Coordinates

Coordinates （坐标）接口表示设备在地球上的位置和海拔，以及计算这些属性的精确度。

属性

The Coordinates interface doesn't inherit any property.

Coordinates.latitude 只读: Returns a double representing the position's latitude in decimal degrees.
Coordinates.longitude (en-US) 只读: Returns a double representing the position's longitude in decimal degrees.
Coordinates.altitude (en-US) 只读: Returns a double representing the position's altitude in metres, relative to sea level. This value can be null if the implementation cannot provide the data.
Coordinates.accuracy (en-US) 只读: Returns a double representing the accuracy of the latitude and longitude properties, expressed in meters.
Coordinates.altitudeAccuracy (en-US) 只读: Returns a double representing the accuracy of the altitude expressed in meters. This value can be null.
Coordinates.heading (en-US) 只读: Returns a double representing the direction in which the device is traveling. This value, specified in degrees, indicates how far off from heading due north the device is. 0 degrees represents true 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.
Coordinates.speed (en-US) 只读: Returns a double representing the velocity of the device in meters per second. This value can be null.

The Coordinates interface neither implements, nor inherits any method.
