Android UI组件进阶(2)——仿Windows对话框

在开始本章前先祝大家中秋节快乐哈,相信很多上班的朋友都是放三天假的哈！

有时间的话回家陪陪父母吧!树欲静而风不止,子欲养而亲不待!岁月不饶人!

好了,道理和祝福语就说到这里了,今天给大家准备的是模仿Windows风格对话框!

效果图:

相信大部分的AlertDialog都是下面这个样子的:

今天给大家讲解的对话框是下面这样的:

对比两种对话框,站在用户的角度,相信你更加钟情于第二种颜色鲜明的对话框

好了下面就开始讲解如何制作模仿windows风格的对话框吧!

代码的逻辑流程:

其实就是自定义对话框的布局,然后加载以及完成相应的事件处理而已！

核心代码解析:

①按钮点击效果:btnexit_selctor.xml

<?xml version="1.0" encoding="utf-8"?>
