Overlap a transparent foreground of a Relative layout to make text views color gray transparent inside Relative layout

I tried following:

Created a frame layout containing that relative layout and made foreground /background color transparent. But I got transparent layout above my Relative Layout But Cannot see the textviews of Relatives layout which was initially of dark black color.

Also tried dynamically by creating a drawable with transparent color setting it to foreground of frame layout containing that relative layout. getting still the same result.

Any help would be greatly appreciated ?
