Question

I want to create 2 horizontal listview one below the other. I dont want the listview to scroll seperatley, when the user swipes the screen both the lists should get scrolled .

I created 2 horizontal listview as in this project , https://github.com/sephiroth74/HorizontalVariableListView

but both the listview can be scrolled separately. Can anyone help me create it.

THanks in advance.

Answer 1

Try something like

if( this.getScrollY() != otherList.getScrollY() )
    otherList.setScrollY( this.getScrollY() );

In the onScroll method of the onScrollListener. The above is pretty rough.

You can do it this way:

• Define you own RecyclerView.OnScrollListener class.
• For each RecyclerView, add your scroll listener using addOnScrollListener (RecyclerView.OnScrollListener listener)
• In your Ativity/Fragment, listen to your scroll listener onScrolled method using the observer pattern.
• When one Recycler view scrolls, you Activity/Framgent iterate your Recycler views and scroll them using scrollTo(int x,int y) method.
