1、构建定位Option的工具类
import com.baidu.location.LocationClientOption; public class LocationClientOptionBuilder { private LocationClientOption option; public static LocationClientOptionBuilder builder() { LocationClientOptionBuilder builder = new LocationClientOptionBuilder(); builder.option = builder.initOption(); return builder; } /** * 设置坐标系 * * @return * @see CoorType */ public LocationClientOptionBuilder setCoorType() { return setCoorType(CoorType.bd09ll); } public LocationClientOptionBuilder setCoorType(CoorType coorType) { this.option.setCoorType(coorType.name()); return this; } /** * 连续定位 * 可选,设置发起定位请求的间隔,int类型,单位ms * 如果设置为0,则代表单次定位,即仅定位一次,默认为0 * 如果设置非0,需设置1000ms以上才有效 * * @param time * @return */ public LocationClientOptionBuilder setScanSpan(int time) { this.option.setScanSpan(time); return this; } public LocationClientOption bulid() { return this.option; } private LocationClientOption initOption() { LocationClientOption option = new LocationClientOption(); //可选,设置定位模式,默认高精度 //LocationMode.Hight_Accuracy:高精度; //LocationMode. Battery_Saving:低功耗; //LocationMode. Device_Sensors:仅使用设备; option.setLocationMode(LocationClientOption.LocationMode.Hight_Accuracy); //可选,设置返回经纬度坐标类型,默认GCJ02 //GCJ02:国测局坐标; //BD09ll:百度经纬度坐标; //BD09:百度墨卡托坐标; //海外地区定位,无需设置坐标类型,统一返回WGS84类型坐标 // option.setCoorType("bd09ll"); //可选,设置发起定位请求的间隔,int类型,单位ms //如果设置为0,则代表单次定位,即仅定位一次,默认为0 //如果设置非0,需设置1000ms以上才有效 // option.setScanSpan(1000); //可选,设置是否使用gps,默认false //使用高精度和仅用设备两种定位模式的,参数必须设置为true option.setOpenGps(true); //可选,设置是否当GPS有效时按照1S/1次频率输出GPS结果,默认false // option.setLocationNotify(true); //可选,定位SDK内部是一个service,并放到了独立进程。 //设置是否在stop的时候杀死这个进程,默认(建议)不杀死,即setIgnoreKillProcess(true) // option.setIgnoreKillProcess(true); //可选,设置是否收集Crash信息,默认收集,即参数为false // option.SetIgnoreCacheException(false); //可选,V7.2版本新增能力 //如果设置了该接口,首次启动定位时,会先判断当前Wi-Fi是否超出有效期,若超出有效期,会先重新扫描Wi-Fi,然后定位 // option.setWifiCacheTimeOut(5 * 60 * 1000); //可选,设置是否需要过滤GPS仿真结果,默认需要,即参数为false // option.setEnableSimulateGps(false); return option; } /** * 坐标系 */ public enum CoorType { gcj02, bd09, bd09ll } }
2、构建定位的工具类
import android.content.Context; import android.support.annotation.NonNull; import android.util.Log; import com.baidu.location.BDAbstractLocationListener; import com.baidu.location.BDLocation; import com.baidu.location.LocationClient; import com.baidu.location.LocationClientOption; /** * 百度地图定位工具类 * * @author peter 2018-12-21 10:12 */ public class BMapLocationHelper { private static final int LOCATION_SUCCESS = 1; static final int LOCATION_FAIL = -1; private LocationClient mLocationClient; private MyLocationListener myListener = new MyLocationListener(); private LocationCallBack callBack; private BMapLocationHelper(LocationCallBack callBack) { this.callBack = callBack; } public static BMapLocationHelper create(@NonNull Context context, @NonNull LocationClientOption option, @NonNull LocationCallBack callBack) { BMapLocationHelper bMapLocationHelper = new BMapLocationHelper(callBack); LocationClient client = new LocationClient(context); client.setLocOption(option); //声明LocationClient类 client.registerLocationListener(bMapLocationHelper.myListener); bMapLocationHelper.mLocationClient = client; return bMapLocationHelper; } /** * 开始定位 */ public void locStart() { mLocationClient.start(); } /** * 停止定位 */ public void locStop() { mLocationClient.stop(); } public void locReStart() { mLocationClient.restart(); } public LocationClient getmLocationClient() { return mLocationClient; } /** * 地图定位结果监听类 */ public class MyLocationListener extends BDAbstractLocationListener { private static final String TAG = "MyLocationListener"; @Override public void onReceiveLocation(BDLocation location) { if (location == null) return; int locType = location.getLocType(); int status = LOCATION_SUCCESS; if (locType != 61 && locType != 161 && locType != 66) status = LOCATION_FAIL; String errMsg = getLocationResultMsg(locType); callBack.onReceiveLocation(status, location, errMsg); } @Override public void onLocDiagnosticMessage(int i, int i1, String s) { Log.i(TAG, "onLocDiagnosticMessage: " + i + "diaType:" + i1); callBack.onLocDiagnosticMessage(i, i1, getLocDiagnosticMessage(i, i1)); super.onLocDiagnosticMessage(i, i1, s); } } /** * 回调类 */ public abstract static class LocationCallBack { /** * 定位的结果 * * @param statusCode 状态码,1:定位成功,-1定位失败 * @param bdLocation 定位成功时返回的定位结果对象 * @param errMsg 定位失败时的错误信息,成功时则为null */ public abstract void onReceiveLocation(int statusCode, BDLocation bdLocation, String errMsg); /** * 错误的状态码 * <a>http://lbsyun.baidu.com/index.php?title=android-locsdk/guide/addition-func/error-code</a> * <p> * 回调定位诊断信息,开发者可以根据相关信息解决定位遇到的一些问题 * * @param locType 当前定位类型 * @param diagnosticType 诊断类型(1~9) * @param diagnosticMessage 具体的诊断信息释义 */ public void onLocDiagnosticMessage(int locType, int diagnosticType, String diagnosticMessage) { } } /** * 错误的状态码 * <a>http://lbsyun.baidu.com/index.php?title=android-locsdk/guide/addition-func/error-code</a> * * @param locType 当前定位类型 * @return String 定位成功或失败的信息 */ private String getLocationResultMsg(int locType) { switch (locType) { case 61: return "GPS定位结果,GPS定位成功"; case 62: return "无法获取有效定位依据,定位失败,请检查运营商网络或者WiFi网络是否正常开启,尝试重新请求定位"; case 63: return "网络异常,没有成功向服务器发起请求,请确认当前测试手机网络是否通畅,尝试重新请求定位"; case 66: return "离线定位结果。通过requestOfflineLocaiton调用时对应的返回结果"; case 67: return "离线定位失败"; case 161: return "网络定位结果,网络定位成功"; case 162: return "请求串密文解析失败,一般是由于客户端SO文件加载失败造成,请严格参照开发指南或demo开发,放入对应SO文件"; case 167: return "服务端定位失败,请您检查是否禁用获取位置信息权限,尝试重新请求定位"; case 505: return "AK不存在或者非法,请按照说明文档重新申请AK"; default: return ""; } } /** * @param locType 当前定位类型 * @param diagnosticType 诊断类型(1~9) * @return String */ private String getLocDiagnosticMessage(int locType, int diagnosticType) { switch (locType) { case 62: switch (diagnosticType) { case 4: return "定位失败,无法获取任何有效定位依据"; case 5: return "定位失败,无法获取有效定位依据,请检查运营商网络或者Wi-Fi网络是否正常开启,尝试重新请求定位"; case 6: return "定位失败,无法获取有效定位依据,请尝试插入一张sim卡或打开Wi-Fi重试"; case 7: return "定位失败,飞行模式下无法获取有效定位依据,请关闭飞行模式重试"; case 9: return "定位失败,无法获取任何有效定位依据"; } case 67: if (diagnosticType == 3) return "定位失败,请您检查您的网络状态"; case 161: switch (diagnosticType) { case 1: return "定位失败,建议您打开GPS"; case 2: return "定位失败,建议您打开Wi-Fi"; } case 167: if (diagnosticType == 8) return "定位失败,请确认您定位的开关打开状态,是否赋予APP定位权限"; default: return "未知错误"; } } }
3、显示用户当前位置到地图的工具类
import android.content.Context; import android.support.annotation.NonNull; import android.util.Log; import com.baidu.location.BDLocation; import com.baidu.location.LocationClientOption; import com.baidu.mapapi.map.BaiduMap; import com.baidu.mapapi.map.MapStatus; import com.baidu.mapapi.map.MapStatusUpdateFactory; import com.baidu.mapapi.map.MyLocationData; import com.baidu.mapapi.model.LatLng; import com.yikesong.sender.util.ToastUtils; /** * 显示用户当前位置到地图上 * * @author peter 2018-12-21 16:27 */ public class UserLocation extends BMapLocationHelper.LocationCallBack { private Context context; private boolean isFirstLoc = true; private BaiduMap map; private int mCurrentDirection = 0; private BMapLocationHelper helper; private static final String TAG = "UserLocation"; public UserLocation(@NonNull Context context, @NonNull BaiduMap map) { this.context = context; this.map = map; init(); } private void init() { map.setMapType(BaiduMap.MAP_TYPE_NORMAL); //开启定位图层 map.setMyLocationEnabled(true); } /** * 在地图上显示用户的当前位置 */ public void showUserLocationOnMap() { if (helper == null) { LocationClientOption option = LocationClientOptionBuilder .builder() .setCoorType() .bulid(); helper = BMapLocationHelper.create(this.context, option, this); } helper.locStart(); } @Override public void onReceiveLocation(int statusCode, BDLocation bdLocation, String errMsg) { if (statusCode == BMapLocationHelper.LOCATION_FAIL) { ToastUtils.toastInfo(errMsg, context); Log.i(TAG, "onReceiveLocation: " + errMsg); return; } MyLocationData locData = new MyLocationData.Builder() .accuracy(bdLocation.getRadius()) // 此处设置开发者获取到的方向信息,顺时针0-360 .direction(mCurrentDirection).latitude(bdLocation.getLatitude()) .longitude(bdLocation.getLongitude()).build(); map.setMyLocationData(locData); if (isFirstLoc) { isFirstLoc = false; LatLng centerPoint = new LatLng(bdLocation.getLatitude(), bdLocation.getLongitude()); MapStatus mapStatus = new MapStatus.Builder() .target(centerPoint) //设置中心点 .zoom(18f)//设置缩放级别 .build(); map.animateMapStatus(MapStatusUpdateFactory.newMapStatus(mapStatus)); } if (helper != null) helper.locStop(); } @Override public void onLocDiagnosticMessage(int locType, int diagnosticType, String diagnosticMessage) { super.onLocDiagnosticMessage(locType, diagnosticType, diagnosticMessage); } public BMapLocationHelper getHelper() { return helper; } public BaiduMap getMap() { return map; } public int getmCurrentDirection() { return mCurrentDirection; } }
