  • invalidateDrawable

    public void invalidateDrawable(Drawable who)

    Description copied from interface: Drawable.Callback
    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).

    Specified by:

    invalidateDrawable in interface Drawable.Callback

    Parameters:

    who - The drawable that is requesting the update.

  • scheduleDrawable

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

    Description copied from interface: Drawable.Callback
    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.

    Specified by:

    scheduleDrawable in interface Drawable.Callback

    Parameters:

    who - The drawable being scheduled.

    what - The action to execute.

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

  • unscheduleDrawable

    public void unscheduleDrawable(Drawable who,
                          Runnable what)

    Description copied from interface: Drawable.Callback
    A Drawable can call this to unschedule an action previously scheduled with Drawable.Callback.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.

    Specified by:

    unscheduleDrawable in interface Drawable.Callback

    Parameters:

    who - The drawable being unscheduled.

    what - The action being unscheduled.

  • getChangingConfigurations

    public int getChangingConfigurations()

    Description copied from class: Drawable
    Return a mask of the configuration parameters for which this drawable may change, requiring that it be re-created. The default implementation returns whatever was provided through Drawable.setChangingConfigurations(int) or 0 by default. Subclasses may extend this to or in the changing configurations of any other drawables they hold.

    Overrides:

    getChangingConfigurations in class Drawable

    Returns:

    Returns a mask of the changing configuration parameters, as defined by Configuration.

    See Also:

    Configuration

  • getPadding

    public boolean getPadding(Rect padding)

    Description copied from class: Drawable
    Return in padding the insets suggested by this Drawable for placing content inside the drawable's bounds. Positive values move toward the center of the Drawable (set Rect.inset). Returns true if this drawable actually has a padding, else false. When false is returned, the padding is always set to 0.

    Overrides:

    getPadding in class Drawable

  • setVisible

    public boolean setVisible(boolean visible,
                     boolean restart)

    Description copied from class: Drawable
    Set whether this Drawable is visible. This generally does not impact the Drawable's behavior, but is a hint that can be used by some Drawables, for example, to decide whether run animations.

    Overrides:

    setVisible in class Drawable

    Parameters:

    visible - Set to true if visible, false if not.

    restart - You can supply true here to force the drawable to behave as if it has just become visible, even if it had last been set visible. Used for example to force animations to restart.

    Returns:

    boolean Returns true if the new visibility is different than its previous state.

  • setAlpha

    public void setAlpha(int alpha)

    Description copied from class: Drawable
    Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

    Specified by:

    setAlpha in class Drawable

  • setColorFilter

    public void setColorFilter(ColorFilter cf)

    Description copied from class: Drawable
    Specify an optional colorFilter for the drawable. Pass null to remove any filters.

    Specified by:

    setColorFilter in class Drawable

  • getOpacity

    public int getOpacity()

    Description copied from class: Drawable
    Return the opacity/transparency of this Drawable. The returned value is one of the abstract format constants in PixelFormat: PixelFormat.UNKNOWN, PixelFormat.TRANSLUCENT, PixelFormat.TRANSPARENT, or PixelFormat.OPAQUE.

    Generally a Drawable should be as conservative as possible with the value it returns. For example, if it contains multiple child drawables and only shows one of them at a time, if only one of the children is TRANSLUCENT and the others are OPAQUE then TRANSLUCENT should be returned. You can use the method Drawable.resolveOpacity(int, int) to perform a standard reduction of two opacities to the appropriate single output.

    Note that the returned value does not take into account a custom alpha or color filter that has been applied by the client through the Drawable.setAlpha(int) or Drawable.setColorFilter(android.graphics.ColorFilter) methods.

    Specified by:

    getOpacity in class Drawable

    Returns:

    int The opacity class of the Drawable.

    See Also:

    PixelFormat

  • isStateful

    public boolean isStateful()

    Description copied from class: Drawable
    Indicates whether this view will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

    Overrides:

    isStateful in class Drawable

    Returns:

    True if this view changes its appearance based on state, false otherwise.

    See Also:

    Drawable.setState(int[])

  • onStateChange

    protected boolean onStateChange(int[] state)

    Description copied from class: Drawable
    Override this in your subclass to change appearance if you recognize the specified state.

    Overrides:

    onStateChange in class Drawable

    Returns:

    Returns true if the state change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last state.

  • onLevelChange

    protected boolean onLevelChange(int level)

    Description copied from class: Drawable
    Override this in your subclass to change appearance if you vary based on level.

    Overrides:

    onLevelChange in class Drawable

    Returns:

    Returns true if the level change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last level.

  • onBoundsChange

    protected void onBoundsChange(Rect bounds)

    Description copied from class: Drawable
    Override this in your subclass to change appearance if you recognize the specified state.

    Overrides:

    onBoundsChange in class Drawable

  • draw

    public void draw(Canvas canvas)

    Description copied from class: Drawable
    Draw in its bounds (set via setBounds) respecting optional effects such as alpha (set via setAlpha) and color filter (set via setColorFilter).

    Specified by:

    draw in class Drawable

    Parameters:

    canvas - The canvas to draw into

  • getIntrinsicWidth

    public int getIntrinsicWidth()

    Description copied from class: Drawable

    Overrides:

    getIntrinsicWidth in class Drawable

  • getIntrinsicHeight

    public int getIntrinsicHeight()

    Description copied from class: Drawable
    Return the intrinsic height of the underlying drawable object. Returns -1 if it has no intrinsic height, such as with a solid color.

    Overrides:

    getIntrinsicHeight in class Drawable

  • getConstantState

    public Drawable.ConstantState getConstantState()

    Description copied from class: Drawable

    Drawable.ConstantState, Drawable.mutate()

  • setLayoutDirection

    public void setLayoutDirection(int layoutDirection)

    Description copied from class: Drawable
