From class BaseMovementMethod
Boolean |
canSelectArbitrarily()
Returns true if this movement method allows arbitrary selection of any text; false if it has no selection (like a movement method that only scrolls) or a constrained selection (for example limited to links. The "Select All" menu item is disabled if arbitrary selection is not allowed.
|
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!)
If the key listener wants to other kinds of key events, return true, otherwise return false and the caller (i.e. the widget host) will handle the key.
|
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.
