zoom over specific route google map

Question

I have a list of random latitude and longitude points and I am drawing a route between them. My question is how to bound this route within google map I made below utili

Answer 1

This is very late to answer try with this shortest way

First of All get your current location latlongs then your write code for your destination lat longs then calculate distance between your current location and destination location with this code

private double distance(double lat1, double lon1, double lat2, double lon2) {
  double theta = lon1 - lon2;
  double dist = Math.sin(deg2rad(lat1)) * Math.sin(deg2rad(lat2)) + Math.cos(deg2rad(lat1)) * Math.cos(deg2rad(lat2)) * Math.cos(deg2rad(theta));
  dist = Math.acos(dist);
  dist = rad2deg(dist);
  dist = dist * 60 * 1.1515;
   return (dist);
}
private double deg2rad(double deg) {
  return (deg * Math.PI / 180.0);
}
private double rad2deg(double rad) {
  return (rad * 180.0 / Math.PI);
}

• you can never get same lat longs data because of GPS count 95 meters from your current location to display current location pin or lat long data. either you are same location you can never find exact lat long data this must be differ in points so thats by you need to get distance your current location to your fix lat long data points.

• when ever you find "distance" from your destination points to current lat long then fire this code to animate camera and zoom.

  map.moveCamera( CameraUpdateFactory.newLatLngZoom(new LatLng(xxxx,xxxx),21));
