Question

我正在尝试在Android上启用Wifi Zone（Wifi AP）（Jelly Bean 4.2.2），但我找不到办法。

我实际上可以启用/禁用wifi连接，但不能启用AP（共享Wifi）。

我正在使用Xamarin（C＃），但它在SDK上使用相同的API，因此java中的任何示例也都可以使用（几乎没有编辑）。

谢谢大家，祝你有个美好的一天。

我找到了一段时间前做的事，就在这里：

//Enable / Disable Wifi AP
public void SetHotSpot(Boolean On)  {

    WifiManager wifiManager = (WifiManager) context.GetSystemService(Context.WifiService);
    Method[] wmMethods = wifiManager.Class.GetDeclaredMethods();
    WifiConfiguration wifiConfig = new WifiConfiguration();
    Boolean enabled = false;

    //Verify The Wifi AP State And Get The Actual Config
    foreach (Method m in wmMethods) {

        //Get Wifi AP State
        if (m.Name.Equals ("isWifiApEnabled")) {

            enabled = (Boolean) m.Invoke (wifiManager);
        }

        //Get Actual Config And Change Password
        if (m.Name.Equals ("getWifiApConfiguration")) {

            try {

                wifiConfig = (WifiConfiguration)m.Invoke (wifiManager, null);
                Random rand = new Random ();

                wifiConfig.Ssid = "Wifi Name " + rand.Next(0, 10) + rand.Next(0, 10) + rand.Next(0, 10) + rand.Next(0, 10);
                wifiConfig.PreSharedKey = "Password" + rand.Next(0, 10) + rand.Next(0, 10);
            } catch (Exception ex) {

                Log.Info (Activity, "Fail Setting New Wifi Name And Password\n\n" + ex);
            }
        }
    }

    //If Received Flag Is TRUE And Wifi AP Is Disabled, Enable It
    if (On && !enabled) {

        //Start Wifi AP With New Configuration
        foreach (Method m in wmMethods) {

            if (m.Name.Equals ("setWifiApEnabled")) {

                try {

                    m.Invoke (wifiManager, wifiConfig, true);
                } catch (Exception ex) {

                    Log.Info (Activity, "Fail Enabling Wifi AP\n\n" + ex);
                }
                break;
            }
        }
    }

    //If Received Flag Is FALSE And Wifi AP Is Enabled, Disable It
    else if (!On && enabled) {

        foreach(Method method in wmMethods) {

            if(method.Name.Equals("setWifiApEnabled"))  {

                try {

                    method.Invoke(wifiManager, wifiConfig, false);
                } catch (Exception ex) {

                    Log.Info (Activity, "Fail Disabling Wifi AP\n\n" + ex);
                }
                break;
            }
        }
    }
}

如何在Android上使用Xamarin（C＃）启用Wifi区域（Wifi AP）？
