Enumeration Type Documentation

anonymous enum

Motion event edge touch flags.

Enumerator
AMOTION_EVENT_EDGE_FLAG_NONE	No edges intersected.
AMOTION_EVENT_EDGE_FLAG_TOP	Flag indicating the motion event intersected the top edge of the screen.
AMOTION_EVENT_EDGE_FLAG_BOTTOM	Flag indicating the motion event intersected the bottom edge of the screen.
AMOTION_EVENT_EDGE_FLAG_LEFT	Flag indicating the motion event intersected the left edge of the screen.
AMOTION_EVENT_EDGE_FLAG_RIGHT	Flag indicating the motion event intersected the right edge of the screen.

anonymous enum

Constants that identify each individual axis of a motion event.

Enumerator
AMOTION_EVENT_AXIS_X	Axis constant: X axis of a motion event. For a touch screen, reports the absolute X screen position of the center of the touch contact area. The units are display pixels. For a touch pad, reports the absolute X surface position of the center of the touch contact area. The units are device-dependent. For a mouse, reports the absolute X screen position of the mouse pointer. The units are display pixels. For a trackball, reports the relative horizontal displacement of the trackball. The value is normalized to a range from -1.0 (left) to 1.0 (right). For a joystick, reports the absolute X position of the joystick. The value is normalized to a range from -1.0 (left) to 1.0 (right).
AMOTION_EVENT_AXIS_Y	Axis constant: Y axis of a motion event. For a touch screen, reports the absolute Y screen position of the center of the touch contact area. The units are display pixels. For a touch pad, reports the absolute Y surface position of the center of the touch contact area. The units are device-dependent. For a mouse, reports the absolute Y screen position of the mouse pointer. The units are display pixels. For a trackball, reports the relative vertical displacement of the trackball. The value is normalized to a range from -1.0 (up) to 1.0 (down). For a joystick, reports the absolute Y position of the joystick. The value is normalized to a range from -1.0 (up or far) to 1.0 (down or near).
AMOTION_EVENT_AXIS_PRESSURE	Axis constant: Pressure axis of a motion event. For a touch screen or touch pad, reports the approximate pressure applied to the surface by a finger or other tool. The value is normalized to a range from 0 (no pressure at all) to 1 (normal pressure), although values higher than 1 may be generated depending on the calibration of the input device. For a trackball, the value is set to 1 if the trackball button is pressed or 0 otherwise. For a mouse, the value is set to 1 if the primary mouse button is pressed or 0 otherwise.
AMOTION_EVENT_AXIS_SIZE	Axis constant: Size axis of a motion event. For a touch screen or touch pad, reports the approximate size of the contact area in relation to the maximum detectable size for the device. The value is normalized to a range from 0 (smallest detectable size) to 1 (largest detectable size), although it is not a linear scale. This value is of limited use. To obtain calibrated size information, see AMOTION_EVENT_AXIS_TOUCH_MAJOR or AMOTION_EVENT_AXIS_TOOL_MAJOR.
AMOTION_EVENT_AXIS_TOUCH_MAJOR	Axis constant: TouchMajor axis of a motion event. For a touch screen, reports the length of the major axis of an ellipse that represents the touch area at the point of contact. The units are display pixels. For a touch pad, reports the length of the major axis of an ellipse that represents the touch area at the point of contact. The units are device-dependent.
AMOTION_EVENT_AXIS_TOUCH_MINOR	Axis constant: TouchMinor axis of a motion event. For a touch screen, reports the length of the minor axis of an ellipse that represents the touch area at the point of contact. The units are display pixels. For a touch pad, reports the length of the minor axis of an ellipse that represents the touch area at the point of contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another.
AMOTION_EVENT_AXIS_TOOL_MAJOR	Axis constant: ToolMajor axis of a motion event. For a touch screen, reports the length of the major axis of an ellipse that represents the size of the approaching finger or tool used to make contact. For a touch pad, reports the length of the major axis of an ellipse that represents the size of the approaching finger or tool used to make contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another. The tool size may be larger than the touch size since the tool may not be fully in contact with the touch sensor.
AMOTION_EVENT_AXIS_TOOL_MINOR	Axis constant: ToolMinor axis of a motion event. For a touch screen, reports the length of the minor axis of an ellipse that represents the size of the approaching finger or tool used to make contact. For a touch pad, reports the length of the minor axis of an ellipse that represents the size of the approaching finger or tool used to make contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another. The tool size may be larger than the touch size since the tool may not be fully in contact with the touch sensor.
AMOTION_EVENT_AXIS_ORIENTATION	Axis constant: Orientation axis of a motion event. For a touch screen or touch pad, reports the orientation of the finger or tool in radians relative to the vertical plane of the device. An angle of 0 radians indicates that the major axis of contact is oriented upwards, is perfectly circular or is of unknown orientation. A positive angle indicates that the major axis of contact is oriented to the right. A negative angle indicates that the major axis of contact is oriented to the left. The full range is from -PI/2 radians (finger pointing fully left) to PI/2 radians (finger pointing fully right). For a stylus, the orientation indicates the direction in which the stylus is pointing in relation to the vertical axis of the current orientation of the screen. The range is from -PI radians to PI radians, where 0 is pointing up, -PI/2 radians is pointing left, -PI or PI radians is pointing down, and PI/2 radians is pointing right. See also AMOTION_EVENT_AXIS_TILT.

anonymous enum

Key event actions.

Enumerator
AKEY_EVENT_ACTION_DOWN	The key has been pressed down.
AKEY_EVENT_ACTION_UP	The key has been released.
AKEY_EVENT_ACTION_MULTIPLE	Multiple duplicate key events have occurred in a row, or a complex string is being delivered. The repeat_count property of the key event contains the number of times the given key code should be executed.

anonymous enum

Key event flags.

Enumerator
AKEY_EVENT_FLAG_WOKE_HERE	This mask is set if the device woke because of this key event.
AKEY_EVENT_FLAG_SOFT_KEYBOARD	This mask is set if the key event was generated by a software keyboard.
AKEY_EVENT_FLAG_KEEP_TOUCH_MODE	This mask is set if we don't want the key event to cause us to leave touch mode.
AKEY_EVENT_FLAG_FROM_SYSTEM	This mask is set if an event was known to come from a trusted part of the system. That is, the event is known to come from the user, and could not have been spoofed by a third party component.
AKEY_EVENT_FLAG_EDITOR_ACTION	This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done". This allows TextView to dispatch these as normal enter keys for old applications, but still do the appropriate action when receiving them.
AKEY_EVENT_FLAG_CANCELED	When associated with up key events, this indicates that the key press has been canceled. Typically this is used with virtual touch screen keys, where the user can slide from the virtual key area on to the display: in that case, the application will receive a canceled up event and should not perform the action normally associated with the key. Note that for this to work, the application can not perform an action for a key until it receives an up or the long press timeout has expired.
AKEY_EVENT_FLAG_VIRTUAL_HARD_KEY	This key event was generated by a virtual (on-screen) hard key area. Typically this is an area of the touchscreen, outside of the regular display, dedicated to "hardware" buttons.
AKEY_EVENT_FLAG_LONG_PRESS	This flag is set for the first key repeat that occurs after the long press timeout.
AKEY_EVENT_FLAG_CANCELED_LONG_PRESS	Set when a key event has AKEY_EVENT_FLAG_CANCELED set because a long press action was executed while it was down.
AKEY_EVENT_FLAG_TRACKING	Set for AKEY_EVENT_ACTION_UP when this event's key code is still being tracked from its initial down. That is, somebody requested that tracking started on the key down and a long press has not caused the tracking to be canceled.
AKEY_EVENT_FLAG_FALLBACK	Set when a key event has been synthesized to implement default behavior for an event that the application did not handle. Fallback key events are generated by unhandled trackball motions (to emulate a directional keypad) and by certain unhandled key presses that are declared in the key map (such as special function numeric keypad keys when numlock is off).

anonymous enum

Motion event actions

Enumerator
AMOTION_EVENT_ACTION_MASK	Bit mask of the parts of the action code that are the action itself.
AMOTION_EVENT_ACTION_POINTER_INDEX_MASK	Bits in the action code that represent a pointer index, used with AMOTION_EVENT_ACTION_POINTER_DOWN and AMOTION_EVENT_ACTION_POINTER_UP. Shifting down by AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT provides the actual pointer index where the data for the pointer going up or down can be found.
AMOTION_EVENT_ACTION_DOWN	A pressed gesture has started, the motion contains the initial starting location.
AMOTION_EVENT_ACTION_UP	A pressed gesture has finished, the motion contains the final release location as well as any intermediate points since the last down or move event.
AMOTION_EVENT_ACTION_MOVE	A change has happened during a press gesture (between AMOTION_EVENT_ACTION_DOWN and AMOTION_EVENT_ACTION_UP). The motion contains the most recent point, as well as any intermediate points since the last down or move event.
AMOTION_EVENT_ACTION_CANCEL	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.
AMOTION_EVENT_ACTION_OUTSIDE	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.
AMOTION_EVENT_ACTION_POINTER_DOWN	A non-primary pointer has gone down. The bits in AMOTION_EVENT_ACTION_POINTER_INDEX_MASK indicate which pointer changed.
AMOTION_EVENT_ACTION_POINTER_UP	A non-primary pointer has gone up. The bits in AMOTION_EVENT_ACTION_POINTER_INDEX_MASK indicate which pointer changed.
AMOTION_EVENT_ACTION_HOVER_MOVE	A change happened but the pointer is not down (unlike AMOTION_EVENT_ACTION_MOVE). The motion contains the most recent point, as well as any intermediate points since the last hover move event.
AMOTION_EVENT_ACTION_SCROLL	The motion event contains relative vertical and/or horizontal scroll offsets. Use getAxisValue to retrieve the information from AMOTION_EVENT_AXIS_VSCROLL and AMOTION_EVENT_AXIS_HSCROLL. The pointer may or may not be down when this event is dispatched. This action is always delivered to the winder under the pointer, which may not be the window currently touched.
AMOTION_EVENT_ACTION_HOVER_ENTER	The pointer is not down but has entered the boundaries of a window or view.
AMOTION_EVENT_ACTION_HOVER_EXIT	The pointer is not down but has exited the boundaries of a window or view.

anonymous enum

Motion event flags.

Enumerator

AMOTION_EVENT_FLAG_WINDOW_IS_OBSCURED

This flag indicates that the window that received this motion event is partly or wholly obscured by another visible window above it. This flag is set to true even if the event did not directly pass through the obscured area. A security sensitive application can check this flag to identify situations in which a malicious application may have covered up part of its content for the purpose of misleading the user or hijacking touches. An appropriate response might be to drop the suspect touches or to take additional precautions to confirm the user's actual intent.

Function Documentation

int32_t AInputEvent_getDeviceId

(

const AInputEvent *

event

)

Get the id for the device that an input event came from.

Input events can be generated by multiple different input devices. Use the input device id to obtain information about the input device that was responsible for generating a particular event.

An input device id of 0 indicates that the event didn't come from a physical device; other numbers are arbitrary and you shouldn't depend on the values. Use the provided input device query API to obtain information about input devices.

const AInputEvent *

event

)

Get the input event source.

int32_t AInputEvent_getType
