只要用这个方法,把你的背,长。
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;
}
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("location", "location--" + location);
Log.e("latitude at beginning",
"@@@@@@@@@@@@@@@" + location.getLatitude());
onLocationChanged(location);
}
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();
}
}
接受的答案在kotlin格式
private fun getAddressInfo(latitude:Double, longitude:Double){
val geocoder = Geocoder(this, Locale.getDefault())
val addresses: List<Address> = geocoder.getFromLocation(latitude, longitude, 1)
val address: String = addresses[0].getAddressLine(0)
val city: String = addresses[0].locality
val state: String = addresses[0].adminArea
val country: String = addresses[0].countryName
val postalCode: String = addresses[0].postalCode
val knownName: String = addresses[0].featureName
}
1 -在onCreate方法中为LocationManager和LocationListener创建变量。
2 -检查是否有权限,因此执行位置更新并从locationManager获取lastKnownLocation,否则您将请求权限
3 -在主类中创建onRequestPermissionResult并检查是否有权限,然后执行位置更新
4 -创建分离的方法,其中包括Geocoder变量,并创建一个列表,从您的位置放置坐标, 所以为了安全起见,你检查列表是否存在,如果我们想在该列表中的每个信息是存在的,那么你使用(get通道==>街道地址),(getLocality ==>城市/州),(getPostalCode ==> Zip), (getAdminArea ==>完整地址)
5 -最后,在检查权限后调用该方法(lastKnownLocation参数==>,当应用程序运行时显示地址)和onLocationChanged with(位置参数==>,当位置改变时显示地址)
代码部分:
LocationManager locationManager;
LocationListener locationListener;
@SuppressLint("MissingPermission")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
updateLocation(location);
}
@Override public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
};
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED){
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
Location lastKnownLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
updateLocation(lastKnownLocation);
}else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

}
}
}
public void updateLocation ( Location location){
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
try {
List<Address> listAddresses = geocoder.getFromLocation(location.getLatitude(),location.getLongitude(),1);
String address = "Could not find location :(";
if (listAddresses != null && listAddresses.size() > 0) {
if (listAddresses.get(0).getThoroughfare() != null) {

}
if (listAddresses.get(0).getLocality() != null) {
address += listAddresses.get(0).getLocality() + " ";
}
if (listAddresses.get(0).getPostalCode() != null) {
address += listAddresses.get(0).getPostalCode() + " ";
}
if (listAddresses.get(0).getAdminArea() != null) {
address += listAddresses.get(0).getAdminArea();
}
}
Log.i("Address",address);
} catch (Exception e) {
e.printStackTrace();
}
}
}
你可以创建类
public class GeoLocation {
private Context mContext;
private String mLatitude;
private String mLongtitude;
private String mStreet;
private String mHouseNumber;
private String mPostalCode;
private String mCity;
private Location mMarkerLocation;
public GeoLocation (Context context) {
mContext = context;
}
public String getStreet () {
return mStreet;
}
public String getHouseNumber () {
return mHouseNumber;
}
public String getPostalCode () {
return mPostalCode;
}
public String getCity () {
return mCity;
}
public String getLatitude () {
return mLatitude;
}
public String getLongtitude () {
return mLongtitude;
}
// Lookup address via reverse geolocation
// Call this one
public void lookUpAddress (Location markerLocation) {
mMarkerLocation = markerLocation;
if (Geocoder.isPresent()) {
(new GetAddressTask(mContext)).execute();
}
}
public class GetAddressTask extends AsyncTask<android.location.Location, Void, String> {
public GetAddressTask (Context context) {
super();
mContext = context;
}
@Override
protected String doInBackground (android.location.Location... params) {
Geocoder geocoder =
new Geocoder(mContext, Locale.getDefault());
android.location.Location location = params[0];
List<Address> addresses = null;
try {
if (mMarkerLocation != null) {
addresses = geocoder.getFromLocation(mMarkerLocation.getLatitude(),
mMarkerLocation.getLongitude(), 1);
}
} catch (IOException exception) {
Log.e("ComplaintLocation",
"IO Exception in getFromLocation()", exception);
return ("IO Exception trying to get address");
} catch (IllegalArgumentException exception) {
String errorString = "Illegal arguments " +
Double.toString(location.getLatitude()) + " , " +
Double.toString(location.getLongitude()) + " passed to address service";
Log.e("LocationSampleActivity", errorString, exception);
return errorString;
}
if (addresses != null && addresses.size() > 0) {
Address address = addresses.get(0);
if (address.getMaxAddressLineIndex() > 0) {
return String.format(
"%s/%s/%s/%s/%s/%s",
address.getLatitude(), // 0
address.getLongitude(), // 1
address.getThoroughfare(), // 2
address.getSubThoroughfare(), //3
address.getPostalCode(), // 4
address.getLocality()); // 5
} else {
return String.format(
"%s/%s/%s/%s",
address.getLatitude(), // 0
address.getLongitude(), // 1
address.getPostalCode(), // 2
address.getLocality()); // 3
}
} else return "No address found";
}
// Format address string after lookup
@Override
protected void onPostExecute (String address) {
String[] addressFields = TextUtils.split(address, "/");
Log.d("ADDRESS ARRAY", Arrays.toString(addressFields));
// Workaround: doInBackground can only return Strings instead of, for example, an
// Address instance or a String[] directly. To be able to use TextUtils.isEmpty()
// on fields returned by this method, set each String that currently reads "null" to
// a null reference
for (int fieldcnt = 0; fieldcnt < addressFields.length; ++fieldcnt) {
if (addressFields[fieldcnt].equals("null"))
addressFields[fieldcnt] = null;
}
switch (addressFields.length) {
case 4:
mStreet = null;
mHouseNumber = null;
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mPostalCode = addressFields[2];
mCity = addressFields[3];
break;
case 6:
mLatitude = addressFields[0];
mLongtitude = addressFields[1];
mStreet = addressFields[2];
mHouseNumber = addressFields[3];
mPostalCode = addressFields[4];
mCity = addressFields[5];
break;
default:
mLatitude = null;
mLongtitude = null;
mStreet = null;
mHouseNumber = null;
mPostalCode = null;
mCity = null;
break;
}
Log.d("GeoLocation Street", mStreet);
Log.d("GeoLocation No.", mHouseNumber);
Log.d("GeoLocation Postalcode", mPostalCode);
Log.d("GeoLocation Locality", mCity);
Log.d("GeoLocation Lat/Lng", "[" + mLatitude + ", " + mLongtitude +
"]");
}
}
}
然后使用
GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);
