Android set ImageView path dynamically as string

Question

I have 10 images on /resources/drawable folder as following names;
pr1.gif, pr2.gif, ... pr10.gif
And I can easily set an image like this;
imgview1.setImageResource(R.drawable.pr5);

But I can't set it like following;

int pr = getpr(dm);
imgview1.setImageResource(R.drawable.pr + pr);

Is there a way to set it like this or should I use switch case?

I would recommend switch statements.

You can get the id of a drawable by name using getIdentifier():

String prefix = "pr";
int suffix = getpr(dm); // I assume this returns the image number

Resources res = getResources();
int resId = res.getIdentifier(prefix + suffix, "drawable", "my.package.name");
imgview1.setImageResource(resId);

Note you can use this for any type of resource, whether it's drawable, string, array, etc. Just make sure you change the second parameter from "drawable" to the appropriate type.
