user interface - Make Android Activity looks like dialog

Question

I am trying to open a dialog on widget click. I have solved the problem skinning the activity started on click with android:theme="@android:style/Theme.Dialog". Unfortunately I cannot reach the same look of a dialog.

This is the outcome:

Dialog from widget

Instead, I would like to reach this result (except for the button, of course):

Desired dialog from widget

(the widget dialog you can see keeping the screen pushed)

As you can see there are some differences: the color of the list items, the color of the text and the list item separator. Is there a predefined theme/style to obtain the same look of a standard dialog? If not, what are the steps to follow to reach that result?

I have seen that the widget provided by FoxyRing has the behaviour I would like to have.

Answer 1

Why not use a "traditional" Main Activity with a transparent background layout

and call a standard dialog from it ?

... well if I understood you correctly, that would make the trick in a very easy way, isn't it ?
