 讲到自定义布局我就得多说一说了，为什么要多说一说呢？
其实自定义布局在Android的开发中非常重要 因为它能让开发者做出自己五彩缤纷的Activity 而不用去使用系统枯燥的界面。

自定义dialog有什么好处？

比如我们在开发过长当中 要通过介绍系统发送的一个广播弹出一个dialog . 但是dialog必需是基于activity才能呈现出来 如果没有activity 的话 程序就会崩溃。所以我们可以写一个自定义的 dialog 把它定义成一个activity
这样我们收到一条打开dialog的广播后 直接启动这个 activity  程序正常运行~~

这就是自定义dialog的好处。

注明：例子中只是写了自定义dialog 没有把它单独的写在一个activity中

这节学习安卓的各种对话框。包含 1）一个确认按键的对话框 2）一个确认键和取消键的对话框 3）包括三个按键的对话框 4）下拉列表对话框 5）单选下拉列表对话框 6）多选下拉列表对话框 7）进度条对话框 8）进度条提示对话框 9）自定义对话框 效果如下：

 讲到自定义布局我就得多说一说了，为什么要多说一说呢？
其实自定义布局在Android的开发中非常重要 因为它能让开发者做出自己五彩缤纷的Activity 而不用去使用系统枯燥的界面。
