From some tutorials I cant understand what mean "View". More accurately - I cant understand how many views can displays at same time? In tutorials what I read, only 1 view displays at same time, and it always occupies full screen. For example if I need show popup panel, it is normally to make new view for this popup panel? or better to include this popup panel into another view?
You can show as many Views as you need, it is not about MVP pattern. From View perspectives MVP describes relation between Model-View-Presenter, but any View could have child Views with own presenters and bound model.
So common scenario - having main View which divides own space/layout between set of child views each of them has own Presenter and uses own/shared model (depends on application specifics and design).
