      &nbsp;&nbsp;百度地图移动版API（Android）是一套基于Android设备的应用程序接口，通过该接口，可以轻松访问 
     <strong>百度服务和数据</strong>，构建功能丰富、交互性强的 
     <strong>地图应用程序</strong>。&nbsp; &nbsp; &nbsp; &nbsp; 
    </div> 
    <div>

    </div> 
    <div>
      &nbsp;百度地图移动版API不仅包含构建地图的基本接口，还提供了本地 
     <strong>搜索</strong>、 
     <strong>路线规划</strong>、 
     <strong>地图定位</strong>等数据服务。

    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onGetPermissionState(int iError) { 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (iError == MKEvent.ERROR_PERMISSION_DENIED) { 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Toast.makeText(getApplicationContext(), "授权失败", 1).show(); 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }

    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onGetNetworkState(int iError) { 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (iError == MKEvent.ERROR_NETWORK_CONNECT) { 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Toast.makeText(getApplicationContext(), "网络连接失败", 1).show(); 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; }); 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      &nbsp; &nbsp; } 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <strong>6、引入布局（地图控件）common.xml</strong> 
    </div> 
    <div>
      Layout中添加MapView控件用于展示地图 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    </div> 
    <div>
      &nbsp; &nbsp; xmlns:tools="http://schemas.android.com/tools" 
    </div> 
    <div>
      &nbsp; &nbsp; android:layout_width="match_parent" 
    </div> 
    <div>
      &nbsp; &nbsp; android:layout_height="match_parent" 
    </div> 
    <div>
      &nbsp; &nbsp; &gt; 
    </div> 
    <div>
      &nbsp; &nbsp; &lt;com.baidu.mapapi.map. 
     <strong>MapView</strong> 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="wrap_content" 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content" 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;/&gt; 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      &lt;/RelativeLayout&gt; 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      运行演示，看看显示效果。 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      7、缩放级别 
    </div> 
    <div>
      打开浏览器看一看百度地图最小级别 
    </div> 
    <div>
      地图缩放级别 
    </div> 
    <div>
      V1.X : 3--18级别 
    </div> 
    <div>
      V2.X : 3--19级别 
    </div> 
    <div>
      V2.X和V1.X的主要区别 
    </div> 
    <div>
      A:修改了地图文件袋格式，节省空间。 
    </div> 
    <div>
      例如北京市地图：V1.x：120MB，V2.X：20MB,相对于压缩9倍。 
    </div> 
    <div>
      B:放大级别多了一个级别变成19级别，增加了3D效果。 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      8、MapController地图控制器 
    </div> 
    <div>
      创建管理工具，并初使化 
    </div> 
    <div>
      BMapManager在init时校验key(300)和网络状态(2)，关于状态码信息我们可以在MKEvent查询 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      管理某个具体的MapView:缩放、旋转、移动； 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      private void init() { 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; //MapController管理某个MapView:缩放、旋转、移动 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; mapView = (MapView) findViewById(R.id.map_view); 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; 
     <strong>controller = mapView.getController();</strong> 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; //设置地图的缩放级别，这个参数取值范围3--19 
    </div> 
    <div>
      &nbsp; &nbsp; &nbsp; &nbsp; 
     <strong>controller.setZoom(12);</strong> 
    </div> 
    <div>
      &nbsp; &nbsp; } 
    </div> 
    <div>
      运行起来，演示一下。 
    </div> 
    <div> 
     <span style="color:rgb(250,122,0)"><strong>9、添加控制地图放大放小按钮</strong></span> 
    </div> 
    <div>
      //需要在mapview添加一组按钮，mapview.addView(view) 
    </div> 
    <div>
      &nbsp; 
     <span style="color:rgb(54,101,238)">&nbsp; <strong>mapView.setBuiltInZoomControls(true);</strong></span> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      10. 
     <span style="color:rgb(45,79,201)"><strong>中心点的设置</strong></span> 
    </div> 
    <div>
      &nbsp;默认地图中心设置是天安门 
    </div> 
    <div>
      &nbsp;如果自己设置喜欢的中心点？ 
    </div> 
    <div>
      北京天安门广场的经纬度(东经:116°23′17〃,北纬:39°54′27〃 ） 
    </div> 
    <div>
      int latitudeE6 = 116°23′17 乘以 10六次方 
    </div> 
    <div>
      这样便于支持小数点后几位 
    </div> 
    <div>
      代码如下： 
    </div> 
    <div>
      int latitude=(int) (40.107218*1E6);//纬度 
    </div> 
    <div>
      int longitude=(int) (116.385178*1E6);//经度 
    </div> 
    <div>

     <h3><strong>地图图层<span style="font-family:Times New Roman">-(20)</span></strong></h3> 
     <p><strong>什么是地图图层</strong></p> 
     <p>地图可以包含一个或多个图层，每个图层在每个级别都是由若干个图块组成的，它们覆盖了地图的整个表面。例如您所看到包括街道、兴趣点、学校、公园等内容的地图展现就是一个图层，另外交通流量的展现也是通过图层来实现的。</p> 
     <p><strong>图层分类</strong></p> 
     <p><strong>底图</strong></p> 
     <p>&nbsp;&nbsp;&nbsp;&nbsp;基本的地图图层，包括若干个缩放级别，显示基本的地图信息，包括道路、街道、学校、 公园等内容。</p> 
     <p><strong>实时交通信息图：<span style="color:rgb(250,122,0)"><span style="font-family:Times New Roman">MapView.setTraffic(true)</span></span></strong></p>

     <h3><strong>覆盖物概念</strong></h3> 
     <p>所有叠加或覆盖到地图的内容，我们统称为<strong>地图覆盖物</strong>。如标注、矢量图形元素<span style="font-family:Times New Roman">(</span><span style="font-family:宋体">包括：折线和多边形和圆</span><span style="font-family:Times New Roman">)</span><span style="font-family:宋体">、定位图标等。覆盖物拥有自己的地理坐标，当您拖动或缩放地图时，它们会相应的处理。</span></p> 
     <p>覆盖物包括：</p> 
     <p>覆盖物的抽象基类：<strong><span style="color:rgb(250,122,0)">Overlay</span><span style="font-family:宋体">（核心类），第四个核心类</span></strong></p> 
     <p>几何图形绘制覆盖物：<span style="font-family:Times New Roman">GraphicsOverlay</span></p> 
     <p>文字绘制覆盖物：<span style="font-family:Times New Roman">TextOverlay</span></p> 
     <p>分条目覆盖物：<span style="font-family:Times New Roman">ItemizedOverlay</span></p> 
     <p>本地搜索覆盖物：<span style="font-family:Times New Roman">PoiOverlay</span></p> 
     <p>路线规划覆盖物：<span style="font-family:Times New Roman">RouteOverlay</span></p>

     <p>Overlay是一个基类，它表示可以显示在地图上方的覆盖物。</p> 
     <p>从2.0.0开始，SDK不支持直接继承Overlay , 用户可通过继承ItemizedOverlay来添加覆盖物。</p> 
     <p>关于Overlay的使用，即在MapView上显示Overlay的步骤</p> 
     <p><strong>1、需要获取到MapView中保存Overlay的集合</strong></p> 
     <p><strong><span style="color:rgb(255,0,0)">2、在其中添加需要显示的内容</span></strong></p> 
     <p><strong>3、然后刷新界面</strong></p> 
     <p>注意：所不同的是如何给不同的Overlay设置数据，这也是重点。</p>

    </div> 
    <div>
      addView(View child, LayoutParams params) 
    </div> 
    <div>
      LayoutParams：MapView.LayoutParams 
    </div> 
    <div>
      MapView.LayoutParams(int width, int height, GeoPoint point, int alignment)，其中alignment为对其方式，采用BOTTOM_CENTER 
    </div> 
    <div>
      在处理onTap时更新Layout，利用LayoutParams传递点位信息，同时可以获取标题信息，设置给TextView 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      添加泡泡代码如下红色部分：

  <tr> 
   <td> 
    <div>
      1、百度地图移动版API集成搜索服务包括 
    </div> 
    <div>
      位置检索、周边检索、范围检索、公交检索、驾乘检索、步行检索。 
    </div> 
    <div>
      2、 
     <strong>核心类： <span style="color:rgb(209,0,255)">MKSearch</span>和<span style="color:rgb(209,0,255)">MKSearchListener</span></strong> 
    </div> 
    <div>
      3、实现思路 
    </div> 
    <div>
      初始化MKSearch类，通过init方法注册搜索结果的监听对象MKSearchListener，实现异步搜索服务。 
    </div> 
    <div>
      通过自定义MySearchListener实现类，处理不同的回调方法，获得搜索结果。 
    </div> 
    <div>
      注意，MKSearchListener只支持一个，以最后一次设置为准 
    </div> 
    <div>
      4、结合覆盖物展示搜索 
    </div> 
    <div> 
     <strong>本地搜索覆盖物：<span style="color:rgb(209,0,255)">PoiOverlay</span>-圆形区域的、矩形区域、全城范围内搜索。</strong>

    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      本地搜索 
    </div> 
    <div>
      1、POI(Point of Interest兴趣点)搜索有三种方式 
    </div> 
    <div>
      根据范围和检索词发起范围检索PoiSearchInbounds 兴趣的界内搜索 
    </div> 
    <div> 
     <strong>周边检索<span style="color:rgb(209,0,255)">poiSearchNearBy</span></strong> 
    </div> 
    <div> 
     <strong>城市poi检索<span style="color:rgb(209,0,255)">poiSearchInCity</span></strong> 
    </div> 
    <div> 
     <strong>poi详细信息检索 <span style="color:rgb(209,0,255)">poiDetailSearch</span></strong>

    <div>
      对于poiSearchInCity，type的值为MKSearch.TYPE_POI_LIST 
    </div> 
    <div> 
     <br> 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      3、查询加油站信息 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      多种查询方法，但结果的处理都在MKSearchListener的onGetPoiResult方法中，在该方法中可以通过传递的type值来区分是范围搜索还是城市检索。 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      处理步骤： 
    </div> 
    <div>
      判断服务器结果返回 
    </div> 
    <div>
      创建poi覆盖物 
    </div> 
    <div>
      将服务器返回数据添加到poi覆盖物中 
    </div> 
    <div>
      添加覆盖物到MapView 
    </div> 
    <div>
      刷新MapView 
    </div> 
    <div> 
     <br> 
    </div> 
    <div>
      4、注意事项 
    </div> 
    <div>
      POI检索结果每页容量默认情况下为10，可以通过setPoiPageCapacity设置，支持1-50(10) 
    </div> 
    <div>
      翻页功能通过MKSearch类的goToPoiPage实现，该方法是异步函数，搜索成功后会调用注册的事件处理函数onGetPoiResult 返回查询页的结果。 
    </div> 
    <div>
      支持分类搜索，例如mSearch.poiSearchInCity("北京", "娱乐") 
    </div> </td>

      <p>在百度地图移动版<span style="font-family:Times New Roman">API</span><span style="font-family:宋体">中，提供一个重要的特色功能：定位，通过这个功能，能获取到用户当前所在位置。</span></p> 
      <p>在程序中，如果使用此功能，必须注册<span style="font-family:Times New Roman">GPS</span><span style="font-family:宋体">和网络的使用权限。</span></p> 
      <p><strong>在获取用户位置时，优先使用<span style="font-family:Times New Roman">GPS</span><span style="font-family:宋体">进行定位；如果</span><span style="font-family:Times New Roman">GPS</span><span style="font-family:宋体">定位没有打开或者没有可用位置信息，则会通过判断网络是否连接（即确认手机是否能上网，不论是连接</span><span style="font-family:Times New Roman">2G/3G</span><span style="font-family:宋体">或</span><span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">网络），如果是，则通过请求百度网络定位服务，返回网络定位结果。为了使获得的网络定位结果更加精确，请打开手机的</span><span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">开关。</span></strong></p> 
      <p>目前系统自带的网络定位服务精度低，且服务不稳定、精度低，并且从未来的趋势看，基站定位是不可控的（移动公司随时可能更改基站编号以垄断定位服务），而<span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">定位则不然，它是一种精度更高、不受管制的定位方法。国内其它使用</span><span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">定位的地图软件，</span><span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">定位基本不可用，百度的定位服务量化指标优秀，网络接口返回速度快（服务端每次定位响应时间</span><span style="font-family:Times New Roman">50</span><span style="font-family:宋体">毫秒以内），平均精度</span><span style="font-family:Times New Roman">70</span><span style="font-family:宋体">米，其中</span><span style="font-family:Times New Roman">Wi-Fi</span><span style="font-family:宋体">精度</span><span style="font-family:Times New Roman">40</span><span style="font-family:宋体">米左右，基站定位精度</span><span style="font-family:Times New Roman">200</span><span style="font-family:宋体">米左右，覆盖率</span><span style="font-family:Times New Roman">98%</span><span style="font-family:宋体">，在国内处于一枝独秀的地位。</span></p>

      <p>两个方法需要实现：</p> 
      <p>1.<span style="font-family:宋体">接收异步返回的定位结果，参数是</span><span style="font-family:Times New Roman">BDLocation</span><span style="font-family:宋体">类型参数。</span></p>
