Android设备的移动速度 [英] Android Device Movement Speed

问题描述

我需要计算在每个位置更新的移动速度。

I need to calculate the movement speed on every location update.

我用下面的code的位置更新。

I'm using the following code for the location update.

public class FlirtLocationListener implements LocationListener
{
    @Override
    public void onLocationChanged(Location location) 
    {

                // My Code on the location update
    }
    @Override
    public void onProviderDisabled(String provider) 
    {
        Log.i("OnProviderDisabled", "OnProviderDisabled");
    }
    @Override
    public void onProviderEnabled(String provider) 
    {

        Log.i("onProviderEnabled", "onProviderEnabled");
    }
    @Override
    public void onStatusChanged(String provider, int status,
            Bundle extras) 
    {
        Log.i("onStatusChanged", "onStatusChanged");
    }
}

如何获得移动速度？我应计算的第一和下一个位置之间的两个更新和距离之间的时间？或者是有一些其他的方式？

How to get the movement speed? Should I calculate the time between the two updates and the distance between first and next location? Or is there some other way?

推荐答案

由于@jsmith表示，目前在位置在 getSpeed​​（）方法的.class 。

As @jsmith said there is a getSpeed() method in the Location.class.

public class LocationListener implements LocationListener
    {
        @Override
        public void onLocationChanged(Location location) 
        {
               float speed = location.getSpeed();
        }
    }
