全新的，我不知道如何实现这一点。

试试这个代码：

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()); 
    } 
} 

其实你创建的通知对象，但从来没有发射吧:) 所以，你只需用notify()打电话剩余。
