Android:how to get lat and long into my adapter

Android:how to get lat and long into my adapter - android

I want to get latitude and longitude of a place when i enter my address. i have one activity with programatically created custom dailog, this has the address feilds, when i type my address i need to get the latitude and logitude. below is my adapter code where i am trying to get the lat and lng details
public void performAction(View v, final Activity activity) {
Context myContext = v.getContext();
PopUpMenu popUpMenu = (PopUpMenu) v.getTag();
String result = popUpMenu.getMenuName();
if (result != null
&& result.equalsIgnoreCase(myContext.getResources().getString(
R.string.addnewplace))) {
AttractionData attractionData = new AttractionData();
createDiloag(attractionData,activity.getResources().getString(R.string.addnewplace));
setgpsLocation();
}
public void setgpsLocation() {
final EditText address = new EditText(this.activity);
String addressText = address.getText().toString();
try {
final StringBuffer myAddress = new StringBuffer();
if(addressText!=null&&!addressText.trim().equals("")){
myAddress.append(addressText);
}
Geocoder gcd = new Geocoder(parentActivity, Locale.getDefault());
List<Address> addresses = gcd.getFromLocationName(addressText, 5);
if (addressList != null && addressList.size() > 0) {
Address location = addressList.get(0);
location.getLatitude();
location.getLongitude();
// int lat = (int) (addressList.get(0).getLatitude() * 1e6);
// int lng = (int) (addressList.get(0).getLongitude() * 1e6);
AttractionData attractionData = new AttractionData();
attractionData.setLatitude(location.getLatitude());
attractionData.setLongitude( location.getLongitude());
} catch (Exception e) {
Log.e(TAG, "Error", e);
}
}
I am unable to get the lat lng details, Any help is appreciated.

I believe the problem is with the following lines:
final EditText address = new EditText(this.activity);
String addressText = address.getText().toString();
You addressText will be an empty string every time because you're creating a new EditText instead of using the one from the existing activity.
Try to replace it with:
final EditText address = (EditText)this.activity.findViewById(R.id.your_edit_text_id);
and replace your_edit_text_id with the id in your layout file.
If you created your view programmatically then provide a getter for it.
In your activity:
public EditText getAddressEditText() {
return this.mAddressEditText;
}
And then use it like this:
final EditText address = this.activity.getAddressEditText();

Try
Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = gcd.getFromLocation(lat, lng, 1);
} catch (IOException e) {
e.printStackTrace();
}
if (addresses != null && addresses.size() > 0) {
String locality = addresses.get(0).getLocality();
}

Use below code to get city name
Geocoder geocoder = new Geocoder(this);
try {
List<Address>addresses = geocoder.getFromLocation(latitude,longitue,1);
if (geocoder.isPresent()) {
StringBuilder stringBuilder = new StringBuilder();
if (addresses.size()>0) {
Address returnAddress = addresses.get(0);
String localityString = returnAddress.getLocality();
String name = returnAddress.getFeatureName();
String subLocality = returnAddress.getSubLocality();
String country = returnAddress.getCountryName();
String region_code = returnAddress.getCountryCode();
String zipcode = returnAddress.getPostalCode();
String state = returnAddress.getAdminArea();
}
} else {
}
} catch (IOException e) {
e.printStackTrace();
}

Try this code, Hope it helps..
private static String getRegionName(double lati, double longi) {
String regioName = "";
Geocoder gcd = new Geocoder(AppInstance, Locale.getDefault());
try {
List<Address> addresses = gcd.getFromLocation(lati, longi, 1);
if (addresses.size() > 0) {
regioName = addresses.get(0).getLocality();
}
} catch (Exception e) {
e.printStackTrace();
}
return regioName;
}

Try to use following code to get complete address,
//Get address from Google api
//Log.e("Else","else");
try {
JSONObject jsonObj = getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + latitude + ","
+ longitude + "&sensor=true");
String Status = jsonObj.getString("status");
if (Status.equalsIgnoreCase("OK")) {
JSONArray Results = jsonObj.getJSONArray("results");
JSONObject location = Results.getJSONObject(0);
finalAddress = location.getString("formatted_address");
}
} catch (Exception e) {
e.printStackTrace();
}
instead of,
geocoder.getFromLocation(latitude, longitude, 1);

For Avoid ArrayIndexOutOfBound you could add if condition like below:
if (addresses != null && addresses.size() > 0) {
String locality = addresses.get(0).getLocality();
}
but, as I saw your code you are trying to get address using GeoCoder inside button click, So avoid this because it is a network call. You should not perform network call in main thread, it could block UI Or Cause ANR. You should use AsyncTask/Thread for network operation to avoid blocking Of UI.
Also make sure you have added
INTERNET_PERMISSION
in your manifest file.
Hope It help you !

Error states that the Array list is empty so make sure you initialize the list and check if it contains any data.
try this code:
List<Address> addresses = new List<Address>;
addresses = geocoder.getFromLocation(latitude, longitude, 1);

if(addresses != null) {
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();
}
This should give you required info.

my findViewByID is thowing error?

My findViewById is throwing error saying it has not been defined and it asks me to create a function. What should I do?
public void geoLocate(View v) throws IOException {
hideSoftKeyboard(v);
EditText et = (EditText) findViewById(R.id.editText1);
String location = et.getText().toString();
Geocoder gc = new Geocoder(context);
List<Address> list = gc.getFromLocationName(location, 1);
Address add = list.get(0);
String locality = add.getLocality();
Toast.makeText(context, locality, Toast.LENGTH_LONG).show();
double lat = add.getLatitude();
double lng = add.getLatitude();
gotoLocation(lat, lng, DEFAULTZOOM);
MarkerOptions markerOptions = new MarkerOptions().title(locality).position(new LatLng(lat,lng));
mMap.addMarker(markerOptions);
}

In your function find id like this
EditText et = (EditText) v.findViewById(R.id.editText1);
You havve to use the View variable passed in the method to find id

getLastKnownLocation can't get new data by location.setLatitude/setLongitude?

My full code
https://gist.github.com/anonymous/6dd0f33270cc4f46149e
In line 110~131 I want to change the location, it does work, the mapview will change
private class MapClickedListener implements OnClickListener {
#Override
public void onClick (View v) {
String lng = "121.558561";
lng = edt_lng.getText().toString().trim();
String lat = "25.031005";
lat = edt_lat.getText().toString().trim();
if(lng.equals("")||lat.equals("")){
Toast.makeText(getApplicationContext(), "input again！", Toast.LENGTH_LONG).show();
location = locManager.getLastKnownLocation(bestProvider);
updateToNewLocation(location);
}else{
Location location = new Location(LocationManager.NETWORK_PROVIDER);
location.setLongitude(Double.parseDouble(lng));
location.setLatitude(Double.parseDouble(lat));
updateToNewLocation(location);
}
}
}
On line 133~148, I want to know distance between location and a point I set
private Button.OnClickListener EQ = new Button.OnClickListener(){
#Override
public void onClick (View v) {
eqlocation.setLongitude(120.82);
eqlocation.setLatitude(23.85);
location = locManager.getLastKnownLocation(bestProvider);
float[] result = new float[5];
Location.distanceBetween(location.getLatitude(), location.getLongitude(), eqlocation.getLatitude(), eqlocation.getLongitude(), result);
BigDecimal bd = new BigDecimal(result[0]);
BigDecimal rounded = bd.setScale(2, RoundingMode.HALF_UP);
double dis = rounded.doubleValue();
String dist = String.valueOf(dis/1000);
Toast.makeText(getApplicationContext(), "distance： " + dist + "km", Toast.LENGTH_LONG).show();
}
};
But the result is wrong when I change the location by line 110~131's code.
What should I do to get the right result?

have you tried distanceTo() and checked if you get any better results?, I ususally use distanceTo() with good results.

How to get the address by latitude and longitude using openstreetmap in android

In my app I am using osm map. I have latitude and longitude.
using this method
proj = mapView.getProjection();
loc = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY());
String longitude = Double
.toString(((double) loc.getLongitudeE6()) / 1000000);
String latitude = Double
.toString(((double) loc.getLatitudeE6()) / 1000000);
Toast toast = Toast.makeText(getApplicationContext(), "Longitude: "
+ longitude + " Latitude: " + latitude, Toast.LENGTH_SHORT);
toast.show();
So from here how I will query to get the city name from osm database. Please help me.
How can I convert this into human understandable form. Here is my code which I am using.link

Try this code for getting address.
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
addresses = geocoder.getFromLocation(latitude, longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getAddressLine(1);
String country = addresses.get(0).getAddressLine(2);
for openstreammap
final String requestString = "http://nominatim.openstreetmap.org/reverse?format=json&lat=" +
Double.toString(lat) + "&lon=" + Double.toString(lon) + "&zoom=18&addressdetails=1";
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL.encode(requestString));
try {
#SuppressWarnings("unused")
Request request = builder.sendRequest(null, new RequestCallback() {
#Override
public void onResponseReceived(Request request, Response response) {
if (response.getStatusCode() == 200) {
String city = "";
try {
JSONValue json = JSONParser.parseStrict(response);
JSONObject address = json.isObject().get("address").isObject();
final String quotes = "^\"|\"$";
if (address.get("city") != null) {
city = address.get("city").toString().replaceAll(quotes, "");
} else if (address.get("village") != null) {
city = address.get("village").toString().replaceAll(quotes, "");
}
} catch (Exception e) {
}
}
}
});
} catch (Exception e) {
}

here is my solution. i think it works for you also.
public String ConvertPointToLocation(GeoPoint point) {
String address = "";
Geocoder geoCoder = new Geocoder( getBaseContext(), Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(
point.getLatitudeE6() / 1E6,
point.getLongitudeE6() / 1E6, 1);
if (addresses.size() > 0) {
for (int index = 0; index < addresses.get(0).getMaxAddressLineIndex(); index++)
address += addresses.get(0).getAddressLine(index) + " ";
}
Toast.makeText(getBaseContext(), address, Toast.LENGTH_SHORT).show();
}
catch (IOException e) {
e.printStackTrace();
}
return address;
}

GoogleMaps on Android using Google API 2.3.3 Level 10, finding by address

Im trying to display the address from an EditText using geoCoder and also it would be able editable to click on the finder button and update the googlemap display on the top of the screen, this is my code:
Geocoder geocoder = null;
MapView mapView = null;
int lat, lng;
EditText loc;
#Override
protected boolean isRouteDisplayed() {
return false;
}
#Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.geoMap);
try
{
loc = (EditText)findViewById(R.id.location);
String locationName = loc.getText().toString();
List<Address> addressList = geocoder.getFromLocationName(locationName, 5);
if (addressList != null && addressList.size() > 0) {
lat = (int) addressList.get(0).getLatitude() * 1000000;
lng = (int) addressList.get(0).getLongitude() * 1000000;
GeoPoint pt = new GeoPoint(lat, lng);
mapView.getController().setZoom(10);
mapView.getController().setCenter(pt);
mapView.getController().animateTo(pt);
}
}
catch
(IOException e)
{
e.printStackTrace();
}
//
Button geoBtn = (Button) findViewById(R.id.geocodeBtn);
geocoder = new Geocoder(this);
//
geoBtn.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
try {
EditText loc = (EditText) findViewById(R.id.location);
String locationName = loc.getText().toString();
List<Address> addressList = geocoder.getFromLocationName(locationName, 5);
if (addressList != null && addressList.size() > 0) {
int lat = (int) addressList.get(0).getLatitude() * 1000000;
int lng = (int) addressList.get(0).getLongitude() * 1000000;
GeoPoint pt = new GeoPoint(lat, lng);
mapView.getController().setZoom(10);
mapView.getController().setCenter(pt);
mapView.getController().animateTo(pt);
}
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
But it crashes at this point: List addressList = geocoder.getFromLocationName(locationName, 5);
Im using googles APi 2.3.3.
