Scrolling down view pager is scrolling the bottomsheet as well, how ? about custombottomsheetbehavior

Hi @gmeral, that question can be answered by @akaN44, he improved that part of the project.
Like I said in others threads before, I will be working hard in this project asap, after finishing some functional requirements of an app.

Okay thank you, let's hope he is going to be passing by sometime soon then :)

@gmeral Take a look at this commit b66ef17

[gmeral]

Oh i see, it's very clear now, then you added an if to only have this behaviour in STATE_ANCHOR_POINT.
Thanks a lot, i integrated these changes and it works like a charm.

I am also curious, as the ViewPager disable the horizontal scroll for the Map behind, which looks like a dirty hack.
As soon as we replace the ViewPager with an ImageView, the map can now move...
Commit referenced by @akaN44 is now overwritten ...

In BottomSheetBehaviorGoogleMapsLike.java :
In the onInterceptTouchEvent method you have to replace this piece of code :

View scroll = mNestedScrollingChildRef.get();
if (scroll != null && parent.isPointInChildBounds(scroll, initialX, mInitialY)) {
    mActivePointerId = event.getPointerId(event.getActionIndex());
    mTouchingScrollingChild = true;
}

by

if(mState == STATE_ANCHOR_POINT){
            mActivePointerId = event.getPointerId(event.getActionIndex());
            mTouchingScrollingChild = true;
        }else {
            View scroll = mNestedScrollingChildRef.get();
            if (scroll != null && parent.isPointInChildBounds(scroll, initialX, mInitialY)) {
                mActivePointerId = event.getPointerId(event.getActionIndex());
                mTouchingScrollingChild = true;
            }
        }
