FlowOnHierarchyChangeListener

class FlowOnHierarchyChangeListener(recursive: Boolean = false, _onChildViewAdded: MutableSharedFlow<Pair<View, View>> = MutableSharedFlow(extraBufferCapacity = Int.MAX_VALUE), _onChildViewRemoved: MutableSharedFlow<Pair<View, View>> = MutableSharedFlow(extraBufferCapacity = Int.MAX_VALUE)) : ViewGroup.OnHierarchyChangeListener(source)

kotlinx.coroutines.flow.Flow-based android.view.ViewGroup.OnHierarchyChangeListener

Parameters

recursive

If set, any call of onChildViewAdded will check if child View is ViewGroup and subscribe to this ViewGroup too

Internal MutableSharedFlow which will be used to pass data to onChildViewAdded flow

_onChildViewRemoved

Internal MutableSharedFlow which will be used to pass data to onChildViewRemoved flow

Constructors

FlowOnHierarchyChangeListener

constructor(recursive: Boolean = false, _onChildViewAdded: MutableSharedFlow<Pair<View, View>> = MutableSharedFlow(extraBufferCapacity = Int.MAX_VALUE), _onChildViewRemoved: MutableSharedFlow<Pair<View, View>> = MutableSharedFlow(extraBufferCapacity = Int.MAX_VALUE))

Properties

onChildViewAdded

val onChildViewAdded: SharedFlow<Pair<View, View>>

onChildViewRemoved

val onChildViewRemoved: SharedFlow<Pair<View, View>>

Functions

onChildViewAdded

open override fun onChildViewAdded(parent: View, child: View)

Will emit data into onChildViewAdded flow. If recursive is true and child is ViewGroup will also subscribe to child hierarchy changes.

onChildViewRemoved

open override fun onChildViewRemoved(parent: View, child: View)
