android - Horizo​​ntalScrollView 与 Recyclerview 滑动 android 冲突

Question

我正在使用回收器 View 滑动来关闭，我的卡片 View 或回收器项目包含水平 ScrollView 。每次触摸都会优先选择滑动以关闭。这是我的代码...请告诉我如何分开两次滑动？

<android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"

Answer 1

在代码中，您必须将 OnTouchListener 添加到 Horizo​​ntalScrollView。然后，当它接收到 ACTION_MOVE 事件时，您可以禁止父 View (在本例中为 RecyclerView)将水平滚动移动捕获为滑动:

HorizontalScrollView hScroll = [findViewById or whatever];
hScroll.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_MOVE) {
            // Disallow the touch request for parent scroll on touch of child view
            v.getParent().requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }
});

请注意，如果您的 Horizo​​ntalScrollView 的内容没有填满整个单元格宽度(因此不会激活水平滚动)，您可能不想禁止滑动.您可以通过使用检查宽度条件的 bool 值更改 true 来解决此问题，例如:

horizontalScrollContents.measure(0, 0);
boolean lockSwipe = horizontalScrollContents.getMeasuredWidth() > cellWidth;
...
v.getParent().requestDisallowInterceptTouchEvent(lockSwipe);
