android 计算距离,android – 计算两个地理位置之间的距离

http://developer.android.com/reference/android/location/Location.html

看看distanceTo或distanceBetween。您可以从纬度和经度创建位置对象：

Location locationA = new Location("point A");

locationA.setLatitude(latA);

locationA.setLongitude(lngA);

Location locationB = new Location("point B");

locationB.setLatitude(latB);

locationB.setLongitude(lngB);

float distance = locationA.distanceTo(locationB);

要么

private double meterDistanceBetweenPoints(float lat_a, float lng_a, float lat_b, float lng_b) {

float pk = (float) (180.f/Math.PI);

float a1 = lat_a / pk;

float a2 = lng_a / pk;

float b1 = lat_b / pk;

float b2 = lng_b / pk;

float t1 = FloatMath.cos(a1)*FloatMath.cos(a2)*FloatMath.cos(b1)*FloatMath.cos(b2);

float t2 = FloatMath.cos(a1)*FloatMath.sin(a2)*FloatMath.cos(b1)*FloatMath.sin(b2);

float t3 = FloatMath.sin(a1)*FloatMath.sin(b1);

double tt = Math.acos(t1 + t2 + t3);

return 6366000*tt;

}
