Вот решение нашла:

for (int i = 0; i < iconResourceArray.length; i++) {

            ImageView imgView= new ImageView(RoutesActivity.this);
            imgView.setImageResource(iconResourceArray[i]);
            imgView.setPadding(0,0,0,0);
            tabLayout.getTabAt(i).setCustomView(imgView);

        }
