Using the compatibility library with the Fragment Pager Support
example, I'm noticing some odd behavior in the scrolling.
To reproduce:
1. Run the sample FragmentPagerSupport (v4)
2. From Fragment #1 scroll up and down using the dpad or trackball.
- This works as expected.
3. Swipe to move to Fragment #2.
4. Scroll up and down using the dpad or trackball.
Nothing appears to happen. However, you are actually scrolling on
Fragment #1. Not the visible fragment. In fact, you can use the left/
right arrows (trackball roll left/right) to move the focus to the
offscreen fragments and scroll around on those.
If you connect an item click listener to the lists and display a toast
message, you will see that while scrolling on the off-screen
fragments, pressing the dpad-center or trackball, you will trigger the
click response for that offscreen list item.
I noticed this in my own application and confirmed with the sample
app.
Is there any way around this? Can we restrict focus/scrolling only to
the onscreen fragment?
Thank you.
Best Regards,
Eric
