Jetpack Compose with WindowManager - 无法在分离视图上启动此动画器

Question

我目前正在开发一个名为 Floating-Bubble-View 的 Android 库，该库有助于在屏幕上创建浮动视图。最近，我添加了对

Composable

的支持，并且在自定义

LifecycleOwner

的帮助下，我可以毫无问题地显示/删除可组合项。但是，当滚动 LazyColumn 时，如果我在动画停止之前调用

removeView

，应用程序开始崩溃。这是错误信息：

Process: com.torrydo.testfloatingbubble, PID: 29264
java.lang.IllegalStateException: Cannot start this animator on a detached view!

这是删除功能

fun remove() {
     builder.composeView?.also { composeView ->
        builder.composeLifecycleOwner?.onPause()
        builder.composeLifecycleOwner?.onStop()
        windowManager!!.removeView(composeView)
     }
}

基本可组合项，带有一个返回屏幕的按钮，以及一个

LazyColumn

Answer 1

感谢 Lan Lake 的建议，目前是 Google 的 Android SE。我意识到我在删除

onDestroy()

时没有打电话给

ComposeView

。结果，

composable

没有触发

disposal

。这是更新的代码片段。

builder.composeView?.also {
       builder.composeLifecycleOwner?.onPause()
       builder.composeLifecycleOwner?.onStop()
       builder.composeLifecycleOwner?.onDestroy() // added
       super.remove(it)
}
