Just a slight modification to the existing Generalized File Manager. This one is with a better UI (hopefully
) which makes use of the existing Toolbar functionality.
The snaps should hopefully explain the functionality, if not please let me know.
The IconifiedText.java , IconifiedTextListAdapter.java and IconifiedTextView.java remains the same from the initial version of Generalized File Manager.

All the other xml files remain the same.
The GFM2.0 makes use of the LEFT and RIGHT KEYPAD buttons to navigate to the icons.
As usual i have an issue
However on click of the Left or Right Keypad button, there is a considerable amount of delay. what i mean is that the focus first goes to the icon and after about a second only the file types are listed. Not sure if this is bcoz of the slowness of my PC(700MHZ)..
Please let me know of any improvements.
And now to the snaps!!
Thanx,
Nitin
