android - Fully opaque ImageButtons layered over a CameraPreview -

-

i have framelayout containing camerapreview , relativelayout. relativelayout contains imagebuttons. thus:

<framelayout>   <camerapreview/>   <relativelayout>     <imagebutton/>     <imagebutton/>   </relativelayout> </framelayout>

i'm using camerapreview live-preview image coming camera. works correctly. imagebuttons display drawable bitmaps, , appear on camera preview.

the problem buttons semi-transparent: camera image visible in background. want them fully-opaque make them more visible. how do this?

i've tried calling setalpha() on buttons doesn't appear have effect.

can suggest how can make buttons opaque?

the problem turned-out image buttons had no background drawable resource , weren't inheriting 1 of views in parent hierarchy.

adding android:background="@android:drawable/btn_default" imagebutton's xml definition solved problem.
