how to get bottomSheet to open from the top?

Question

I\'m opening a NestedScrollView in my app and so far it opens from the bottom of the screen. How do I make it open from the top?

I tried removing the following line:

Answer 1

I guess it is not possible using google's design library, since by design this is meant to appear from the bottom.

https://material.io/guidelines/components/bottom-sheets.html
"Bottom sheets slide up from the bottom of the screen to reveal more content."

Trying using this modified version of flipboard's bottomsheet

I have added an attr to control whether the bottomsheet should appear from the top.

Answer 2

I'm not sure this is what you want, but the following link is a 'top' version of BottomSheetBehavior.

https://github.com/ipuris/AndroidTopSheet/blob/master/library/src/main/java/com/github/techisfun/android/topsheet/TopSheetBehavior.java

Full code including example app: https://github.com/ipuris/AndroidTopSheet

Include the TopSheetBehavior class to your project, then you can use it by changing the app:layout_behavior value to TopSheetBehavior instead of android.support.design.widget.BottomSheetBehavior.

Above code is forked from the original repository, but I fixed some library dependencies (old android.support library -> androidx library) for latest version of Android.

(Maybe this answer is too late for @jernkuan, but I hope this answer can be helpful other developers.)
