如何通过从微调器中选择来启用 wifi。我会感谢你

Answer 1

将这段代码添加到你的监听器

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(true);

或切换行为

wifi.setWifiEnabled(!wifi.isWifiEnabled());

您可能需要向您的 list 添加一些权限

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

参见 WifiManager更多选项...

据我所知，热点功能没有 API。您将不得不使用反射来调用这些方法...
