This example explains how show how to get latitude, longitude values of an address.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it GecoderExample2.
2.) You will see some default code into your main.xml and android manifest file.
3.) Write following into main.xml file:

</LinearLayout>
4.) Run for output.
Steps:
1.) Create a project named GecoderExample2 and set the information as stated in the image.
Build Target: Android 2.1 (Google API)
Application Name: GecoderExample2
Package Name: com.example. Gecoder
Activity Name: Gecoder2Activity
Min SDK Version: 7
Application Name: GecoderExample2
Package Name: com.example. Gecoder
Activity Name: Gecoder2Activity
Min SDK Version: 7
2.) Open Gecoder2Activity.java file and write following code there:
package com.example.Geocoder;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
import java.io.IOException;
import java.util.List;

import android.widget.TextView;
import android.widget.Toast;
public class Gecoder2Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
destinationText = (EditText) findViewById(R.id.editbox);
Button cancelRecordButton = (Button) findViewById(R.id.Button);
cancelRecordButton.setOnClickListener(newOnClickListener() {
@Override
public void onClick(View v) {
checkAddress();
}
});
}
void checkAddress()
{
Geocoder geoCoder = new Geocoder(Gecoder2Activity.this,Locale.getDefault());
DestinationAddress =destinationText.getText().toString();
List<Address> addressList = null;
try {
addressList =geoCoder.getFromLocationName(DestinationAddress, 1);
} catch (IOException e) {
Toast.makeText(Gecoder2Activity.this,"Location not found!!! Please change address and try again.",Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
if(addressList.isEmpty())
{
AlertDialog.Builder dlgAlert = newAlertDialog.Builder(Gecoder2Activity.this);
dlgAlert.setMessage("Location not found!!! Please change address and try again.");
dlgAlert.setTitle("Gecoder2Activity");
dlgAlert.setPositiveButton("OK", null);
dlgAlert.setCancelable(true);
dlgAlert.create().show();
destinationText.requestFocus();
}
else
{
Address address = addressList.get(0);
if(address.hasLatitude() && address.hasLongitude()){
Toast.makeText(Gecoder2Activity.this,"Address : "+address.getAddressLine(0)+"\nCountry : "+address.getCountryName()+"\nLatitute : "+address.getLatitude()+"\nLongitute : "+address.getLongitude(),Toast.LENGTH_LONG).show();
}
}
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
destinationText = (EditText) findViewById(R.id.editbox);
Button cancelRecordButton = (Button) findViewById(R.id.Button);
cancelRecordButton.setOnClickListener(newOnClickListener() {
@Override
public void onClick(View v) {
checkAddress();
}
});
}
void checkAddress()
{
Geocoder geoCoder = new Geocoder(Gecoder2Activity.this,Locale.getDefault());
DestinationAddress =destinationText.getText().toString();
List<Address> addressList = null;
try {
addressList =geoCoder.getFromLocationName(DestinationAddress, 1);
} catch (IOException e) {
Toast.makeText(Gecoder2Activity.this,"Location not found!!! Please change address and try again.",Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
if(addressList.isEmpty())
{
AlertDialog.Builder dlgAlert = newAlertDialog.Builder(Gecoder2Activity.this);
dlgAlert.setMessage("Location not found!!! Please change address and try again.");
dlgAlert.setTitle("Gecoder2Activity");
dlgAlert.setPositiveButton("OK", null);
dlgAlert.setCancelable(true);
dlgAlert.create().show();
destinationText.requestFocus();
}
else
{
Address address = addressList.get(0);
if(address.hasLatitude() && address.hasLongitude()){
Toast.makeText(Gecoder2Activity.this,"Address : "+address.getAddressLine(0)+"\nCountry : "+address.getCountryName()+"\nLatitute : "+address.getLatitude()+"\nLongitute : "+address.getLongitude(),Toast.LENGTH_LONG).show();
}
}
}
}
3.) Compile and build the project for output.
Output
