| ↳ | 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.

Parcelable interface
Returns a Drawable that can be used to draw the image inside this Icon, constructing it
if necessary. Depending on the type of image, this may not be something you want to do on
the UI thread, so consider using
loadDrawableAsync instead.
Invokes loadDrawable(Context) on a background thread
and then runs andThen on the UI thread when finished.
| context | Context in which to load the drawable; see
loadDrawable(Context) |
|---|---|
| listener | a callback to run on the provided |
| handler | Handler on which to run andThen.
|
Invokes loadDrawable(Context) on the given Handler
and then sends andThen to the same Handler when finished.
| context | Context in which to load the drawable; see
loadDrawable(Context) |
|---|---|
| andThen | Message to send to its target once the drawable
is available. The obj
property is populated with the Drawable.
|
Store a color to use whenever this Icon is drawn.
| tint | a color, as in setTint(int) |
|---|
Store a color to use whenever this Icon is drawn.
| tintList | as in setTintList(ColorStateList), null to remove tint |
|---|
Store a blending mode to use whenever this Icon is drawn.
| mode | a blending mode, as in setTintMode(PorterDuff.Mode), may be null |
|---|
Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
getClass().getName() + '@' + Integer.toHexString(hashCode())
See Writing a useful
toString method
if you intend implementing your own toString method.
Flatten this object in to a Parcel.
| dest | The Parcel in which the object should be written. |
|---|---|
| flags | Additional flags about how the object should be written.
May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
