在开发过程中，与用户交互式免不了会用到对话框以实现更好的用户体验，所以掌握几种对话框的实现方法还是非常有必要的。在看具体实例之前先对alertdialog做一个简单介绍。alertdialog是功能最丰富、实践应用最广的对话框，它可以生成各种内容的对话框。但实际上alertdialog生成的对话框总体可分为以下4个区域：图标区、标题区、内容区、按钮区。
这里总结了九种对话框的实现方法，有需要的朋友可以来学习下了
除了popupwindow实现稍微麻烦一点，其他形似都相对简单，熟悉2便即可

以上是android开发必知 九种对话框的实现方法，代码主要用alertdialog生成的对话框，它的功能丰富、使用最广。
