Android URL中参数的获取、拼接及修改

1、获取参数

Uri uri = Uri.parse(url);String type = uri.getQueryParameter("key");

2、拼接

Uri.Builder builder = Uri.parse(url).buildUpon();builder.appendQueryParameter("key", value);

3、修改

public static String replace(String url, String key, String value) {    if (!TextUtils.isEmpty(url) && !TextUtils.isEmpty(key)) {        url = url.replaceAll("(" + key + "=[^&]*)", key + "=" + value);    }    return url;}
