Answer 1

To change color you can use below code

 editText.getBackground().mutate().setColorFilter(your_color), PorterDuff.Mode.SRC_ATOP);

And to set different color underline for EditText view on focus change

    editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                editText.getBackground().mutate().setColorFilter(getResources().getColor(android.R.color.holo_purple), PorterDuff.Mode.SRC_ATOP);
            }else {
                editText.getBackground().mutate().setColorFilter(getResources().getColor(android.R.color.holo_red_dark), PorterDuff.Mode.SRC_ATOP);
            }
        }
    });
