解析用に定義されたクラスは以下のとおりです
public class FeaturedPageData {
@SerializedName("status")
public String status;
@SerializedName("success")
public String success;
@SerializedName("events")
public ArrayList<Event> events = new ArrayList<FeaturedPageData.Event>();
public static class Event {
public Event() {
}
@SerializedName("name")
public String name;
@SerializedName("end_time")
public String end_time;
public Images images;
}
public static class Images {
public String ratina_big;

解析するために Json を呼び出している関数
Reader reader = new InputStreamReader(content);
GsonBuilder gsonBuilder = new GsonBuilder();
Gson gson = gsonBuilder.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES).create();
FeaturedPageData posts = new FeaturedPageData();
posts = gson.fromJson(reader, FeaturedPageData.class);
content.close();
handlePostsList(posts);
"success" と "status" の値が表示されますが、arraylist には name と end_time の null が表示されます
