Fading Edges Working Only On Top And Left
I made a custom ImageView that supports basic scrolling through calls to View.scrollBy() in a GestureDetector. I wanted to add some feedback on the reaching of scrolling bounds so
Solution 1:
It seems that the problem is in getBottomFadingEdgeStrength()
and getRightFadingEdgeStrength()
, or better, in the fact that I didn't override them to work with my custom view.
These protected methods tell view's draw()
when to draw the fadings (and how strongly -- see what a ScrollView
does when you get close to the scrolling limit).
For top and left edges it's easy because the limit is 0
in both cases and the default implementation works (in its on/off manner), but for the other two I need to override the methods to take into account my own scrolling bounds (in my case, the drawable dimensions).
