I have a ListView that can have one or more clickable items. When I
apply a rotate animation the coordinates that are clicked correspond
to the original position of the ListView items. For example a list
with one item in portrait mode rotated 180 degrees will have the item
upside down on the bottom of the screen, but the item gets the click
event when I click the top of the screen. 180 degrees is just an
example I want to be able to move an arbitrary angle. I've looked
through all the listView properties but none seem to have any effect
on the clickable coordinates. I would assume
willChangeTransformationMatrix would do the trick but it doesn't,
neither does invalidate or invalidateViews.
Is there a property I'm overlooking or how would I go about moving the
coordinates to the right place (clicking the item from the rotated
position not the original)?
Alternatively is there a way to rotate the listView without animation
and achieve the effect I'm expecting?
Thanks
sample code- list items highlight correctly when clicked, rotate with
dpad_center, after rotated items highlight when original position is
clicked. I've tried animating the animation, animationSet, and
layoutAnimationController all same result.
