Question

我在动作布局中有一个水平的回收站视图。有时，当我进行水平滑动时，页面开始沿垂直方向滚动。当我们进行对角猛击时会发生这种情况。

我想要类似Google Play的工具，其中水平的回收站视图可以抵御稍微倾斜的垂直滑动。 BTW设置nestedscrollEnabled不起作用。

关于所有RecycleView滚动行为和问题本身，有一篇不错的文章。结帐RúbenSousa article。解决方案非常简单，请尝试使用采用的RecyclerView：

/**
 * A RecyclerView that only handles scroll events with the same orientation of its LayoutManager.
 * Avoids situations where nested recyclerviews don't receive touch events properly:
 */
public class OrientationAwareRecyclerView extends RecyclerView {

    private float lastX = 0.0f;
    private float lastY = 0.0f;
    private boolean scrolling = false;

    public OrientationAwareRecyclerView(@NonNull Context context) {
        this(context, null);
    }

    public OrientationAwareRecyclerView(@NonNull Context context, @Nullable AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public OrientationAwareRecyclerView(@NonNull Context context, @Nullable AttributeSet attrs,
                                        int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        addOnScrollListener(new OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                scrolling = newState != RecyclerView.SCROLL_STATE_IDLE;
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent e) {
        final LayoutManager lm = getLayoutManager();
        if (lm == null) {
            return super.onInterceptTouchEvent(e);
        }

        boolean allowScroll = true;

        switch (e.getActionMasked()) {
            case MotionEvent.ACTION_DOWN: {
                lastX = e.getX();
                lastY = e.getY();
                // If we were scrolling, stop now by faking a touch release
                if (scrolling) {
                    MotionEvent newEvent = MotionEvent.obtain(e);
                    newEvent.setAction(MotionEvent.ACTION_UP);
                    return super.onInterceptTouchEvent(newEvent);
                }
                break;
            }
            case MotionEvent.ACTION_MOVE: {
                // We're moving, so check if we're trying
                // to scroll vertically or horizontally so we don't intercept the wrong event.
                float currentX = e.getX();
                float currentY = e.getY();
                float dx = Math.abs(currentX - lastX);
                float dy = Math.abs(currentY - lastY);
                allowScroll = dy > dx ? lm.canScrollVertically() : lm.canScrollHorizontally();
                break;
            }
        }

        if (!allowScroll) {
            return false;
        }

        return super.onInterceptTouchEvent(e);
    }
}

尝试一下：

    RecyclerView rv = findViewById(R.id.recycler_view); 
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, true);
        rv.setLayoutManager(layoutManager); 
        rv.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    int action = event.getAction();
                    switch (action) {
                    case MotionEvent.ACTION_DOWN:
                        // Disallow RecyclerView to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(true);
                        break;

                    case MotionEvent.ACTION_UP:
                        // Allow RecyclerView to intercept touch events.
                        v.getParent().requestDisallowInterceptTouchEvent(false);
                        break;
                    }

                    v.onTouchEvent(event);
                    return true;
                }
            });

当您使用水平recyclerview滚动时，该代码可防止垂直滚动。
