getConstantState

Added in API level 1

public Drawable.ConstantState getConstantState ()

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

Returns
`Drawable.ConstantState`	The ConstantState associated to that Drawable. This value may be `null`.

getIntrinsicHeight

Added in API level 1

public int getIntrinsicHeight ()

Returns the drawable's intrinsic height.

Intrinsic height is the height at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic height, such as a solid color, this method returns -1.

Returns
`int`	the intrinsic height, or -1 if no intrinsic height

getIntrinsicWidth

Added in API level 1

public int getIntrinsicWidth ()

Returns the drawable's intrinsic width.

Intrinsic width is the width at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic width, such as a solid color, this method returns -1.

Returns
`int`	the intrinsic width, or -1 if no intrinsic width

getOpacity

Added in API level 1

public int getOpacity ()

This method is deprecated.
This method is no longer used in graphics optimizations

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.

An OPAQUE drawable is one that draws all all content within its bounds, completely covering anything behind the drawable. A TRANSPARENT drawable is one that draws nothing within its bounds, allowing everything behind it to show through. A TRANSLUCENT drawable is a drawable in any other state, where the drawable will draw some, but not all, of the content within its bounds and at least some content behind the drawable will be visible. If the visibility of the drawable's contents cannot be determined, the safest/best return value is TRANSLUCENT.

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 resolveOpacity(int, int) to perform a standard reduction of two opacities to the appropriate single output.

Note that the returned value does not necessarily take into account a custom alpha or color filter that has been applied by the client through the setAlpha(int) or setColorFilter(ColorFilter) methods. Some subclasses, such as BitmapDrawable, ColorDrawable, and GradientDrawable, do account for the value of setAlpha(int), but the general behavior is dependent upon the implementation of the subclass.

Returns
`int`	int The opacity class of the Drawable. Value is `PixelFormat.UNKNOWN`, `PixelFormat.TRANSLUCENT`, `PixelFormat.TRANSPARENT`, or `PixelFormat.OPAQUE`

getOpticalInsets

Added in API level 29

public Insets getOpticalInsets ()

Return in insets the layout insets suggested by this Drawable for use with alignment operations during layout.

Returns
`Insets`	This value cannot be `null`.

getOutline

Added in API level 21

public void getOutline (Outline outline)

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.

Parameters
`outline`	`Outline`: This value cannot be `null`.

getPadding

Added in API level 1

public boolean getPadding (Rect padding)

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).

Parameters
`padding`	`Rect`: This value cannot be `null`.

Returns
`boolean`	true if this drawable actually has a padding, else false. When false is returned, the padding is always set to 0.

getPaint

Added in API level 1

public Paint getPaint ()

Returns
`Paint`	This value cannot be `null`.

getTransparentRegion

Added in API level 1

public Region getTransparentRegion ()

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.

Returns
`Region`	Returns null if the Drawables has no transparent region to report, else a Region holding the parts of the Drawable's bounds that are transparent.

hasFocusStateSpecified

Added in API level 31

public boolean hasFocusStateSpecified ()

Indicates whether this drawable has at least one state spec explicitly specifying R.attr.state_focused.

Note: A View uses a Drawable instance as its background and it changes its appearance based on a state. On keyboard devices, it should specify its R.attr.state_focused to make sure the user knows which view is holding the focus.

Returns
`boolean`	`true` if `R.attr.state_focused` is specified for this drawable.

inflate

Added in API level 21

public void inflate (Resources r, 
                XmlPullParser parser, 
                AttributeSet attrs, 
                Resources.Theme theme)

Inflate this Drawable from an XML resource optionally styled by a theme. This can't be called more than once for each Drawable. Note that framework may have called this once to create the Drawable instance from XML resource.

Parameters
`r`	`Resources`: Resources used to resolve attribute values This value cannot be `null`.
`parser`	`XmlPullParser`: XML parser from which to inflate this Drawable This value cannot be `null`.
`attrs`	`AttributeSet`: Base set of attribute values This value cannot be `null`.

Added in API level 23

public boolean isFilterBitmap ()

Returns
`boolean`	whether this drawable filters its bitmaps

Returns
`boolean`	True if this drawable changes its appearance based on state, false otherwise.

mutate

Added in API level 3

public Drawable mutate ()

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.

Returns
`Drawable`	This drawable. This value cannot be `null`.

setAlpha

Added in API level 1

public void setAlpha (int alpha)

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

Parameters
`alpha`	`int`: Value is between 0 and 255 inclusive

setAutoMirrored

Added in API level 19

public void setAutoMirrored (boolean mirrored)

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

Parameters
`mirrored`	`boolean`: Set to true if the Drawable should be mirrored, false if not.

setColorFilter

Added in API level 1

public void setColorFilter (ColorFilter colorFilter)

Specify an optional color filter for the drawable.

If a Drawable has a ColorFilter, each output pixel of the Drawable's drawing contents will be modified by the color filter before it is blended onto the render target of a Canvas.

Pass null to remove any existing color filter.

Note: Setting a non-null color filter disables tint.

Parameters
`colorFilter`	`ColorFilter`: This value may be `null`.

setDither

Added in API level 1
