Interface ImageLoader.ImageListener

All Superinterfaces:

Response.ErrorListener

Enclosing class:

ImageLoader

public static interface ImageLoader.ImageListener
extends Response.ErrorListener

Interface for the response handlers on image requests.

The call flow is this: 1. Upon being attached to a request, onResponse(response, true) will be invoked to reflect any cached data that was already available. If the data was available, response.getBitmap() will be non-null.

2. After a network response returns, only one of the following cases will happen: - onResponse(response, false) will be called if the image was loaded. or - onErrorResponse will be called if there was an error loading the image.

Method Summary

Method Detail

onResponse

void onResponse(ImageLoader.ImageContainer response,
                boolean isImmediate)

Listens for non-error changes to the loading of the image request.

Parameters:

response - Holds all information pertaining to the request, as well as the bitmap (if it is loaded).

isImmediate - True if this was called during ImageLoader.get() variants. This can be used to differentiate between a cached image loading and a network image loading in order to, for example, run an animation to fade in network loaded images.
