Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

`WallpaperColors(primaryColor: Color, secondaryColor: Color?, tertiaryColor: Color?, colorHints: Int)` Constructs a new object from three colors, where hints can be specified.
`WallpaperColors(parcel: Parcel!)`

Public methods
Int	`describeContents()`
Boolean	`equals(other: Any?)` Indicates whether some other object is "equal to" this one.
static WallpaperColors!	`fromBitmap(bitmap: Bitmap)` Constructs `WallpaperColors` from a bitmap.

Int	`getColorHints()` Returns the color hints for this instance.
Color	`getPrimaryColor()` Gets the most visually representative color of the wallpaper.
Color?	`getSecondaryColor()` Gets the second most preeminent color of the wallpaper.
Color?	`getTertiaryColor()` Gets the third most preeminent color of the wallpaper.

WallpaperColors

Added in API level 27

WallpaperColors(parcel: Parcel!)

Public methods

describeContents

Added in API level 27

fun describeContents(): Int

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

equals

Added in API level 27

fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
`obj`	the reference object with which to compare.
`o`	This value may be `null`.

Return
`Boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

fromBitmap

Added in API level 27

static fun fromBitmap(bitmap: Bitmap): WallpaperColors!

Constructs WallpaperColors from a bitmap.

Main colors will be extracted from the bitmap.

Parameters
`bitmap`	Bitmap: Source where to extract from. This value cannot be `null`.

fromDrawable

Added in API level 27

static fun fromDrawable(drawable: Drawable!): WallpaperColors!
