Mit GPS erhalten Sie die Distanz, die eine Person gegangen ist (2)

Als erstes. Dies ist eher eine Frage zu einem Problem und dann erhalten Sie eine Antwort. Leute auf diesem Board werden nicht für dich arbeiten.

Jetzt zu einem Weg, um zu erreichen, was Sie wollen.

Sie müssen einen Dienst verwenden, um den Benutzer und die Standorte im Auge zu behalten. Der einfache Weg wäre, den mytracks-Dienst, der als Addon für Ihre Anwendung zur Verfügung steht, einzubinden oder den Code von mytracks zu verwenden, um einen eigenen Tracking-Service zu erstellen. http://code.google.com/p/mytracks/

Sie können es sich ansehen: http://code.google.com/p/mytracks/w/list

Jungs Ich bin in der Lage, den aktuellen Standort Längengrad und Breite mit dem untenstehenden Code zu erhalten. Ich habe zwei Knöpfe Start walking and Stop Walking.

Wenn Sie auf Start Walking gehen, erhalten Sie den aktuellen Standort (Längen- und Breitengrad). Die Person beginnt von A (Quelle) aus zu laufen und geht von einer bestimmten Zeit zurück zu A (jetzt wird sie Ziel). Danach klickt sie auf Stop Taste.

Jetzt muss ich dem Benutzer diese Details zeigen:

1.Entfernung, die er in Kms ging.

2.Time nahm er in Minuten.

(optional) 3. Geschwindigkeit oder Durchschnittsgeschwindigkeit.

    }

Wie man das erreicht.

Funktion zur Berechnung der Entfernung ...

public double getDistance(double lat1, double lon1, double lat2, double lon2) {
    double latA = Math.toRadians(lat1);
    double lonA = Math.toRadians(lon1);
    double latB = Math.toRadians(lat2);
    double lonB = Math.toRadians(lon2);
    double cosAng = (Math.cos(latA) * Math.cos(latB) * Math.cos(lonB-lonA)) +
                    (Math.sin(latA) * Math.sin(latB));
    double ang = Math.acos(cosAng);
    double dist = ang *6371;
    return dist;
}
