Which control would be a better fit to this problem?

I have a GridView of thumbnails; the user can click on a thumbnail to view the larger, full sized image. This "full sized" image is to be fetched from a remote server. When the user is viewing a particular image he should be able to cycle through all of them by swiping his fingers on the screen(like leafing through pages of a book).

1. What component should be used to display the larger version of the bitmap? I thought of using a ViewFlipper as it only seems logical to me. But I haven't used it before and am not sure of how I will create a new View every time, dynamically and pass it to the Flipper. Any tutorial that exemplifies this would be great.
2. Is there any other way to approach this problem?

Answer 1

It may take some work to integrate into your own project (I know because I've done it) but look at the solution from the Android source's Camera app in ViewImage.java; they use a scrollable/zoomable touch view that has auto-hiding controls overlaid for zoom and next/previous buttons. There's a lot of extra stuff in there too that needs decoupling before you can use it in your own app, but that's the core idea from a UI standpoint.

It'll also be familiar to your users; if there's no compelling UI reason to surprise your users with an image detail view that does something new, use the same one they're used to from the built-in Camera/Gallery app.

For what it's worth, the 2.1 camera app seems to do away with the next/prev buttons and replaces them with swipe left/right gestures.
