融合定位开发

配置权限

动态申请定位权限

 //动态申请权限private void setIntegration() {if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.P) {Log.i(TAG, "android sdk <= 28 Q");if (ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED&& ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {String[] strings ={Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION};ActivityCompat.requestPermissions(this, strings, 1);}} else {// Android SDK>28 所需权限动态申请，需添加“android.permission.ACCESS_BACKGROUND_LOCATION”权限if (ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED&& ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED&& ActivityCompat.checkSelfPermission(this,"android.permission.ACCESS_BACKGROUND_LOCATION") != PackageManager.PERMISSION_GRANTED) {String[] strings = {Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION,"android.permission.ACCESS_BACKGROUND_LOCATION"};ActivityCompat.requestPermissions(this, strings, 2);}}}

检查设备定位开关状态

private void locationFunction() {SettingsClient settingsClient = LocationServices.getSettingsClient(this);LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();LocationRequest mLocationRequest = new LocationRequest();builder.addLocationRequest(mLocationRequest);LocationSettingsRequest locationSettingsRequest = builder.build();// 检查设备定位设置settingsClient.checkLocationSettings(locationSettingsRequest)// 检查设备定位设置接口调用成功监听.addOnSuccessListener(new OnSuccessListener<LocationSettingsResponse>() {@Overridepublic void onSuccess(LocationSettingsResponse locationSettingsResponse) {Log.i(TAG, "onSuccess: 成功！");LocationSettingsStates locationSettingsStates =locationSettingsResponse.getLocationSettingsStates();StringBuilder stringBuilder = new StringBuilder();// 定位开关是否打开stringBuilder.append(",\nisLocationUsable=").append(locationSettingsStates.isLocationUsable());// HMS Core是否可用stringBuilder.append(",\nisHMSLocationUsable=").append(locationSettingsStates.isHMSLocationUsable());Log.i(TAG, "checkLocationSetting onComplete:" + stringBuilder.toString());Log.i(TAG, "onSuccess: locationSettingsResponse=====" + locationSettingsResponse.toString());}})// 检查设备定位设置接口失败监听回调.addOnFailureListener(new OnFailureListener() {@Overridepublic void onFailure(Exception e) {Log.i(TAG, "checkLocationSetting onFailure:失败！！！！！！！" + e.getMessage());}});}

获取当前定位服务

 //获取当前定位服务private void positioningFunction() {FusedLocationProviderClient fusedLocationProviderClient = new FusedLocationProviderClient(this);LocationRequest mLocationRequest = new LocationRequest();设置定位类型mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);//设置定位类型  高进度
// 设置回调次数为1
//        mLocationRequest.setNumUpdates(1);mLocationRequest.setInterval(10000);//持续定位LocationCallback locationCallback = new LocationCallback() {@Overridepublic void onLocationResult(LocationResult locationResult) {Location lastLocation = locationResult.getLastLocation();//打印当前设备的经纬度Log.i(TAG, "onLocationResult: 定位位置" + lastLocation.getLongitude() +"=="+ lastLocation.getLatitude());}};//介绍了两种方法   以教辅资料为准  开发文档为辅助
//        Task<Location> lastLocation = fusedLocationProviderClient.getLastLocation();
//        lastLocation.addOnSuccessListener(new )fusedLocationProviderClient.requestLocationUpdates(mLocationRequest, locationCallback, Looper.getMainLooper());}
