↳	android.graphics.drawable.Drawable
	↳	android.graphics.drawable.DrawableWrapper

It can be defined in an XML file with the <inset> element. For more information, see the guide to Drawable Resources.

Public methods

applyTheme

Added in API level 21

public void applyTheme (Resources.Theme t)

Applies the specified theme to this Drawable and its children.

Parameters
`t`	`Resources.Theme`: This value cannot 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.

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`: 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

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