When do I need inflaters?
<p>I'm reading the book 'Hello, Android'. In the Sudoku example, it uses a options menu. It needs a MenuInflater that we use to read the menu definition from XML and turns it into a real view.
To use button, textview, or many other views, I don't need to inflate them.</p>

<p>My question is, in what situations, I need inflaters? Why doesn't Android treat menus like other views?</p>
