title: How can I get a Dialog style activity window to fill the screen?
body: <p>I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works.</p>
  
  <p>Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen.</p>
  
  <p>There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?</p>
