  • onMeasure

    public void onMeasure(int widthMeasureSpec,
                 int heightMeasureSpec)

    Description copied from class: View

    Measure the view and its content to determine the measured width and the measured height. This method is invoked by View.measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents.

    CONTRACT: When overriding this method, you must call View.setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by View.measure(int, int). Calling the superclass' View.onMeasure(int, int) is a valid use.

    The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override View.onMeasure(int, int) to provide better measurements of their content.

    If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (View.getSuggestedMinimumHeight() and View.getSuggestedMinimumWidth()).

    Overrides:

    onMeasure in class View

    Parameters:

    widthMeasureSpec - horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

    heightMeasureSpec - vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.

    See Also:

    View.getMeasuredWidth(), View.getMeasuredHeight(), View.setMeasuredDimension(int, int), View.getSuggestedMinimumHeight(), View.getSuggestedMinimumWidth(), View.MeasureSpec.getMode(int), View.MeasureSpec.getSize(int)

  • onSizeChanged

    public void onSizeChanged(int w,
                     int h,
                     int oldw,
                     int oldh)

    Description copied from class: View
    This is called during layout when the size of this view has changed. If you were just added to the view hierarchy, you're called with the old values of 0.

    Overrides:

    onSizeChanged in class View

    Parameters:

    w - Current width of this view.

    h - Current height of this view.

    oldw - Old width of this view.

    oldh - Old height of this view.

  • onDraw

    public void onDraw(Canvas canvas)

    Description copied from class: View
    Implement this to do your drawing.

    Overrides:

    onDraw in class View

    Parameters:

    canvas - the canvas on which the background will be drawn

  • invalidateAllKeys

    public void invalidateAllKeys()

    Requests a redraw of the entire keyboard. Calling View.invalidate(android.graphics.Rect) is not sufficient because the keyboard renders the keys to an off-screen buffer and an invalidate() only draws the cached buffer.

    See Also:

    invalidateKey(int)

  • invalidateKey

    public void invalidateKey(int keyIndex)

    Invalidates a key so that it will be redrawn on the next repaint. Use this method if only one key is changing it's content. Any changes that affect the position or size of the key may not be honored.

    Parameters:

    keyIndex - the index of the key in the attached Keyboard.

    See Also:

    invalidateAllKeys()

  • onLongPress

    protected boolean onLongPress(Keyboard.Key popupKey)

    Called when a key is long pressed. By default this will open any popup keyboard associated with this key through the attributes popupLayout and popupCharacters.

    Parameters:

    popupKey - the key that was long pressed

    Returns:

    true if the long press is handled, false otherwise. Subclasses should call the method on the base class if the subclass doesn't wish to handle the call.

  • onHoverEvent

    public boolean onHoverEvent(MotionEvent event)

    Description copied from class: View
    Implement this method to handle hover events.

    This method is called whenever a pointer is hovering into, over, or out of the bounds of a view and the view is not currently being touched. Hover events are represented as pointer events with action MotionEvent.ACTION_HOVER_ENTER, MotionEvent.ACTION_HOVER_MOVE, or MotionEvent.ACTION_HOVER_EXIT.

    • The view receives a hover event with action MotionEvent.ACTION_HOVER_ENTER when the pointer enters the bounds of the view.
    • The view receives a hover event with action MotionEvent.ACTION_HOVER_MOVE when the pointer has already entered the bounds of the view and has moved.
    • The view receives a hover event with action MotionEvent.ACTION_HOVER_EXIT when the pointer has exited the bounds of the view or when the pointer is about to go down due to a button click, tap, or similar user action that causes the view to be touched.

    The view should implement this method to return true to indicate that it is handling the hover event, such as by changing its drawable state.

    The default implementation calls View.setHovered(boolean) to update the hovered state of the view when a hover enter or hover exit event is received, if the view is enabled and is clickable. The default implementation also sends hover accessibility events.

    Overrides:

    onHoverEvent in class View

    Parameters:

    event - The motion event that describes the hover.

    Returns:

    True if the view handled the hover event.

    See Also:

    View.isHovered(), View.setHovered(boolean), View.onHoverChanged(boolean)

  • onTouchEvent

    public boolean onTouchEvent(MotionEvent me)

    Description copied from class: View
    Implement this method to handle touch screen motion events.

    Overrides:

    onTouchEvent in class View

    Parameters:

    me - The motion event.

    Returns:

    True if the event was handled, false otherwise.

  • swipeRight

    protected void swipeRight()

  • swipeLeft

    protected void swipeLeft()

  • swipeUp

    protected void swipeUp()

  • swipeDown

    protected void swipeDown()

  • closing

    public void closing()

  • onDetachedFromWindow

    public void onDetachedFromWindow()

    Description copied from class: View
    This is called when the view is detached from a window. At this point it no longer has a surface for drawing.

    Overrides:

    onDetachedFromWindow in class View

    See Also:

    View.onAttachedToWindow()

  • handleBack

    public boolean handleBack()
