title: Android Borderless Dialog
body: <p>I have created an AlertDialog using AlertDialog.Builder, but the Dialog border takes up too much space on the screen. How do I remove the border? I have tried using another Activity to emulate the dialog with a transparent background, but the dialog is used repeatedly, and creating a new Activity every time introduces a significant amount of lag.</p>
  
  <p>The answer from <a href="https://stackoverflow.com/questions/704295/android-show-an-indeterminate-progressbar-without-the-dialog">here</a> mentions that it can be found in the ApiDemos, but i can't seem to find it.</p>
