NinePatchDrawable

Create drawable from raw nine-patch data, not dealing with density.

Create drawable from raw nine-patch data, setting initial target density based on the display metrics of the resources.

Create drawable from existing nine-patch, not dealing with density.

Create drawable from existing nine-patch, setting initial target density based on the display metrics of the resources.

Applies the specified theme to this Drawable and its children.

Draw in its bounds (set via setBounds) respecting optional effects such as alpha (set via setAlpha) and color filter (set via setColorFilter).

Gets the current alpha value for the drawable. 0 means fully transparent, 255 means fully opaque. This method is implemented by Drawable subclasses and the value returned is specific to how that class treats alpha. The default return value is 255 if the class does not override this method to return a value specific to its use of alpha.

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 setChangingConfigurations(int) or 0 by default. Subclasses may extend this to or in the changing configurations of any other drawables they hold.

Return a Drawable.ConstantState instance that holds the shared state of this Drawable.

Retrieves the height of the source .png file (before resizing).

Retrieves the width of the source .png file (before resizing).

Returns the minimum height suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its height. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.

Returns the minimum width suggested by this Drawable. If a View uses this Drawable as a background, it is suggested that the View use at least this value for its width. (There will be some scenarios where this will not be possible.) This value should INCLUDE any padding.

Returns a graphics.PixelFormat value of OPAQUE or TRANSLUCENT.

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

This method is called by the default ViewOutlineProvider to define the outline of the View.

The default behavior defines the outline to be the bounding rectangle of 0 alpha. Subclasses that wish to convey a different shape or alpha value must override this method.

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 a Region representing the part of the Drawable that is completely transparent. This can be used to perform drawing operations, identifying which parts of the target will not change when rendering the Drawable. The default implementation returns null, indicating no transparent region; subclasses can optionally override this to return an actual Region if they want to supply this optimization information, but it is not required that they do so.

Inflate this Drawable from an XML resource optionally styled by a theme.

Tells if this Drawable will be automatically mirrored when its layout direction is RTL right-to-left. See LayoutDirection.

Indicates whether this drawable will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

Make this drawable mutable. This operation cannot be reversed. A mutable drawable is guaranteed to not share its state with any other drawable. This is especially useful when you need to modify properties of drawables loaded from resources. By default, all drawables instances loaded from the same resource share a common state; if you modify the state of one instance, all the other instances will receive the same modification. Calling this method on a mutable Drawable will have no effect.

Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left). See LayoutDirection.

Specify an optional color filter for the drawable. Pass null to remove any existing color filter.

Set to true to have the drawable dither its colors when drawn to a device with fewer than 8-bits per color component. This can improve the look on those devices, but can also slow down the drawing a little.

Set to true to have the drawable filter its bitmap when scaled or rotated (for drawables that use bitmaps). If the drawable does not use bitmaps, this call is ignored. This can improve the look when scaled or rotated, but also slows down the drawing.

Set the density at which this drawable will be rendered.

Set the density scale at which this drawable will be rendered.

Set the density scale at which this drawable will be rendered. This method assumes the drawable will be rendered at the same density as the specified canvas.

Specifies a tint for this drawable as a color state list.

Setting a color filter via setColorFilter(ColorFilter) overrides tint.

Specifies a tint blending mode for this drawable.

Setting a color filter via setColorFilter(ColorFilter) overrides tint.

Override this in your subclass to change appearance if you recognize the specified state.
