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。

Add

android:descendantFocusability="blocksDescendants"

在你的子SrollView或NestedScrollView(和父ListView, recyclerview和gridview任意一个)

对于谁想要的只是防止用户滚动RecyclerView，而不松散smoothscrolltopposition或任何其他“去位置”方法，我建议宁愿扩展RecyclerView类，覆盖 onTouchEvent。是这样的:

            public class HardwareButtonsRecyclerView extends RecyclerView {
            
                    public HardwareButtonsRecyclerView(@NonNull Context context) {
                        super(context);
                    }
            
                    public HardwareButtonsRecyclerView(@NonNull Context context, @Nullable AttributeSet attrs) {
                        super(context, attrs);
                    }
            
                    public HardwareButtonsRecyclerView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
                        super(context, attrs, defStyleAttr);
                    }
            
                @Override
                public boolean onTouchEvent(MotionEvent e) {
                    return false;
                }
            }

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)

recyclerView.addOnItemTouchListener(new RecyclerView.SimpleOnItemTouchListener() {
        @Override
        public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
            // Stop only scrolling.
            return rv.getScrollState() == RecyclerView.SCROLL_STATE_DRAGGING;
        }
    });
