MediaRouteButton

Kotlin |Java

open class MediaRouteButton : View

kotlin.Any
↳	android.view.View
	↳	androidx.mediarouter.app.MediaRouteButton

The media route button allows the user to select routes and to control the currently selected route.

The application must specify the kinds of routes that the user should be allowed to select by specifying a selector with the setRouteSelector method.

When the default route is selected or when the currently selected route does not match the selector, the button will appear in an inactive state indicating that the application is not connected to a route of the kind that it wants to use. Clicking on the button opens a MediaRouteChooserDialog to allow the user to select a route. If no non-default routes match the selector and it is not possible for an active scan to discover any matching routes, then the button is disabled and cannot be clicked unless setAlwaysVisible is called.

When a non-default route is selected that matches the selector, the button will appear in an active state indicating that the application is connected to a route of the kind that it wants to use. The button may also appear in an intermediary connecting state if the route is in the process of connecting to the destination but has not yet completed doing so. In either case, clicking on the button opens a MediaRouteControllerDialog to allow the user to control or disconnect from the current route.

Prerequisites

To use the media route button, the activity must be a subclass of FragmentActivity from the android.support.v4 support library. Refer to support library documentation for details.

Public methods

enableDynamicGroup

open fun enableDynamicGroup(): Unit

Deprecated: Use with androidx.mediarouter.media.MediaRouterParams#DIALOG_TYPE_DYNAMIC_GROUP instead.

Enables dynamic group feature. With this enabled, a different set of MediaRouteChooserDialog and MediaRouteControllerDialog is shown when the button is clicked. If a media route provider supports dynamic group, the users can use that feature with the dialogs.
