Android: How can I get Gson LinkedTreeMap values?

Question

I'm trying to simply get values from my Gson Object, so in my "city" Object:

I need to get the name "first" and the boolean value from "isSelected".

I just wrote a new class "KeyPairBoolData":

class KeyPairBoolData {
    int id;
    String name;
    boolean isSelected;

}

but I have no idea what should I write in the new class to get these values, here is how I'm trying to get it:

List<KeyPairBoolData> city = gson.fromJson(myListArray, listArray.getClass());

any idea? Thanks!

Try this:

Method to deserialize generic collection:

Type listType = new TypeToken<ArrayList<KeyPairBoolData>>() {
                    }.getType();
List<KeyPairBoolData> keyPairBoolDataList = new Gson().fromJson(jsonArray, listType);

Import : import java.lang.reflect.Type;
