Tunning up Activity with dialog theme

Question

I need to launch a Dialog from home screen widget, so I created an Activity with android:theme="@android:style/Theme.Dialog"

The problem is, that I would like make it look like standard dialog window ( buttons on the gray background, font and text size, paddings etc), like here:

This is how my "dialog" Activity looks like:

Is there some standard way (theme?) to make it look like standard system dialogs? Or do I have to imitate it in my own layout?

Answer 1

The top dialog is built using the AlertDialog.Builder, to create a simple dialog you should use that class.
