Andoird WiFi Direct (P2P) 关于 BroadcastReceiver 类的问题

问题描述

我正在尝试开发 WiFi Direct 数据传输应用程序，this official help page 是我当前的信息来源。然而，这句话我没看懂-

For the class' constructor,you will use parameters for the wifip2pManager,wifip2pManager.Channel,and the activity that this broadcast receiver will be registered in.

他们谈论的 activity 是以下类中的私有成员 -

/**
* A broadcastReceiver that notifies of important Wi-Fi p2p events.
*/
public class WiFiDirectbroadcastReceiver extends broadcastReceiver {

   private wifip2pManager manager;
   private Channel channel;
   private MyWiFiActivity activity; // <-- THIS ONE

   public WiFiDirectbroadcastReceiver(wifip2pManager manager,Channel channel,MyWifiActivity activity) {
       super();
       this.manager = manager;
       this.channel = channel;
       this.activity = activity;
   }
}

当我尝试按原样实现类时，出现错误 Cannot resolve symbol MyWiFiActivity。

我应该包括那种类型的导入，还是取决于我以后需要做的其他事情？

解决方法

他们所指的活动是在与教程相关的 sample project 中创建的。它注册广播接收器并处理生命周期事件等。您应该更改对您选择在其中实现相应回调的任何类的引用。
