    <!-- 这个权限用于进行网络定位 -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <!-- 这个权限用于访问GPS定位 -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

(2)在Application标签中声明定位的service组件

        <service android:name="com.baidu.location.f"
            android:enabled="true"
            android:process=":remote"/>

3.开启地图的定位图层

mBaiduMap=mapView.getMap();
mBaiduMap.setMyLocationEnabled(true);

4.构造地图数据

继承抽象类BDAbstractListener并重写其onReceieveLocation方法来获取定位数据，并将其传给MapView。

public class MyLocationListener extends BDAbstractLocationListener {
        @Override
        public void onReceiveLocation(BDLocation location) {
            //mapView 销毁后不在处理新接收的位置
            if (location == null || mMapView == null){
                return;
            }
            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(location.getDirection()).latitude(location.getLatitude())
                    .longitude(location.getLongitude()).build();
            mBaiduMap.setMyLocationData(locData);
    }

5.通过LocationClient发起定位

public void init() {
        mBaiduMap.setMyLocationEnabled(true);
        //定位初始化
        LocationClient mLocationClient = new LocationClient(this);
        //通过LocationClientOption设置LocationClient相关参数
        LocationClientOption option = new LocationClientOption();
        option.setOpenGps(true); // 打开gps
        option.setCoorType("BD09LL"); // 设置坐标类型
        option.setScanSpan(1000);
        //设置locationClientOption
        mLocationClient.setLocOption(option);
        //注册LocationListener监听器
        MyLocationListener myLocationListener = new MyLocationListener();
        mLocationClient.registerLocationListener(myLocationListener);
        //开启地图定位图层
        mLocationClient.start();
    }

6.正确管理各部分的生命周期

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mapView=findViewById(R.id.bmapView);
        mBaiduMap=mapView.getMap();
        init();
    }
    @Override
    protected void onResume() {
        mapView.onResume();
        super.onResume();
    }
    @Override
    protected void onPause() {
        mapView.onPause();
        super.onPause();
    }
    @Override
    protected void onDestroy() {
        mBaiduMap.setMyLocationEnabled(false);
        mapView.onDestroy();
        mapView=null;
        super.onDestroy();
    }
