when pin touch then how to open map balloon (annotation) for more information in android

I make small static map application, in which i take three pin(marker) and set static longitude and latitude. Actually, i want to display balloon annotation for location information display in mapview. when i touch the marker(pin) then balloon annotation is open and display the information for current location. My code is following:

Hello, MapView! tutorial covers showing markers on MapView. In the tutorial markers are added as soon as the activity starts, but you can also add markers at later time, for example, when user touches screen. If you try this approach, you'll likely want to override onTap in your subclass of ItemizedOverlay.
Update:
If you follow the tutorial, you'll have your own subclass of ItemizedOverlay. onTap is one of its methods. Now that I look at the documentation, unfortunately onTap(GeoPoint p, MapView mapView) is not public or protected so you cannot override it.
What you can do, is have another overlay, solely for detecting taps. Instead of subclassing ItemizedOverlay, subclass Overlay.
private class TapOverlay extends Overlay {
public boolean onTap(GeoPoint p, MapView mapView) {
// code that adds item in your ItemizedOverlay
// goes here
return true;
}
}

Mark name of location on map?

In my Android app I want to mark on map a location (I know the address of location). When I mark it on map, I want to display the name of location,too. How can I do that?
I have this: OverlayItem(p ,"Kaufland", "Magic Kingdom"),but on map appear only the point,without the name.
Here is my code:

import android.location.Address;

public class ShowMap extends MapActivity {

MapController mc;

super.onCreate(savedInstanceState);
setContentView(R.layout.showmap);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setClickable(true);
Drawable marker=getResources().getDrawable(R.drawable.pushpin);
marker.setBounds(0, 0, marker.getIntrinsicWidth(),
marker.getIntrinsicHeight());
InterestingLocations funPlaces = new InterestingLocations(marker);
mapView.getOverlays().add(funPlaces);
GeoPoint pt = funPlaces.getCenter(); // get the first-ranked point
mapView.getController().setCenter(pt);
mapView.getController().setZoom(15);
}
#Override
protected boolean isLocationDisplayed() {
return false;
}
#Override
protected boolean isRouteDisplayed() {
return false;
}
class InterestingLocations extends ItemizedOverlay {
private List locations = new ArrayList();
private Drawable marker;
String adresa;
public InterestingLocations(Drawable marker)
{
super(marker);
this.marker=marker;
// create locations of interest
Bundle bundle = getIntent().getExtras();
adresa = bundle.getString("adress");
Geocoder geoCoder = new Geocoder(ShowMap.this, Locale.getDefault());
try {
List addresses = geoCoder.getFromLocationName(adresa, 5);
String add = "";
if (addresses.size() > 0) {
GeoPoint p = new GeoPoint((int) (addresses.get(0).getLatitude() * 1E6),
(int) (addresses.get(0).getLongitude() * 1E6));
locations.add(new OverlayItem(p ,"Kaufland", "Magic Kingdom"));
}
} catch (IOException e) {
e.printStackTrace();
}
populate();
}
#Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {
super.draw(canvas, mapView, shadow);
boundCenterBottom(marker);
}
#Override
protected OverlayItem createItem(int i) {
return locations.get(i);
}
#Override
public int size() {
return locations.size();
}
}
}

I can't believe there's no easier way but it doesn't look like there is. Here is one method:
http://binwaheed.blogspot.com/2011/05/android-display-title-on-marker-in.html
Also I highly recommend using anti-aliasing unless you want ugly text:
TextPaint paintText = new TextPaint(Paint.ANTI_ALIAS_FLAG);

I used a Toast to display the text indicated by the marker. Here's how I solved it for a demo project:
-- begin Location.java --
package com.cb2enterprises.geocode;
import com.google.android.maps.GeoPoint;
public class Location
{
public GeoPoint Point;
public String Title;
public String Snippet;
public Location(GeoPoint point, String title, String snippet)
{
Point = point;
Title = title;
Snippet = snippet;
}
}
-- end --
-- begin PushpinOverlay.java --

import java.util.ArrayList;
import java.util.List;
public class PushpinOverlay extends ItemizedOverlay<OverlayItem>
{
private List<Location> mItems;
Context mContext = null;
public PushpinOverlay(Context context, Drawable marker)
{
super(boundCenterBottom(marker));
mContext = context;
}
public void setItems(ArrayList<Location> items)
{
mItems = items;
populate();
}
#Override
protected OverlayItem createItem(int i)
{
return new OverlayItem(mItems.get(i).Point, mItems.get(i).Title, mItems.get(i).Snippet);
}
#Override
public int size() {
return mItems.size();
}
#Override
protected boolean onTap(int i)
{
Toast msg = Toast.makeText(mContext, mItems.get(i).Title, Toast.LENGTH_LONG);
msg.setGravity(Gravity.CENTER, msg.getXOffset() / 2, msg.getYOffset() / 2);
msg.show();
return true;
}
}
-- end --
