Step 1

   Copy pate following code in main.xml

 

 <?xml version="1.0" encoding="UTF-8"?>

       <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:layout_width="fill_parent"

              android:layout_height="wrap_content" android:layout_alignParentBottom="true"

              <TextView android:id="@+id/position" android:layout_width="fill_parent"

                     android:layout_height="wrap_content"  />

       </LinearLayout>

Step 2

  Copy paste following Code in your Main Activity Class...

  In here your package name and your Main Activity Class name is different from my code ......

package com.adrianfindaddress;

import java.util.List;

import com.google.android.maps.GeoPoint;

import android.location.Address; 

import android.location.Geocoder; 

import android.os.Bundle; 

import android.view.View; 

import android.view.View.OnClickListener; 

import android.widget.Button; 

import android.widget.EditText; 

import android.widget.TextView; 

 

import com.google.android.maps.GeoPoint; 

import com.google.android.maps.MapActivity; 

import com.google.android.maps.MapView;

public class AdrianLocationFinderActivity extends MapActivity {

    /** Called when the activity is first created. */

        Geocoder geocoder = null; 

        

           @Override 

           protected void onCreate(Bundle savedInstanceState) { 

               super.onCreate(savedInstanceState); 

               setContentView(R.layout.main); 

       

            

               Button geoBtn = (Button) findViewById(R.id.geocodeBtn); 

        

               geocoder = new Geocoder(this); 

        

               geoBtn.setOnClickListener(new OnClickListener() { 

        

                   @Override 

                   public void onClick(View v) { 

                       try { 

                           EditText locale = (EditText) findViewById(R.id.location); 

                           String locationName = locale.getText().toString(); 

        

                           List<Address> addressList = geocoder.getFromLocationName( 

                                   locationName, 5); 

                           if (addressList != null && addressList.size() > 0) { 

                               int lat = (int) (addressList.get(0).getLatitude() * 1e6); 

                               int lng = (int) (addressList.get(0).getLongitude() * 1e6); 

        

                               TextView displayLocation= (TextView) findViewById(R.id.position); 

                               displayLocation.setText("lat: " 

                                       + addressList.get(0).getLatitude() + " lng: " 

                                       + addressList.get(0).getLongitude()); 

        

                              

                           

                           } 

                       } catch (Exception e) { 

                           e.printStackTrace(); 

                       } 

                   } 

               }); 

           } 

        

           @Override 

           public boolean isLocationDisplayed() { 

               return false; 

           } 

        

           @Override 

           public boolean isRouteDisplayed() { 

               return false; 

           } 

       } 

 

Step 3

   AndroidManifest.xml  ... Add user permission

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.adrianfindaddress"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="4" />

   

     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

 

    <application

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name" >

       

           <uses-library android:name="com.google.android.maps" />

       

       

        <activity

            android:name=".AdrianLocationFinderActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

Step 4

Now Run the App....
