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

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

6、到此应该可以显示地图了，手机开wifi,开gsp试一试吧！
