                sb.append("<img src=\"").append(R.drawable.button1).append("\"/>").append("<font color=\"6f6f6f\">按钮上加图片效果</font>");;
                Spanned span = Html.fromHtml(sb.toString(), imgGetter, null);
                btn.setText(span);
                sb = null;
    }
}

采用Spanned也不是什么新鲜事了，呵呵。这里只提供一种思路。不止Button，任意可以显示文字的View都可以这样做。
