You saved me :D Thanks!
Thanks!!!
Excellent work! This saved me a lot of headache.
Mantap jiwa..
Works perfect! Thanks
Not working for me on V27.1.1
I've tried both java and xml ways but in vain.
Checked on emulator running on 5.0 and physical device running on 7.1.1
Any ideas ?
Thanks so much i was wondering if there is any solution or not but now i am feeling very lucky thankyou so much
Am having same issue with BottomSheetBehavior, any fix for that?
Why isn't this incorporated in the official release so far? I have a Horizontal recyclerview inside a vertical recyclerview, which is inside a nestedscrollview. I'm now having issues with the usability of the horizontal scroll. It works very different from the Google Play app, which has good UX, I need to know if there's a standard solution for this provided by Android.
@harsha-main I have the same layout with horizontal recycler inside a vertical recycler inside a coordinator layout. One think that fixed my issues with the app bar layout was setting android:nestedScrollEnabled="false"
on the horizontal recycler. It fixed our issues with our collapsing header so it might fix your issues.
Thanks!!!
Thanks Chris ! 🙌
Thanks!
Oh God!!!
Finaly!!!
