ShadowChoreographer

public ShadowChoreographer()

Method Detail

setPostCallbackDelay

public static void setPostCallbackDelay(int delayMillis)

Allows application to specify a fixed amount of delay when #postCallback(int, Runnable, Object) is invoked. The default delay value is 0. This can be used to avoid infinite animation tasks to be spawned when the Robolectric Scheduler is in Scheduler.IdleState.PAUSED mode.

Only supported in LooperMode.Mode.LEGACY

setPostFrameCallbackDelay

public static void setPostFrameCallbackDelay(int delayMillis)

Allows application to specify a fixed amount of delay when #postFrameCallback(FrameCallback) is invoked. The default delay value is 0. This can be used to avoid infinite animation tasks to be spawned when in LooperMode PAUSED or Scheduler.IdleState.PAUSED and displaying an animation.

getFrameInterval

public static long getFrameInterval()

Return the current inter-frame interval.

Can only be used in LooperMode.Mode.LEGACY

Returns:

Inter-frame interval.

setFrameInterval

public static void setFrameInterval(long frameInterval)

Set the inter-frame interval used to advance the clock. By default, this is set to 1ms.

Only supported in LooperMode.Mode.LEGACY

Parameters:

frameInterval - Inter-frame interval.

doFrame

@Implementation(maxSdk=30)
protected void doFrame(long frameTimeNanos,
                       int frame)
