handleMovementKey
boolean handleMovementKey (TextView widget,

such as down(TextView, Spannable) and up(TextView, Spannable).
onKeyDown(TextView, Spannable, int, KeyEvent) calls this method once
to handle an ACTION_DOWN.
onKeyOther(TextView, Spannable, KeyEvent) calls this method repeatedly
to handle each repetition of an ACTION_MULTIPLE.

TextView:
The text view. |
buffer |
Spannable:
The text buffer. |
keyCode |
int:
