Android - Generic Zoom

Are there any android zooming solutions that can be applied to a generic android view?

My app needs to push a lot of information onto the screen, and on some phones, screen is so small that this data becomes unreadable.

I want to get zooming functionality that works for textview's and image buttons in particular. I imagine a zoomView that works for these two built-in's would work for most of the others too.

I've looked around on the web and haven't found any easy solution yet. Most 开发者_Python百科of the discussion seems to be focused on zooming images or a webview.

If there is not an existing solution, can anyone suggest a good approach to take?

That is not possible except perhaps on Android 3.0. On Android 3.0 (API Level 11), you have getScaleX() and getScaleY() which might suit your needs.

Design a different UI optimized for smaller screens.

Or, use a ScrollView (or HorizontalScrollView) and use bigger widgets (effectively pre-zooming your content).

You can try to implement your own pseudo-zoom by changing the text size and button sizes based upon user input (e.g., options menus to zoom in/out), but I'm not sure how well that will work.
