Method Detail

distance

public static double distance(double oneLat,
                              double oneLng,
                              double anotherLat,
                              double anotherLng)

Computes the distance between two points.

Parameters:

oneLat - the latitude of one point

oneLng - the longitude of that point

anotherLat - the latitude of another point

anotherLng - the longitude of that other point

Returns:

the distance between the two points, in meters

distance

public static double distance(com.google.android.gms.maps.model.LatLng one,
                              com.google.android.gms.maps.model.LatLng another)

Computes the distance between two points represented as LatLngs.

Parameters:

one - one latitude-longitude coordinate pair

another - the other latitude-longitude coordinate pair

Returns:

the distance between the two points, in meters

same

public static boolean same(double one,
                           double another)

Determines whether two location-related coordinates are similar enough to be considered the same.

Parameters:

one - a coordinate of one point

another - the corresponding coordinate of the other point

Returns:

whether they're effectively the same coordinate

same

public static boolean same(double oneLat,
                           double oneLng,
                           double anotherLat,
                           double anotherLng)

Determines whether two points are similar enough to be considered the same spot.

Parameters:

oneLat - the latitude of one point

oneLng - the longitude of that point

anotherLat - the latitude of another point

anotherLng - the longitude of that other point

Returns:

whether they're the same place

same

public static boolean same(com.google.android.gms.maps.model.LatLng one,
                           com.google.android.gms.maps.model.LatLng another)

Determines whether two points are similar enough to be considered the same spot.

Parameters:

one - one point

another - the other point

Returns:

whether they're the same place
