首先第一步要添加权限<uses-permission android:name='android.permission.ACCESS_FINE_LOCATION'/><uses-permission android:name='android.permission.ACCESS_COARSE_LOCATION'/> 第二步是要获取权限因为咱们的6.0及以上的版本把这一类的权限定义为敏感权限/危险权限，所以在6.0之后我们要去动态去获取权限，这一步就省略了 ，如果还有小伙伴还不知道去动态获取权限 翻看下我之前的博客 略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略略。 第三步就是直接封装个工具类 用的时候可以直接调用新建一个 LocationUtils 类 public class LocationUtils {private LocationManager locationManager;static LocationUtils locationUtils;public static LocationUtils getInstance() {if (locationUtils == null) {locationUtils = new LocationUtils();}return locationUtils;}public ArrayList<String> getLocations(Context context) {ArrayList<String> strings=new ArrayList<>();if (!isOPenGPS(context)){Toast.makeText(context, '未开启定位，无法获取地理位置', Toast.LENGTH_SHORT).show();return strings;}String strLocation = '';DecimalFormat df = new DecimalFormat('#####0.0000');if (!checkPermission(context, permission.ACCESS_COARSE_LOCATION)) {Toast.makeText(context, '定位权限关闭，无法获取地理位置', Toast.LENGTH_SHORT).show();}try {//获取系统的服务，locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);//创建一个criteria对象Criteria criteria = new Criteria();criteria.setAccuracy(Criteria.ACCURACY_COARSE);//设置不需要获取海拔方向数据criteria.setAltitudeRequired(false);criteria.setBearingRequired(false);//设置允许产生资费criteria.setCostAllowed(true);//要求低耗电criteria.setPowerRequirement(Criteria.POWER_LOW);String provider = locationManager.getBestProvider(criteria, true);Log.e('wqs', 'Location Provider is ' + provider);@SuppressLint('MissingPermission') Location location = locationManager.getLastKnownLocation(provider);Log.w('wqs', '经纬度信息: ' + location.getLatitude()+'---'+location.getLongitude());/** * 重要函数，监听数据测试 *

public void run() {// lm.removeUpdates(locationListener);// }// },2000);//第一次获得设备的位置if (location != null) {// strLocation = df.format(location.getLatitude()) + ',' + df.format(location.getLongitude());// 耗时操作strLocation += '' + getLocationAddress(context, location);if (strLocation.equals('')) {strLocation += '' + convertAddress(context, location.getLatitude(), location.getLongitude());}}strings.add(strLocation);strings.add(location.getLatitude()+'/'+location.getLongitude());} catch (SecurityException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}return strings;}/** * @param latitude 经度 * @param longitude 纬度 * @return 详细位置信息 GeoCoder是基于后台backend的服务，因此这个方法不是对每台设备都适用。 */public String convertAddress(Context context, double latitude, double longitude) {Geocoder mGeocoder = new Geocoder(context, Locale.getDefault());StringBuilder mStringBuilder = new StringBuilder();try {List<Address> mAddresses = mGeocoder.getFromLocation(latitude, longitude, 1);if (!mAddresses.isEmpty()) {Address address = mAddresses.get(0);mStringBuilder.append(address.getLocality()).append(address.getThoroughfare());}} catch (IOException e) {e.printStackTrace();}return mStringBuilder.toString();}private boolean checkPermission(Context context, permission permName) {int perm = context.checkCallingOrSelfPermission('android.permission.' + permName.toString());return perm == PackageManager.PERMISSION_GRANTED;}private enum permission {ACCESS_COARSE_LOCATION,ACCESS_FINE_LOCATION}private String getLocationAddress(Context mContext, Location location) {String addNow = '';Geocoder geoCoder = new Geocoder(mContext, Locale.CHINESE);try {List<Address> addresses = geoCoder.getFromLocation(location.getLatitude(), location.getLongitude(),1);Address address = addresses.get(0);Log.w('wqs', '远程获取定位全部为: ' + address.toString());// Address[addressLines=[0:'中国',1:'北京市海淀区',2:'华奥饭店公司写字间中关村创业大街']latitude=39.980973,hasLongitude=true,longitude=116.301712]if (address.getAddressLine(0) != null && !address.getAddressLine(0).equals('')) {addNow = address.getAddressLine(0);Log.w('wqs', '获取成功第一种: ' + addNow);} else if (addNow.equals('') && address.getFeatureName() != null && !address.getFeatureName().equals('')) {addNow = address.getLocality() + address.getFeatureName();Log.w('wqs', '获取成功第二种: ' + addNow);} else {int maxLine = address.getMaxAddressLineIndex();if (maxLine >= 2) {addNow = address.getAddressLine(1) + address.getAddressLine(2);} else {addNow = address.getAddressLine(1);}Log.w('wqs', '获取成功第三种: ' + addNow);}} catch (IOException e) {addNow = '';e.printStackTrace();}if (addNow.contains('null')) {addNow = addNow.replaceAll('null', '');}return addNow;}/** * 判断GPS是否开启，GPS或者AGPS开启一个就认为是开启的 * * @param context * @return true 表示开启 */private boolean isOPenGPS(final Context context) {LocationManager locationManager= (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);// GPS定位boolean gps = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);// 网络服务定位boolean network = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);if (gps || network) {return true;}return false;}}
用法简单，直接调用即可LocationUtils.getInstance().getLocations(context);效果：
