Android,每个视图模式的活动?或者在更少的活动类中切换语句?

创建显示列表的基ListActivity。

然后,为每个视图模式创建单独的派生类。

You do want a separate Activity per view. Once a view isn't visible anymore, the OS can reclaim that activity. This helps resource management. Plus, when a view it an Activity it gets to do interesting things in response to user input (for instance, when the search button is hit).
