I need to be able to set the background as completely transparent. Seems no one has tried it before . Please help.
If Im correct we need to make framelayout backgrund totally transparent . But no effect taking place on doing it.
Thanks for all your reponses , but none ofthem seems to be working so far.
To clarify further , I need to make the background below the listview to be transparent.
That is, when the drawer is opened completely .There is a partial screen from the below activity that is visible. It shows as blurred greyed out with some text visible. I need that to be perfectly visible.
Do I need to change some themes in activity?
The following is the complete layout xml

     The drawer is given a fixed width in dp and extends the full height of
     the container. A solid background is used for contrast
     with the content view.
