本文介绍了一个用于检测设备网络状态的实用工具类，包括判断是否为Wi-Fi或移动数据网络，并在非Wi-Fi环境下提示用户的功能。此外，还提供了一个用于设置网络连接状态的方法。

public static boolean isWiFi(Context context){
    ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = manager.getActiveNetworkInfo();
    if (info!=null&&info.getType()==manager.TYPE_WIFI){
        return true;
    }
    return false;
}
//判断是不是流量
public static boolean isMobile(Context context){
    ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = manager.getActiveNetworkInfo();
    if (info!=null&&info.getType()==manager.TYPE_MOBILE){
        return true;
    }
    return false;
}
