Get the specific value from the last part of a String in Android

I wanted to get the value from the last part of a String, here's my example String

String str="www.mywebsite.com?id=0001&user=myname"

I like to get the word myname from that String, All examples that I'm seeing is like this

String getUser = str.substring(str.length() - 6);

but user value length changes every transaction so I can't fix that to any value. Can anyone please help me in how I will be able to get the user value from that String. Thanks.

String str="www.mywebsite.com?id=0001&user=myname";
String user = getQueryParamValue(str);

public static final String getQueryParam(String url) {
    List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), "UTF-8");

    for (NameValuePair param : params){
        if("user".equalsIgnoreCase(param.getName())) {
            return param.getValue();
        }
    }
    return null;
}

If your string is going to be a uri, you can use Uri's getQueryParameter:

String str="www.mywebsite.com?id=0001&user=myname";
Uri uri = Uri.parse(str);
return uri.getQueryParameter("user");

Try this 

String foo = "www.mywebsite.com?id=0001&user=myname";
String[] split = foo.split("=");
String name = split[split.length-1];

with String.split(), you can split strings with a delimiter and put the values in an array. It is similar to PHPs' explode method.

String getUser=str.subString(str.lastIndexOf("=")+1,Str.length());

Will return myname.
