VolumeCallback
public VolumeCallback ()
Public methods
public abstract void onVolumeSetRequest (MediaRouter.RouteInfo info,
int volume)
Called when the volume for the route should be set to the given value
| Parameters |
|---|
info |
MediaRouter.RouteInfo: the route affected by this event |
volume |
int: an integer indicating the new volume value that should be used, always
between 0 and the value set by UserRouteInfo.setVolumeMax(int). |
public abstract void onVolumeUpdateRequest (MediaRouter.RouteInfo info,
int direction)
Called when the volume for the route should be increased or decreased.
| Parameters |
|---|
info |
MediaRouter.RouteInfo: the route affected by this event |
direction |
int: an integer indicating whether the volume is to be increased
(positive value) or decreased (negative value).
For bundled changes, the absolute value indicates the number of changes
in the same direction, e.g. +3 corresponds to three "volume up" changes. |
