推荐答案

您需要在您的清单文件中的以下权限：

You need the following permissions in your manifest file:

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

然后你可以使用你的活动类以下内容：

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

使用下面的检查，如果它的启用与否

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()
