ComposeView

Class

Android
class ComposeView
@JvmOverloads
constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
    AbstractComposeView(context, attrs, defStyleAttr)

A android.view.View that can host Jetpack Compose UI content. Use setContent to supply the content composable function for the view.

By default, the composition is disposed according to ViewCompositionStrategy.Default. 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.)

ComposeView only supports being added into view hierarchies propagating LifecycleOwner and SavedStateRegistryOwner via androidx.lifecycle.setViewTreeLifecycleOwner and androidx.savedstate.setViewTreeSavedStateRegistryOwner. In most cases you will already have it set up correctly as androidx.activity.ComponentActivity, androidx.fragment.app.Fragment and androidx.navigation.NavController will provide the correct values.

Functions

fun setContent(content: @Composable () -> Unit)

Set the Jetpack Compose UI content for this view. Initial composition will occur when the view becomes attached to a window or when createComposition is called, whichever comes first.
