1、初始化

SDKInitializer.initialize(getApplicationContext());//我测试在Application的onCreate()不行，必须在activity的onCreate()中

2、配置map参数

[html] view plain copy

private void initMap() {

// 地图初始化

mMapView = (MapView) findViewById(R.id.id_bmapView);

mBaiduMap = mMapView.getMap();

// 开启定位图层

mBaiduMap.setMyLocationEnabled(true);

// 定位初始化

mlocationClient = new LocationClient(this);

mlocationClient.registerLocationListener(myListener);

LocationClientOption option = new LocationClientOption();

option.setOpenGps(true); // 打开gps

option.setCoorType("bd09ll"); // 设置坐标类型

option.setScanSpan(5000);//设置onReceiveLocation()获取位置的频率

option.setIsNeedAddress(true);//如想获得具体位置就需要设置为true

mlocationClient.setLocOption(option);

mlocationClient.start();

mCurrentMode = MyLocationConfiguration.LocationMode.FOLLOWING;

mBaiduMap.setMyLocationConfigeration(new MyLocationConfiguration(

mCurrentMode, true, null));

myOrientationListener = new MyOrientationListener(this);

//通过接口回调来实现实时方向的改变

myOrientationListener.setOnOrientationListener(new MyOrientationListener.OnOrientationListener() {

@Override

public void onOrientationChanged(float x) {

mCurrentX = x;

}

});

myOrientationListener.start();

mSearch = RoutePlanSearch.newInstance();

mSearch.setOnGetRoutePlanResultListener(this);

initMarkerClickEvent();

}

3、获取当前地址

[html] view plain copy

public class MyLocationListenner implements BDLocationListener {

@Override

public void onReceiveLocation(BDLocation bdLocation) {

// map view 销毁后不在处理新接收的位置

if (bdLocation == null || mMapView == null) {

return;

}

MyLocationData locData = new MyLocationData.Builder()

.accuracy(bdLocation.getRadius())

.direction(mCurrentX)//设定图标方向 // 此处设置开发者获取到的方向信息，顺时针0-360

.latitude(bdLocation.getLatitude())

.longitude(bdLocation.getLongitude()).build();

mBaiduMap.setMyLocationData(locData);

currentLatitude = bdLocation.getLatitude();

currentLongitude = bdLocation.getLongitude();

current_addr.setText(bdLocation.getAddrStr());

currentLL = new LatLng(bdLocation.getLatitude(),

bdLocation.getLongitude());

startNodeStr = PlanNode.withLocation(currentLL);

//option.setScanSpan(5000)，每隔5000ms这个方法就会调用一次，而有些我们只想调用一次，所以要判断一下isFirstLoc

if (isFirstLoc) {

isFirstLoc = false;

LatLng ll = new LatLng(bdLocation.getLatitude(),

bdLocation.getLongitude());

MapStatus.Builder builder = new MapStatus.Builder();

//地图缩放比设置为18

builder.target(ll).zoom(18.0f);

mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));

changeLatitude = bdLocation.getLatitude();

changeLongitude = bdLocation.getLongitude();

if (!isServiceLive) {

addOverLayout(currentLatitude, currentLongitude);

}

}

}
