You want to count particular pictures with starting some name.. Then use `Asset` instead of Drawables. — user370305, Apr 01 '14 at 08:24

You can use reflection for that. Simply use getDeclaredFields() to get all fields of R.drawable.class. Then, just loop through them, look for the search term in the field names and get the drawable using Resources.getDrawable(Field.getInt());.

Well,

I haven't tried it but you can use getFields() to get all the variables

R.drawable.class.getFields()

Then you can perform your search for specific file name accordingly.
