androidviewviewview里面的cardview onTouch监听器冲突/敏感

这是一个测试项目,显示问题的Dropbox链接:https://www.dropbox.com/sh/8s3v9ydcj6jvpl8/AACZ2VRP2N9R1ec7pxrsAn0ga?dl=0

这是我在这里已经回答的问题的延续,但现在我问的是onTouch的敏感性/冲突:Android CardView和ListView里面 - CardView上的onTouchListener无法正常工作

我有一个listview里面的cardview。 我需要在列表视图中滚动并单击项目才能工作,并且我希望能够使用ontouchlistener移动整个cardview。 我在cardview上设置了一个onTouchListener,但它不能正常工作,因为listview滚动与cardview移动冲突。

我已经能够获得类似的东西在iOS上工作,所以应该可以在android上操作。

    }
}

cardview onTouch监听器和列表视图现在都可以检测到触摸。 但是,当我尝试移动卡片视图时,listview不断尝试滚动。 当我尝试在列表中滚动时,卡片移动intead。

我明白为什么会发生这种情况。 基本上,onTouch监听器似乎与使用listview滚动的cardview运动冲突,但我不知道如何在代码中弄清楚我是否试图滚动或移动卡片视图。

请帮助建议尝试! 谢谢!

编辑:这是一个关于它如何在iOS上运行的视频。 我可以在列表视图上滚动。 平移向左或向右使卡片移动。 https://www.dropbox.com/s/5dm52vtjb1xgcl5/iOS.mov?dl=0

cardview不会滚动,只有cardview内的内容(这是listview)会滚动。 卡片视图只能通过跟踪手指来移动。 想象一下,在卡片可以被刷卡的情况下,你可以滚动。


经过2周的实验后,我能够自己解决这个问题。

我从cardview中删除了onInterceptTouchEvent和ontouch。 相反,创建一个自定义的OnTouchListener并将其附加到列表视图本身。 然后在自定义的OnTouchListener中,尝试找出触摸的角度。 如果角度在特定范围内,则上下滚动。 其他明智的左/右滑动。 角度我仍然试图找出哪一个是最好的适用性明智,但这似乎运作良好。

我从这个链接计算角度得到了一些帮助:如何检测左/右和上/下之间的滑动方向

CardView越来越受关注,所以尝试在卡片视图中添加android:descendantFocusability="blocksDescendants" ,就像

 <com.pranapps.testontouch.CustomCardView

android:layout_gravity="center"
android:layout_width="match_parent"

android:descendantFocusability="blocksDescendants"> //here your listview </com.pranapps.testontouch.CustomCardView>
