使用 Compose 在 AndroidView 中使用片段时崩溃
Crash when using fragment in AndroidView using compose
我正在尝试使用 compose 并尝试在 compose AndroidView 中包含一个片段。
所以在我的情况下,我们有一个带有 ComposeView 的 AFragment,并且在 ComposeView 内部有一个 AndroidView,它创建一个 FragmentContainerView 并添加一个 PIFragment。
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?
): View {
return ComposeView(requireContext()).apply {
setContent {
AppTheme {
GalleryScreen(
factory = viewModelFactory,
remoteConfig = remoteConfig,
id = id,
currentPosition = currentPositionState,
onBack = { router.back(requireActivity()) },
) {
AndroidView(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight(),
factory = {
FragmentContainerView(context).apply {
id = R.id.pFIC
}
},
update = {
childFragmentManager.beginTransaction().replace(
R.id.pFIC,
PIFragment::class.java,
buildArguments(
id = id,
origin = origin,
), null
).commitAllowingStateLoss()
},
)
}
}
}
}
}
一切正常,但当我们在生产环境中发布这段代码时,我们发现 firebase 崩溃了:
java.lang.IllegalArgumentException: No view found for id 0x7f0b072b (...:id/pFIC) for fragment PIFragment{ef1f89b} (bdbe15f0-679d-41bb-8a27-367655f73545 id=0x7f0b072b)

事实上,崩溃是在重新创建父片段之后发生的。
在我的例子中,因为导航:
- AFragment(带 PIFragment)
- 导航到 BFragment
- 返回 AFragment
崩溃,因为片段管理器正在尝试重新创建 AFragment 和 PIFragment,但是组合传递尚未完成,因此 pFIC 尚不存在。
解决方案是在销毁父片段视图时删除 PIFragment。
override fun onDestroyView() {
childFragmentManager.findFragmentById(R.id.pFIC)?.let { fragment ->
childFragmentManager.beginTransaction().remove(fragment).commitAllowingStateLoss()
}
super.onDestroyView()
}
