Gson how to get serialized name

Question

When we define a class with following format

public class Field {
    @SerializedName(\"name\")
    public String name;
    @SerializedName(\"category\")
    pub         


        

Answer 1

Instead of parsing with Field.class, can't you parse it into a JsonObject.class instead? Then use JsonObject.get():

import com.google.gson.JsonObject;

Gson gson = new GsonBuilder().create();
JsonObject jsonObject = gson.fromJson(content, JsonObject.class);
String serializedName = jsonObject.get("name").getAsString();

Note that .getAsString() will return it as a String without embedded double quotes, compare this to when you call toString().

One thing I was trying to do was serialize an enum field, which is not an object. In that case, you can serialize using JsonElement.class, since it's just a primitive:

import com.google.gson.JsonElement;

Gson gson = new GsonBuilder().create();
JsonElement jsonElement = gson.fromJson("\"a\"", JsonElement.class);
String serializedName = jsonElement.getAsString();

Use reflection to retrieve the Field object you want. You can then use Field#getAnnotation(Class) to get a SerializedName instance on which you can call value() to get the name.
