How to Pull String Result In To Another Class

Question

I've been looking at the right way to work with the following code which is in my MainActivity and pull the result in to another activity so I can call a URL of 'http://www.website.com?lat:lng:speed:bearing' which will be based on the values pulled through.

locationCheck() sits in my Mainactivity how ever I have a JSONParse activity which I want to use the location found to construct the url. What I do not is how to share the result.

In HTML or PHP I would use a global value.

Although I can call and toast on create I have not found the best way to share the result.

public void locationCheck() {
        MyLocation myLocation = new MyLocation();       
        // this is the result
        myLocation.getLocation(this, locationResult);
    }

    public LocationResult locationResult = new LocationResult() {
        public void gotLocation(final Location location) {
            try {
                double lat = location.getLatitude();
                double lng = location.getLongitude();
                if (lat != 0.0 && lng != 0.0) {

                    String sLat;
                    String sLng;
                    sLat = Double.toString(lat);
                    sLng = Double.toString(lng);
                    String gps_location = sLat + " : " + sLng;
                    Toast.makeText(getBaseContext(),
                            "We got gps location! " + gps_location + "",
                            Toast.LENGTH_LONG).show();
                }
            } catch (Exception e) {

            }
        }
    };

Sorry - where I wrote class I did mean activity.... reworded. — Terran Brown, May 12 '13 at 14:48

Thanks.... for any one following I'm also going to look at http://stackoverflow.com/questions/4878159/android-whats-the-best-way-to-share-data-between-activities & http://stackoverflow.com/questions/3100726/sharing-global-variables-across-activities-problem-when-using-a-webview ( Intents ) — Terran Brown, May 12 '13 at 19:42

The following allows me to have a location activity run and post its results as strings in to a globally accessible form which then allows me to use in the format of creating a context aware URL through another activity...

As you can see the toast uses the global value which allowed me to test they where accessible.

In the Mainactivity....

public void locationCheck() {
    MyLocation myLocation = new MyLocation();       
    // this is the result
    myLocation.getLocation(this, locationResult);
}

public LocationResult locationResult = new LocationResult() {
    public void gotLocation(final Location location) {
        try {
            double lat = location.getLatitude();
            double lng = location.getLongitude();
            double bearing = location.getBearing();
            double speed = location.getSpeed();
            if (lat != 0.0 && lng != 0.0) {

                String sLat;
                String sLng;
                String sBearing;
                String sSpeed;  

                sLat = Double.toString(lat);
                sLng = Double.toString(lng);
                sBearing = Double.toString(bearing);
                sSpeed = Double.toString(speed);

                // send to global vars

                Globals.glat = sLat;
                Globals.glng = sLng;
                Globals.gBearing = sBearing;
                Globals.gSpeed = sSpeed;    

                String gps_location = Globals.glat + " : " + Globals.glng;

                @SuppressWarnings("unused")
                String gps_location2 = sBearing + " : " + sSpeed;

                Toast.makeText(getBaseContext(),
                        "We got gps location! " + gps_location + "",
                        Toast.LENGTH_LONG).show();
            }
        } catch (Exception e) {

        }
    }
};

In the Globals Activity

// Global Values

// http://stackoverflow.com/questions/708012/android-how-to-declare-global-variables?rq=1

   public class Globals {

   static String glat; 
   static String glng;
   static String gBearing;
   static String gSpeed;

}
