对于Android，网络状态始终为true.如何? [英] Network status is always true for android. How?

问题描述

我正在尝试在我的android应用程序中检查网络状态.

I'm trying to check the network status in my android application.

我有这样的代码:

public boolean isNetworkAvailable()
{
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

    if(networkInfo != null && networkInfo.isConnected())
        return true;

    return false;
}

当预期的网络可用时，此代码将返回true，但即使网络不可用，该代码也将重试true.

This code is returning true when network is available as expected but it is also returing true even in case of network not-available.

在两种情况下都只需将其返回的true放进去！

Simply put its returning true for both the cases!

我在代码中哪里出错了?

Where I'm making the mistake in the code?

请注意，我是在模拟器中运行该应用程序的.

Note that I run the app in my emulator.

谢谢.

推荐答案

尝试以下方法对我来说很棒.我希望它也会对您有所帮助.

Try out below method it works awesome for me. I hope it will help you also.

 public static boolean IsNetConnected()
{
    boolean NetConnected = false;
    try
    {
        ConnectivityManager connectivity =
        (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity == null)
        {
            NetConnected = false;
        }
        else
        {
            NetworkInfo[] info = connectivity.getAllNetworkInfo();
            if (info != null)
            {
                for (int i = 0; i < info.length; i++)
                {
                    if (info[i].getState() == NetworkInfo.State.CONNECTED)
                    {
                        NetConnected = true;
                    }
                }
            }
        }
    }
    catch (Exception e)
    {
        NetConnected = false;
    }
    return NetConnected;
}
