set source of ImageView dynamically android

Question

I have an ImageView on my scene that I would like to set the source of dynamically based on user input.

Let\'s say I have 4 images in my drawable folder: aaa.png, bbb.pn

If you want to allow open text input, you'll either have to use raw assets to fetch them by string name (see the sidenote on that page), or else use magical Java reflection to retrieve a field of the R class by name. Alternatively, you could keep a HashMap of strings to R.drawable integer values and look it up, but then you'd have to maintain that hashmap.
