-----------------------------------
Summary: Update Scroller OverScroll Behavior For Android
Key: FLEX-33709
URL: https://issues.apache.org/jira/browse/FLEX-33709
Project: Apache Flex
Issue Type: Improvement
Components: Spark: Scroller
Affects Versions: Apache Flex 4.9.0
Environment: Android 4.x+, all versions of Flex
Reporter: Josh Janusch
Priority: Minor
In Android 4.x and above, the default scroll behavior is not the
elastic/bounce-back behavior found in iOS (thanks to lawsuits from Apple).
Currently, the Spark Scroller uses the iOS behavior and looks out of place on
Android.
Better explanation:
In iOS, if you scroll and it hits the edge of the viewport, the page keeps
scrolling but encounters friction so that the further you go away from the
edge, the slower it scrolls. When you let go, the viewport snaps back to its
limits. This is currently how the Spark Scroller always works.
In Android, if you scroll and hit the edge, the viewport stops moving. A blue
glow appears at the edge of the viewport that gets larger and brighter as you
try to scroll further from the edge. If you stop moving for a set of time or
lift your finger from the screen, the glow fades away.
The scrollbar currently mimics iOS and Android 2.x behavior, and even seems to
mimic the skin of Android 2.x. It'd be great if the scroller, a fundamental
piece of any app, could be updated to fit more in line with recent versions of
Android
