public final class MotionEvent

extends InputEvent implements Parcelable

Object used to report movement (mouse, pen, finger, trackball) events. Motion events may hold either absolute or relative movements and other data, depending on the type of device.

Motion events describe movements in terms of an action code and a set of axis values. The action code specifies the state change that occurred such as a pointer going down or up. The axis values describe the position and other movement properties.

For example, when the user first touches the screen, the system delivers a touch event to the appropriate View with the action code ACTION_DOWN and a set of axis values that include the X and Y coordinates of the touch and information about the pressure, size and orientation of the contact area.

Some devices can report multiple movement traces at the same time. Multi-touch screens emit one movement trace for each finger. The individual fingers or other objects that generate movement traces are referred to as pointers. Motion events contain information about all of the pointers that are currently active even if some of them have not moved since the last event was delivered.

The number of pointers only ever changes by one as individual pointers go up and down, except when the gesture is canceled.

Each pointer has a unique id that is assigned when it first goes down (indicated by ACTION_DOWN or ACTION_POINTER_DOWN ). A pointer id remains valid until the pointer eventually goes up (indicated by ACTION_UP or ACTION_POINTER_UP ) or when the gesture is canceled (indicated by ACTION_CANCEL ).

The MotionEvent class provides many methods to query the position and other properties of pointers, such as getX(int) , getY(int) , getAxisValue(int) , getPointerId(int) , getToolType(int) , and many others. Most of these methods accept the pointer index as a parameter rather than the pointer id. The pointer index of each pointer in the event ranges from 0 to one less than the value returned by getPointerCount() .

The order in which individual pointers appear within a motion event is undefined. Thus the pointer index of a pointer can change from one event to the next but the pointer id of a pointer is guaranteed to remain constant as long as the pointer remains active. Use the getPointerId(int) method to obtain the pointer id of a pointer to track it across all subsequent motion events in a gesture. Then for successive motion events, use the findPointerIndex(int) method to obtain the pointer index for a given pointer id in that motion event.

Mouse and stylus buttons can be retrieved using getButtonState() . It is a good idea to check the button state while handling ACTION_DOWN as part of a touch event. The application may choose to perform some different action if the touch event starts due to a secondary button click, such as presenting a context menu.

For efficiency, motion events with ACTION_MOVE may batch together multiple movement samples within a single object. The most current pointer coordinates are available using getX(int) and getY(int) . Earlier coordinates within the batch are accessed using getHistoricalX(int, int) and getHistoricalY(int, int) . The coordinates are "historical" only insofar as they are older than the current coordinates in the batch; however, they are still distinct from any other coordinates reported in prior motion events. To process all coordinates in the batch in time order, first consume the historical coordinates then consume the current coordinates.

Example: Consuming all samples for all pointers in a motion event in time order.

The interpretation of the contents of a MotionEvent varies significantly depending on the source class of the device.

On pointing devices with source class InputDevice#SOURCE_CLASS_POINTER such as touch screens, the pointer coordinates specify absolute positions such as view X/Y coordinates. Each complete gesture is represented by a sequence of motion events with actions that describe pointer state transitions and movements. A gesture starts with a motion event with ACTION_DOWN that provides the location of the first pointer down. As each additional pointer that goes down or up, the framework will generate a motion event with ACTION_POINTER_DOWN or ACTION_POINTER_UP accordingly. Pointer movements are described by motion events with ACTION_MOVE . Finally, a gesture end either when the final pointer goes up as represented by a motion event with ACTION_UP or when gesture is canceled with ACTION_CANCEL .

Some pointing devices such as mice may support vertical and/or horizontal scrolling. A scroll event is reported as a generic motion event with ACTION_SCROLL that includes the relative scroll offset in the AXIS_VSCROLL and AXIS_HSCROLL axes. See getAxisValue(int) for information about retrieving these additional axes.

On trackball devices with source class InputDevice#SOURCE_CLASS_TRACKBALL , the pointer coordinates specify relative movements as X/Y deltas. A trackball gesture consists of a sequence of movements described by motion events with ACTION_MOVE interspersed with occasional ACTION_DOWN or ACTION_UP motion events when the trackball button is pressed or released.

On joystick devices with source class InputDevice#SOURCE_CLASS_JOYSTICK , the pointer coordinates specify the absolute position of the joystick axes. The joystick axis values are normalized to a range of -1.0 to 1.0 where 0.0 corresponds to the center position. More information about the set of available axes and the range of motion can be obtained using InputDevice#getMotionRange . Some common joystick axes are AXIS_X , AXIS_Y , AXIS_HAT_X , AXIS_HAT_Y , AXIS_Z and AXIS_RZ .

Refer to InputDevice for more information about how different kinds of input devices and sources represent pointer coordinates.

Motion events are always delivered to views as a consistent stream of events. What constitutes a consistent stream varies depending on the type of device. For touch events, consistency implies that pointers go down one at a time, move around as a group and then go up one at a time or are canceled.

While the framework tries to deliver consistent streams of motion events to views, it cannot guarantee it. Some events may be dropped or modified by containing views in the application before they are delivered thereby making the stream of events inconsistent. Views should always be prepared to handle ACTION_CANCEL and should tolerate anomalous situations such as receiving a new ACTION_DOWN without first having received an ACTION_UP for the prior gesture.

Constants

ACTION_BUTTON_PRESS Added in API level 23 public static final int ACTION_BUTTON_PRESS Constant for getActionMasked() : A button has been pressed. Use getActionButton() to get which button was pressed. This action is not a touch event so it is delivered to View#onGenericMotionEvent(MotionEvent) rather than View#onTouchEvent(MotionEvent) . Constant Value: 11 (0x0000000b)

ACTION_BUTTON_RELEASE Added in API level 23 public static final int ACTION_BUTTON_RELEASE Constant for getActionMasked() : A button has been released.

Constant Value: 12 (0x0000000c)

ACTION_CANCEL Added in API level 1 public static final int ACTION_CANCEL Constant for getActionMasked() : The current gesture has been aborted. You will not receive any more points in it. You should treat this as an up event, but not perform any action that you normally would. Constant Value: 3 (0x00000003)

ACTION_DOWN Added in API level 1 public static final int ACTION_DOWN Constant for getActionMasked() : A pressed gesture has started, the motion contains the initial starting location. This is also a good time to check the button state to distinguish secondary and tertiary button clicks and handle them appropriately. Use getButtonState() to retrieve the button state. Constant Value: 0 (0x00000000)

ACTION_HOVER_ENTER Added in API level 14 public static final int ACTION_HOVER_ENTER Constant for getActionMasked() : 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 View#onGenericMotionEvent(MotionEvent) rather than View#onTouchEvent(MotionEvent) . Constant Value: 9 (0x00000009)

ACTION_HOVER_EXIT Added in API level 14 public static final int ACTION_HOVER_EXIT Constant for getActionMasked() : 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 View#onGenericMotionEvent(MotionEvent) rather than View#onTouchEvent(MotionEvent) . Constant Value: 10 (0x0000000a)

ACTION_HOVER_MOVE Added in API level 12 public static final int ACTION_HOVER_MOVE Constant for getActionMasked() : A change happened but the pointer is not down (unlike ACTION_MOVE ). The motion contains the most recent point, as well as any intermediate points since the last hover move event. 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 View#onGenericMotionEvent(MotionEvent) rather than View#onTouchEvent(MotionEvent) . Constant Value: 7 (0x00000007)

ACTION_MOVE Added in API level 1 public static final int ACTION_MOVE Constant for getActionMasked() : A change has happened during a press gesture (between ACTION_DOWN and ACTION_UP ). The motion contains the most recent point, as well as any intermediate points since the last down or move event. Constant Value: 2 (0x00000002)

ACTION_OUTSIDE Added in API level 3 public static final int ACTION_OUTSIDE Constant for getActionMasked() : A movement has happened outside of the normal bounds of the UI element. This does not provide a full gesture, but only the initial location of the movement/touch. Note: Because the location of any event will be outside the bounds of the view hierarchy, it will not get dispatched to any children of a ViewGroup by default. Therefore, movements with ACTION_OUTSIDE should be handled in either the root View or in the appropriate Window.Callback (e.g. Activity or Dialog ). Constant Value: 4 (0x00000004)

Protected methods

finalize Added in API level 1 protected void finalize () Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup. The general contract of finalize is that it is invoked if and when the Java™ virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize , however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded. The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition. The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates. After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded. The finalize method is never invoked more than once by a Java virtual machine for any given object. Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored. Throws Throwable
