On Android, the touchFeedback property applies ripple effect to a view's "background" when the view is touched. When applied to a Ti.UI.ImageView, this ripple effect can't be seen if the image is opaque (ie: not transparent) and completely covers the view. This is not a bug, but app developers would like the ability to apply a touch ripple effect to the foreground "image".
Add the following properties to Ti.UI.ImageView...
- imageTouchFeedback // boolean
- imageTouchFeedbackColor // optional string
When the new "imageTouchFeedback" property is set true, the ripple effect should be applied to the foreground image assigned via the "image" property.
For older Titanium versions, you can apply a touch ripple effect via the "backgroundImage" instead. The downside with this is that images are not loaded asynchronously via this property and the EXIF orientation is ignored.
