I have displayed the map in my app by using the following code. I have retrieved info from the database and displayed the map. Now i want to add marker to the retrieved location...

googleMao.java

public class googleMap extends MapActivity{ private MapView mapView; private MapController mc; GeoPoint p; long s; Cursor cur; SQLiteDatabase db; createSqliteHelper csh; String qurry; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.map); // String qurry=getIntent().getStringExtra("value"); //here is calling the map string qurry s = getIntent().getLongExtra("value",2); map(); mapView = (MapView) findViewById(R.id.mapview1);
LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);
View zoomView = mapView.getZoomControls();

        zoomLayout.addView(zoomView, 
            new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT)); 
        //mapView.displayZoomControls(true);
       mapView.setBuiltInZoomControls(true);
        mc = mapView.getController();
        String coordinates[] = {"1.352566007", "103.78921587"};
        double lat = Double.parseDouble(coordinates[0]);
        double lng = Double.parseDouble(coordinates[1]);

        Geocoder geoCoder = new Geocoder(this, Locale.getDefault());    
        try {
            List<Address> addresses = geoCoder.getFromLocationName(qurry,5);
            String add = "";
            if (addresses.size() > 0) {
                p = new GeoPoint(
                        (int) (addresses.get(0).getLatitude() * 1E6), 
                        (int) (addresses.get(0).getLongitude() * 1E6));
                mc.animateTo(p);    
                mapView.invalidate();
                mc.setZoom(6);
            }    
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

   @Override
   protected boolean isRouteDisplayed() {
      // Required by MapActivity
      return false;
   }
   public void map()
   {
       String[] str={"type"};
       int[] i={R.id.type};
       csh=new createSqliteHelper(this);
       db=csh.getReadableDatabase();
       cur=db.rawQuery("select type from restaurants where _id="+s,null);
       if(cur.moveToFirst())
       {
          qurry=cur.getString(cur.getColumnIndex("type"));
       }
   }

}
