Android 以编程方式打开/关闭 WiFi 热点
问题描述:
是否有 API 可以通过编程方式在 Android 上打开/关闭 WiFi 热点?
Is there an API to turn On/Off the WiFi HotSpot on Android programmatically?
我应该调用什么方法来打开/关闭它?
What methods should I call to turn it On/Off?
更新:有这个选项可以启用热点,只需打开/关闭 WiFi,但这对我来说不是一个好的解决方案.
UPDATE:There's this option to have the HotSpot enabled, and just turn On/Off the WiFi, but this is not a good solution for me.

警告 此方法在 5.0 后无法使用,这是一个相当过时的条目.
使用下面的类来更改/检查Wifi hotspot
设置:
Use the class below to change/check the Wifi hotspot
setting:
import android.content.*;
import android.net.wifi.*;
import java.lang.reflect.*;
public class ApManager {
//check whether wifi hotspot on or off
public static boolean isApOn(Context context) {
WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
try {
Method method = wifimanager.getClass().getDeclaredMethod("isWifiApEnabled");
method.setAccessible(true);
return (Boolean) method.invoke(wifimanager);
}
catch (Throwable ignored) {}
return false;
}
// toggle wifi hotspot on or off
public static boolean configApState(Context context) {
WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
WifiConfiguration wificonfiguration = null;
try {
// if WiFi is on, turn it off
if(isApOn(context)) {
wifimanager.setWifiEnabled(false);
}
Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
method.invoke(wifimanager, wificonfiguration, !isApOn(context));
return true;
}
catch (Exception e) {
e.printStackTrace();
}
return false;
}
} // end of class
您需要将以下权限添加到您的 AndroidMainfest:
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
从任何地方使用这个独立的 ApManager 类,如下所示:
ApManager.isApOn(YourActivity.this); // check Ap state :boolean
ApManager.configApState(YourActivity.this); // change Ap state :boolean
希望这对某人有帮助
