public int detail

The gesture type.

This field determines the GestureEvent fields that contain valid data.
doitback to summary
public boolean doit

This flag indicates whether the operation should be allowed. Setting it to false will cancel the operation.

magnificationback to summary
public double magnification

This field is valid when the detail field is set to GESTURE_MAGNIFY. This is the scale factor to be applied. This value will be 1.0 in the first received event with GESTURE_MAGNIFY, and will then fluctuate in subsequent events as the user moves their fingers.

rotationback to summary
public double rotation

This field is valid when the detail field is set to GESTURE_ROTATE. It specifies the number of degrees rotated on the device since the gesture started. Positive values indicate counter-clockwise rotation, and negative values indicate clockwise rotation.

xback to summary
public int x

The meaning of this field is dependent on the value of the detail field and the platform. It can represent either the x coordinate of the centroid of the touches that make up the gesture, or the x coordinate of the cursor at the time the gesture was performed.

xDirectionback to summary
public int xDirection

This field is valid when the detail field is set to GESTURE_SWIPE or GESTURE_PAN. Both xDirection and yDirection can be valid for an individual gesture. The meaning of this field is dependent on the value of the detail field.

If detail is GESTURE_SWIPE then a positive value indicates a swipe to the right and a negative value indicates a swipe to the left. If detail is GESTURE_PAN then a positive value indicates a pan to the right by this field's count of points and a negative value indicates a pan to the left by this field's count of points.

yback to summary
public int y

The meaning of this field is dependent on the value of the detail field and the platform. It can represent either the y coordinate of the centroid of the touches that make up the gesture, or the y coordinate of the cursor at the time the gesture was performed.

yDirectionback to summary
public int yDirection

This field is valid when the detail field is set to GESTURE_SWIPE or GESTURE_PAN. Both xDirection and yDirection can be valid for an individual gesture. The meaning of this field is dependent on the value of the detail field. If detail is GESTURE_SWIPE then a positive value indicates a downward swipe and a negative value indicates an upward swipe. If detail is GESTURE_PAN then a positive value indicates a downward pan by this field's count of points and a negative value indicates an upward pan by this field's count of points.
