Hello - I'm trying to figure out the best design pattern to use here.
I have a list view, for which each row consists of some text and an image. This content must be downloaded from the web. Currently, the list view is using a custom adapter, and I implemented the getView() method to dynamically download the image as it is needed (i.e. as the row on which it should be displayed becomes visible). This is all happening in the main thread, and it's having an impact on the user experience. So I'd like to move the downloading of the image to the background thread. I know how to do this ... but my quandary is then, how do I pass the image information back to the main UI thread. AFAIK, the most convenient way to pass information between threads is using Handler.sendMessage() and including a bundle with the message containing any information. But I don't think it's possible to include an Image as part of a bundle, because it's not serializable. Do I need to write the image to disk and pass a string containing the file path? what are some other ways I could go about passing information about a downloaded image from the non-UI background thread to the ui thread?
