前言：
公司项目弹窗的地方比较多，弹窗的样式也有很多种，所以就根据项目里的多种弹窗样式，整合成一个可重复利用的全局弹窗，可自己手动再次自定义。
有多种样式：最简单的文字提示弹窗（有标题、详细信息，还有确定、取消按钮，这些皆可单独存在），首页一张大广告图片弹窗，有单选、多选（列表多选）、勾选弹窗，输入框弹窗（可以自己修改为几个输入框都行），TextView弹窗，还有图片和文字结合的说明弹窗，还有自定义弹窗（可以自行添加想要添加到弹窗上的视图）；弹窗右上角有关闭按钮，可以自行选择是否展示，等等功能自行探索.....
具体可以自己尝试，先说一下最简单的文字提示弹窗，如下图所示：

部分具体实现如下：
