Assume you have several drawables in your Android resource folder and what to iterate over them. You use a certain naming schema and would like to use this to determine the resources ID’s.
The following snippets shows how to get a resource ID based on the resource name:
// Name of resource
// Package of the app
int identifier = getResources().getIdentifier("pic1", "drawable","android.demo");
ImageView image = (ImageView) findViewById(R.id.imageView1);
I hope this helps.
