我可以以编程方式检查 android 设备是否已激活网络共享?
我刚看了 WifiManager 课。WifiInfo 中的所有变量都显示与设备上关闭 WIFI 时相同的值。
Thnaks,最好的问候
尝试使用反射,如下所示:
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
Method[] wmMethods = wifi.getClass().getDeclaredMethods();
for(Method method: wmMethods){
if(method.getName().equals("isWifiApEnabled")) {
try {
method.invoke(wifi);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
(它返回一个Boolean
)
正如丹尼斯建议最好使用这个:
final Method method = manager.getClass().getDeclaredMethod("isWifiApEnabled");
method.setAccessible(true); //in the case of visibility change in future APIs
return (Boolean) method.invoke(manager);
(经理是WiFiManager
)
首先,您需要获取 WifiManager:
Context context = ...
final WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
然后:
public static boolean isSharingWiFi(final WifiManager manager)
{
try
{
final Method method = manager.getClass().getDeclaredMethod("isWifiApEnabled");
method.setAccessible(true); //in the case of visibility change in future APIs
return (Boolean) method.invoke(manager);
}
catch (final Throwable ignored)
{
}
return false;
}
您还需要在 AndroidManifest.xml 中请求权限:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
