Facebook – OpenID Connect Configuration for Facebook

OpenID is about authentication (ie. proving who you are), OAuth is about authorisation (ie. to grant access to functionality/data/etc.. without having to deal with the original authentication).

OAuth could be used in external partner sites to allow access to protected data without them having to re-authenticate a user.

The blog post "OpenID versus OAuth from the user’s perspective" has a simple comparison of the two from the user's perspective and "OAuth-OpenID: You’re Barking Up the Wrong Tree if you Think They’re the Same Thing" has more information about it.

One way to do it is by modifying your getView() method of your adapter, so that it uses the ViewHolder pattern (Romain Guy's Google I/O 2009 presentation, look at 0:09:05).

In your view holder that you tag to the view, you can add field for the resource ID. When you get your selected view, find the view holder (view.getTag()) and get its ID field.

You can pass it to another Activity by using Intents.

You may have to use ContentProvider so that the second Activity has access to your chosen image. Keep in mind that, more often than not, the resources that are compiled in your .apk and have an ID are small, utility ones, because otherwise they bulk up your application, and most of the time, you can count on using the Internet to download images.

Of course, that's not always the case, but if you are simulating Internet resources with res/drawable resources, chances are, you'll face different problems.

Good luck.
