Common Presenter for multiple views

[Charan]

Hi,

I have a presenter which makes calls to Handler and get the data from server

same data is needed for another widget which is a miniature version of the existing view, but this will present all time in application.

Here what i have common is calls to handler, same handler and action objects.

What is the best way to design.

My possible solution :

1) Writing one Common class which has access to the dispatcher object (Inject through Ginjector), use the methods to get data.

But as per MVP architecture, dispatcher usage is restricted to presenter only, but this is non-presenter class.

2) Is there any otherway?

Hi,

I assume that in your Presenter's onBind() you make a call to retrieve the required data.

And, that if the call is successful (onSuccess) you update the associated View (via a call to one or more methods declared in the Presenter's MyView interface e.g. setResultSet() or SetResult()).

Once you have the data you can use a custom event to notify the "other" view.

Cheers

One more issue,  miniature widget is required data all the time regardless of the actual view is been instantiated (Visited) or not.
