In my android app, I need to design a Welcome Screen which will be shown to the user only once after the app is installed and opened. The app in question is a database driven app and I would love to include some 3 - 4 screens to help the user create re-usable resources for use within the app and a few tips. They would be Dialog Alerts with the last welcome screen showing the "Do Not Show Again" checkbox.
这个问题还真是，如何显示欢迎屏幕只有一次。任何帮助或指针的效果是多少AP preciated。
The problem really is, how to show the welcome screen just once. Any help or pointers to that effect are much appreciated.
推荐答案
保存在preferences一个标志，当你启动应用程序，你已经做了欢迎屏幕的东西之后。检查这个标志，你在欢迎屏幕前。如果标志是present（换句话说，如果它不是第一次了），没有表现出来。
Save a flag in the Preferences when you start up the application, after you've done the welcome screen stuff. Check for this flag before you show the welcome screen. If the flag is present (in other words, if it's not the first time), don't show it.
