百度地图系列04——自定义Marker

本文主要写的是android百度地图开发时自定义marker.上一章百度地图系列03——简单地图定位
1、首先导入BaiduLBS_Android.jar包，还有与之相关的so包，可在百度api上下载。
activity_mylocation.xml代码如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.baidu.mapapi.map.MapView
 android:id="@+id/mylocate_mv" 
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
 />

</LinearLayout>

2、MainActivity代码部分：

public class MainActivity extends Activity {
private BaiduMap mBaiduMap;
private MapView mapView;
//定位客户端
private LocationClient mLocationClient;
//定位监听器
private MyLocationListener myLocationListener;
//定位模式
private LocationMode mLocationMode = LocationMode.NORMAL;
//是否是第一次定位
private volatile boolean isFirstLocation = true;
//最新一次经纬度
private double mCurrentLantitude;
private double mCurrentLongitude;

//当前精度
private float mCurrentAccracy;
//方向传感器的监听器
private MyOrientationListener myOrientationListener;
/**
 * 方向传感器X方向的值
 */
private int mXDirection;
/**
 * 地图定位的模式
 */
// 初始化全局 bitmap 信息，不用时及时 recycle
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
        SDKInitializer.initialize(getApplicationContext());
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_mylocation);

// 第一次定位
        isFirstLocation = true;

        mapView = (MapView) findViewById(R.id.mylocate_mv);
        mBaiduMap = mapView.getMap();
        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
        MapStatusUpdate msu = MapStatusUpdateFactory.zoomTo(15.0f);
        mBaiduMap.setMapStatus(msu);

//初始化定位
        initMyLocation();
// 初始化传感器
        initOritationListener();
    }
/**
 * 初始化方向传感器
 */
public void initOritationListener()
    {
        myOrientationListener = new MyOrientationListener(
                getApplicationContext());
        myOrientationListener
                .setOnOrientationListener(new OnOrientationListener()
                {
@Override
public void onOrientationChanged(float x)
                    {
                        mXDirection = (int) x;
// 构造定位数据
                        MyLocationData locData = new MyLocationData.Builder()
                                .accuracy(mCurrentAccracy)
// 此处设置开发者获取到的方向信息，顺时针0-360
                                .direction(mXDirection)
                                .latitude(mCurrentLantitude)
                                .longitude(mCurrentLongitude).build();
// 设置定位数据
                        mBaiduMap.setMyLocationData(locData);
// 设置自定义图标
                        BitmapDescriptor mCurrentMarker = BitmapDescriptorFactory
                                .fromResource(R.drawable.navi_map_gps_locked);
                        MyLocationConfiguration config = new MyLocationConfiguration(
                                mLocationMode, true, mCurrentMarker);
                        mBaiduMap.setMyLocationConfigeration(config);

                    }
                });
    }
public void initMyLocation()
    {
// 定位初始化
        mLocationClient = new LocationClient(this);
        myLocationListener = new MyLocationListener();
        mLocationClient.registerLocationListener(myLocationListener);
// 设置定位的相关配置
        LocationClientOption option = new LocationClientOption();
        option.setOpenGps(true);// 打开gps
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(1000);
        mLocationClient.setLocOption(option);
    }

public class MyLocationListener 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 || mapView == null)
return;
// 构造定位数据
            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(mXDirection).latitude(location.getLatitude())
                    .longitude(location.getLongitude()).build();
            mCurrentAccracy = location.getRadius();

            BitmapDescriptor mCurrentMarker = BitmapDescriptorFactory
                    .fromResource(R.drawable.navi_map_gps_locked);
            MyLocationConfiguration config = new MyLocationConfiguration(
                    mLocationMode, true, mCurrentMarker);
            mBaiduMap.setMyLocationConfigeration(config);
// 第一次定位时，将地图位置移动到当前位置
if (isFirstLocation)
            {
                isFirstLocation = false;
                LatLng ll = new LatLng(location.getLatitude(),
                        location.getLongitude());
                MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(ll);
                mBaiduMap.animateMapStatus(u);
            }
        }

    }
@Override
protected void onStart()
    {
// 开启图层定位
        mBaiduMap.setMyLocationEnabled(true);
if (!mLocationClient.isStarted())
        {
