I have layout name MyLayout extends LinearLayout for contain a lot of view
and show my layout in listview(via my custom adapter)



and then I setBackgroundColor in constructor of MyLayout as Color.RED

it work

but when I set listView.setSelector(grColor); //grColor is GradientDrawable
it don't show selected color

I try to change background color of my view as Color.argb(50, 255, 0, 0)
now it show selected color
but it's red color + backgroundcolor(black)
it's not red

how to set Selector and set View backgroundcolor as Color.RED???

thanks
