Is there a way to do this...R.Id."string"?

I have a folder called "raw" in my Res folder with a selection of short audio tracks and the screen displays several buttons.

I would like to be able to start the MediaPlayer like this...

String[] track = {"track1", "track2", "track3", etc...}

mPlayer = MediaPlayer.create(this, R.raw.track[x]);

The issue is with the R.raw.track[x].

Is there a way to do this in the way I'm attempting or do I need a whole new approach?

Thanks in advance for any advice you can offer.

I am going to assume here that your x is an index, perhaps pulled from a user selection from track.

You have two main options:

  1. Have a corresponding int[] {R.raw.track1, R.raw.track2, ...} and look up the R.raw value that way

  2. Use getResources().getIdentifier() to look up an identifier at runtime

The second option is easier but uses reflection and so is not super-quick. In your case, that should not matter, as I doubt that you are looking up these IDs in a tight loop.
