converting json string with Gson for generic model

问题

i have class like this

   T item;
   List<T>;
}

so how can to deserializeding String in this pattern to one generic class withgson.fromJson(targetString,...)?

i glad to used in retrofit library where Response is returned parameter in desired interface

回答1:

convert list to gson

public <T> String setList(List<T> list) {
    Gson gson = new Gson();
    return gson.toJson(list);  
}

convert gson to list

public List<(desired class)> getList(){
    Gson gson = new Gson();
    String json = (pass json string);
    Type type = new TypeToken<List<(desired class)>>() {}.getType();
    return gson.fromJson(json, type);
}
