    setAlpha(alpha: number): void
}

  • Description​

    Specify an alpha value for the drawable.

onBoundsChange​

declare class Drawable {
    onBoundsChange(bounds: Rect): void
}

  • Description​

    Override this in your subclass to change appearance if you vary based on the bounds.

copyBounds​

declare class Drawable {
    copyBounds() : Rect

}

  • Description​

    Return a copy of the drawable's bounds in the specified Rect (allocated by the caller).

getMinimumWidth​

declare class Drawable {
    getMinimumWidth(): number
}

  • Description​

getMinimumHeight​

declare class Drawable {
    getMinimumHeight(): number
}

  • Description​

    Returns the minimum height suggested by this Drawable.

getBounds​

declare class Drawable {
    getBounds(): Rect
}

  • Description​

    Return the drawable's bounds Rect.

getOutline​

declare class Drawable {
    getOutline(outline:Outline):void

  • Description​

    Called to get the drawable to populate the Outline that defines its drawing area.

getCallback​

declare class Drawable {
    getCallback() :Drawable.Callback
}

  • Description​

    Return the current Callback implementation attached to this Drawable.

getIntrinsicWidth​

declare class Drawable {
    getIntrinsicWidth(): number
}

  • Description​

    Returns the drawable's intrinsic width.

getIntrinsicHeight​

declare class Drawable {
    getIntrinsicHeight():number
}

  • Description​

    Returns the drawable's intrinsic height.

getIntrinsicHeight​

declare class Drawable {
    setBounds(bounds: Rect): void;
    setBounds(left: number, top: number, right: number, bottom: number): void;
}

  • Description​

    Specify a bounding rectangle for the Drawable.

setCallback​

declare class Drawable {
    setCallback(callback: Drawable.Callback): void
}

  • Description​

    Bind a Callback object to this Drawable.

Drawable.ConstantState​

ConstantState

declare abstract class ConstantState {
    public abstract newDrawable(): Drawable;
    
    public newResourcesDrawable(res: Resources): Drawable;
    
    public abstract getChangingConfigurations(): number;
}

Instance Method​

newDrawable​

declare class ConstantState {
    newDrawable(): Drawable
}

  • Description​

    Creates a new Drawable instance from its constant state.

newResourcesDrawable​

declare class ConstantState {
    newResourcesDrawable(res: Resources): Drawable
}

  • Description​

    Creates a new Drawable instance from its constant state using the specified resources.

getChangingConfigurations​

declare class ConstantState {
    getChangingConfigurations(): number
}

  • Description​

    Return a bit mask of configuration changes that will impact this drawable (and thus require completely reloading it).

Drawable.Callback​

Callback

declare interface Callback {
    invalidateDrawable(who:Drawable): void

    scheduleDrawable(who: Drawable, what: Runnable, when: number): void

    unScheduleDrawable(who: Drawable, what: Runnable): void
}

Instance Method​

invalidateDrawable​

declare class ConstantState {
    invalidateDrawable(who:Drawable): void
}

  • Description​

    Called when the drawable needs to be redrawn.

scheduleDrawable​

declare class ConstantState {
    scheduleDrawable(who: Drawable, what: Runnable, when: number): void
}

  • Description​

    A Drawable can call this to schedule the next frame of its animation.

unScheduleDrawable​

declare class ConstantState {
    unScheduleDrawable(who: Drawable, what: Runnable): void
}

  • Description​

    A Drawable can call this to unschedule an action previously scheduled with scheduleDrawable(Drawable, Runnable, long).
