常用的系统主题：
1
. 没有标题：
@android
:style/Theme.Black.NoTitleBar
2
. 全屏幕
@android
:style/Theme.Black.NoTitleBar.Fullscreen
3
. 透明
@android
:style/Theme.Translucent
4
. 桌面壁纸作为背景
@android
:style/Theme.Wallpaper
5
. 对话框
@android
:style/Theme.Dialog
对Activity的生命周期是否有影响？
练习：第一个Activity中有两个按钮，
一个弹出对话框主题的Activity，
另一个弹出对话框，测试二者对
第一个Activity生命周期是否有影响。
弹出对话框主题的Activity：
暂停状态，onPause()
弹出对话框
生命周期没有影响
使用场景：
1
. 对话框主题的Activity
例如：在桌面弹出短信内容对话框
对话框后面的Activity是其他App的，这时必须使用对话框主题的
Activity
2
. 对话框
需要使用Activity中的成员变量时
