How to display list of resource drawables [duplicate]

Question

I would like to display all resource drawables in a list so that the user can select one. Is there any way to loop through all R.drawable items so I don't have to hard code them into my program?

Answer 1

Using the getFields method on the drawable class, you are able to iterate through the entire list of drawables.

Field[] drawables = android.R.drawable.class.getFields();
for (Field f : drawables) {
    try {
        System.out.println("R.drawable." + f.getName());
    } catch (Exception e) {
        e.printStackTrace();
    }
}
