how to validate a URL / website name in EditText in Android?

Question

I want to take input, a URL or just a website name like, www.google.com from EditText in Android and on user click on the Button to submit

Answer 1

Use this regex on your website validation

String WebUrl = "^((ftp|http|https):\\/\\/)?(www.)?(?!.*(ftp|http|https|www.))[a-zA-Z0-9_-]+(\\.[a-zA-Z]+)+((\\/)[\\w#]+)*(\\/\\w+\\?[a-zA-Z0-9_]+=\\w+(&[a-zA-Z0-9_]+=\\w+)*)?$";


//TODO for website validation

private boolean isValidate() 
{

        String website = txtWebsite.getText().toString().trim();
        if (website.trim().length() > 0) {
            if (!website.matches(WebUrl)) {
                //validation msg
                return false;
            }
        }
        return true;

}
