Android: how to create a transparent dialog-themed activity

Question

My original goal here was a modal dialog, but you know, Android didn\'t support this type of dialog. Alternatively, building a dialog-themed activity would possibly work.

Answer 1

The easiest way that I have found is to set the activity's theme in the AndroidManifest to android:theme="@android:style/Theme.Holo.Dialog" then in the activity's onCreate method call getWindow().setBackgroundDrawable(new ColorDrawable(0));
