Android 获取位置信息(经纬度以及坐标)

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

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* 位置提供器、监听位置变化的时间间隔(毫秒),监听位置变化的距离间隔(米),LocationListener监听器*/// locationManager.requestLocationUpdates(provider, 0, 0, locationListener);// new Handler().postDelayed(new Runnable() {//@Override//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(WORK_PROVIDER);if (gps || network) {return true;}return false;}}
