Methods in DefaultHeaderTransformation adjusted to make the ActionBar-PTR progress bar color styling work again

DefaultHeaderTransformer.java

public void setProgressBarColor(int color) {
    if (color != mProgressDrawableColor) {
        mProgressDrawableColor = color;
        applyProgressBarSettings();
    }
}

private void applyProgressBarSettings() {
    if (mHeaderProgressBar != null) {
        final int strokeWidth = mHeaderProgressBar.getResources()
                .getDimensionPixelSize(R.dimen.ptr_progress_bar_stroke_width);

        mHeaderProgressBar.setIndeterminateDrawable(
                new SmoothProgressDrawable.Builder(mHeaderProgressBar.getContext())
                        .color(mProgressDrawableColor)
                        .strokeWidth(strokeWidth)
                        .build());

        ShapeDrawable shape = new ShapeDrawable();
        shape.setShape(new RectShape());
        shape.getPaint().setColor(mProgressDrawableColor);
        ClipDrawable clipDrawable = new ClipDrawable(shape, Gravity.CENTER, ClipDrawable.HORIZONTAL);

        mHeaderProgressBar.setProgressDrawable(clipDrawable);
    }
