开启热点服务端部分代码
public void startWifiHot() { btnServer.setEnabled(false); if (wifiManager.isWifiEnabled()) { wifiManager.setWifiEnabled(false); } Boolean b = wifimanageutils.stratWifiAp(mSSID, mPasswd,3); if (b) { serverThread = new WifiServerThread(context, testh); Toast.makeText(context, "server 端启动", 3000).show(); serverThread.start(); } else { btnServer.setEnabled(true); Toast.makeText(context, "server 端失败，请重试", 3000).show(); } }
WifiServerThread服务端线程

开启客户端部分代码
