Question

Is there a way to iterate through all the views in your Activity? Something like:

Iterator it = getViewIterator();
...

Does this exi

If you want to avoid the ugly for (int i = 0; ....) you can use a static wrapper

public class Tools
{
    public static Iterable getChildViews(final ViewGroup view)
    {
        return new Iterable()
        {
            int i = -1;

            @NonNull
            @Override
            public Iterator iterator()
            {
                return new Iterator()
                {
                    int i = -1;
                    @Override
                    public boolean hasNext()
                    {
                        return i < view.getChildCount();
                    }

                    @Override
                    public View next()
                    {
                        return view.getChildAt(++i);
                    }
                };
            }

        };
    }
}

and use it like so

for (View view :  Tools.getChildViews(viewGroup))

of course this is slightly less efficient since you are creating a new Iteratable object every time you iterate, but you could build on this a more efficient algo if you want.
