Android定位地图导航——基于百度地图移动获取位置和自动定位

使用百度地图实现如图所示应用，首先自动定位当前我起始位置（小圆点位置），并跟随移动不断自动定位我的当前位置

百度Api不同版本使用会有些差异，本例中加入lib如下：

public class MyApplication extends Application {  static MyApplication myApplication;  BMapManager mBMapManager = null;  String mStrKey = "7ZfuRcOx1G3oZ8TKuTNGm4sO";  boolean m_bKeyRight = true; // 授权Key正确，验证通过  private List<Activity> activityList = new LinkedList<Activity>();  @Override  public void onCreate() {    myApplication = this;    initEngineManager(this);    super.onCreate();  }  public void initEngineManager(Context context) {    if (mBMapManager == null) {      mBMapManager = new BMapManager(context);      Toast.makeText(MyApplication.getInstance().getApplicationContext(),          "BMapManager 初始化SUCSUC!", Toast.LENGTH_LONG).show();    }    if (!mBMapManager.init(mStrKey, new MyGeneralListener())) {      Toast.makeText(MyApplication.getInstance().getApplicationContext(),          "BMapManager 初始化错误!", Toast.LENGTH_LONG).show();    }  }  public static MyApplication getInstance() {    if (myApplication == null) {      myApplication = new MyApplication();    }    return myApplication;  }  public void addActivity(Activity activity) {    activityList.add(activity);  }  public void exit() {    for (Activity activity : activityList) {      activity.finish();    }    System.exit(0);  }  // 常用事件监听，用来处理通常的网络错误，授权验证错误等  static class MyGeneralListener implements MKGeneralListener {    public void onGetNetworkState(int iError) {      if (iError == MKEvent.ERROR.NETWORK_CONNECT) {        Toast.makeText(            MyApplication.getInstance().getApplicationContext(),            "您的网络出错啦！", Toast.LENGTH_LONG).show();      } else if (iError == MKEvent.ERROR_NETWORK_DATA) {        Toast.makeText(            MyApplication.getInstance().getApplicationContext(),            "输入正确的检索条件！", Toast.LENGTH_LONG).show();      }      // ...    }    public void onGetPermissionState(int iError) {      if (iError == MKEvent.ERROR_PERMISSION_DENIED) {        // 授权Key错误：        Toast.makeText(            MyApplication.getInstance().getApplicationContext(),            "请输入正确的授权Key！",            Toast.LENGTH_LONG).show();        MyApplication.getInstance().m_bKeyRight = false;      }    }  }}
