Two Scrolls monitor each other's sliding - stuck problem

①Finger slide Scroll1

②Trigger onScroll of Scroll1

③Call scroller2.scrollBy to slide Scroll2

④Trigger onScroll of Scroll2

⑤Call scroller1.scrollBy to slide Scroll1

Here ⑤ will trigger ②, which will keep looping, causing the stack to burst, which is the error you posted above [Error message: Stack overflow!]

So add a flag:

flag=true means that the finger is sliding Scroll1, and there is no need to use scroller1.scrollBy to slide Scroll1;

flag=false means that the finger is sliding Scroll2, and there is no need to use scroller2.scrollBy to slide Scroll2;

Changing the name of this flag to isTouchScroll1OrScroll2 will be more intuitive.

scroller1: Scroller = new Scroller()
scroller2
