The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\nstatic\n\n\ninterface\nCoordinatorLayout.AttachedBehavior\n`\n\n\n`\n\n\n`\n\n|------------------------------------------------------------------|\n| android.support.design.widget.CoordinatorLayout.AttachedBehavior |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nDefines the default attached [CoordinatorLayout.Behavior](/reference/android/support/design/widget/CoordinatorLayout.Behavior) of a [View](https://developer.android.com/reference/android/view/View.html) class\n\nWhen writing a custom view, implement this interface to return the default behavior\nwhen used as a direct child of an [CoordinatorLayout](/reference/android/support/design/widget/CoordinatorLayout).
