Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constants

public static final int ACTION_HOVER_ENTER

Constant for getActionMasked(MotionEvent): The pointer is not down but has entered the boundaries of a window or view.

This action is always delivered to the window or view under the pointer.

This action is not a touch event so it is delivered to onGenericMotionEvent(MotionEvent) rather than onTouchEvent(MotionEvent).

Constant Value: 9 (0x00000009)

public static final int ACTION_HOVER_EXIT

Constant for getActionMasked(MotionEvent): The pointer is not down but has exited the boundaries of a window or view.

This action is always delivered to the window or view that was previously under the pointer.

This action is not a touch event so it is delivered to onGenericMotionEvent(MotionEvent) rather than onTouchEvent(MotionEvent).

Constant Value: 10 (0x0000000a)

public static final int ACTION_HOVER_MOVE

Synonym for ACTION_HOVER_MOVE.

Constant Value: 7 (0x00000007)

public static final int ACTION_MASK

Synonym for ACTION_MASK.

Constant Value: 255 (0x000000ff)

public static final int ACTION_POINTER_DOWN

Synonym for ACTION_POINTER_DOWN.

Constant Value: 5 (0x00000005)

public static final int ACTION_POINTER_INDEX_MASK

Synonym for ACTION_POINTER_INDEX_MASK.

Constant Value: 65280 (0x0000ff00)

public static final int ACTION_POINTER_INDEX_SHIFT

Synonym for ACTION_POINTER_INDEX_SHIFT.

Constant Value: 8 (0x00000008)

public static final int ACTION_POINTER_UP

Synonym for ACTION_POINTER_UP.

Constant Value: 6 (0x00000006)

public static final int ACTION_SCROLL

Synonym for ACTION_SCROLL.

Constant Value: 8 (0x00000008)

Call findPointerIndex(int). If running on a pre-ECLAIR device, does nothing and returns -1.

public static int getActionIndex (MotionEvent event)

Call getAction(), returning only the pointer index portion

public static int getActionMasked (MotionEvent event)

Call getAction(), returning only the ACTION_MASK portion.

public static int getPointerCount (MotionEvent event)

The number of pointers of data contained in this event. Always >= 1.

public static int getPointerId (MotionEvent event, int pointerIndex)

Call getPointerId(int). If running on a pre-ECLAIR device, IndexOutOfBoundsException is thrown.

public static float getX (MotionEvent event, int pointerIndex)

Call getX(int). If running on a pre-ECLAIR device, IndexOutOfBoundsException is thrown.

public static float getY (MotionEvent event, int pointerIndex)

Call getY(int). If running on a pre-ECLAIR device, IndexOutOfBoundsException is thrown.
