Struct android_activity::input::MotionEvent

pub struct MotionEvent<'a> { /* private fields */ }

A motion event

For general discussion of motion events in Android, see the relevant javadoc.

Implementations

impl<'a> MotionEvent<'a>

pub fn source(&self) -> Source

Get the source of the event.

pub fn device_id(&self) -> i32

Get the device id associated with the event.

pub fn action(&self) -> MotionAction

Returns the motion action associated with the event.

See the MotionEvent docs

pub fn action_button(&self) -> Button

Returns which button has been modified during a press or release action.

For actions other than MotionAction::ButtonPress and MotionAction::ButtonRelease the returned value is undefined.

See the MotionEvent docs

pub fn pointer_index(&self) -> usize

Returns the pointer index of an Up or Down event.

Pointer indices can change per motion event. For an identifier that stays the same, see Pointer::pointer_id().

This only has a meaning when the action is one of Up, Down, PointerUp, or PointerDown.

pub fn pointer_count(&self) -> usize

Returns the number of pointers in this event

See the MotionEvent docs

pub fn pointers(&self) -> PointersIter<'_>

An iterator over the pointers in this motion event

pub fn pointer_at_index(&self, index: usize) -> Pointer<'_>

The pointer at a given pointer index. Panics if the pointer index is out of bounds.

If you need to loop over all the pointers, prefer the pointers() method.

pub fn meta_state(&self) -> MetaState

Returns the state of any modifier keys that were pressed during the event.

See the NDK docs

pub fn button_state(&self) -> ButtonState

Returns the button state during this event, as a bitfield.

See the NDK docs

pub fn down_time(&self) -> i64

Returns the time of the start of this gesture, in the java.lang.System.nanoTime() time base

See the NDK docs

pub fn edge_flags(&self) -> EdgeFlags

Returns a bitfield indicating which edges were touched by this event.

See the NDK docs

pub fn event_time(&self) -> i64

Returns the time of this event, in the java.lang.System.nanoTime() time base

See the NDK docs

pub fn flags(&self) -> MotionEventFlags

The flags associated with a motion event.

See the NDK docs

pub fn x_precision(&self) -> f32

Returns the precision of the x value of the coordinates

See the NDK docs

pub fn y_precision(&self) -> f32

Returns the precision of the y value of the coordinates

See the NDK docs

Trait Implementations

impl<'a> Debug for MotionEvent<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
