如何以编程方式处理 WiFi 到移动网络的切换？

现在，我的应用程序可以与 WiFi 配合使用，但是当我要使用移动提供商网络时，我的应用程序无法运行。我维护了一项检查网络的后台服务，但我不知道如何处理网络切换 WiFi 到移动设备和移动设备到 WiFi？我不知道如何处理 WiFi 到移动网络的切换，因为 WiFi 已经启用并且我不在 WiFi 覆盖区域；在这种情况下，我想自动切换到移动网络，反之亦然。我的方法如下，但不起作用：

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }

我已经阅读了很多帖子，但仍然不明白。谁能给我任何想法或网址，我可以在其中获得相同的实施方法？

提前致谢。

Right now, I am having application which works with WiFi, but while I am going to mobile providers network my application does not working. I have maintained one background service which checks for network, but im not getting how to handle network switch WiFi to Mobile and Mobile to WiFi? I am not getting how to handle WiFi to mobile network switch because already WiFi is enabled and I am not in WiFi coverage area; in this situation I want to get switched to mobile network automatically and vice-versa. My approach is as follows which is not working:

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }

Already I have read many posts over hear still not getting idea. Can anyone give me any idea or url where I can get same approach to implement?

Thanks in Advance.

我得到了解决方案：

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }

I got the solution:

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }
