XML格式:-

你可以添加

android：nestedScrollingEnabled=“false”

在子RecyclerView布局XML文件中

or

在爪哇:-

childRecyclerView.setNestedScrollingEnabled(假);

Java代码中的RecyclerView。

使用ViewCompat (Java):-

childRecyclerView.setNestedScrollingEnabled(假);将只在android_version>21设备上工作。要在所有设备上工作，请使用以下方法

ViewCompat。setNestedScrollingEnabled (childRecyclerView假);

真正的答案是

recyclerView.setNestedScrollingEnabled(false);

扩展LayoutManager并覆盖canscrollhorizontal()和canscrollvertical()来禁用滚动。

注意，在开头插入项目不会自动回滚到开头，为了解决这个问题，可以这样做:

  private void clampRecyclerViewScroll(final RecyclerView recyclerView)
  {
    recyclerView.getAdapter().registerAdapterDataObserver(new RecyclerView.AdapterDataObserver()
    {
      @Override
      public void onItemRangeInserted(int positionStart, int itemCount)
      {
        super.onItemRangeInserted(positionStart, itemCount);
        // maintain scroll position at top
        if (positionStart == 0)
        {
          RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
          if (layoutManager instanceof GridLayoutManager)
          {
            ((GridLayoutManager) layoutManager).scrollToPositionWithOffset(0, 0);
          }else if(layoutManager instanceof LinearLayoutManager)
          {
            ((LinearLayoutManager) layoutManager).scrollToPositionWithOffset(0, 0);
          }
        }
      }
    });
  }

在Kotlin中，如果你不想为了设置一个值而创建一个额外的类，你可以从LayoutManager创建匿名类:

recyclerView.layoutManager = object : LinearLayoutManager(context) {
    override fun canScrollVertically(): Boolean = false
}

有一种使用标准功能禁用滚动的更直接的方法(从技术上讲，它更确切地说是拦截滚动事件，并在满足条件时结束它)。RecyclerView有一个方法叫做addOnScrollListener(OnScrollListener监听器)，使用这个你可以停止滚动，就像这样:

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
        super.onScrollStateChanged(recyclerView, newState);
        if (viewModel.isItemSelected) {
            recyclerView.stopScroll();
        }
    }
});

Use case: Let's say that you want to disable scrolling when you click on one of the items within RecyclerView so you could perform some actions with it, without being distracted by accidentally scrolling to another item, and when you are done with it, just click on the item again to enable scrolling. For that, you would want to attach OnClickListener to every item within RecyclerView, so when you click on an item, it would toggle isItemSelected from false to true. This way when you try to scroll, RecyclerView will automatically call method onScrollStateChanged and since isItemSelected set to true, it will stop immediately, before RecyclerView got the chance, well... to scroll.

注意:为了更好的可用性，尝试使用GestureListener而不是OnClickListener来防止意外点击。

由于setLayoutFrozen已弃用，你可以通过使用suppressLayout冻结你的RecyclerView来禁用滚动。

冻结:

recyclerView.suppressLayout(true)

解冻:

recyclerView.suppressLayout(false)
