Android Dialog弹出对话框整理总结

对话框的概念：

对话框是提示用户作出决定，输入额外信息或显示某种状态的小窗口，通常不会填充整个屏幕，用于进行一些额外交互。

对话框的特点:

1, 当前界面弹出的小窗口.

2, 用户要与它进行交互, 可以接收用户输入的信息, 也可以反馈信息给用户.

Dialog类是dialog对话框的基类，Dialog基类中并没有定义界面，所以如果使用dialog类设置弹出框，需要使用xml自定义UI。系统自带了几个dialog派生的弹出框，并设置好了UI，可以直接调用系统自带的dialog衍生品，具体如下。除此之外，activity和fragment也可以作为dialog样式弹出使用，比如DialogFragment，使用 DialogFragment 管理对话框可确保它能正确处理生命周期事件，如用户按“返回”按钮或旋转屏幕时。

java.lang.Object

Known Direct Subclasses
AlertDialog, CharacterPickerDialog, MediaRouteChooserDialog, MediaRouteControllerDialog, PresentationKnown Indirect Subclasses
DatePickerDialog, ProgressDialog, TimePickerDialog

使用Alert Dialog等衍生类定义对话框

先上效果图：

下面是代码：
