Pinch Zoom in Android

问题:

I have a layout, which include some TextViews and ImageViews. Haven't they created an easy way to include pinch zoom on an simple ScrollView/LinearLayout? I have watched some codes, but they work only on ImageViews.

Recently I found setDisplayZoomControls(boolean).

Is it possible to make this work on a layout with TextViews? If no, maybe somebody provides a code, which will zoom in/out my layout with pinch zoom.

Thanks.

Try using android-pinch, it is supposed to work on web-views as well http://code.google.com/p/android-pinch/

Also,

Take a look at this: http://code.google.com/p/android-multitouch-controller/

It will enable you to add multi touch handlers to almost any widget.

Note that due to some hardware problems on older devices, you might not always get the right result.
