android获取位置和计算两个位置坐标

这里参照不同的信息

private void ShowLoction(Location ln){
view.setText("纬度:" + ln.getLatitude() + ",经度:" + ln.getLongitude() + "=>" + kk);
}

// 最后的返回值单位为英里,1英里=1.609344公里 =0.8684海里

public double getDistance(double lat1, double lon1, double lat2, double lon2) {
float[] results=new float[1];
Location.distanceBetween(lat1, lon1, lat2, lon2, results);
return results[0];
}

public Location getLocation() {
final LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Location ln = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (ln == null)
ln = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
return ln;
}
