1.获取AK

发布版:

keytool -v -list -keystore key.jks

SHA1:A9:7D:70:70:4C:67:83:71:AC:FD:18:6E:EF:9B:08:FF:CF:07:A6:BD

开发版:

keytool -v -list -keystore debug.keystore

SHA1:39:FC:60:2A:FA:CB:BF:6C:79:CA:98:58:C6:2F:F8:58:FE:56:24:2F

2.创建定位测试项目

1)AndroidManifest.xml

增加权限,声明service和ak鉴权

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.READ_PHONE_STATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >
    </uses-permission>
    <uses-permission android:name="android.permission.INTERNET" >
    </uses-permission>
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" >
    </uses-permission>
    <uses-permission android:name="android.permission.READ_LOGS" >
    </uses-permission>
    <uses-permission android:name="android.permission.VIBRATE" >
    </uses-permission>
    <uses-permission android:name="android.permission.WAKE_LOCK" >
    </uses-permission>
    <uses-permission android:name="android.permission.WRITE_SETTINGS" >
    </uses-permission>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

        <!-- 声明service组件 -->
        <service
            android:name="com.baidu.location.f"
            android:enabled="true"
            android:process=":remote" >
        </service>
        <!-- AK鉴权 -->
        <!-- meta-data需要写在application中 -->
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="V57HWvyoHwUYEK15Nws2kAZYvSwWtC2q" />

2)导入项目所需的jar包和so

BaiduLBS_Android.jar

libBaiduMapSDK_base_v4_5_2.so

libBaiduMapSDK_map_v4_5_2.so

liblocSDK7b.so

在app的build.gradle android{}中说明so为该libs路径

android {
    ...
    sourceSets {
        main {
            jniLibs.srcDir 'libs'
        }
    }
}

3.定位流程

1)初始化LocationClient类

LocationClient类最好在主线程中声明，需要Context类型的参数。

Context需要时全进程有效的Context,推荐用getApplicationConext获取全进程有效的Context

mLocClient = new LocationClient(getApplicationContext());
mLocClient.registerLocationListener(listener);

2)配置SDK参数

LocationClientOption option = new LocationClientOption();
        option.setIsNeedAddress(true);//是否要地址
        option.setOpenGps(true);
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(1000);//可选，默认0，即仅定位一次，设置发起连续定位请求的间隔需要大于等于1000ms才是有效的
        mLocClient.setLocOption(option);
        mLocClient.start();

3)实现BDAbstractLocationListener接口

Android定位SDK自v7.2版本起，对外提供了Abstract类型的监听接口BDAbstractLocationListener，用于实现定位监听。原有BDLocationListener暂时保留，推荐开发者升级到Abstract类型的新监听接口使用，该接口会异步获取定位结果

@Override
        public void onReceiveLocation(BDLocation bdLocation) {

            Log.i("bdmap","定位类型:"+bdLocation.getLocTypeDescription()+"\n"
                            +"纬度:"+bdLocation.getLatitude()+"\n"
                            +"经度:"+bdLocation.getLongitude()+"\n"
                            +"详细地址:"+bdLocation.getAddrStr()+"\n"
                            +"卫星数目"+bdLocation.getSatelliteNumber());
}
输出:
I/bdmap: 定位类型:GPS location successful!
纬度:30.555669
经度:104.075068
详细地址:中国四川省成都市武侯区G213(xxxxxx)
卫星数目4

4.增加Mark

LatLng ll = new LatLng(bdLocation.getLatitude(),
                        bdLocation.getLongitude());
BitmapDescriptor bitmap = BitmapDescriptorFactory.fromResource(R.mipmap.icon_openmap_mark);
                // 构建MarkerOption，用于在地图上添加Marker
                OverlayOptions option = new MarkerOptions()
                        .position(ll) //mark出现的位置
                        .icon(bitmap) //mark图标
                        .draggable(true);//mark可拖动
                //在地图上添加Marker并显示
                mBaiduMap.addOverlay(option);

//对Marker的点击事件
        mBaiduMap.setOnMarkerClickListener(new BaiduMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {
                //获取marker中的数据
                double lat = marker.getPosition().latitude;
                double log = marker.getPosition().longitude;
                Toast.makeText(getApplication(),
                        "经度"+log+" 纬度"+lat,Toast.LENGTH_LONG)
                        .show();
                return false;
            }
        });

5.Demo

public class MainActivity extends AppCompatActivity {
    private MapView mMapView = null;
    private BaiduMap mBaiduMap = null;
    boolean isFirstLoc = true; // 是否首次定位
    LocationClient mLocClient;
    private MyLocationData locData; //定位数据包
    private Marker marker;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SDKInitializer.initialize(getApplicationContext());
        setContentView(R.layout.activity_main);

        mMapView = (MapView)findViewById(R.id.bmapView);
        mBaiduMap = mMapView.getMap();
        //设置类型
        mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);
        mBaiduMap.setMapStatus(MapStatusUpdateFactory.zoomTo(17));
        // 开启定位图层
        mBaiduMap.setMyLocationEnabled(true);

        mLocClient = new LocationClient(getApplicationContext());
        mLocClient.registerLocationListener(listener);
        LocationClientOption option = new LocationClientOption();
        option.setIsNeedAddress(true);//是否要地址
        option.setOpenGps(true);
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(1000);//可选，默认0，即仅定位一次，设置发起连续定位请求的间隔需要大于等于1000ms才是有效的
        mLocClient.setLocOption(option);
        mLocClient.start();
        //对Marker的点击事件
        mBaiduMap.setOnMarkerClickListener(new BaiduMap.OnMarkerClickListener() {
            @Override
            public boolean onMarkerClick(Marker marker) {
                //获取marker中的数据
                double lat = marker.getPosition().latitude;
                double log = marker.getPosition().longitude;
                Toast.makeText(getApplication(),
                        "经度"+log+" 纬度"+lat,Toast.LENGTH_LONG)
                        .show();
                return false;
            }
        });
        //Map点击事件,点击地图移除marker
        mBaiduMap.setOnMapClickListener(new BaiduMap.OnMapClickListener() {
            @Override
            public void onMapClick(LatLng latLng) {
                marker.remove();//移除marker
            }

            @Override
            public boolean onMapPoiClick(MapPoi mapPoi) {
                return false;
            }
        });

    }

    /***
     * 定位结果回调，在此方法中处理定位结果
     */
    BDAbstractLocationListener listener = new BDAbstractLocationListener() {
        @Override
        public void onReceiveLocation(BDLocation bdLocation) {

            Log.i("bdmap","定位类型:"+bdLocation.getLocTypeDescription()+"\n"

            //构造定位数据
            locData = new MyLocationData.Builder()
                    .accuracy(bdLocation.getRadius())
                    .latitude(bdLocation.getLatitude())
                    .longitude(bdLocation.getLongitude())
                    .build();
            mBaiduMap.setMyLocationData(locData);


            if (isFirstLoc) {
                isFirstLoc = false;
                LatLng ll = new LatLng(bdLocation.getLatitude(),

                BitmapDescriptor bitmap = BitmapDescriptorFactory.fromResource(R.mipmap.icon_openmap_mark);
                // 构建MarkerOption，用于在地图上添加Marker
                OverlayOptions option = new MarkerOptions()
                        .position(ll) //mark出现的位置

            }
        }
    };

    @Override
