How to remove filled colors?
My code:

here I have two imageview 1.aplhabetbackground 2.alphabetchangingbackground.
So according to my code when next button clicked the 2nd data from alphabet store array its image will display in the imageview. And so clicking on the next button it will shows next image and so.
here I have used touch event in alphabet background .So when image is display i can touch on the screen and filled with the selected colour.
But I need while clicking the next button the filled color should remove from it. How to do
