使用百度地图，定位你当前位置并显示

1、准备

• 注册百度开发者账号
• 到百度地图开放平台创建应用（as获取SHA1值）
  

2、将sdk整到你的项目中去

- 在你app的gradle.build中添加

 dependencies {......
compile files('libs/baidumapapi_base_v4_0_0.jar')
compile files('libs/baidumapapi_cloud_v4_0_0.jar')
compile files('libs/baidumapapi_map_v4_0_0.jar')
compile files('libs/baidumapapi_radar_v4_0_0.jar')
compile files('libs/baidumapapi_search_v4_0_0.jar')
compile files('libs/baidumapapi_util_v4_0_0.jar')
compile files('libs/locSDK_6.13.jar')
}android {......sourceSets {main {jniLibs.srcDir 'libs'}}}

3、在AndroidManifest.xml中配置

<!--baiduMap-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS" />

 <meta-dataandroid:name="com.baidu.lbsapi.API_KEY"android:value="百度key" />

<!--百度地图定位监听服务--><serviceandroid:name="com.baidu.location.f"android:enabled="true"android:process=":remote" ></service>

4、在activity中

1. oncreate中

   地图初始化

   mBaiduMap = mMapView.getMap();
   // 开启定位图层
   mBaiduMap.setMyLocationEnabled(true);
   // 定位初始化
   mLocClient = new LocationClient(getActivity());
   mLocClient.registerLocationListener(myListener);
   LocationClientOption option = new LocationClientOption();
   option.setOpenGps(true); // 打开gps
   option.setCoorType("bd09ll"); // 设置坐标类型
   option.setScanSpan(1000);
   mLocClient.setLocOption(option);
   mLocClient.start();
   LatLng ll = new LatLng(100,100);
   MapStatus.Builder builder = new MapStatus.Builder();
   builder.target(ll).zoom(18.0f);
   mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));
   

2. 内部类监听
   public class MyLocationListenner 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 || mMapView == null) {return;}mBaiduMap.clear();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(100).latitude(location.getLatitude()).longitude(location.getLongitude()).build();mBaiduMap.setMyLocationData(locData);LatLng llA=new LatLng(location.getLatitude(),location.getLongitude());MarkerOptions ooA = new MarkerOptions().position(llA).icon(bdA).zIndex(9).draggable(true);mBaiduMap.addOverlay(ooA);if (isFirstLoc) {isFirstLoc = false;LatLng ll = new LatLng(location.getLatitude(),location.getLongitude());MapStatus.Builder builder = new MapStatus.Builder();builder.target(ll).zoom(18.0f);mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build()));}
   }public void onReceivePoi(BDLocation poiLocation) {
   }
   

   }

5、在布局文件中

 <com.baidu.mapapi.map.MapViewandroid:id="@+id/map_view"android:layout_width="match_parent"android:layout_height="match_parent"/>

6、到此应该可以显示地图了，手机开wifi,开gsp试一试吧！
