Adding transparency programmatically using a android color resource

Question

There is a color in colors.xml without transparency. I do know that i can add transparency to colors.xml like #CC666666. But i need to add this transparency programatically.

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="list_section">#666666</color>
</resource>

in my Activity:

int color = getResources().getColor(R.color.list_section);
// put transparency here
myView.setBackgroundColor(color);

Answer 1

Guess bitwise OR could work. Something like

int transparentColor = 0xCC000000 | color;
myView.setBackgroundColor(transparentColor);
