接口 ImageLoader.ImageListener

所有超级接口:
Response.ErrorListener
封闭类:
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.

    • onResponse

      void onResponse(ImageLoader.ImageContainer response, boolean isImmediate)
      Listens for non-error changes to the loading of the image request.
      参数:
      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.
