将服务绑定到 BroadcastReceiver [英] Bind Service to BroadcastReceiver

问题描述

我有一些 Service 类，用于注册多个警报.

I have some Service class, which registers multiple alarms.

在我的 BroadcastReceiver 类中，我希望 onReceive() 方法调用 Service 类的某些方法.

In my BroadcastReceiver class, I want the onReceive() method to call some method of the Service class.

但是，我不知道如何将它们绑定在一起.我试图让 BroadcastReceiver 成为一个内部类，但后来我得到了更多的错误并且根本无法触发警报.

However, I don't see how I can bind them together. I tried to make the BroadcastReceiver an inner class, but then I got more errors and couldn't fire the alarm at all.

谢谢

推荐答案

看http://developer.android.com/reference/android/content/BroadcastReceiver.html 生命周期.BroadcastReceiver 仅用于处理消息.这意味着它的寿命很短，蚂蚁也是无国籍的.所以你不能绑定任何东西.

Look at http://developer.android.com/reference/android/content/BroadcastReceiver.html life cycle. BroadcastReceiver is created only for handling a message. It means that it's life is very short, ant it is also stateless. So you cannot bind anything to it.

无论如何你可以尝试启动一个service表单onReceive(Context context, Intent intent) BroadcastReceiver的方法，像这样:

Anyway you can try to start a service form onReceive(Context context, Intent intent) method of BroadcastReceiver, like this:

    public void onReceive(Context context, Intent intent) {
        Intent intent2 = new Intent(context, GCMService.class);
        intent2.putExtras(intent);
        context.startService(intent2);
}

然后 a=服务应该处理广播消息.

Then a=the service should handle a broadcast message.
