Change color of drawable in PagerTabStrip

Question

I'm using PagerTabStrip with a ViewPager to go between the different views of my app and it works well. I use drawables as the PageTitles with this method:

This also works really well, I do however want to change the colors of the drawables when they are selected, is there a way to do this? I use a onPageListener, so I do have a callback when a certain page is selected, I simply don't know how to change the color of the given Page-title drawable when that page is selected. For text there is a build-in method, but I can't find any information regarding drawables in the official documentation.

You know how to color drawables, but do not know how to set them back. right? — rupinderjeet, Feb 06 '18 at 10:48
Yes, I can always add a colored drawable to the PagerTabStrip, but after it has been set I'm not sure how I should update the color of the drawable. — Felix Eder, Feb 06 '18 at 11:04
If you have drawable reference, you can `drawable.setColorFilter(0xffff0000, PorterDuff.Mode.SRC_ATOP);` to make it red. Try it. — rupinderjeet, Feb 06 '18 at 11:50
That works perfectly, thanks a lot! I'll post the answer as a solution. — Felix Eder, Feb 06 '18 at 13:59

As @rupinderjeet stated in the comments, I solved it by keeping the drawable in an array before adding them to the PagerTabStrip. Since I had a reference to the drawables, I simply added a method that changes the colors of the drawables and call it from my onPageListener from my ViewPager. Works like a charm!

drawable.setColorFilter(0xffff0000, PorterDuff.Mode.SRC_ATOP);
