I want to change the color of button text as image change in ImageSlider. I used one library for making ImgeSlider.

Link for ImageSlider is:

https://github.com/denzcoskun/ImageSlideshow

My code is:

  //******************************** code for Image Slider**********************
    ImageSlider imageSlider = findViewById(R.id.imageSlider);
    ArrayList<SlideModel> imageList = new ArrayList<>();
    imageList.add(new SlideModel(R.drawable.img1, ScaleTypes.CENTER_CROP));
    imageList.add(new SlideModel(R.drawable.img2, ScaleTypes.CENTER_CROP));
    imageList.add(new SlideModel(R.drawable.img3, ScaleTypes.CENTER_CROP));
    imageSlider.setImageList(imageList,ScaleTypes.CENTER_CROP);

You can either use setItemChangeListener or call the listners below

imageSlider.setItemClickListener(object : ItemClickListener {
        override fun onItemSelected(position: Int) {
         button.setTextColor(Color.parseColor("#ff0000")); 
                          or
         button.setTextColor(getApplication().getResources().getColor(R.color.red));
                          or
        button.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.red));
        }
    })

inside source of this lib, in ImageSlider class, you can find setOnItemChangeListener - use this method, register own interface and change text color inside called method
