问题 This question already has answers here : How to update RecyclerView Adapter Data? (13 answers) Closed yesterday . I have a RecyclerView horizontal image slider at the bottom of a fragment.

问题 Given these classes: @Value private static class Message { private final String type; private final MyType message; } @Value public class MyType { private final String foo; } Jackson will produce: { "Type" : "Test", "Message" : {"foo" : "bar"} } Is there some type of annotation or instruction I can give to Jackson to ask it to serialize the nested complex type as a string, e.g. the desired JSON would be: { "Type" : "Test", "Message" : "{\"foo\" : \"bar\"}" } I tried both of these annotations

问题 I'm trying to formalize each integer as an equivalence class of pairs of natural numbers, where the first component is the positive part, and the second component is the negative part. Definition integer : Type := prod nat nat. I want to define a normalization function where positives and negatives cancel as much as possible. Fixpoint normalize (i : integer) : integer := let (a, b) := i in match a with | 0 => (0, b) | S a' => match b with | 0 => (S a', 0) | S b' => normalize (a', b') end end.
