How to use?

Use ValueInterpolator class and add this method to get the gradient for each row

    public int[] getGradientColors(int startColor, int endColor, int size) {
        int colors[] = new int[size];
        int startR = Color.red(startColor);
        int startG = Color.green(startColor);
        int startB = Color.blue(startColor);
        int endR = Color.red(endColor);
        int endG = Color.green(endColor);
        int endB = Color.blue(endColor);
        ValueInterpolator interpolatorR = new ValueInterpolator(0, size - 1, endR, startR);
        ValueInterpolator interpolatorG = new ValueInterpolator(0, size - 1, endG, startG);
        ValueInterpolator interpolatorB = new ValueInterpolator(0, size - 1, endB, startB);
        for (int i = 0; i < size; ++i) {
            colors[i] = Color.argb(255, (int) interpolatorR.map(i), (int) interpolatorG.map(i), (int) interpolatorB.map(i));
        }
        return colors;
    }
