示例1: UnbindView

        public void UnbindView (View view)
        {
            if (view == null)
                return;

                if (tag.Bindings != null) {
                    foreach (var binding in tag.Bindings) {
                        binding.Dispose();

                    tag.Bindings.Clear();
                }

                _viewTags.RemoveAll(weak => weak.Target == tag || weak.Target == null);
            }

            var viewGroup = view as ViewGroup;

                var count = viewGroup.ChildCount;
                for (var i = 0; i < count; i++) {
                    UnbindView(viewGroup.GetChildAt(i));
                }
