使通知图标出现在启动/耳机插件上

我想让它在插入耳机时出现一个通知图标。我已经做到了，当手机打开时，它会启动 MainActivity 类，该类在 OnCreate 方法中包含通知图标的代码，因此它会自动启动。问题是它启动了整个活动和应用程序，这是我不想要的。我只是想让图标出现。我该怎么办呢？谢谢你！

public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Intent myIntent = new Intent(context, MainActivity.class);
    myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(myIntent);
}

上面的代码在启动时启动 MainActivity。

通知图标代码

    //Notification Icon Starts
    NotificationManager nm=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification=new Notification(R.drawable.icon_notification, "Icon Notification", System.currentTimeMillis());
    Context context=MainActivity.this;
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), Notification.FLAG_ONGOING_EVENT);        
    notification.flags = Notification.FLAG_ONGOING_EVENT;
    notification.setLatestEventInfo(this, "Notification Icon", "Touch for more options", contentIntent);
    Intent intent=new Intent(context,MainActivity.class);
    PendingIntent  pending=PendingIntent.getActivity(context, 0, intent, 0);
    nm.notify(0, notification);
    //Notification Icon Ends

正如我在你的最后一个问题 https://stackoverflow.com/questions/19338612/doing-something-if-it-detects-that-headphones-are-plugged-in, add a <receiver>在你的清单中监听ACTION_HEADSET_PLUG播送。这文档 http://developer.android.com/reference/android/content/Intent.html#ACTION_HEADSET_PLUG shows Intent您可以使用附加功能来确定耳机是否已插入（state), etc.
