I need to turn off the WiFi a while after pressing the "Turn off the Screen" button. There is need for this app for my tablet because sometimes I just forget to turn off the WiFi and this discharges the battery very fast. It lives 10x+ times less than I would without WiFi. Is there any solution available as .apk? Can I track when screen turned off and 5 min elapsed? Can I programatically turn off WiFi on Android device? How?

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()
