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();            // 设置定位数据            mBaiduMap.setMyLocationData(locData);            mCurrentLantitude = location.getLatitude();            mCurrentLongitude = location.getLongitude();            // 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);            // 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);
