Look into distanceTo or distanceBetween. You can create a Location object from a latitude and longitude:

<pre><code>Location location = new Location("");
location.setLatitude(lat);
location.setLongitude(lon);
</code></pre>

blocks|key|5531355|text|如上所述，Location类是最好的选择。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5531356|下面是我使用的代码：|5531357|Location+locationA+=+new+Location("point+A");++

locationA.setLatitude(pointA.getLatitudeE6()+/+1E6);++
locationA.setLongitude(pointB.getLongitudeE6()+/+1E6);++

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

locationB.setLatitude(pointB.getLatitudeE6()+/+1E6);++
locationB.setLongitude(pointB.getLongitudeE6()+/+1E6);++

double+distance+=+locationA.distanceTo(locationB);|code-block|syntax|javascript|5531358|在此示例中，pointA和pointB都是GeoPoint类的实例。|offset|length|style|BOLD|5531359|entityMap^0|0|0|0|6|6|D|6|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]|$K|W|L|X|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

As stated above, the Location Class is the way to go. Here is the code I have used :

<pre><code>Location locationA = new Location("point A"); 

locationA.setLatitude(pointA.getLatitudeE6() / 1E6); 
locationA.setLongitude(pointB.getLongitudeE6() / 1E6); 

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

locationB.setLatitude(pointB.getLatitudeE6() / 1E6); 
locationB.setLongitude(pointB.getLongitudeE6() / 1E6); 

double distance = locationA.distanceTo(locationB);
</code></pre>

In this example, both pointA and pointB are instances of the GeoPoint class.

From MotoDev snippets (Distance between GPS Coordinates):

originLocation.setLatitude(originLatitude);

Use this code. you will get distance between two geo points.

<pre><code> private String distance(double lati, double longi, double curlati1,
 double curlongi1) {

 double theta = longi - curlongi1;
 double dist = Math.sin(deg2rad(lati)) * Math.sin(deg2rad(curlati1))
 + Math.cos(deg2rad(lati)) * Math.cos(deg2rad(curlati1))
 * Math.cos(deg2rad(theta));
 dist = Math.acos(dist);
 dist = rad2deg(dist);
 dist = dist * 60 * 1.1515;

 dist = dist * 1.609344;

 result = Double.toString(dist);
 System.out.println("dist_result :" + result);
 return (result);
}

/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
/* :: This function converts decimal degrees to radians : */
/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
private double deg2rad(double deg) {
 return (deg * Math.PI / 180.0);
}

/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
/* :: This function converts radians to decimal degrees : */
/* ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: */
private double rad2deg(double rad) {
 return (rad * 180.0 / Math.PI);
}
</code></pre>

I'm working on an Android app and I want to add store locator details and map view.I searched a lot.,but I'm n't getting anything purposeful.I'm tensed and strongly need your help.

The problem is,I want to find the distance between 2 co-ordinates,I got one Haversine formula.,but don't know how to run the program successfully.,As I'm a beginner in Android,please help to do the coding in stepwise.,ie the xml code also..,please.,please.,
