Icon

Kotlin |Java

class Icon : Parcelable

kotlin.Any
↳	android.graphics.drawable.Icon

An umbrella container for several serializable graphics representations, including Bitmaps, compressed bitmap images (e.g. JPG or PNG), and drawable resources (including vectors). Much ink has been spilled on the best way to load images, and many clients may have different needs when it comes to threading and fetching. This class is therefore focused on encapsulation rather than behavior.

Summary

Nested classes
abstract	OnDrawableLoadedListener Implement this interface to receive a callback when loadDrawableAsync is finished and your Drawable is ready.

Constants
static Int	TYPE_ADAPTIVE_BITMAP An icon that was created using Icon#createWithAdaptiveBitmap.
static Int	TYPE_BITMAP An icon that was created using Icon#createWithBitmap(Bitmap).
static Int	TYPE_DATA An icon that was created using Icon#createWithData(byte[], int, int).
static Int	TYPE_RESOURCE An icon that was created using android.
static Int	TYPE_URI An icon that was created using android.
static Int	TYPE_URI_ADAPTIVE_BITMAP An icon that was created using android.

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.
