AutoCompleteTextView - Example

An editable text view that shows completion suggestions automatically while the user is typing. The list of suggestions is displayed in a drop down menu from which the user can choose an item to replace the content of the edit box with.

> The drop down can be dismissed at any time by pressing the back key or, if no item is selected in the drop down, by pressing the enter/dpad center key.

> The list of suggestions is obtained from a data adapter and appears only after a given number of characters defined by the ThresHold.
