HI Folks,
I am posting a ANDROID code for finding GPS latitude & longitude & offcourse with IMAGES it ll show you the addresses which you have specified.
Here are the steps for finding location Image of an GPS.
First create the main_activity class in your project.
--------------------------------------------------------------------------
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener{
EditText address;
EditText state;
EditText country;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.pre_main);
findViewById(R.id.get).setOnClickListener(this);
address = (EditText)findViewById(R.id.enterAddress);
state = (EditText)findViewById(R.id.enterState);
country = (EditText)findViewById(R.id.enterCountry);
}
public void onClick(View v)
{
String addressString = address.getText().toString().trim();
String stateString = state.getText().toString().trim();
String countryString = country.getText().toString().trim();
if(isValidAddress(addressString, stateString, countryString))
{
Intent i = new Intent(this, GPSActivity.class);
i.putExtra("address", addressString + " "+ stateString +" "+countryString);
startActivity(i);
}
else
{
Toast.makeText(getApplicationContext(), "Please provide valid address", Toast.LENGTH_LONG).show();
}
}
private boolean isValidAddress(String addressString, String stateString, String countryString)
{
if(addressString.length() < 1 && stateString.length() < 1 && countryString.length() < 1)
{
return false;
}
else
{
return true;
}
}
}
--------------------------------------------------------------------------
Create the main.XML file
--------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="center"
android:background="#ffffff">
<TextView
android:layout_width="fill_parent"
android:layout_height="70dp"
android:background="@drawable/map_icon"
android:layout_gravity="center"
android:padding="20dp"
android:textColor="#ffffff"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"/>
<EditText
android:id="@+id/enterAddress"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Enter address "
android:singleLine="true"
android:layout_margin="5dp"/>
<EditText
android:id="@+id/enterState"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Enter State "
android:singleLine="true"
android:layout_margin="5dp"/>
<EditText
android:id="@+id/enterCountry"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Enter Country"
android:singleLine="true"
android:layout_margin="5dp"/>
<Button
android:id="@+id/get"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Show Map"
android:layout_margin="5dp"/>
</LinearLayout>
--------------------------------------------------------------------------
for GPSActivity create WebView.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="fill_parent" >
<com.google.android.maps.MapView
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="00LAWIUYnasETyS-tTjYOv5v8KQz8vvmAEEsFQw"
android:clickable="true"
android:enabled="true" />
<LinearLayout
android:id="@+id/zoom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" />
</LinearLayout>
--------------------------------------------------------------------------
Now Create GPSActivity activity.

--------------------------------------------------------------------------
here is the android.manifest for GPS activity
--------------------------------------------------------------------------

</manifest>
--------------------------------------------------------------------------
don't forget to give INTERNET permission
--------------------------------------------------------------------------
Don't forget to upload com.google.android.maps.jar lib file which you will get from google map websites.
This project will not work on emulator sometimes . So better test it on device.
Hope this ll get help for some beginners in android.
