When I turn on the wifi switch, the switch will automatically turn off.

Make sure you got this permissions

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

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

And create wifiManager every time

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

wifiManager.setWifiEnabled(true);
