Setting opaque to custom color in android (setAlpha)

Question

How can I get my color and set opaque to it?

int myColor = getResources().getColor(R.color.ColorPrimary);

Answer 1

You can use ColorUtils.setAlphaComponent to create a new color value with the same RGB but different alpha. The alpha value needs be from 0 - 255 so it would look something like this:

int color = getResources().getColor(R.color.ColorPrimary);
int color50percent = ColorUtils.setAlphaComponent(color, 128);
