There are two ways to achieve this

  • use the following theme for activity.

android:theme="@android:style/Theme.Translucent"

  • Set background of the activity as a trans parent png image or a transparent code

eg.

android:background="@drawable/transparent_bg"

or

android:background="#33BBFFFF"

this is a semi transparent color
