实现思路：设置滑动监听，滑动左边recycler，右侧recycler跟着移动相应距离即可(注意：条目高度要相等，如果添加分割线，注意分割线高度)
private void syncScroll(RecyclerView leftList, RecyclerView rightList) {
leftList.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {
// note: scrollBy() not trigger OnScrollListener
// This is a known issue. It is caused by the fact that RecyclerView does not know how LayoutManager will handle the scroll or if it will handle it at all.
rightList.scrollBy(dx, dy);
}
}
});
rightList.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {
leftList.scrollBy(dx, dy);
}
}
});
}
