• Constructor Detail

  • ColorDrawable

    public ColorDrawable()

    Creates a new black ColorDrawable.

  • ColorDrawable

    public ColorDrawable(int color)

    Creates a new ColorDrawable with the specified color.

    Parameters:

    color - The color to draw.

• Method Detail

  • 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.

  • mutate

    public Drawable mutate()

    A mutable BitmapDrawable still shares its Bitmap with any other Drawable that comes from the same resource.

    Overrides:

    mutate in class Drawable

    Returns:

    This drawable.

    See Also:

    Drawable.ConstantState, Drawable.getConstantState()

  • 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

  • getColor

    public int getColor()

    Gets the drawable's color value.

    Returns:

    int The color to draw.

  • setColor

    public void setColor(int color)

    Sets the drawable's color value. This action will clobber the results of prior calls to setAlpha(int) on this object, which side-affected the underlying color.

    Parameters:

    color - The color to draw.

  • getAlpha

    public int getAlpha()

    Returns the alpha value of this drawable's color.

    Returns:

    A value between 0 and 255.

  • setAlpha

    public void setAlpha(int alpha)

    Sets the color's alpha value.

    Specified by:

    setAlpha in class Drawable

    Parameters:

    alpha - The alpha value to set, between 0 and 255.

  • setColorFilter

    public void setColorFilter(ColorFilter colorFilter)

    Setting a color filter on a ColorDrawable has no effect.

    Specified by:

    setColorFilter in class Drawable

    Parameters:

    colorFilter - Ignore.

  • 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.

    PixelFormat

  • inflate

    public void inflate(Resources r,
               XmlPullParser parser,
               AttributeSet attrs)
                 throws XmlPullParserException,
                        IOException

    Description copied from class: Drawable
    Inflate this Drawable from an XML resource.

    Overrides:

    inflate in class Drawable

    Throws:

    XmlPullParserException

    IOException

  • getConstantState

    public Drawable.ConstantState getConstantState()

    Description copied from class: Drawable
    Return a Drawable.ConstantState instance that holds the shared state of this Drawable. q

    Overrides:

    getConstantState in class Drawable

    Returns:

    The ConstantState associated to that Drawable.

    Drawable.ConstantState, Drawable.mutate()
