Yes, You are correct.

But sometimes Presenter have to interact with adapter data.

Guess that Facebook support Likebutton at each posting.

when user click Like, it should have network api. It means Presenter have to know data, at least id of data.

In this case, Many people implement wrong. In Presenter, it calls View.getClickedData() .

After network, Presenter will update data to notify successful network.
In this case, also Between Presenter and View, they communicate many time.

So in this posting, I want to explain how to make these decoupling.
