创建简书账号差不多一年，想想还没有写过什么内容。刚好最近想沉淀一下自己，总结一下自己工作以来的所接触和用过的有价值的东西。既是总结自己，也希望分享给大家。后面我会陆续更新我的博客
所以，第一篇文章从什么开始呢，那就从封装一套通用的Dialog提示框开始吧。这套dialog是我在工作中自己用建造者模式封装的，使用起来很方便，今天分享给大家。
如果对建造者模式不太了解的小伙伴请自行查阅资料，此处不进行进一步探讨。
先看看效果图吧。
双按钮
三按钮
---- 如何使用 ----
准备步骤(具体代码见后文"源代码")：
1、创建布局文件：dialog_layout.xml
2、创建圆角背景：dialog_round_bg.xml
3、如果需要我图上默认的icon,这是我直接从google发布的material-design-icons-master中拷贝的：
4、创建自定义dalog类：BuilderModeDialog.class
开始使用：
调用例子
---- 方法说明 ----
---- 源代码 ----
1、dialog圆角背景：dialog_round_bg.xml
