Android Recycler view disable the scrollbar but not use setVerticalScrollBarEnabled

I have a view pager and have 3 fragments. These 3 fragments are recycler view.

I would like to when I drag to the next page, the scroll bar will be disappeared. But I don't want to use setVerticalScrollBarEnabled. Because when called this method, the main content items will be scaled up. I think the reason is the scroll bar width is 4dp. So the main content items will be scaled up. I don't like this scale up effect.

I also tried setVerticalScrollbarThumbDrawable with transparent colour. But this method need to add this condition Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q.

Anybody can give me some suggestions. Thanks a lot.

public void SetRecyclerViewScrollBar(boolean enable) {
        if(this.mRecyclerView != null) {
            this.mAdapter.notifyDataSetChanged();
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                if(!enable) {
                    this.mRecyclerView.setVerticalScrollbarThumbDrawable(this.mContext.getDrawable(R.drawable.scrollbar_transparent));
                    this.mRecyclerView.setVerticalScrollbarTrackDrawable(this.mContext.getDrawable(R.drawable.vertical_scrollview_track_transparent));
                } else {
                    this.mRecyclerView.setVerticalScrollbarThumbDrawable(this.mContext.getDrawable(R.drawable.scrollbar));
                    this.mRecyclerView.setVerticalScrollbarTrackDrawable(this.mContext.getDrawable(R.drawable.vertical_scrollview_track));
                }
            }
        }
    }

make some semi transparent scroll thumb drawable and add this:

android:scrollbarStyle="insideOverlay"

or Java/Kotlin side:

scrollableView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

this will make your thumb won't take space and will be drawn on top of your list/content. check out this pic how different styles behaves. and then you may use setVerticalScrollBarEnabled, space for your content (whole screen width) won't change and won't be redrawn (thus scaled up)

Try use this in your layout file.

android:scrollbars="none"

It should be like this.

 <android.support.v7.widget.RecyclerView
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:scrollbars="none"
     ...
