Deserializing Generic Types with GSON

Question

I have some problems with implementation of Json Deserialization in my Android application (with Gson library)

I\'ve made class like this

public clas         


        

Answer 1

So the above answer didn't work for me, after trial and error that's how my code ended:

public class AbstractListResponse {
    private List result;

    public List getResult() {
        return this.result;
    }
}

The important part here is the method signature, including the '< T >' on the left.

protected  AbstractListResponse parseAbstractResponse(String json, TypeToken type) {
    return new GsonBuilder()
            .create()
            .fromJson(json, type.getType());
}

When calling Gson, the method receives the TypeToken of the generic object.

TypeToken> typeToken = new TypeToken>() {};
AbstractListResponse responseBase = parseAbstractResponse(json, typeToken);

And finally the TypeToken can use MyDTO, or even a simple object, just MyDTO.
