Protected methods

down

added in API level 1
protected boolean down (TextView widget, 
                Spannable buffer)

Performs a down movement action. Moves the cursor or scrolls down by one line.

Parameters
widget TextView: The text view.

buffer Spannable: The text buffer.

Returns
boolean True if the event was handled.

handleMovementKey

added in API level 11
protected boolean handleMovementKey (TextView widget, 
                Spannable buffer, 
                int keyCode, 
                int movementMetaState, 
                KeyEvent event)

Performs a movement key action. The default implementation decodes the key down and invokes movement actions such as down(TextView, Spannable) and up(TextView, Spannable). onKeyDown(TextView, Spannable, int, KeyEvent) calls this method once to handle an KeyEvent.ACTION_DOWN. onKeyOther(TextView, Spannable, KeyEvent) calls this method repeatedly to handle each repetition of an KeyEvent.ACTION_MULTIPLE.

Parameters
widget TextView: The text view.

buffer Spannable: The text buffer.

keyCode int: The key code.

movementMetaState int: The keyboard meta states used for movement.

event KeyEvent: The key event.

Returns
boolean True if the event was handled.
