Known Direct Subclasses ComposeView ComposeView A android.view.View that can host Jetpack Compose UI content.

Base class for custom android.view.Views implemented using Jetpack Compose UI. Subclasses should implement the Content function with the appropriate content. Calls to addView and its variants and overloads will fail with IllegalStateException.

This android.view.View requires that the window it is attached to contains a ViewTreeLifecycleOwner. This androidx.lifecycle.LifecycleOwner is used to dispose of the underlying composition when the host Lifecycle is destroyed, permitting the view to be attached and detached repeatedly while preserving the composition. Call disposeComposition to dispose of the underlying composition earlier, or if the view is never initially attached to a window. (The requirement to dispose of the composition explicitly in the event that the view is never (re)attached is temporary.)
