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。

这对我来说很管用:

  recyclerView.setOnTouchListener(new View.OnTouchListener() {
      @Override
      public boolean onTouch(View v, MotionEvent event) {
          return true;
      }
  });

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)

遇到了包含多个RecycleView的片段，所以我只需要一个滚动条，而不是每个RecycleView中的一个滚动条。

所以我只是把ScrollView放在父容器中，其中包含2个RecycleViews，并使用android:isScrollContainer="false"在RecycleView

<android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layoutManager="LinearLayoutManager"
    android:isScrollContainer="false" />

答案很简单。

LinearLayoutManager lm = new LinearLayoutManager(getContext()) {
                @Override
                public boolean canScrollVertically() {
                    return false;
                }
            };

上面的代码禁用了RecyclerView的垂直滚动。

真正的答案是

recyclerView.setNestedScrollingEnabled(false);
