推荐答案

您必须为此使用LayoutManager.请执行以下步骤.

You have to make use of LayoutManager for that. Follow the below steps.

1).首先，在Activity/Fragment中声明LayoutManager.例如，我采用了LinearLayoutManager

1). First of all, declare LayoutManager in your Activity/Fragment. For example, I have taken LinearLayoutManager

private LinearLayoutManager mLinearLayoutManager;

2).初始化LinearLayoutManager并将其设置为您的RecyclerView

2). Initialise the LinearLayoutManager and set that to your RecyclerView

mLinearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLinearLayoutManager);

3).在Button onClick上，执行此操作以滚动到RecyclerView的底部.

3). On your Button onClick, do this to scroll to the bottom of your RecyclerView.

mLinearLayoutManager.scrollToPosition(yourList.size() - 1); // yourList is the ArrayList that you are passing to your RecyclerView Adapter.
