手机获取经纬度怎么做？

[bluejoy345]

谁能给点头绪？
网上找到这段代码

        try {
            Criteria criteria = new Criteria();
            criteria.setSpeedAndCourseRequired(true);
            LocationProvider lp = LocationProvider.getInstance(criteria);
            if (lp != null) { 
                Location l = lp.getLocation(300);
                if (l.isValid()) {
                    Coordinates c = l.getQualifiedCoordinates();
                    if (c!=null) {
                        course = l.getCourse(); // moving direction is degrees
                        speed = l.getSpeed() * 3.6f; // m/s converted to km/h
                        double latitude = c.getLatitude();
                        double longitude = c.getLongitude();
                        latitudeString = "Latitude: " + latitude;
                        longitudeString = "Longitude: " + longitude;
                        courseString = "Course: " + course + '°';
                        speedString = "Speed: " + speed;
                        if (speedString.length() > 12) speedString = speedString.substring(0, 12);
                        speedString += "km/h";
 
                    }
                }
                else {
        	    System.out.println("Location is not valid!");
                }
            }
            else {
                System.out.println("LocationProvider = null!");
            }
        } catch (LocationException le) { // not able to retrieve location information
            System.out.println("LocationException: " + le.getMessage());
        } catch (InterruptedException ie) { 
            System.out.println("InterruptedException: " + ie.getMessage());
        }        

但是看不太懂，放到手机里面也没什么反应，我的手机是支持google手机地图获取当前位置的。

这个要找小贱贱！他在正在写类似的程序！

看看jsr179是怎么说的

[pi88dian88]

JSR179 Location API for J2ME

http://www.j2medev.com/api/location/

对着api看下，应该能懂的

路过拿点分！

1。 GPS 精确定位。也就是楼上各位说的jsr179规范。
2。基站模糊定位。有移动提供的服务，也有通过google的不公开的api提供的服务。

coordinates.getAltitude(); //海拔
coordinates.getLatitude(); //纬度
coordinates.getLongitude(); //经度
location.getTimestamp(); //时间戳
location.getSpeed(); //速度
location.getCourse(); //方向
