如何在Android的回收器视图中滚动到特定位置（不在视图中）的项目？

Question

I have a list of images in a recycler view with a Horizontal Linear Layout. I want to programmatically scroll to say position = 20, while the image at that position is not in view. I have tried using:

recyclerView.scrollToPosition(position);

but this only scrolls if the item is in view. I have also tried using smoothScrollBy(x,y) and getLayoutManager().scrollToPosition(position) but it doesn't work.

Answer 1

使用以下代码：

yourRecyclerViewObject.getLayoutManager().scrollToPosition(itemPosition);

Answer 2

I had this same issue and using delay worked for me

recyclerView.postDelayed(new Runnable(){
   @Override
   public void run(){
      recyclerView.scrollToPosition(position);
   }
},300);
