Enclosing class:

Drawable

public static interface Drawable.Callback

• Method Summary

  Methods

  Modifier and Type	Method and Description
  void	invalidateDrawable(Drawable who) Called when the drawable needs to be redrawn.
  void	scheduleDrawable(Drawable who, Runnable what, long when) A Drawable can call this to schedule the next frame of its animation.
  void	unscheduleDrawable(Drawable who, Runnable what) A Drawable can call this to unschedule an action previously scheduled with scheduleDrawable(android.graphics.drawable.Drawable, java.lang.Runnable, long).

• Method Detail

  • invalidateDrawable

    void invalidateDrawable(Drawable who)

    Called when the drawable needs to be redrawn. A view at this point should invalidate itself (or at least the part of itself where the drawable appears).

    Parameters:

    who - The drawable that is requesting the update.

  • scheduleDrawable

    void scheduleDrawable(Drawable who,
                        Runnable what,
                        long when)

    A Drawable can call this to schedule the next frame of its animation. An implementation can generally simply call Handler.postAtTime(Runnable, Object, long) with the parameters (what, who, when) to perform the scheduling.

    Parameters:

    who - The drawable being scheduled.

    what - The action to execute.

    when - The time (in milliseconds) to run. The timebase is SystemClock.uptimeMillis()

  • unscheduleDrawable

    void unscheduleDrawable(Drawable who,
                          Runnable what)

    A Drawable can call this to unschedule an action previously scheduled with scheduleDrawable(android.graphics.drawable.Drawable, java.lang.Runnable, long). An implementation can generally simply call Handler.removeCallbacks(Runnable, Object) with the parameters (what, who) to unschedule the drawable.

    Parameters:

    who - The drawable being unscheduled.

    what - The action being unscheduled.
