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

这里写图片描述

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" +"纬度:"+bdLocation.getLatitude()+"\n" +"经度:"+bdLocation.getLongitude()+"\n" +"详细地址:"+bdLocation.getAddrStr()+"\n" +"卫星数目"+bdLocation.getSatelliteNumber()); //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(), 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 marker = (Marker) mBaiduMap.addOverlay(option); MapStatus.Builder builder = new MapStatus.Builder(); builder.target(ll).zoom(17.0f); mBaiduMap.animateMapStatus(MapStatusUpdateFactory.newMapStatus(builder.build())); } } }; @Override protected void onDestroy() { //退出时销毁定位 mLocClient.stop(); //关闭定位图层 mBaiduMap.setMyLocationEnabled(false); mMapView.onDestroy(); mMapView = null; super.onDestroy(); } @Override protected void onResume() { super.onResume(); mMapView.onResume(); } @Override protected void onPause() { super.onPause(); mMapView.onPause(); } }
