NinePatchDrawable

Kotlin |Java

open class NinePatchDrawable : Drawable

kotlin.Any
↳	android.graphics.drawable.Drawable
	↳	android.graphics.drawable.NinePatchDrawable

A resizeable bitmap, with stretchable areas that you define. This type of image is defined in a .png file with a special format.

Summary

Public constructors
`NinePatchDrawable(res: Resources!, bitmap: Bitmap!, chunk: ByteArray!, padding: Rect!, srcName: String!)` Create drawable from raw nine-patch data, setting initial target density based on the display metrics of the resources.
`NinePatchDrawable(res: Resources?, patch: NinePatch)` Create drawable from existing nine-patch, setting initial target density based on the display metrics of the resources.
`NinePatchDrawable(bitmap: Bitmap!, chunk: ByteArray!, padding: Rect!, srcName: String!)` Create drawable from raw nine-patch data, not dealing with density.
`NinePatchDrawable(patch: NinePatch)` Create drawable from existing nine-patch, not dealing with density.

Public methods
open Unit	`applyTheme(t: Resources.Theme)` Applies the specified theme to this Drawable and its children.

open Int	`getOpacity()` Return the opacity/transparency of this Drawable.
open Insets	`getOpticalInsets()` Return in insets the layout insets suggested by this Drawable for use with alignment operations during layout.
open Unit	`getOutline(outline: Outline)` Called to get the drawable to populate the Outline that defines its drawing area.
open Boolean	`getPadding(padding: Rect)` Return in padding the insets suggested by this Drawable for placing content inside the drawable's bounds.
open Paint	`getPaint()`
open Region?	`getTransparentRegion()` Returns a Region representing the part of the Drawable that is completely transparent.
open Boolean	`hasFocusStateSpecified()` Indicates whether this drawable has at least one state spec explicitly specifying `android.R.attr#state_focused`.
open Unit	`inflate(r: Resources, parser: XmlPullParser, attrs: AttributeSet, theme: Resources.Theme?)` Inflate this Drawable from an XML resource optionally styled by a theme.
open Boolean	`isAutoMirrored()` Tells if this Drawable will be automatically mirrored when its layout direction is RTL right-to-left.
open Boolean	`isFilterBitmap()`
open Boolean	`isStateful()` Indicates whether this drawable will change its appearance based on state.
open Drawable	`mutate()` Make this drawable mutable.
open Unit	`setAlpha(alpha: Int)` Specify an alpha value for the drawable.
open Unit	`setAutoMirrored(mirrored: Boolean)` Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left).
open Unit	`setColorFilter(colorFilter: ColorFilter?)` Specify an optional color filter for the drawable.
open Unit	`setDither(dither: Boolean)` Set to true to have the drawable dither its colors when drawn to a device with fewer than 8-bits per color component.
open Unit	`setFilterBitmap(filter: Boolean)` Set to true to have the drawable filter its bitmaps with bilinear sampling when they are scaled or rotated.
open Unit	`setTargetDensity(canvas: Canvas)` Set the density scale at which this drawable will be rendered.
open Unit	`setTargetDensity(metrics: DisplayMetrics)` Set the density scale at which this drawable will be rendered.
open Unit	`setTargetDensity(density: Int)` Set the density at which this drawable will be rendered.
open Unit	`setTintBlendMode(blendMode: BlendMode?)` Specifies a tint blending mode for this drawable.
open Unit	`setTintList(tint: ColorStateList?)` Specifies tint color for this drawable as a color state list.

Protected methods
open Boolean	`onStateChange(stateSet: IntArray)` Override this in your subclass to change appearance if you recognize the specified state.

Inherited functions

From class Drawable

`Unit`	`clearColorFilter()` Removes the color filter for this drawable.
`Rect`	`copyBounds()` Return a copy of the drawable's bounds in a new Rect. This returns the same values as getBounds(), but the returned object is guaranteed to not be changed later by the drawable (i.e. it retains no reference to this rect). If the caller already has a Rect allocated, call copyBounds(rect).
`Unit`	`copyBounds(bounds: Rect)` Return a copy of the drawable's bounds in the specified Rect (allocated by the caller). The bounds specify where this will draw when its draw() method is called.
`Drawable?`	`createFromPath(pathName: String!)` Create a drawable from file path name.
`Drawable?`	`createFromResourceStream(res: Resources?, value: TypedValue?, is: InputStream?, srcName: String?)` Create a drawable from an inputstream, using the given resources and value to determine density information.
`Drawable?`	`createFromResourceStream(res: Resources?, value: TypedValue?, is: InputStream?, srcName: String?, opts: BitmapFactory.Options?)` Create a drawable from an inputstream, using the given resources and value to determine density information.
`Drawable?`	`createFromStream(is: InputStream?, srcName: String?)` Create a drawable from an inputstream
`Drawable`	`createFromXml(r: Resources, parser: XmlPullParser)` Create a drawable from an XML document. For more information on how to create resources in XML, see Drawable Resources.
`Drawable`	`createFromXml(r: Resources, parser: XmlPullParser, theme: Resources.Theme?)` Create a drawable from an XML document using an optional `Theme`. For more information on how to create resources in XML, see Drawable Resources.
`Drawable`	`createFromXmlInner(r: Resources, parser: XmlPullParser, attrs: AttributeSet)` Create from inside an XML document. Called on a parser positioned at a tag in an XML document, tries to create a Drawable from that tag. Returns null if the tag is not a valid drawable.
`Drawable`	`createFromXmlInner(r: Resources, parser: XmlPullParser, attrs: AttributeSet, theme: Resources.Theme?)` Create a drawable from inside an XML document using an optional `Theme`. Called on a parser positioned at a tag in an XML document, tries to create a Drawable from that tag. Returns `null` if the tag is not a valid drawable.
`Rect`	`getBounds()` Return the drawable's bounds Rect. Note: for efficiency, the returned object may be the same object stored in the drawable (though this is not guaranteed), so if a persistent copy of the bounds is needed, call copyBounds(rect) instead. You should also not change the object returned by this method as it may be the same object stored in the drawable.
`Drawable.Callback?`	`getCallback()` Return the current `Callback` implementation attached to this Drawable.
`ColorFilter?`	`getColorFilter()` Returns the current color filter, or `null` if none set.
`Drawable`	`getCurrent()`
`Rect`	`getDirtyBounds()` Return the drawable's dirty bounds Rect. Note: for efficiency, the returned object may be the same object stored in the drawable (though this is not guaranteed). By default, this returns the full drawable bounds. Custom drawables may override this method to perform more precise invalidation.
`Unit`	`getHotspotBounds(`
