今天使用compose写好ui后，用WindowManager.addView(composeView, lp);。运行发现报错：
java.lang.IllegalStateException: ViewTreeLifecycleOwner not found from androidx.compose.ui.platform.ComposeView
在stackoverflow看到解决方法如下

创建KeyboardViewLifecycleOwner.kt文件

class KeyboardViewLifecycleOwner :
    LifecycleOwner, ViewModelStoreOwner, SavedStateRegistryOwner {

    fun onCreate() {
        savedStateRegistryController.performRestore(null)
        lifecycleRegistry.handleLifecycleEvent(Lifecycle.Event.ON_CREATE)
    }

    fun onResume() {
        lifecycleRegistry.handleLifecycleEvent(Lifecycle.Event.ON_RESUME)
    }

    fun onPause() {
        lifecycleRegistry.handleLifecycleEvent(Lifecycle.Event.ON_PAUSE)
    }

    fun onDestroy() {
        lifecycleRegistry.handleLifecycleEvent(Lifecycle.Event.ON_DESTROY)
        store.clear()
    }

    /**
    Compose uses the Window's decor view to locate the
    Lifecycle/ViewModel/SavedStateRegistry owners.
    Therefore, we need to set this class as the "owner" for the decor view.
     */
    fun attachToDecorView(decorView: View?) {
        if (decorView == null) return

        ViewTreeLifecycleOwner.set(decorView, this)
        ViewTreeViewModelStoreOwner.set(decorView, this)
        ViewTreeSavedStateRegistryOwner.set(decorView, this)
    }

    // LifecycleOwner methods
    private val lifecycleRegistry: LifecycleRegistry = LifecycleRegistry(this)
    override fun getLifecycle(): Lifecycle = lifecycleRegistry

    // ViewModelStore methods
    private val store = ViewModelStore()
    override fun getViewModelStore(): ViewModelStore = store

    // SavedStateRegistry methods
    private val savedStateRegistryController = SavedStateRegistryController.create(this)
    override fun getSavedStateRegistry(): SavedStateRegistry =
        savedStateRegistryController.savedStateRegistry
}

在Activity中使用

class MainActivity : ComponentActivity() {
    
    private val lifecycleOwner = KeyboardViewLifecycleOwner()

    override fun onCreate(savedInstanceState: Bundle?, persistentState: PersistableBundle?) {
        super.onCreate(savedInstanceState, persistentState)
        lifecycleOwner.onCreate()
    }

    override fun onResume() {
        super.onResume()
        lifecycleOwner.onResume()
    }

    override fun onPause() {
        super.onPause()
        lifecycleOwner.onPause()
    }

    override fun onDestroy() {
        super.onDestroy()
        lifecycleOwner.onDestroy()
    }
    
}

在activity加入属性lifecycleOwner并赋值KeyboardViewLifecycleOwner()，然后再对应的activity回调方法中调用lifecycle的方法

最后调用lifecycleOwner的attachToDecorView方法传入composeView即可

val wm = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
val lp = WindowManager.LayoutParams()
wm.addView(composeView, lp)
