本文介绍了如何使用百度地图定位SDK进行位置获取。通过创建LocationClient对象并注册自定义的MyLocationListener监听器来实现定位功能。文中详细展示了如何设置定位参数、启动及停止定位服务，并提供了关键代码示例。

1. 定义对象

LocationClient mLocationClient = null;
 BDLocationListener myListener = new MyLocationListener();
 LocationData locData = null;

2. 新建MyLocationListener类实现BDLocationListener接口

public class MyLocationListener implements BDLocationListener {
        @Override
        public void onReceiveLocation(BDLocation location) {
            if (location == null)
                return;
            mLocationClient.stop();
StringBuffer sb = new StringBuffer(256);
            sb.append("time : ");
            sb.append(location.getTime());
            sb.append("\nerror code : ");
            sb.append(location.getLocType());
            sb.append("\nlatitude : ");
            sb.append(location.getLatitude());
            sb.append("\nlontitude : ");
            sb.append(location.getLongitude());
            sb.append("\nradius : ");
            sb.append(location.getRadius());
            sb.append("\nlocation.getAltitude():" + location.getAltitude());
            if (location.getLocType() == BDLocation.TypeGpsLocation) {
                sb.append("\nspeed : ");
                sb.append(location.getSpeed());
                sb.append("\nsatellite : ");
                sb.append(location.getSatelliteNumber());
            } else if (location.getLocType() == BDLocation.TypeNetWorkLocation) {
                sb.append("\naddr : ");
                sb.append(location.getAddrStr());
            }

            System.out.println(sb.toString());
        }

        public void onReceivePoi(BDLocation poiLocation) {
            // 将在下个版本中去除poi功能
        }
    }

public void MyLocation() {
        mLocationClient = new LocationClient(this.getApplicationContext());
        locData = new LocationData();
        mLocationClient.registerLocationListener(myListener);
        LocationClientOption option = new LocationClientOption();
        option.setOpenGps(true);// 打开gps
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(1000);// 设置发起定位间隔时间

        mLocationClient.setLocOption(option);
        mLocationClient.start();
        if (mLocationClient != null && mLocationClient.isStarted()) {
            mLocationClient.requestLocation();
        } else
            Log.d("LocSDK3", "locClient is null or not started");
    }
