GeolocationCoordinates interface represents the position and altitude of the device on Earth, as well as the accuracy with which these properties are calculated.

特性

GeolocationCoordinates interface doesn't inherit any properties .

GeolocationCoordinates.latitude 只读 安全上下文

返回 double representing the position's latitude in decimal degrees.

GeolocationCoordinates.longitude 只读 安全上下文

返回 double representing the position's longitude in decimal degrees.

GeolocationCoordinates.altitude 只读 安全上下文

返回 double representing the position's altitude in meters, relative to sea level. This value can be null if the implementation cannot provide the data.

GeolocationCoordinates.accuracy 只读 安全上下文

返回 double representing the accuracy of the latitude and longitude properties, expressed in meters.

GeolocationCoordinates.altitudeAccuracy 只读 安全上下文

返回 double representing the accuracy of the altitude expressed in meters. This value can be null .

GeolocationCoordinates.heading 只读 安全上下文

返回 double representing the direction towards which the device is facing. This value, specified in degrees, indicates how far off from heading true north the device is. 0 degrees represents true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees). If speed is 0 , heading is NaN . If the device is unable to provide heading information, this value is null .

GeolocationCoordinates.speed 只读 安全上下文

返回 double representing the velocity of the device in meters per second. This value can be null .

方法

GeolocationCoordinates interface neither implements, nor inherits any method.
