Android不承认org.apache.commons.validator [英] android doesn't recognize org.apache.commons.validator

问题描述

我要检查URL地址的有效性，所以经过一番研究，我发现使用apache.commons.validator.UrlValidator类是一个很好的解决方案，要做到这一点，这是code的例子：

I want to check the validity of a URL address, so after some research, i find that using apache.commons.validator.UrlValidator class is a good solution to do that, this is an example of code :

    import org.apache.commons.validator.UrlValidator;

    public class ValidateUrlExample{

public static void main(String[] args) {

    UrlValidator urlValidator = new UrlValidator();

    //valid URL
    if (urlValidator.isValid("http://www.mkyong.com")) {
       System.out.println("url is valid");
    } else {
       System.out.println("url is invalid");
    }

    //invalid URL
    if (urlValidator.isValid("http://invalidURL^$&%$&^")) {
        System.out.println("url is valid");
    } else {
        System.out.println("url is invalid");
    }

}
}

但是Android不承认阶级org.apache.commons.validator
有谁知道我应该怎么做才能解决这个问题？

but android doesn't recognize the class "org.apache.commons.validator" Does anyone know what should I do to fix that ?

在此先感谢

推荐答案

如果您仍然想使用Apache Commons验证库，那么你只需要下载的图书馆并与您的应用程序打包。

If you still want to use the apache commons validator library, then you just need to download the library and package it with your app.
