android - Tunning up Activity with dialog theme -

"postprint" itemprop = "text">

I need to start a dialogue from the home screen widget, then I created an activity with android subject = "@ android: style / Theme.Dialog"

the problem is, I want to make it look like a standard dialog window that (gray background, font and text Button, paddings etc on the shape, as it is here:

<"> This way my" dialog "activity looks like this:

< Img src = "https://imgur.co m / O7H1j Png "alt =" alt text ">

Is there a standard way (the theme?) it is to show the standard system communicate? Or do I have a copy in your own layout? < You can get the same look for the buttons below for weight specialties and backgrounds behind them. the use of structures. I hope that this helps
