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

你得利用LayoutManager。遵循以下步骤。

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

1).首先，在您的活动/片段中声明LayoutManager。例如，我选择了LinearLayoutManager

private LinearLayoutManager mLinearLayoutManager;

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

2).初始化LinearLayoutManager，并将其设置为可回收视图

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

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

3).在onClick按钮上，这样做可以滚动到回收视图的底部。

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

Hope this will help..!!

You can use scrollToPosition() with the index of the last position.

您可以使用scrollToPosition()和上一个位置的索引。
