Activity快速转换为Diglog

其他内容不变，只需要修改AndroidManifest.xml 中Activity注册是添加android:theme="@android:style/Theme.Holo.Dialog" 即可<activity
android:name=".activity.DialogActivity"
android:screenOrientation="portrait"
android:theme="@style/Coustom_Dialog" />
<activity边用边更新

Android Studio在SVN上创建分支
1、项目右键，SubVersion->Branch or Tag...
2、在弹出的对话框里面，Copy To的菜单下面的Base URL里面选路径，点下面的加号，确定分支的路径，点击OK
3、然后写个注释（comment），点击OK，分支创建完毕。
4、比较的时候，项目右键，SubVersion->Compare With branch...比较合并
