android - ScrollView 在水平滑动行时垂直移动

Question

我在 ScrollView 中有很多自定义 View 。我在 customview 上实现了滑动功能。当我向左滑动自定义 View 时， ScrollView 也会垂直移动。我不想在滑动时垂直移动 ScrollView 。我认为 Action_Cancel 触摸事件将滚动到我必须停止的 View 。我试图阻止它，但它不起作用。下面是

Answer 1

在你的onScroll()

放这个-

ViewParent parent = getParent();
     if(parent!= null){
     parent.requestDisallowOnInterceptTouchEvent(true);
}
