agregando una interfaz textView to Drag and Drop-Android/Java

gridview drag-and-drop

Question

Tengo un gridView I''ve build del siguiente tutorial / ejemplo:

http://blahti.wordpress.com/2012/03/03/improved-drag-drop-for-gridview/

Tal como está: la fuente del ejemplo (disponible para descargar en el siguiente enlace) permite arrastrar y soltar un nuevo imageView cuadrado y colocarlo dentro de la vista grid.

Lo que estoy intentando lograr ahora es poder crear un textView que se pueda arrastrar y soltar (junto con el imageView) para crear una carpeta con un título que se pueda arrastrar y soltar.

Hasta ahora, he logrado crear mi propia versión personalizada (nuevos mosaicos, etc., así como un editText que al hacer clic se convierte en una versión de TextView) de gridView, así como también una vista de texto, simplemente no puedo conseguir que avance. con imageView cuando se arrastra.
