Accessing Android Resources By Name at Runtime
Use the getIdentifier method passing it the name of your resource, the resource type (id, raw) and your package name ( just use getPackageName())
int id = getResources().getIdentifier("name_of_resource", "id", getPackageName());
After that you can use the id just like you would at compile time using the R class.
Updated: May 21, 2010 – The code that was here for a long time was awful and dated, so I’ve updated this post.

See Resources.getIdentifier. For example: http://www.anddev.org/viewtopic.php?p=17846

Ah, absolutely. This post is _very_ dated and I not recommend using my code example to anyone.

but with the example http://www.anddev.org/viewtopic.php?p=17846, we can’t get a button id for example. Steven, it could be possible with your code example, but is it recommendable? please, help me with this little trouble. (you can send me a mail)

This code is really dated, I know there is a much cleaner way to do this now, but unfortunately I haven’t kept up with my Android development and can’t be to much help.

Carlos,
You want this:
Log.i(TAG, “Found Button ID: ” + getResources().getIdentifier(“Button01″, “id”, “com.android.test”));
or
Log.i(TAG, “Found Button ID: ” + getResources().getIdentifier(“com.android.test:id/Button01″));
The code mentioned shows how to get a drawable, just replace drawable for another type in the resource file (id, drawable, layout, string, etc)
