【移动应用开发技术】Android如何实现仿QQ微信实时监测网络状态

这篇文章将为大家详细讲解有关Android如何实现仿QQ微信实时监测网络状态，在下觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。思路判断网络状态（写个工具类NetUtil）写个类继承BroadcastReceiver（不要忘记在清单文件中注册）需要在清单文件中添加权限<uses-permission

android:name="android.permission.ACCESS_NETWORK_STATE">

</uses-permission>回调接口（NetEvevt）BaseActivity实现这个接口直接上代码NetUtilimport
