### **简介**
|
||
> AlertDialog 向用户传递信息的弹出层。警报对话框
|
||
- 一般使用在通知用户需要确认的情况，具有可选标题和可选的操纵列表。标题显示在上方，操纵内容显示在内容区域，即下方
|
||
|
||
### **基本用法**
|
||
> 通常作为子窗口小部件传递给showDialog，后者显示对话框。
|
||
- 当**AlertDialog**的的元素过多过长时, 请优先考虑**SingleChildScrollView** 用来避免内容溢出
|
||
- 需要注意的是，由于AlertDialog 通常使用child的大小来调整自身大小，所以使用一些widget（如ListView，GridView和CustomScrollView）将无法正常工作
|
||
- 当需要给用户提供多个选项的供选择时，请使用SimpleDialog
