transparent activity's full screen on 2.3

Question

I was using this xml style:

<style name="Theme.Transparent" parent="@android:style/Theme.Translucent.NoTitleBar">       

This was showing a tansparent layout with full screen, no title bar or status bar on the top in android 2.1 and 2.2. However, when I tested the application on 2.3, the same activity was showing the home screen status bar on the top (battery etc).

I had to enter these lines to my java code onCreate:

requestWindowFeature(Window.FEATURE_NO_TITLE);     
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); 

To get it to remove any status or title bar from the top.

Can anybody shed light why this difference between 2.2 and 2.3?

Answer 1

You can set the theme to:

<style name="Theme.Transparent" parent="@android:style/Theme.Translucent.NoTitleBar.Fullscreen">"

And that should hide both the title bar and fullscreen in every version.
