我有一个YoutubePlayer播放一个视频在我的运动布局。我想实现这个youtube-like motion https://developer.android.com/training/constraint-layout/motionlayout/examples#youtube-like_motion
这里的问题是,在上面提供的示例中,它们使用ImageView而不是YoutubePlayer接口来完成动画。但不幸的是,youtube播放器界面似乎“覆盖”点击监听器,只允许点击,而不是滑动。(这是我的推论)。
我想知道它是如何在youtube应用程序中实现的。如果有人能回答我,请回答。我在我的应用程序中需要这个。
我提出了一个问题,请看一下。https://issuetracker.google.com/issues/162155197
这就是我尝试过的:
当
touchRegionId设置为youtube播放器前面或后面的视图时,对界面的单击完全被禁用。但是动画作品。我看不到这个选项的解决方案,因为我认为这种行为是故意的。当
limitBoundsTo设置为视图时,它就完成了它的工作。它将OnSwipe操作区域限制在这样的视图边界上。这正是我需要的工作方式,直到YOUTUBE播放器界面初始化为止。在初始化之后,OnSwipe就不再被检测到,接口只监听单击,例如,这使您能够暂停视频。如果一定要查看的限制大于youtube界面,我可以对视图的剩余部分进行滑动。但youtube的界面不听刷卡。也许这个接口不支持考虑到2和3,我认为这是接口本身的问题。不管你有什么建议,请告诉我。谢谢。

这是一个复杂的运动布局场景的问题。要在相同的转换中使用onClick和onSwipe,您需要:
子类的onClick
class MyMotionLayout @JvmOverloads constructor(context: Context):MotionLayout(context) {
override fun onInterceptTouchEvent(ev: MotionEvent): Boolean {
//Check if we have MotionEvent.ACTION_UP while MotionEvent.ACTION_MOVE<0.5
// i.e ..this was a click
if(ev==MotionEvent.ACTION_UP){
return true
}
return false
}
override fun onTouchEvent(event: MotionEvent): Boolean {
// Here we actually handle the touch event
// This method will only be called if the touch event was intercepted in
// onInterceptTouchEvent
callOnClick()
}
