Public Constructors

public MotionEventCompat ()

Public Methods

public static int findPointerIndex (MotionEvent event, int pointerId)

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 float getAxisValue (MotionEvent event, int axis, int pointerIndex)

Returns the value of the requested axis for the given pointer index (use getPointerId(MotionEvent, int) to find the pointer identifier for this index).

Parameters
axis The axis identifier for the axis value to retrieve.
pointerIndex Raw index of pointer to retrieve. Value may be from 0 (the first pointer that is down) to getPointerCount(MotionEvent)-1.
Returns
  • The value of the axis, or 0 if the axis is not available.
See Also

public static float getAxisValue (MotionEvent event, int axis)

Get axis value for the first pointer index (may be an arbitrary pointer identifier).

Parameters
axis The axis identifier for the axis value to retrieve.
See Also

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 int getSource (MotionEvent event)

Gets the source of the event.

Returns

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.
