Can I store the int IDs of drawable in an XML?

Question

So I'm trying to organize my data into an XML as such:

<hands>
    <punch>
        <id>1</id>
        <move>Reverse Punch</move>
        <jap>Gyaku Zuki</jap>
        <thumb>2130837505</thumb>
    </punch>
</hands>

The data from the XML gets parsed and ends up in a hashmap. I'd like to draw them like so:

thumb.setImageURI(Uri.parse(Main.ROOT + Integer.parseInt(moveList.get(MoveView.KEY_THUMB))));

Is using the ID instead of referencing them via R.drawable.img alright?

Thank you!

You should not store the constants from R class and you should always refer to them by R.drawable.img. The reason for it is that the integer values may change at any time and are not guaranteed to be the same every time you build your app.

That's what I was afraid of. Is there any way to draw them from a string? – Amorphous Dec 22 '13 at 09:56

You should store the name of image in drawable. In your case you should store "img" and use this code to get android Id in your app:

int id = getResources().getIdentifier(elementName,"drawable", getPackageName());
