Google Map Location Example in Andriod:By VKHooda: July 2011

Hi,This is simple source code to find out the location without using geocoading in android.When user want to find out any location in google map,use this source code to make helpful for urself.
Here,I am making two class but you can do it only single one.
<b>mapfinder.class</b>

        inputStream.close();



       // text.setText(stringBuilder.toString());
       }
    } catch (ClientProtocolException e) {

        me=new MyLocationOverlay(this, map);
        map.getOverlays().add(me);
    }

                    (Double.parseDouble(v.elementAt(2).toString()),Double.parseDouble(v.elementAt(3).toString())),
                                "UN", "United Nations"));

            populate();
        }

        @Override
        protected OverlayItem createItem(int i) {
            return(items.get(i));
        }

        @Override
        public void draw(Canvas canvas, MapView mapView,
                                        boolean shadow) {

            boundCenterBottom(marker);
        }

        @Override
        protected boolean onTap(int i) {
            Toast.makeText(mapfinder.this,
                                items.get(i).getSnippet(),
                                Toast.LENGTH_SHORT).show();

            return(true);
        }

        @Override
        public int size() {
            return(items.size());
        }
    }
}
locationlocator.class: This is second class

import java.util.Vector;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

import com.google.android.maps.MapView;
import com.google.android.maps.MyLocationOverlay;

public class locationlocator extends Activity implements OnClickListener {
//    @Override
//    protected boolean isRouteDisplayed() {
//        return false;
// }

    final String httpPath = "addressInput";
    private MapView map;
    private Button btnSearch;
    public static EditText addressInput;
    private ProgressDialog pd;
    private Vector<String> v1;
    private MyLocationOverlay me=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    //    map = (MapView) findViewById(R.id.mapview); // Get map from XML
        btnSearch = (Button) findViewById(R.id.simplebtn_search); // Get button from xml
        addressInput = (EditText) findViewById(R.id.simpleadress);
        btnSearch.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {

        startActivity( new Intent(locationlocator.this,mapfinder.class));
    }


}
After making this class. u can also add XML file for both of class.Also remember to add permission in manifest file.
May b this code helpful for you.
Wait for next blog.
