Android use both background image and background color

Question

I am used to writing things in html and one of the things I commonly do is make partially transparent patterns so that I can just change the background color instead of having to make a separate image for each color. I was wondering if there was something similar I can do on the Android. Right now I have a small image (5x5 pixels) that I repeat using an xml file in the drawables folder. It is used in the background of a scroll view which right now has a linear layout inside. Switching to a relative layout so that I can have an imageview would require a lot of programming changes so I'm wondering if there isn't an easier way.

Everywhere I have looked for a solution, the answers are a year or two old and they say to use two separate views, but it just seems like this is something that should have been implemented by now. And yes from a programming standpoint changing colors is just as easy as changing images, but it would just be a lot easier to be able to change the color instead of having to make an image for each new color.

Answer 1

You can use a Layer List drawable to achieve this. First add the color, then the bitmap.

If you prefer to create it programmatically instead of via resource files, use the LayerDrawable class.

Answer 2

<color name="black">#000000</color>

Now if i want to use opacity than you can use below code :-
