cardview onTouch监听器冲突/灵敏度中的android listview

Question

这是一个显示问题保管箱链接的测试项目: https://www.dropbox.com/sh/8s3v9ydcj6jvpl8/AACZ2VRP2N9R1ec7pxrsAn0ga?dl=0

这是我在这里回答的问题的延续，但现在我要问的是 onTouch 的敏感性/冲突: Android CardView with ListView inside - onTouchListener on CardView not working

我有一个卡片 View ，里面有一个 ListView 。我也需要滚动并单击 ListView 中的项目才能工作，我也希望能够使用 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。

我已经能够让类似的东西在 iOS 上完美运行，因此在 Android 上也应该可行。

                    return true;
                } else {
                    checkIfPanning=false;
                    if(mylistview!=null){
                        //Route all touch event to listview without logic
                        System.out.println("BBBBB Touched list");
                        mylistview.onTouchEvent(event);
                        return true;
                    }
                }
                return true;
            }


        };

        mycardview.setOnTouchListener(onTouchListener);

    }
}

cardview onTouch 监听器和 listview 现在都检测到触摸。但是，当我尝试移动卡片 View 时， ListView 一直在尝试滚动。当我尝试在列表上滚动时，卡片反而移动了。

我明白为什么会这样。基本上，onTouch 监听器似乎将 cardview 移动与 listview 滚动相冲突，但我不确定如何在代码中弄清楚我是在尝试滚动还是移动 cardview。

    public CustomCardView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomCardView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        /*
        * This method determines whether we want to intercept the motion.
        * If we return true, onTouchEvent will be called.
        */
        System.out.println("Touched custom from card");
        return true;
    }
}

请大家帮忙推荐试试!谢谢!

编辑:这是一段视频，介绍它在 iOS 上的工作原理。我可以在 ListView 上滚动。向左或向右平移会使卡片移动。 https://www.dropbox.com/s/5dm52vtjb1xgcl5/iOS.mov?dl=0

卡片 View 不会滚动，只有卡片 View (即 ListView )内的内容会滚动。卡片 View 只能通过跟踪手指来回移动。想象一下 tinder，您可以在其中刷卡并在卡内滚动。

Answer 1

经过 2 周的试验，我自己解决了这个问题。

我从卡片 View 中删除了 onInterceptTouchEvent 和 ontouch。相反，创建一个自定义 OnTouchListener 并将其附加到 ListView 本身。然后在自定义的 OnTouchListener 中，尝试找出触摸发生的角度。如果角度在特定范围内，则向上或向下滚动。其他明智的左/右滑动。我仍在尝试校准角度，以确定哪个角度最适合可用性，但这似乎工作得很好。

我从这个链接中得到了一些计算角度的帮助: How to detect swipe direction between left/right and up/down
