推荐答案

看起来我有解决方案:

private void makeCollapsingToolbarLayoutLooksGood(CollapsingToolbarLayout collapsingToolbarLayout) {
    try {
        final Field field = collapsingToolbarLayout.getClass().getDeclaredField("mCollapsingTextHelper");
        field.setAccessible(true);

        final Object object = field.get(collapsingToolbarLayout);
        final Field tpf = object.getClass().getDeclaredField("mTextPaint");
        tpf.setAccessible(true);

        ((TextPaint) tpf.get(object)).setTypeface(Typeface.createFromAsset(getAssets(), "Roboto-Bold.ttf"));
        ((TextPaint) tpf.get(object)).setColor(getResources().getColor(R.color.ice));
    } catch (Exception ignored) {
    }
}
