This example demonstrates how do I complete address from latitude and logitude in android.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<RelativeLayout xmlns:android="https://schemas.android.com/apk/res/android" xmlns:tools="https://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="16sp" tools:context=".MainActivity"> <TextView android:text="" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/textView" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="40dp" android:text="Show Address" android:id="@+id/btnShowAddress" android:layout_centerHorizontal="true" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/tvAddress" android:layout_alignParentBottom="true" android:layout_marginBottom="134dp" android:layout_alignParentEnd="true" /> </RelativeLayout>
Step 3 − Add the following code to src/MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.provider.Settings;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
Button btnShowAddress;
TextView tvAddress;
Location location;
AppLocationService appLocationService;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tvAddress = findViewById(R.id.tvAddress);
appLocationService = new
AppLocationService(MainActivity.this);
btnShowAddress = findViewById(R.id.btnShowAddress);
btnShowAddress.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
location = appLocationService.getLocation(LocationManager.GPS_PROVIDER);
double latitude = 13.1000727;
double longitude = 80.2126274;
LocationAddress locationAddress = new LocationAddress();
locationAddress.getAddressFromLocation(latitude, longitude,
getApplicationContext(), new GeoCodeHandler());
showSettingsAlert();
}
public void showSettingsAlert() {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
alertDialog.setTitle("SETTINGS");
alertDialog.setMessage("Enable Location
Provider! Go to settings menu?");
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
MainActivity.this.startActivity(intent);
}
});
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
alertDialog.show();
}
class GeoCodeHandler extends Handler {
@Override
public void handleMessage(Message message) {
String locationAddress;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
locationAddress = bundle.getString("address");
break;
default:
locationAddress = null;
}
tvAddress.setText(locationAddress);
}
}
});
}
}Step 4 − Create a java class (ApplicationService.java) and add the following code
import android.annotation.SuppressLint;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
@SuppressLint("Registered")
public class AppLocationService extends Service implements LocationListener {
protected LocationManager locationManager;
Location location;
private static final long MIN_DISTANCE_FOR_UPDATE = 10;
private static final long MIN_TIME_FOR_UPDATE = 1000 * 60 * 2;
public AppLocationService(Context context) {
locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
}
@SuppressLint("MissingPermission")
public Location getLocation(String provider) {
if (locationManager.isProviderEnabled(provider)) {
locationManager.requestLocationUpdates(provider,
MIN_TIME_FOR_UPDATE,
MIN_DISTANCE_FOR_UPDATE, this);
if (locationManager != null) {
location = locationManager.getLastKnownLocation(provider);
return location;
}
}
return null;
}
@Override
public void onLocationChanged(Location location) {
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
}Step 5 − Create a java class (LocationAddress.java) and add the following code −
import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
class LocationAddress {
private static final String TAG = "LocationAddress";
static void getAddressFromLocation(final double latitude,
final double longitude, final Context context, final Handler
handler) {
Thread thread = new Thread() {
@Override
public void run() {
Geocoder geocoder = new Geocoder(context,
Locale.getDefault());
String result = null;
try {
List<Address> addressList =
geocoder.getFromLocation(
latitude, longitude, 1);
if (addressList != null &&
addressList.size() > 0) {
Address address = addressList.get(0);
StringBuilder sb = new
StringBuilder();
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
sb.append(address.getAddressLine(i)).append("\n");
}
sb.append(address.getLocality()).append("\n");
sb.append(address.getPostalCode()).append("\n");
sb.append(address.getCountryName());
result = sb.toString();
}
} catch (IOException e) {
Log.e(TAG, "Unable connect to Geocoder", e);
} finally {
Message message = Message.obtain();
message.setTarget(handler);
if (result != null) {
message.what = 1;
Bundle bundle = new Bundle();
result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n\nAddress:\n" + result;
bundle.putString("address", result);
message.setData(bundle);
} else {
message.what = 1;
Bundle bundle = new Bundle();
result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n Unable to get address for
this lat-long.";
bundle.putString("address" , result);
message.setData(bundle);
}
message.sendToTarget();
}
}
};
thread.start();
}
}Step 6 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="https://schemas.android.com/apk/res/android" package="app.com.sample"> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
