public void initialize (TextView widget, 
                Spannable text)

onKeyUp

public boolean onKeyUp (TextView widget, 
                Spannable text, 
                int keyCode, 
                KeyEvent event)

onTakeFocus

public void onTakeFocus (TextView widget, 
                Spannable text, 
                int direction)

onTouchEvent

public boolean onTouchEvent (TextView widget, 
                Spannable text, 
                MotionEvent event)

onTrackballEvent

public boolean onTrackballEvent (TextView widget, 
                Spannable text, 
                MotionEvent event)

previousParagraph

public boolean previousParagraph (TextView widget, 
                Spannable buffer)

Performs a previous paragraph movement action.

bottom

protected boolean bottom (TextView widget, 
                Spannable buffer)

Performs a bottom movement action. Moves the cursor or scrolls to the bottom of the buffer.

down

protected boolean down (TextView widget, 
                Spannable buffer)

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

end

protected boolean end (TextView widget, 
                Spannable buffer)

Performs an end movement action. Moves the cursor or scrolls to the start of the line or to the top of the document depending on whether the insertion point is being moved or the document is being scrolled.

getMovementMetaState

protected int getMovementMetaState (Spannable buffer, 
                KeyEvent event)

Gets the meta state used for movement using the modifiers tracked by the text buffer as well as those present in the key event. The movement meta state excludes the state of locked modifiers or the SHIFT key since they are not used by movement actions (but they may be used for selection).

handleMovementKey

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(android.widget.TextView, android.text.Spannable, int, android.view.KeyEvent) calls this method once to handle an KeyEvent.ACTION_DOWN. onKeyOther(android.widget.TextView, android.text.Spannable, android.view.KeyEvent) calls this method repeatedly to handle each repetition of an KeyEvent.ACTION_MULTIPLE.

protected boolean home (TextView widget, 
                Spannable buffer)
