我有一个类似YouTube视频播放器的视图,在该视图中有一个列表,单击后可在下一个屏幕中播放视频。
我已将Motionscene添加到视频视图,因此在向下拖动时,视频视图会变小。但是这样做时,onClick或onTouch事件不适用于播放/暂停控件。
在youtube中,我们都可以正常工作。所以我想知道我哪里出错了。

我偶然发现了类似的问题。我最终将OnTouchListener
设置为Motionlayout
。
motionLayout.setOnTouchListener { _, event ->
if (event.action != MotionEvent.ACTION_UP) return@setOnTouchListener false
val isTouchingPlayButton = Rect().also { playButton.getHitRect(it) }
.contains(event.x.toInt(), event.y.toInt())
if (isTouchingPlayButton && motionLayout.progress == 0f) {
player.play()
return@setOnTouchListener true
}
false
}
