我的布局看起来像这样：
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout

<include

</android.support.constraint.ConstraintLayout>
FlipView 是一个自定义的Framelayout，它具有像书本一样的翻页动画。用户还可以在每页传播上捏缩放。
下面的工具栏有一系列蜡笔。用户点击颜色后，会启动一个不可见的片段，用户可以在页面上展开。
这是工具栏布局

工具栏最初以不可见的方式开始。如果单击页面上的任何位置，它应从底部滑出。我可以使用dispatchTouchEvent
捕获click事件override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
if (ev!!.action == MotionEvent.ACTION_DOWN) {
startX = ev.x
startY = ev.y
}
if (ev.action == MotionEvent.ACTION_UP){
val endX = ev.x
val endY = ev.y
if (isAClick(startX, endX, startY, endY)) {
onSlideViewButtonClick(reading_toolbar!!)
return true
} else {
return super.dispatchTouchEvent(ev)
}
}
return super.dispatchTouchEvent(ev)
}
因此工具栏滑出，但如果我点击工具栏上的任何蜡笔，它会向下滑动，这是不应该做的。基本上，我想要的是，如果用户点击工具栏本身的其他任何地方，那么它应该向下滑动。
我尝试使用onTouch，因此我可以传递视图而不是dispatchTouchEvent，但即使使用相同的逻辑，我也无法捕获点击。不过，我可以捕捉拖拽事件。
class ReadActivity : Activity(), FlipViewAdapter.Callback, FlipView.OnFlipListener, FlipView.OnOverFlipListener, View.OnTouchListener {
...
}
设置
flip_view.setOnTouchListener(this)
测试点击此处
override fun onTouch(v: View?, ev: MotionEvent?): Boolean {
println("clicking")
// put actual clicking logic
return true
}
