How do I create a transparent Activity on Android?

Question

I want to create a transparent Activity on top of another activity.

How can I achieve this?

Answer 1

I just did two things, and it made my activity transparent. They are below.

1. In the manifest file I just added the below code in the activity tag.

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

2. And I just set the background of the main layout for that activity as "#80000000". Like

   android:background="#80000000"
   

It perfectly works for me.
