用法，和 NormalDialog用法一致：

final PassWordDialog p = new PassWordDialog(mainActivityActivity);
p.title("请输入验证码")
        .btnText("取消", "确定")//
        .btnTextColor(Color.GRAY, Color.GREEN)
        .style(NormalDialog.STYLE_TWO)//
        .titleTextSize(23)//
        .widthScale(0.4f)
        .showAnim(new BounceTopEnter())//
        .dismissAnim(new SlideBottomExit())//
        .show();
