Three listviews in one screen

I have an app on iPhone with cascading design like on the picture, and I'd like to port it to Android. Is there a simple and recommended way开发者_C百科 to do this?

The section menu on the left (Section A, B,C,D) is the first that the user needs to select, then the user needs to pick a category in the middle (all, popular, pc, xbox,...), then he is presented with a list of articles for chosen category.

I could imagine doing it with three ListViews, but then the app could also listen to a swipe gesture to make the rightmost ListView "full screen", and hide the first two listviews. I could implement a swipe listener for the whole activity and set first two listviews' visibility to hidden, right?

Are my assumptions correct and would this be the right way to do this?

It could definetly work the way you explain it - if the design is good is another discussion. Personally I'm not a fan of throwing in endless amounts of data in one screen, when the space is as limited as it is on most mobile phones (I would probably do it with 3 different screens with a ListView on each)

Implementing the mentioned swipe gesture is doable and you could certainly just hide the two other ListViews with the function setVisibility( View.GONE ).

Hope it helps.

1. You might want to use the new fragments API, it's specifically built for this kind of thing (and it's compatible all the way down to Android 1.6). Also, as KasperMoerch says, putting all that info on a small screen can get ugly. Using fragments will make it easier for you to gradually increase the amount of information displayed as the screen size increases.
2. I'm not sure you can just listen for a swipe gesture over an entire activity like that. I think you have to wrap the fragments in a custom view (for example an extended LinearLayout) and do the swipe listening there. However, achieving a finger-tracking animation (i.e. where the rightmost pane follows the finger precisely as it swipes across) is a pretty daunting task (I wouldn't really know where to begin, probably in the custom view though). The best way (I think) to do it is to make a compromise and just start an animation (right-to-left slide) when you detect a swipe. However, the simplest solution is to not animate at all.
3. You can also take into consideration dropping the swipe gesture altogether and just providing an "expand" button.
