java.lang.IllegalStateException：在 DecorView@5ab7e30[MainActivity] 中找不到 ViewTreeLifecycleOwner

Question

我按照 this 文档将 ComposeView 直接包含在片段中 而没有 xml 布局膨胀 ，但它给出 java.lang.IllegalStateException.

请帮我解决这个问题。

Android 工作室：2020.3.1 金丝雀 14

compose_version:'1.0.0-beta01'

这是片段的代码：

class RecipeListFragment : Fragment() {

private lateinit var viewModel: RecipeListViewModel

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View {
    return ComposeView(requireContext()).apply {
        setContent {
            Column(
                modifier = Modifier
                    .padding(16.dp)
            ) {
                Text(
                    text = "Recipe List",
                    style = MaterialTheme.typography.h3
                )
            }
        }
    }

}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    viewModel = ViewModelProvider(this).get(RecipeListViewModel::class.java)
}

}

这是运行时间错误：

Answer 1

在 AppCompat 1.3.0 版本中引入了对 ViewTreeLifecycleOwner 的支持。

目前最新的 AppCompat 版本是

implementation 'androidx.appcompat:appcompat:1.3.0'

java.lang.IllegalStateException：在 DecorView@5ab7e30[MainActivity] 中找不到 ViewTreeLifecycleOwner
