public class App extends Application {static App mDemoApp;//百度MapAPI的管理类public BMapManager mBMapMan = null;// 授权Key// 申请地址:http://dev.baidu.com/wiki/static/imap/key/public String mStrKey = "Your APPKey";boolean m_bKeyRight = true; // 授权Key正确,验证通过// 常用事件监听,用来处理通常的网络错误,授权验证错误等public static class MyGeneralListener implements MKGeneralListener {@Overridepublic void onGetNetworkState(int iError) {Log.d("MyGeneralListener", "onGetNetworkState error is "+ iError);Toast.makeText(App.mDemoApp.getApplicationContext(), "您的网络出错啦!",Toast.LENGTH_LONG).show();}@Overridepublic void onGetPermissionState(int iError) {Log.d("MyGeneralListener", "onGetPermissionState error is "+ iError);if (iError == MKEvent.ERROR_PERMISSION_DENIED) {// 授权Key错误:Toast.makeText(App.mDemoApp.getApplicationContext(), "文件输入正确的授权Key!",Toast.LENGTH_LONG).show();App.mDemoApp.m_bKeyRight = false;}}}@Overridepublic void onCreate() {Log.v("BMapApiDemoApp", "onCreate");mDemoApp = this;mBMapMan = new BMapManager(this);mBMapMan.init(this.mStrKey, new MyGeneralListener());mBMapMan.getLocationManager().setNotifyInternal(10, 5);super.onCreate();}@Override//app的退出之前调用mapadpi的destroy()函数,避免重复初始化带来的时间消耗public void onTerminate() {if (mBMapMan != null) {mBMapMan.destroy();mBMapMan = null;}super.onTerminate();}} 

三、编写公交的路线图层(CustomRouteOverLay)和图标标识(CustomOverlayItem)XJQHTML5中文学习网 - HTML5先行者学习网

主要公交、步行和驾车线路图层,将公交、步行和驾车出行方案的路线及关键点显示在地图上,根据车辆路线的起点和终点进行驾车路线的检索;XJQHTML5中文学习网 - HTML5先行者学习网

CustomOverlayItem扩展ItemizedOverlayXJQHTML5中文学习网 - HTML5先行者学习网

覆盖物的集合类,使用这个类可以将地图上具有相同属性或者特性的坐标使用图标标识出来,OverLayItem 这个类对象则是ItemizedOverLay中一个一个的Item对象 也就是每个坐标对应的覆盖物XJQHTML5中文学习网 - HTML5先行者学习网

public class CustomOverlayItem extends ItemizedOverlay {// private List GeoList = new ArrayList();private Context mContext;private OverlayItem overlay;boolean showtext;// private String title;private Drawable marker;public CustomOverlayItem(Drawable marker, Context context, GeoPoint p,String title,String sinppet, boolean showtext) {super(boundCenterBottom(marker));this.mContext = context;// 用给定的经纬度构造GeoPoint,单位是微度 (度 * 1E6)// point = p;this.showtext = showtext;// this.title = title;this.marker = marker;overlay = new OverlayItem(p, title, sinppet);populate(); // createItem(int)方法构造item。一旦有了数据,在调用其它方法前,首先调用这个方法}@Overrideprotected OverlayItem createItem(int i) {return overlay;}@Overridepublic int size() {return 1;}@Overridepublic void draw(Canvas canvas, MapView mapView, boolean arg2) {// TODO Auto-generated method stubsuper.draw(canvas, mapView, arg2);// Projection接口用于屏幕像素坐标和经纬度坐标之间的变换Projection projection = mapView.getProjection();String title = overlay.getTitle();// 把经纬度变换到相对于MapView左上角的屏幕像素坐标Point point = projection.toPixels(overlay.getPoint(), null);// 可在此处添加您的绘制代码Paint paintText = new Paint();Paint paint = new Paint();paint.setAlpha(255);paint.setColor(Color.DKGRAY);paint.setStrokeWidth(5);paintText.setColor(Color.BLUE);paintText.setTextSize(15);// canvas.drawCircle(point.x, point.y, 100, paint);canvas.drawText(title, point.x-30, point.y-50, paintText); // 绘制文本// 调整一个drawable边界,使得(0,0)是这个drawable底部最后一行中心的一个像素boundCenterBottom(marker);}@Override// 处理当点击事件protected boolean onTap(int i) {if (showtext)Toast.makeText(this.mContext, overlay.getTitle(), Toast.LENGTH_SHORT).show();return true;}}
