    public interface NetStateChangeObserver {

        void onDisconnect();

        void onMobileConnect();

        void onWifiConnect();
    }
}

在需要注册的地方使用：

NetworkChange.registerReceiver(context, this)

NetworkChange.unRegisterReceiver(context)

重写三个方法

@Override
    public void onDisconnect() {//没有网络

    }

    @Override
    public void onMobileConnect() {//移动网络

    }

    @Override
    public void onWifiConnect() {//WIFI网络

    }
