AdaptiveIconDrawable

Kotlin |Java

public class AdaptiveIconDrawable
extends Drawable implements Drawable.Callback

java.lang.Object
↳	android.graphics.drawable.Drawable
	↳	android.graphics.drawable.AdaptiveIconDrawable

This class can also be created via XML inflation using <adaptive-icon> tag in addition to dynamic creation.

This drawable supports two drawable layers: foreground and background. The layers are clipped when rendering using the mask defined in the device configuration.

Both foreground and background layers should be sized at 108 x 108 dp.
The inner 72 x 72 dp of the icon appears within the masked viewport.
The outer 18 dp on each of the 4 sides of the layers is reserved for use by the system UI surfaces to create interesting visual effects, such as parallax or pulsing.

Such motion effect is achieved by internally setting the bounds of the foreground and background layer as following:

 Rect(getBounds().left - getBounds().getWidth() * #getExtraInsetFraction(),
      getBounds().top - getBounds().getHeight() * #getExtraInsetFraction(),
      getBounds().right + getBounds().getWidth() * #getExtraInsetFraction(),
      getBounds().bottom + getBounds().getHeight() * #getExtraInsetFraction())

An alternate drawable can be specified using <monochrome> tag which can be drawn in place of the two (background and foreground) layers. This drawable is tinted according to the device or surface theme.

Returns
`Path`	the mask path object used to clip the drawable

getIntrinsicHeight

Added in API level 26

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.

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

getIntrinsicWidth

Added in API level 26

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.

getMonochrome

Added in API level 33

public Drawable getMonochrome ()

Returns the monochrome version of this drawable. Callers can use a tinted version of this drawable instead of the original drawable on surfaces stressing user theming.

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

getOpacity

Added in API level 26

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`

getOutline

Added in API level 26

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`.

getTransparentRegion

Added in API level 26

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`	This value may be `null`.

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 26

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 26

public void invalidateDrawable (Drawable who)

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

invalidateSelf

Added in API level 26

public void invalidateSelf ()

Use the current Callback implementation to have this Drawable redrawn. Does nothing if there is no Callback attached to the Drawable.

isAutoMirrored

Added in API level 26

Added in API level 26

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 26

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 26

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`.

Added in API level 26

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()`

Note: Setting a color filter via setColorFilter(android.graphics.ColorFilter) or setColorFilter(int, android.graphics.PorterDuff.Mode) overrides tint.

Parameters
`tint`	`ColorStateList`: Color state list to use for tinting this drawable, or `null` to clear the tint

setVisible

Added in API level 26

public boolean setVisible (boolean visible, 
                boolean restart)

Set whether this Drawable is visible. This generally does not impact the Drawable's behavior, but is a hint that can be used by some Drawables, for example, to decide whether run animations.

Parameters
`visible`	`boolean`: Set to true if visible, false if not.
`restart`	`boolean`: You can supply true here to force the drawable to behave as if it has just become visible, even if it had last been set visible. Used for example to force animations to restart.

Returns
`boolean`	boolean Returns true if the new visibility is different than its previous state.

unscheduleDrawable

Added in API level 26

public void unscheduleDrawable (Drawable who, 
                Runnable what)

A Drawable can call this to unschedule an action previously scheduled with scheduleDrawable(Drawable, Runnable, long). An implementation can generally simply call Handler.removeCallbacks(Runnable, Object) with the parameters (what, who) to unschedule the drawable.

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

Protected methods

onBoundsChange

Added in API level 26

protected void onBoundsChange (Rect bounds)

Override this in your subclass to change appearance if you vary based on the bounds.

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

onLevelChange

Added in API level 26

protected boolean onLevelChange (int level)

Override this in your subclass to change appearance if you vary based on level.

Parameters
`level`	`int`

Returns
`boolean`	Returns true if the level change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last level.

onStateChange

Added in API level 26

protected boolean onStateChange (int[] state)

Override this in your subclass to change appearance if you recognize the specified state.

Parameters
`state`	`int`: This value cannot be `null`.

Returns
`boolean`	Returns true if the state change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last state.
