How do you make these buttons?

Question

I am trying to make buttons of a similar nature to the buttons seen in the google+ app. Do you just declare these in XML like a regular button and just apply a custom style? Does anyone know generally what these buttons are and a sort of method for how to generate a look like this?

Answer 2

It can be anything that registered with a OnClickListener , something like: ImageButton , ImageView , a Layout w/ background image...

However, in my opinion, ImageButton is the best w/ some pre-defined functions for button-like effects/shapes.
