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。

重写onTouchEvent()和onInterceptTouchEvent()并返回false，如果你根本不需要OnItemTouchListener。 这不会禁用ViewHolders的OnClickListeners。

public class ScrollDisabledRecyclerView extends RecyclerView {
    public ScrollDisabledRecyclerView(Context context) {
        super(context);
    }

    public ScrollDisabledRecyclerView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public ScrollDisabledRecyclerView(Context context, @Nullable AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent e) {
        return false;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e) {
        return false;
    }
}

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)

在新版本的android和api中进行了多次尝试后，这种方法对我来说很有效。

Kotlin的新答案

创建一个名为ScrollDisabledRecyclerView的类，并放入如下代码:

class ScrollDisabledRecyclerView : RecyclerView { constructor(context: Context?) : super(context!!) constructor(context: Context?, @Nullable attrs: AttributeSet?) : super(context!!, attrs) constructor(context: Context?, @Nullable attrs: AttributeSet?, defStyle: Int) : super( context!!, attrs, defStyle ) override fun onTouchEvent(e: MotionEvent): Boolean { return e.action == MotionEvent.ACTION_MOVE } override fun onInterceptTouchEvent(e: MotionEvent): Boolean { return false } }

在你的XML中使用这个类而不是RecyclerView(这个类是从它扩展来的):

<info.sanaebadi.ScrollDisabledRecyclerView android:id="@+id/recyclerView" android:layout_width="0dp" android:layout_height="0dp" android:layout_marginStart="8dp" android:layout_marginTop="8dp" android:layout_marginEnd="8dp" android:layout_marginBottom="8dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" android:clipToPadding="true" tools:listitem="@layout/multiple_questions_row" />

最后，使用mainactivity中的按钮处理next和previous，如下所示:

注意:我正在使用视图绑定

binding.buttonNextQuestion.setOnClickListener {
            val totalItemCount: Int = binding.recyclerView.adapter!!.itemCount
            if (totalItemCount <= 0) return@setOnClickListener
            val lastVisibleItemIndex: Int = linearLayoutManager.findLastVisibleItemPosition()
            if (lastVisibleItemIndex >= totalItemCount) return@setOnClickListener
            linearLayoutManager.smoothScrollToPosition(
                binding.recyclerView,
                null,
                lastVisibleItemIndex + 1
            )

        }
        binding.buttonPreviousQuestion.setOnClickListener {
            val firstVisibleItemIndex: Int =
                linearLayoutManager.findFirstCompletelyVisibleItemPosition()
            if (firstVisibleItemIndex > 0) {
                linearLayoutManager.smoothScrollToPosition(
                    binding.recyclerView,
                    null,
                    firstVisibleItemIndex - 1
                )
            }
        }

你可以通过冻结RecyclerView来禁用滚动。

冻结: recyclerView.setLayoutFrozen(真正的)

解冻:recyclerView.setLayoutFrozen(false)

这是一个有点笨拙的方法，但它是有效的;你可以在RecyclerView中启用/禁用滚动。

这是一个空的RecyclerView。OnItemTouchListener窃取每个触摸事件，从而禁用目标RecyclerView。

public class RecyclerViewDisabler implements RecyclerView.OnItemTouchListener {

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
        return true;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

使用它:

RecyclerView rv = ...
RecyclerView.OnItemTouchListener disabler = new RecyclerViewDisabler();

rv.addOnItemTouchListener(disabler);        // disables scolling
// do stuff while scrolling is disabled
rv.removeOnItemTouchListener(disabler);     // scrolling is enabled again
