Inherited functions

From class BaseMovementMethod Boolean canSelectArbitrarily() Int getMovementMetaState(buffer: Spannable!, event: KeyEvent!) 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). Boolean handleMovementKey(widget: TextView!, buffer: Spannable!, keyCode: Int, movementMetaState: Int, event: KeyEvent!) Performs a movement key action. The default implementation decodes the key down and invokes movement actions such as down and up. 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. Unit initialize(widget: TextView!, text: Spannable!) Boolean nextParagraph(widget: TextView, buffer: Spannable) Performs a next paragraph movement action. Boolean onGenericMotionEvent(widget: TextView!, text: Spannable!, event: MotionEvent!) Boolean onKeyDown(widget: TextView!, text: Spannable!, keyCode: Int, event: KeyEvent!) Boolean onKeyOther(widget: TextView!, text: Spannable!, event: KeyEvent!) Boolean onKeyUp(widget: TextView!, text: Spannable!, keyCode: Int, event: KeyEvent!) Boolean onTrackballEvent(widget: TextView!, text: Spannable!, event: MotionEvent!) Boolean previousParagraph(widget: TextView, buffer: Spannable) Performs a previous paragraph movement action.
