android - transparent activity's full screen on 2.3 -

-

i using xml style: 

<style name="theme.transparent" parent="@android:style/theme.translucent.notitlebar">

this showing tansparent layout full screen, no title bar or status bar on top in android 2.1 , 2.2. however, when tested application on 2.3, same activity showing home screen status bar on top (battery etc).

i had enter these lines java code oncreate:

requestwindowfeature(window.feature_no_title);       getwindow().setflags(windowmanager.layoutparams.flag_fullscreen, windowmanager.layoutparams.flag_fullscreen);

to remove status or title bar top.

can shed light why difference between 2.2 , 2.3?

you can set theme to:

<style name="theme.transparent" parent="@android:style/theme.translucent.notitlebar.fullscreen">"

and should hide both title bar , fullscreen in every version.
