Making a single class to hold all the Events that would be posted and listened by EventBus

Events.java

public class Events {

        public String getTag() {
            return this.getClass().getSimpleName();
        }

        }

    }

    public static class SwipeRefreshCancelEvent extends Event {
        public boolean enableRefresh;
        public SwipeRefreshCancelEvent(boolean enableRefresh) {
            this.enableRefresh = enableRefresh;
        }

    }
}

///Accessing the events like this

        System.out.println("Event received "+event.getTag());
        if (event.getTag().equals("SearchResultEvent")) {
