Returns the current color filter, or null if none set.

Returns
`ColorFilter`	the current color filter, or `null` if none set

getConstantState

Added in API level 23

public Drawable.ConstantState getConstantState ()

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

Returns
`Drawable.ConstantState`	This value may be `null`.

getDrawable

Added in API level 23

public Drawable getDrawable ()

Returns
`Drawable`	the wrapped drawable This value may be `null`.

getHotspotBounds

Added in API level 23

public void getHotspotBounds (Rect outRect)

Populates outRect with the hotspot bounds.

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

getIntrinsicHeight

Added in API level 23

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 23

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 23

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 23

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 23

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.

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 23

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`: This value cannot be `null`.
`parser`	`XmlPullParser`: This value cannot be `null`.
`attrs`	`AttributeSet`: This value cannot be `null`.
`theme`	`Resources.Theme`: This value may be `null`.

Throws
`IOException`
`XmlPullParserException`

invalidateDrawable

Added in API level 23

public void invalidateDrawable (Drawable who)

Parameters
`who`	`Drawable`: This value cannot be `null`.

isStateful

Added in API level 23

public boolean isStateful ()

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.

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

jumpToCurrentState

Added in API level 23

public void jumpToCurrentState ()

If this Drawable does transition animations between states, ask that it immediately jump to the current state and skip any active animations.

mutate

Added in API level 23

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 value cannot be `null`.

onLayoutDirectionChanged

Added in API level 23

public boolean onLayoutDirectionChanged (int layoutDirection)

Called when the drawable's resolved layout direction changes.

Parameters
`layoutDirection`	`int`: Value is `View.LAYOUT_DIRECTION_LTR`, or `View.LAYOUT_DIRECTION_RTL`

Returns
`boolean`	`true` if the layout direction change has caused the appearance of the drawable to change such that it needs to be re-drawn, `false` otherwise

Added in API level 23

public void scheduleDrawable (Drawable who, 
                Runnable what, 
                long when)

A Drawable can call this to schedule the next frame of its animation. An implementation can generally simply call Handler.postAtTime(Runnable, Object, long) with the parameters (what, who, when) to perform the scheduling.

Parameters
`who`	`Drawable`: This value cannot be `null`.
`what`	`Runnable`: This value cannot be `null`.
`when`	`long`: The time (in milliseconds) to run. The timebase is `SystemClock.uptimeMillis()`

setAlpha

Added in API level 23

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

setColorFilter

Added in API level 23

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`.

Note: Setting a color filter via setColorFilter(android.graphics.ColorFilter)

Parameters
`blendMode`	`BlendMode`: This value cannot be `null`.

setTintList

Added in API level 23

public void setTintList (ColorStateList tint)
