How to calculate distance from different markers in a map and then pick up the least one

Question

I have to get distance from different markers on the map to the current location of the device and the pick up the shortest one. I have the lat and long for the markers and

Answer 1

How about looping over all markers and checking the distance using Location.distanceBetween? There is no magic involved ;)

List markers;
LatLng currentPosition;

float minDistance = Float.MAX_VALUE;
Marker closest = null;
float[] currentDistance = new float[1];
for (Marker marker : markers) {
    LatLng markerPosition = marker.getPosition();
    Location.distanceBetween(currentPosition.latitude, currentPosition.longitude, markerPosition.latitude, markerPosition.longitude, currentDistance);
    if (minDistance > currentDistance[0]) {
        minDistance = currentDistance[0];
        closest = marker;
    }
}
