"once i enter i want it to view something on a text view automatically" means? — Naresh, Jul 21 '13 at 11:13
Use debugger or logging to check if `onKeyUp()` is called and with which parameters (especially which `i`) — Michael Butscher, Jul 21 '13 at 11:40

Take your input value in an EditText. Compare your EditText's value and accordingly change your TextView. I don't see any use of onKeyUp method.

Or if you really want to use onKeyUp method, I guess this link might help you!
