百度地图

1.申请密钥

cd .androidkeytool -list -v -keystore debug.keystore复制开发版SHA1值 42:28:A5:A3:30:54:7D:71:FA:31:4D:58:4C:8C:5A:45:0F:94:89:89keytool -list -v -keystore 发布版SHA1路径(需要打包生成)输入密钥库口令: 生成APK的第一个密码2E:F8:95:77:E2:4B:CB:A2:26:8B:28:A8:86:EF:DE:B1:FD:67:A6:5A---->XA5dNxGrhB006qGiM4TCNKDv39I8G1Wi

2.下载SDK

解压到libs目录下依赖jar文件在build.gradle的android闭包中添加    sourceSets{        main{            jniLibs.srcDirs = ['libs']        }    }

3.搭建基础地图

    1.在application节点中中添加开发密钥<application>      <meta-data          android:name="com.baidu.lbsapi.API_KEY"          android:value="第一步申请到的 key" />  </application>    2.添加所需权限    <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" />    3.第三步，在布局xml文件中添加地图控件；<com.baidu.mapapi.map.MapView      android:id="@+id/bmapView"      android:layout_width="fill_parent"      android:layout_height="fill_parent"      android:clickable="true" />    4.在MyApp初始化SDK，并引用AppName    public class MyApp extends Application {    @Override    public void onCreate() {        super.onCreate();        SDKInitializer.initialize(this);    }}    5.创建地图Activity，管理地图生命周期；与Activity同步    public class Baidu extends AppCompatActivity {    MapView mapView;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        mapView = (MapView) findViewById(R.id.mv);    }    @Override    protected void onPause() {        super.onPause();        mapView.onPause();    }    @Override    protected void onResume() {        super.onResume();        mapView.onResume();    }    @Override    protected void onDestroy() {        super.onDestroy();        mapView.onDestroy();    }}

4. 设置地图

    //地图控制类    BaiduMap baiduMap = mapView.getMap();    //空白地图    mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NONE);    //普通地图    mBaiduMap.setMapType(BaiduMap.MAP_TYPE_NORMAL);      //卫星地图    mBaiduMap.setMapType(BaiduMap.MAP_TYPE_SATELLITE);      //交通地图    mBaiduMap.setTrafficEnabled(true);    //热力图    mBaiduMap.setBaiduHeatMapEnabled(true);    //Marker坐标点    public static final LatLng xykj = new LatLng(22.536294,113.95137);    //Marker图标    private static final BitmapDesceriptor xykjBitmap = BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher_round);    //创建一组Marker图标    ArrayList<BitmapDescriptor> list = new ArrayList<>();            for (int i = 0; i < 10; i++) {            try {                int id = R.drawable.class.getField("icon_mark" + (char)('a'+i)).getInt(null);                list.add(BitmapDescriptorFactory.fromResource(id));            } catch (Exception e) {                e.printStackTrace();            }        }    //添加Marker标记    OverlayOptions option = new MarkerOptions().position(xykj)        .icon(xykjBitmap);  //一张图片        .icons(list);   //一组图片        .animateType(MarkerOptions.MarkerAnimateType.drop);//从天而降     baiduMap.addOverlay(option);    //添加文本标记    OverlayOptions overlayOptions = new TextOptions().position(xykj).text("武汉大学")            .fontSize(18).bgColor(Color.BLUE)            .fontColor(Color.RED);        Text text = (Text) baiduMap.addOverlay(overlayOptions);    //添加一个圆到地图    OverlayOptions overlayOptions1 = new CircleOptions().center(latLng).fillColor(Color.argb(0x60, 0xff, 0x00, 0xff))         .radius(2000)         .stroke(new Stroke(Color.GRAY, 10));     baiduMap.addOverlay(overlayOptions1);    //添加一个折线        List<Integer> colorList = new ArrayList<>();        List<LatLng> lineList = new LinkedList<>();        lineList.add(new LatLng(22, 113));        lineList.add(new LatLng(22.536294, 113.95137));        lineList.add(new LatLng(23, 114));        colorList.add(Color.RED);        colorList.add(Color.GREEN);        PolylineOptions points = new PolylineOptions().colorsValues(colorList).points(lineList);        baiduMap.addOverlay(points);     //设置百度地图的当前位置     baiduMap.setMapStatus(MapStatusUpdateFactory.newLatLngZoom(xykj,18));     //mipmap和drawable不区分图片大小     // MapFragment 和 MapView 的区别

5.POI检索

        1. 创建POI检索实例            PoiSearch poiSearch = PoiSearch.newInstance();            2. 设置POI检索监听，监听请求后的结果            OnGetPoiSearchResultListener poiListener = new OnGetPoiSearchResultListener() {            @Override            public void onGetPoiResult(PoiResult poiResult) {                //获取POI检索结果                List<PoiInfo> allPoi = poiResult.getAllPoi();            }            @Override            public void onGetPoiDetailResult(PoiDetailResult poiDetailResult) {                //获取Place详情页检索结果                    if (result.error != SearchResult.ERRORNO.NO_ERROR) {                    //详情检索失败                    // result.error请参考SearchResult.ERRORNO                 }                 else {                    //检索成功                }            }            @Override            public void onGetPoiIndoorResult(PoiIndoorResult poiIndoorResult) {            }        };        poiSearch.setOnGetPoiSearchResultListener(poiListener);            3. 发送POI请求            // 1. 区域        poiSearch.searchInBound(new PoiBoundSearchOption()                .bound(new LatLngBounds.Builder().include(xykj).include(zhongshan).build())                .keyword("超市"));            // 2. 周边        poiSearch.searchNearby(new PoiNearbySearchOption()                .location(zhongshan)                .keyword("公园")                .radius(20000)                .pageNum(2));            // 3. 城市        poiSearch.searchInCity(new PoiCitySearchOption()                .city("纽约")                .keyword("超市"));            // 4. 发送POI详情检索请求        poiSearch.searchPoiDetail(new PoiDetailSearchOption().poiUid(poiInfo.uid));        // 4. 释放POI检索实例        poiSearch.destroy();

6.路线规划

            1. 初始化路线规划实例            RoutePlanSearch routePlanSearch = RoutePlanSearch.newInstance();            2. 设置规划请求后的监听，共有6个方案            routePlanSearch.setOnGetRoutePlanResultListener(this);            // 驾车、步行、公交、骑行、跨城综合、室内路线搜索            3. 发出规划请求                //跨城                    mSearch.masstransitSearch(new MassTransitRoutePlanOption()                    .from(PlanNode.withCityNameAndPlaceName("北京", "天安门"))                    .to(PlanNode.withCityNameAndPlaceName("上海", "东方明珠")));                //驾车                    mSearch.drivingSearch((new DrivingRoutePlanOption())                    .from(stNode).to(enNode));                //公交                    mSearch.transitSearch((new TransitRoutePlanOption())                    .from(stNode).city("北京").to(enNode));                //步行                            mSearch.walkingSearch((new WalkingRoutePlanOption())                    .from(stNode).to(enNode));                //骑行                    mSearch.bikingSearch((new BikingRoutePlanOption())                    .from(stNode).to(enNode));            4. 销毁                mSearch.destroy();

7.定位

        1. 使用SourceSets
