Gson turn an array of data objects into json - Android

Question

Currently I am working on a native android app with webView front end.

I have something like:

public class dataObject
{
  int a;
  String b;
}
         


        

Answer 1

My version of gson list deserialization using a helper class:

public List getList(Class type, JSONArray json) throws Exception {
    Gson gsonB = new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss").create();

    return gsonB.fromJson(json.toString(), new JsonListHelper(type));
}



public class JsonListHelper implements ParameterizedType {

  private Class wrapped;

  public JsonListHelper(Class wrapped) {
    this.wrapped = wrapped;
  }

  public Type[] getActualTypeArguments() {
    return new Type[] {wrapped};
  }

  public Type getRawType() {
    return List.class;
  }

  public Type getOwnerType() {
    return null;
  }

}

Usage
