定位成功，回调监听：

 @Overridepublic void onLocationChanged(AMapLocation amapLocation) {if (amapLocation != null) {if (amapLocation.getErrorCode() == 0) {//定位成功回调信息，设置相关消息amapLocation.getLocationType();//获取当前定位结果来源，如网络定位结果，详见定位类型表amapLocation.getLatitude();//获取纬度amapLocation.getLongitude();//获取经度amapLocation.getAccuracy();//获取精度信息SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date date = new Date(amapLocation.getTime());df.format(date);//定位时间// 如果不设置标志位，此时再拖动地图时，它会不断将地图移动到当前的位置//设置缩放级别aMap.moveCamera(CameraUpdateFactory.zoomTo(12));//将地图移动到定位点aMap.moveCamera(CameraUpdateFactory.changeLatLng(new LatLng(amapLocation.getLatitude(), amapLocation.getLongitude())));LatLng latLng = new LatLng(amapLocation.getLatitude(), amapLocation.getLongitude());latLonPoint = latLng;//在地图中设置定位坐标点MarkerOptions markerOption = new MarkerOptions();markerOption.position(latLng);markerOption.draggable(true);markerOption.icon(BitmapDescriptorFactory.fromResource(R.mipmap.dingwei));markerOption.title(amapLocation.getPoiName()).snippet(amapLocation.getAddress());Marker marker = aMap.addMarker(markerOption);marker.setRotateAngle(0);//定位成功，开启检测功能startSearch(amapLocation.getLatitude(), amapLocation.getLongitude());} else {//显示错误信息ErrCode是错误码，errInfo是错误信息，详见错误码表。Log.e("AmapError", "location Error, ErrCode:"+ amapLocation.getErrorCode() + ", errInfo:"+ amapLocation.getErrorInfo());}}}

在定位回调中开启检测功能

startSearch(amapLocation.getLatitude(), amapLocation.getLongitude());

 private void startSearch(double Latitude, double Longitude) {PoiSearch.Query query = new PoiSearch.Query("加油站", "汽车维修|修车服务", "");// keyWord表示搜索字符串，第二个参数表示POI搜索类型，默认为：生活服务、餐饮服务、商务住宅// 共分为以下20种：汽车服务|汽车销售|// 汽车维修|摩托车服务|餐饮服务|购物服务|生活服务|体育休闲服务|医疗保健服务|// 住宿服务|风景名胜|商务住宅|政府机构及社会团体|科教文化服务|交通设施服务|// 金融保险服务|公司企业|道路附属设施|地名地址信息|公共设施// cityCode表示POI搜索区域，（这里可以传空字符串，空字符串代表全国在全国范围内进行搜索）query.setPageSize(10);// 设置每页最多返回多少条poiitemquery.setPageNum(1);// 设置查第一页PoiSearch poiSearch = new PoiSearch(this, query);//如果不为空值if (Latitude != 0.0 && Longitude != 0.0) {poiSearch.setBound(new PoiSearch.SearchBound(new LatLonPoint(Latitude,Longitude), 6000));// 设置周边搜索的中心点以及区域poiSearch.setOnPoiSearchListener(this);// 设置数据返回的监听器poiSearch.searchPOIAsyn();// 开始搜索} else {
//            Toast.makeText(SearchActivity.this, "定位失败", 0).show();}}

检索成功后，在地图上设置涂点：

 @Overridepublic void onPoiSearched(PoiResult poiResult, int i) {//结果if (poiResult.getPois() == null)return;ArrayList<PoiItem> poiItems = poiResult.getPois();for (PoiItem a : poiItems) {addMarkerToMap(a);}}private void addMarkerToMap(PoiItem a) {LatLng latLng = new LatLng(a.getLatLonPoint().getLatitude(), a.getLatLonPoint().getLongitude());MarkerOptions markerOption = new MarkerOptions();markerOption.position(latLng);markerOption.draggable(true);markerOption.icon(BitmapDescriptorFactory.fromResource(R.mipmap.icon_location));markerOption.title(a.getCityName()).snippet(a.getBusinessArea());Marker marker = aMap.addMarker(markerOption);marker.setRotateAngle(0);//显示InfoWindow}

接下来是目标点点击事件，这里我采用了点击后弹出自定义弹窗：

 @Overridepublic View getInfoWindow(final Marker marker) {View view = getLayoutInflater().inflate(R.layout.bdmap_node_popwindow,null);view.findViewById(R.id.item3).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {naviMapStart(marker);}});return view;}@Overridepublic View getInfoContents(final Marker marker) {View view = getLayoutInflater().inflate(R.layout.bdmap_node_popwindow,null);
//        TextView title = (TextView) view.findViewById(R.id.title);
//        title.setText(marker.getTitle());view.findViewById(R.id.item3).setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {naviMapStart(marker);}});return view;}

注意：设置自定义弹窗首先要先设置监听，让高德来拿取我们自定义的view,这里很坑，卡了我3、4个小时。

//设置自定义view事件
aMap.setInfoWindowAdapter(this);

当然activity需要继承接口AMap.InfoWindowAdapter。

public class AMapNaviActivity extends NaviBaseActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_amap_navi);mAMapNaviView = (AMapNaviView) findViewById(R.id.navi_view);mAMapNaviView.onCreate(savedInstanceState);mAMapNaviView.setAMapNaviViewListener(this);AMapNaviViewOptions options = mAMapNaviView.getViewOptions();options.setLayoutVisible(false);mAMapNaviView.setViewOptions(options);}public void northUp(View view) {mAMapNaviView.setNaviMode(AMapNaviView.NORTH_UP_MODE);}public void carUp(View view) {mAMapNaviView.setNaviMode(AMapNaviView.CAR_UP_MODE);}@Overridepublic void onInitNaviSuccess() {super.onInitNaviSuccess();/*** 方法: int strategy=mAMapNavi.strategyConvert(congestion, avoidhightspeed, cost, hightspeed, multipleroute); 参数:** @congestion 躲避拥堵* @avoidhightspeed 不走高速* @cost 避免收费* @hightspeed 高速优先* @multipleroute 多路径**  说明: 以上参数都是boolean类型，其中multipleroute参数表示是否多条路线，如果为true则此策略会算出多条路线。*  注意: 不走高速与高速优先不能同时为true 高速优先与避免收费不能同时为true*/int strategy = 0;try {//再次强调，最后一个参数为true时代表多路径，否则代表单路径strategy = mAMapNavi.strategyConvert(true, false, false, false, false);} catch (Exception e) {e.printStackTrace();}mAMapNavi.calculateDriveRoute(SearchActivity.startPoints , SearchActivity.endPoints , mWayPointList, strategy);}@Overridepublic void onCalculateRouteSuccess() {super.onCalculateRouteSuccess();mAMapNavi.startNavi(NaviType.GPS);}
}

其中继承的类为：

public class NaviBaseActivity extends Activity implements AMapNaviListener, AMapNaviViewListener {protected AMapNaviView mAMapNaviView;protected AMapNavi mAMapNavi;
//    protected TTSController mTtsManager;protected  List<NaviLatLng> sList = new ArrayList<NaviLatLng>();protected  List<NaviLatLng> eList = new ArrayList<NaviLatLng>();protected List<NaviLatLng> mWayPointList;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);
//        //实例化语音引擎
//        mTtsManager = TTSController.getInstance(getApplicationContext());
//        mTtsManager.init();//mAMapNavi = AMapNavi.getInstance(getApplicationContext());mAMapNavi.addAMapNaviListener(this);
//        mAMapNavi.addAMapNaviListener(mTtsManager);//设置模拟导航的行车速度mAMapNavi.setEmulatorNaviSpeed(75);}@Overrideprotected void onResume() {super.onResume();mAMapNaviView.onResume();}@Overrideprotected void onPause() {super.onPause();mAMapNaviView.onPause();//        仅仅是停止你当前在说的这句话，一会到新的路口还是会再说的
//        mTtsManager.stopSpeaking();
//
//        停止导航之后，会触及底层stop，然后就不会再有回调了，但是讯飞当前还是没有说完的半句话还是会说完
//        mAMapNavi.stopNavi();}@Overrideprotected void onDestroy() {super.onDestroy();mAMapNaviView.onDestroy();//since 1.6.0 不再在naviview destroy的时候自动执行AMapNavi.stopNavi();请自行执行mAMapNavi.stopNavi();mAMapNavi.destroy();

到这里简单的导航工具就搞定了，接下来就是在主界面进行调用导航功能：

    private void naviMapStart(Marker marker) {// 导航// 起点终点列表ArrayList<NaviLatLng> startPoints = new ArrayList<NaviLatLng>();ArrayList<NaviLatLng> endPoints = new ArrayList<NaviLatLng>();LatLng endLatLng = marker.getPosition();NaviLatLng endNaviLatLng = new NaviLatLng(endLatLng.latitude,endLatLng.longitude);endPoints.add(endNaviLatLng);NaviLatLng startNaviLatLng = new NaviLatLng(latLonPoint.latitude,latLonPoint.longitude);startPoints.add(startNaviLatLng);// DrivingSaveMoney--省钱// DrivingShortDistance--最短距离// DrivingNoExpressways--不走高速// DrivingFastestTime--最短时间// DrivingAvoidCongestion--避免拥堵//        AMapNavi.getInstance(SearchActivity.this)
//                .calculateDriveRoute(startPoints, endPoints, null,
//                        AMapNavi.DrivingShortDistance);SearchActivity.startPoints = startPoints;SearchActivity.endPoints = endPoints;Intent intent = new Intent(SearchActivity.this,AMapNaviActivity.class);startActivity(intent);}

致此高德地图关于地图使用，定位功能，检索功能，导航功能就完成了。
