Android使用百度LBS SDK（二）实现定位

标签：android   百度地图   lbs   sdk   定位   

昨天初步接触了百度的LBS SDK，让应用可以通过MapView显示地图，今天在昨天的代码基础上，实现一下定位功能：

首先看一下效果图吧：

左下角的按钮可以切换模式，分为三种：

普通（LocationMode.NORMAL）、

跟随（LocationMode.FOLLOWING）、

罗盘（LocationMode.COMPASS），相信用过百度地图的同学对这几个模式不陌生吧。

下面是代码：

分别声明一个MapView和BaiduMap：

	private MapView mMapView;
	private BaiduMap mBaiduMap;

SDKInitializer.initialize(getApplicationContext());

mCurrentMarker = BitmapDescriptorFactory.fromResource(R.drawable.icon_geo); // 自定义图标
// mCurrentMarker =null ; // 默认图标
mBaiduMap.setMyLocationConfigeration(new MyLocationConfiguration(mCurrentMode, true, mCurrentMarker));

private LocationMode mCurrentMode;

mCurrentMode = LocationMode.NORMAL; // 普通模式
// mCurrentMode = LocationMode.FOLLOWING; // 跟随模式
// mCurrentMode = LocationMode.COMPASS; // 罗盘模式
mBaiduMap.setMyLocationConfigeration(new MyLocationConfiguration(mCurrentMode, true, mCurrentMarker));

初始化：

// 地图初始化
		mMapView = (MapView) findViewById(R.id.bmapView);
		mBaiduMap = mMapView.getMap();
		// 开启定位图层
		mBaiduMap.setMyLocationEnabled(true);
		// 定位初始化
		mLocClient = new LocationClient(this);
		mLocClient.registerLocationListener(myListener);
		LocationClientOption option = new LocationClientOption();
		option.setOpenGps(true);// 打开gps
		option.setCoorType("bd09ll"); // 设置坐标类型
		option.setScanSpan(5000);
		mLocClient.setLocOption(option);
		mLocClient.start();

bd09ll 百度加密经纬度坐标

bd09 百度加密墨卡托坐标

gcj02 国测局加密经纬度坐标

定位SDK监听函数：

public class MyLocationListenner implements BDLocationListener {

		@Override
		public void onReceiveLocation(BDLocation location) {
			// map view 销毁后不在处理新接收的位置
			if (location == null || mMapView == null)
				return;
			MyLocationData locData = new MyLocationData.Builder()
					.accuracy(location.getRadius())
					// 此处设置开发者获取到的方向信息，顺时针0-360
					.direction(100).latitude(location.getLatitude())
					.longitude(location.getLongitude()).build();
			mBaiduMap.setMyLocationData(locData);
			if (isFirstLoc) {
				isFirstLoc = false;
				LatLng ll = new LatLng(location.getLatitude(),
						location.getLongitude());
				MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(ll);
				mBaiduMap.animateMapStatus(u);
			}
		}

		public void onReceivePoi(BDLocation poiLocation) {
		}
	}

@Override
	protected void onPause() {
		mMapView.onPause();
		super.onPause();
	}

	@Override
	protected void onResume() {
		mMapView.onResume();
		super.onResume();
	}

	@Override
	protected void onDestroy() {
		// 退出时销毁定位
		mLocClient.stop();
		// 关闭定位图层
		mBaiduMap.setMyLocationEnabled(false);
		mMapView.onDestroy();
		mMapView = null;
		super.onDestroy();
	}
