如何从纬度和经度获得完整的地址?

I want to get following values from Latitude and Longitude in android

我想在android中从纬度和经度获取以下值

1. Street Address
2. 街道地址
3. City / State
4. 城市/州
5. Zip
6. 邮政编码
7. Complete Address
8. 完整的地址

How to achieve this?

如何实现呢?

Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());

addresses = geocoder.getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5

String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL

Try this My friend

试试我的朋友

 private String getCompleteAddressString(double LATITUDE, double LONGITUDE) {
            String strAdd = "";
            Geocoder geocoder = new Geocoder(this, Locale.getDefault());
            try {
                List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
                if (addresses != null) {
                    Address returnedAddress = addresses.get(0);
                    StringBuilder strReturnedAddress = new StringBuilder("");

                    for (int i = 0; i <= returnedAddress.getMaxAddressLineIndex(); i++) {
                        strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
                    }
                    strAdd = strReturnedAddress.toString();
                    Log.w("My Current loction address", strReturnedAddress.toString());
                } else {
                    Log.w("My Current loction address", "No Address returned!");
                }
            } catch (Exception e) {
                e.printStackTrace();
                Log.w("My Current loction address", "Canont get Address!");
            }
            return strAdd;
        }

There is a last trick to get Address from Lat-Long (Geo-coordinates). You can simply hit google-maps web service passing the Latitude and longitude. It is simply a GET-Method web-service.

还有最后一个技巧可以从latlong(地理坐标)获取地址。只需点击google-maps web服务，即可通过纬度和经度。它只是一个GET-Method web服务。

It will return the JSON Response that can be parsed easily to get address. The URL for this is:

它将返回可以轻松解析的JSON响应以获取地址。其URL为:

http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true

You can replace 32,75 with lat,long.

你可以用lat,long来替换32 75。

#4

City & Country are not Always getting in address Line 1 & Line 2...

城市和国家并不总是在地址线1和线2…

Example is here

这里的例子是

So,

所以,

Geocoder geocoder = new Geocoder(context, Locale.getDefault());

List<Address> addresses  = geocoder.getFromLocation(latitude,longitude, 1);

String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String zip = addresses.get(0).getPostalCode();
String country = addresses.get(0).getCountryName();

#5

In onCreate()..

在onCreate(). .

LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, this);




    Criteria criteria = new Criteria();
    String bestProvider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(bestProvider);

    if (location == null) {
        Toast.makeText(getApplicationContext(), "GPS signal not found",
                3000).show();
    }
    if (location != null) {
        Log.e("locatin", "location--" + location);

        Log.e("latitude at beginning",
                "@@@@@@@@@@@@@@@" + location.getLatitude());
        onLocationChanged(location);
    }

Write the code in onLocationChanged()

在onLocationChanged()中编写代码

@Override
public void onLocationChanged(Location location) {

    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(this, Locale.getDefault());

    latitude = location.getLatitude();
    longitude = location.getLongitude();

    Log.e("latitude", "latitude--" + latitude);

    try {
        Log.e("latitude", "inside latitude--" + latitude);
        addresses = geocoder.getFromLocation(latitude, longitude, 1);





        if (addresses != null && addresses.size() > 0) {
            String address = addresses.get(0).getAddressLine(0); 
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName(); 

            locationTxt.setText(address + " " + city + " " + country);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

You are looking for the term Geocoding.

您正在寻找术语地理编码。

The short story is you need to do:

短篇故事是你需要做的:

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);

To do more you should read up on the Geocoder here.

要做得更多，您应该在这里阅读Geocoder。

Just Use this method and pass your lat, long.

就用这个方法，把你的腰传过去。

public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {

    //Set Address
    try {
        Geocoder geocoder = new Geocoder(context, Locale.getDefault());
        List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
        if (addresses != null && addresses.size() > 0) {



            String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
            String city = addresses.get(0).getLocality();
            String state = addresses.get(0).getAdminArea();
            String country = addresses.get(0).getCountryName();
            String postalCode = addresses.get(0).getPostalCode();
            String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL

            Log.d(TAG, "getAddress:  address" + address);
            Log.d(TAG, "getAddress:  city" + city);
            Log.d(TAG, "getAddress:  state" + state);
            Log.d(TAG, "getAddress:  postalCode" + postalCode);
            Log.d(TAG, "getAddress:  knownName" + knownName);

        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return;
}

You Can use this method for geocoding proper complete Address

#15

1 - You create variables for LocationManager and LocationListener in onCreate method.

1 -在onCreate方法中为LocationManager和LocationListener创建变量。

2 - Check if there is a permission so execute the location updates and get lastKnownLocation from locationManager else you ask for permission

2 -检查是否有权限，因此执行位置更新并从locationManager获取lastKnownLocation否则你会请求权限

3 - Create onRequestPermissionResult in main class and check if there is a permission then execute the location updates

3 -在主类中创建onRequestPermissionResult，并检查是否有权限执行位置更新。

4 - Create separated method which includes Geocoder variable and create a list to put the coordinates from your location, so to be safe you check if the List is exist and if each info we want in that list is exist, then you use (getThoroughfare ==> for Street Address), (getLocality ==> for City / State), (getPostalCode ==> for Zip), (getAdminArea ==> for Complete Address)

4 -创建分离方法包括Geocoder变量和创建一个列表将从你的位置坐标,所以为了安全起见你检查列表中是否存在,如果每一个我们想要的信息在列表是存在的,然后使用街道地址(getThoroughfare = = >),(城市/州getLocality = = >),(Zip getPostalCode = = >),(getAdminArea = = >完整地址)

5 - Finally you call that method after checking the permission with (lastKnownLocation parameter ==> to show address when the App runs) and in onLocationChanged with (location parameter ==> to show address when location changes)

5 -最后，在检查权限(lastKnownLocation参数=>显示App运行时的地址)和onLocationChanged with (location参数=>显示位置改变时的地址)后调用该方法

It seems that no-one has yet provided the solution suggested by Google Docs (https://developer.android.com/training/location/display-address#java). The correct solution should use an IntentService to make the network call for reverse geocoding.

似乎还没有人提供谷歌文档建议的解决方案(https://developer.android.com/training/location/display-address#java)。正确的解决方案应该使用IntentService进行反向地理编码的网络调用。

An intent service is used rather than an AsyncTask as it is not tied to any specific activity. ie. it has its own lifecycle. The IntentService will stop itself when the Geocoding is finished.

使用意图服务而不是AsyncTask，因为它没有绑定到任何特定的活动。ie。它有自己的生命周期。当地理编码完成时，IntentService将自动停止。

public class GeocodingService extends IntentService {

    public GeocodingService() {
        super("GeocodingService");
    }


    @Override
    protected void onHandleIntent(@Nullable Intent intent) {

                "location");
