Android 系统定位和高德定位

系统定位

工具类

public class LocationUtils {public static final int REQUEST_LOCATION = 0xa1;/*** 判断定位服务是否开启*/public static boolean isOpenLocationServer(Context context) {int locationMode = 0;try {locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);} catch (Settings.SettingNotFoundException e) {e.printStackTrace();return false;}return locationMode != Settings.Secure.LOCATION_MODE_OFF;}/*** 判断GPS是否可用*/public static boolean isGPSEnabled(Context context) {LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);return manager.isProviderEnabled(LocationManager.GPS_PROVIDER);}/*** 判断定位是否可用*/public static boolean isLocationEnabled(Context context) {LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);return manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) || manager.isProviderEnabled(LocationManager.GPS_PROVIDER);}/*** 开启位置服务*/public static void openLocation(Activity activity) {activity.startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), REQUEST_LOCATION);}/*** 开启位置服务*/public static void openLocation(Fragment fragment) {fragment.startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), REQUEST_LOCATION);}}

封装LocationManager

public class LocationHelper {private static OnLocationChangeListener mOnLocationChangeListener;private static MyLocationListener mLocationListener;private static LocationManager mLocationManager;private static String mProvider;/*** 注册*/public static void registerLocation(Context context, @Nullable OnLocationChangeListener listener) {mOnLocationChangeListener = listener;mLocationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);mProvider = mLocationManager.getBestProvider(getCriteria(), true);Location lastKnownLocation = mLocationManager.getLastKnownLocation(mProvider);if (listener != null && lastKnownLocation != null) {listener.onLastKnownLocation(lastKnownLocation);}mLocationListener = new MyLocationListener();startLocation();}/*** 开始定位*/public static void startLocation() {// 第二个参数：更新定位的时间间隔，第三个参数：更新定位的距离范围mLocationManager.requestLocationUpdates(mProvider, 0, 0, mLocationListener);}/*** 停止定位*/public static void stopLocation() {mLocationManager.removeUpdates(mLocationListener);}/*** 设置定位参数** @return {@link Criteria}*/private static Criteria getCriteria() {Criteria criteria = new Criteria();// 设置定位精确度 Criteria.ACCURACY_COARSE比较粗略，Criteria.ACCURACY_FINE则比较精细criteria.setAccuracy(Criteria.ACCURACY_FINE);// 设置是否要求速度criteria.setSpeedRequired(false);// 设置是否允许运营商收费criteria.setCostAllowed(false);// 设置是否需要方位信息criteria.setBearingRequired(false);// 设置是否需要海拔信息criteria.setAltitudeRequired(false);// 设置对电源的需求criteria.setPowerRequirement(Criteria.POWER_LOW);return criteria;}/*** 取消注册*/public static void unregisterLocation() {if (mLocationManager != null) {if (mLocationListener != null) {mLocationManager.removeUpdates(mLocationListener);}}mLocationManager = null;mLocationListener = null;mOnLocationChangeListener = null;}public interface OnLocationChangeListener {void onLastKnownLocation(Location location);void onLocationChanged(Location location);}public static class MyLocationListener implements LocationListener {@Overridepublic void onLocationChanged(@NonNull Location location) {if (mOnLocationChangeListener != null) {mOnLocationChangeListener.onLocationChanged(location);}}}
}

public class LocationService extends Service {public static void actionStart(Context context) {context.startService(new Intent(context, LocationService.class));}public static void actionStop(Context context) {context.stopService(new Intent(context, LocationService.class));}@SuppressLint("MissingPermission")@Overridepublic void onCreate() {super.onCreate();new Thread(() -> {Looper.prepare();LocationHelper.registerLocation(getApplicationContext(), new LocationHelper.OnLocationChangeListener() {@Overridepublic void onLastKnownLocation(Location location) {if (location != null) {Log.e("TAG", "onLastKnownLocation= " + location);}}@Overridepublic void onLocationChanged(Location location) {if (location != null) {Log.e("TAG", "onLocationChanged= " + location);stopSelf();}}});Looper.loop();}).start();}@Nullable@Overridepublic IBinder onBind(Intent intent) {return null;}@Overridepublic void onDestroy() {super.onDestroy();LocationHelper.unregisterLocation();}
}

使用

// 开始定位
LocationService.actionStart(MainActivity.this, "start");// 停止定位
LocationService.actionStart(MainActivity.this, "stop");// 单次定位
LocationService.actionStart(MainActivity.this, "once");

高德定位
