You can use the Uri class in Android to do this; https://developer.android.com/reference/android/net/Uri.html
您可以使用 Android 中的 Uri 类来执行此操作； https://developer.android.com/reference/android/net/Uri.html
Uri uri = Uri.parse("http://www.chalklit.in/post.html?chapter=V-Maths-Addition%20&%20Subtraction&post=394");
String server = uri.getAuthority();
String path = uri.getPath();
String protocol = uri.getScheme();
Set<String> args = uri.getQueryParameterNames();
Then you can even get a specific element from the query parameters as such;
然后您甚至可以从查询参数中获取特定元素；
String chapter = uri.getQueryParameter("chapter"); //will return "V-Maths-Addition "
