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.

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

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. q

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.

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.

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.

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.

Specify an optional colorFilter for the drawable. Pass null to remove any filters.

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 scale at which this drawable will be rendered.

Set the density 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.
