安卓开发-百度地图-利用LocationClient定位到当前位置

LocationClient mBdLocationManager = new LocationClient(getApplicationContext());

LocationClientOption lcOption = new LocationClientOption();

//设置定位模式：高精度，低功耗，仅设备
lcOption.setLocationMode(LocationMode.Hight_Accuracy);
//设置坐标系
lcOption.setCoorType("bd09ll");
//设置GPS打开
lcOption.setOpenGps(true);
//设置需要地址信息
lcOption.setIsNeedAddress(true);
//设置每秒更新一次位置信息
lcOption.setScanSpan(1000);
//设置需要位置描述信息
lcOption.setIsNeedLocationDescribe(true);

mBdLocationManager.setLocOption(lcOption);

mBdLocationManager.registerLocationListener(mBdLocationListener);

private BDAbstractLocationListener mBdLocationListener = new BDAbstractLocationListener() {
//当位置对象为空或者因为退出而到时地图对象销毁为空时，不监听
public void onReceiveLocation(BDLocation location) {
if (location == null || mMapView == null)
return;

Log.v("aaa","方向：" + location.getDirection() + ",纬度：" + location.getLatitude()
+ "，经度：" + location.getLongitude()
+ ",时间：" + location.getTime() + ",描述："
+ location.getLocationDescribe() + ",地址：" + location.getAddrStr() + ",精度：" + location.getRadius());
}
};

mBdLocationManager.start();

5.1：地图对象开启定位图层：

mBaiduMap.setMyLocationEnabled(true);

5.2：地图对象设置定位时的地图缩放级别（500米）：

mBaiduMap.setMapStatus(MapStatusUpdateFactory.zoomTo(15.0f));

5.3：为地图对象设置定位数据：精度，方向，经度，纬度

MyLocationData locData = new MyLocationData.Builder()
.accuracy(location.getRadius())
.latitude(location.getLatitude())
.longitude(location.getLongitude())
.direction(100)
.build();

mBaiduMap.setMyLocationData(locData);

5.4：为地图对象配置参数：定位方式（罗盘态，跟随态，常态），是否允许显示方向，用户自定义显示图标：

MyLocationConfiguration myLocConfig = new MyLocationConfiguration(locationMode, true, mLocBitmap);

mBaiduMap.setMyLocationConfiguration(myLocConfig);
