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:
package com.ShoppingList.Shops;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
import com.ShoppingList.R;
import com.google.android.maps.GeoPoint;

import android.graphics.Canvas;
import android.graphics.drawable.Drawable;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class ShowMap extends MapActivity {
private MapView mapView;
MapController mc;
#Override
protected void onCreate(Bundle savedInstanceState) {
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 --
package com.cb2enterprises.geocode;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.widget.Toast;
import android.view.Gravity;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
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 --

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.

I think this is the perfect example you are looking for:

In Google Maps, I'm dropping a pin on user's current location but now I want to give another functionality to user that he can drag that pin manually and drop anywhere on the map, also by the time he drops the pin manually I can receive a callback which gives me the Longitude and Latitude of that position where user drops that pin.
If you can give me some examples it will be greatly appreciable.
In the last few days I finally found how to implement those functions you described and because there was no answer in this question, I decided to post what I found even though there has been a long time since you asked and you may found another answer by yourself.
So, I used the code of this git. I managed to do all that you want except the callback that I didn't try it in that way. I am getting the position of the pin after pressing a button.
There is no need to post my AndroidManifest because I read that you had no problem with displaying your location, so the permissions needed were fine.
The only thing that was required to do, was to create an activity named MapsActivity.
This is the whole content of it:
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import android.widget.ImageButton;
import android.widget.Toast;
import common.logger.Log;
public class MapsActivity extends Activity implements
OnMapReadyCallback, GoogleMap.OnInfoWindowClickListener,
GoogleMap.OnMarkerDragListener {
LatLng position = new LatLng(34.6767, 33.04455);
final Marker marker_final = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.
map);
mapFragment.getMapAsync(this);
ImageButton returnback = (ImageButton)findViewById(R.id.returnback);
returnback.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MapsActivity.this.getApplicationContext(), position.latitude + ":" + position.longitude, Toast.LENGTH_LONG).show();
}
});
}
#Override
public void onMapReady(GoogleMap map) {
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 13));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(15);
map.animateCamera(zoom);
map.addMarker(new MarkerOptions()
.title("Shop")
.snippet("Is this the right location?")
.position(position))
.setDraggable(true);
// map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);
map.setOnMarkerDragListener(this);
}
#Override
public void onInfoWindowClick(Marker marker) {
Toast.makeText(this, marker.getTitle(), Toast.LENGTH_LONG).show();
}
#Override
public void onMarkerDragStart(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(), String.format("Drag from %f:%f",
position0.latitude,
position0.longitude));
}
#Override
public void onMarkerDrag(Marker marker) {
LatLng position0 = marker.getPosition();
Log.d(getClass().getSimpleName(),
String.format("Dragging to %f:%f", position0.latitude,

}

Anyway look at Google Driving Directions - MapView overlayed Also The Google Directions API
and using intent
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=xx.xx,xx.xx&daddr=xx.xx,xx.xx"));
startActivity(intent);
This blogpost can be a good startpoint: Android driving direction Route-Path
Worked fine for me.
Please help me out, I am working on a Project Xyz having the mapView with add multiple overlays and remove overlays as per userChoice.
To be more clear it filters the overlays as per user choice,,,,
Suppose showing favorite places, friends of a user...
PostLoginServiceHomeBean is my ArrayList with an ArrayList NearByFavoritePlacesList object
entry.getNearByFavoritePlacesList().get(i).getGpsLatitude()
.trim()
i.e by this i'm getting the multiple lat long form server...
The code runs f9 and add the multiple overlays to my map and shows name and address of repective place on overlay tap.But how could I remove the overlays form my map...
I am enclosing the code:Please find the code below:

Here I am giving one solution what I am getting from your question... You need to add Lat Long into Overlay item which is coming from server and add it to itemized overlay, after that when ever you would like to remove any Itemizedoverlay with specific lat long you can check and remove from map overlay as well.
I'm having some troubles with displaying ItemizedOverlay(s) on a map.
Here I extracted a simplified example of what I need to do.
Here's my Map class:
import java.util.Timer;
import java.util.TimerTask;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.util.Log;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
import com.google.android.maps.OverlayItem;
public class Map extends MapActivity {
protected static final String TAG = "Map";
private int test = 0;
private TestItemized items = null;
private Timer timer = new Timer();
private MapView map = null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.map = (MapView) this.findViewById(R.id.myMapView1);
this.map.setBuiltInZoomControls(true);
this.map.setSatellite(false);
this.map.setStreetView(true);
this.map.setClickable(true);
this.timer.scheduleAtFixedRate(new TimerTask(){
#Override
public void run() {
Log.d(TAG, "refeshing: "+ String.valueOf(test));
Drawable drawable = Map.this.getResources().getDrawable(R.drawable.androidmarker);
test++;
if (Map.this.items instanceof TestItemized && Map.this.map.getOverlays().contains(Map.this.items))
Map.this.map.getOverlays().remove(Map.this.items);
//some code might go here to retrieve new coordinates but this isn't a problem
Map.this.items = new TestItemized(drawable, Map.this);
double lat = 46.491734;
Log.d(TAG,"Latitude : "+ String.valueOf(lat));
double lng = 11.320365;
Log.d(TAG,"Longitude : "+ String.valueOf(lng));
OverlayItem item = new OverlayItem(new GeoPoint((int)(lat * 1E6), (int)(lng * 1E6)), String.valueOf(Map.this.test), "blah!");
Map.this.items.addOverlay(item);
Map.this.map.getOverlays().add(Map.this.items);
Log.d(TAG,"refreshing "+String.valueOf(test)+" is over");
}}, 1000,60000);
}
#Override
protected boolean isRouteDisplayed() {
return false;
}
}
I followed the guide provided by google to extends the ItemizedOverlay class
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.widget.Toast;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
#SuppressWarnings("rawtypes")
public class TestItemized extends ItemizedOverlay {
private Context mCtx;
private List<OverlayItem> mItems = new ArrayList<OverlayItem>();
public TestItemized(Drawable arg0) {
super(arg0);
}
/**
* #param defaultMarker
* #param mCtx
*/
public TestItemized(Drawable defaultMarker, Context mCtx) {
super(defaultMarker);
this.mCtx = mCtx;
}
public void addOverlay(OverlayItem overlay) {
this.mItems.add(overlay);
populate();
}
#Override
protected OverlayItem createItem(int i) {
return this.mItems.get(i);
}
#Override
public int size() {
return mItems.size();
}
/* (non-Javadoc)
* #see com.google.android.maps.ItemizedOverlay#onTap(int)
*/
#Override
protected boolean onTap(int index) {
OverlayItem item = this.mItems.get(index);
Toast.makeText(this.mCtx, item.getTitle() +" : " +item.getSnippet(), Toast.LENGTH_LONG).show();
return true;
}
}
As it is clear from the code I need to update at fixed times a map UI with possibly new positions to do so I'm using a timer, but I think I might fall in some kind of thread issues I don't know how to handle, since when running a test I can see in the Log what happens but no marker is drawn on the map. Does anybody know how to solve this kind of problem?
At the end of the run() method, after you finish updating your MapView you should call
Map.this.map.postInvalidate();
