How to make the touch event in openstreetmap android

I am suffering in OSM map. This new for me. I want to print the Toast message on Single-click and on Long press I try all things that can i do. But i don't get the right way. Here is my code. Please give me right way to solve this. Thanks in dvance. please
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map1);
final MapView mapView = (MapView) findViewById(R.id.mapViewosm);
mapView.setBuiltInZoomControls(true);
MapController myMapController = mapView.getController();
myMapController.setZoom(13);
ScaleBarOverlay myScaleBarOverlay = new ScaleBarOverlay(this);
mapView.getOverlays().add(myScaleBarOverlay);
Drawable marker = getResources().getDrawable(
android.R.drawable.star_big_on);
int markerWidth = marker.getIntrinsicWidth();
int markerHeight = marker.getIntrinsicHeight();
marker.setBounds(0, markerHeight, markerWidth, 0);
ResourceProxy resourceProxy = new DefaultResourceProxyImpl(
getApplicationContext());
myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy);
mapView.getOverlays().add(myItemizedOverlay);
GeoPoint myPoint1 = new GeoPoint(0 * 1000000, 0 * 1000000);
myItemizedOverlay.addItem(myPoint1, "myPoint1", "myPoint1");
GeoPoint myPoint2 = new GeoPoint(50 * 1000000, 50 * 1000000);
myItemizedOverlay.addItem(myPoint2, "myPoint2", "myPoint2");
myLocationOverlay = new MyLocationOverlay(this, mapView);
mapView.getOverlays().add(myLocationOverlay);
myLocationOverlay.enableMyLocation();
myLocationOverlay.runOnFirstFix(new Runnable() {
public void run() {
mapView.getController().animateTo(
myLocationOverlay.getMyLocation());
}
});

anotherOverlayItemArray.add(new OverlayItem("0, 0", "0, 0",
new GeoPoint(0, 0)));
anotherOverlayItemArray.add(new OverlayItem("US", "US", new GeoPoint(
38.883333, -77.016667)));
ItemizedIconOverlay<OverlayItem> anotherItemizedIconOverlay = new
ItemizedIconOverlay<OverlayItem>(
this, anotherOverlayItemArray, myOnItemGestureListener);
mapView.getOverlays().add(anotherItemizedIconOverlay);
}
// 1st
OnItemGestureListener<OverlayItem> myOnItemGestureListener = new
OnItemGestureListener<OverlayItem>() {
#Override
public boolean onItemLongPress(int arg0, OverlayItem arg1) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "long tap",
Toast.LENGTH_SHORT).show();
return true;
}
#Override
public boolean onItemSingleTapUp(int index, OverlayItem item) {
Toast.makeText(getApplicationContext(), "single tap",
Toast.LENGTH_SHORT).show();
Toast.makeText(
Map.this,
item.mDescription + "\n" + item.mTitle + "\n"
+ item.mGeoPoint.getLatitudeE6() + " : "
+ item.mGeoPoint.getLongitudeE6(),
Toast.LENGTH_LONG).show();
return true;
}
};

in osm you can use MapEventsReceiver like blew to detect taps:
MapEventsReceiver mReceive = new MapEventsReceiver() {
#Override
public boolean singleTapConfirmedHelper(GeoPoint p) {
// write your code here
return false;
}
#Override
public boolean longPressHelper(GeoPoint p) {
// write your code here
return false;
}
};
MapEventsOverlay OverlayEvents = new MapEventsOverlay(getBaseContext(), mReceive);
map.getOverlays().add(OverlayEvents);

Finally i got solution for this problem. here is my answer
#Override
public boolean onSingleTapConfirmed(MotionEvent e, MapView mapView) {
Projection proj = mapView.getProjection();
p = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY());
proj = mapView.getProjection();
loc = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY());
String longitude = Double
.toString(((double) loc.getLongitudeE6()) / 1000000);
String latitude = Double
.toString(((double) loc.getLatitudeE6()) / 1000000);
Toast toast = Toast.makeText(getApplicationContext(),
"Longitude: "
+ longitude + " Latitude: " + latitude, Toast.LENGTH_SHORT);
toast.show();
return true;
}
private void addLocation(double lat, double lng) {
// ---Add a location marker---
p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));
Drawable marker = getResources().getDrawable(
android.R.drawable.star_big_on);
int markerWidth = marker.getIntrinsicWidth();
int markerHeight = marker.getIntrinsicHeight();
marker.setBounds(0, markerHeight, markerWidth, 0);
ResourceProxy resourceProxy = new DefaultResourceProxyImpl(
getApplicationContext());
myItemizedOverlay = new MyItemizedOverlay(marker, resourceProxy);
List<Overlay> listOfOverlays = mapView.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(myItemizedOverlay);
mapView.invalidate();
}

Marker on OpenStreetMap is draw slow

I am using OSM maps in my App. I am using 3.0.8 jar file for osmdroid. i have an issue with when i draw custom marker on Map it draw after 2-3 seconds. I goggled it find a solution that use library 3.0.5 osmdroid. when i tried it gives error that android dependencies failed. so please give me way that can i solve this problem.
here is my code for draw a custom marker.

The first thing I would try to is to stop allocating Bitmaps every draw cycle. Your draw() methods should be as fast as possible and allocating objects in that method will surely slow things down - especially if the garbage collector has to run. You should create all those Bitmaps in the constructor and store them in variables. Also it is recommended that you don't call toPixels() every draw cycle if you can avoid it - call it only when the location changes and store it (and update it if the zoom level changes).
Take a look at the sample application OpenStreetMapViewer for some well-crafted examples of how to use osmdroid.

google map android marker always point on a same position?

i want to display my location and destination location at map. the problem is that the destination location always point at same location even if i change another destination long and lat...
here is the code
protected void tampilkanPosisikeMap(Location newLocation) {
List<Overlay> overlays = mapView.getOverlays();
if (overlays.size() > 0) {
for (Iterator iterator = overlays.iterator(); iterator.hasNext();) {
iterator.next();
iterator.remove();
}
}
GeoPoint geopoint = new GeoPoint(
(int) (newLocation.getLatitude() * 1E6), (int) (newLocation
.getLongitude() * 1E6));
GeoPoint myposition = geopoint;
Location locationA = new Location("point A");
Location locationB = new Location("point B");
locationA.setLatitude(geopoint.getLatitudeE6() / 1E6);
locationA.setLongitude(geopoint.getLongitudeE6() / 1E6);
Drawable icon1 = getResources().getDrawable(R.drawable.user);
icon1.setBounds(0, 0, icon1.getIntrinsicWidth(), icon1
.getIntrinsicHeight());
MyItemizedOverlay overlay1 = new MyItemizedOverlay(icon1, this);
OverlayItem item1 = new OverlayItem(geopoint, "Posisi Anda", "Lat:"
+ locationA.getLatitude() + "\nLng:" + locationA.getLongitude());
overlay1.addItem(item1);
mapView.getOverlays().add(overlay1);
String lat2,longi2;
String nama_rs;String alamat_rs;
nama_rs = getIntent().getExtras().getString("namarsakit");
alamat_rs = getIntent().getExtras().getString("alamatrsakit");
lat2 = getIntent().getExtras().getString("lat");
longi2 = getIntent().getExtras().getString("longi");
Double lintang_rs = Double.parseDouble(lat2);
Double bujur_rs = Double.parseDouble(longi2);
GeoPoint geopoint1 = new GeoPoint(
(int) (lintang_rs * 1E6),
(int) (bujur_rs * 1E6));
locationB.setLatitude(geopoint1.getLatitudeE6() / 1E6);
locationB.setLongitude(geopoint1.getLongitudeE6() / 1E6);
DecimalFormat formatData = new DecimalFormat("#.#");
float distance = (float) locationA.distanceTo(locationB) / 1000;

jarak = String.valueOf(formatData.format(distance));
Drawable icon = getResources().getDrawable(R.drawable.marker); //

MyItemizedOverlay overlay = new MyItemizedOverlay(icon, this); //
OverlayItem item = new OverlayItem(geopoint1, nama_rs, //

Toast.makeText(MapDetailActivity.this,"nama = "+nama_rs+"lat tujuan= "+lintang_rs+"long tujuan = "+bujur_rs, Toast.LENGTH_SHORT).show();
mapView.getController().animateTo(geopoint1);
}
this is the destination code from above :
String lat2,longi2;

alamat_rs = getIntent().getExtras().getString("alamatrsakit");

For You to be able to show your Current location you must tap on to GPS location provider or Network Location provider. Looking at your code I cannot see any of this. Please note on emulator DDMS will default to a specific location. unless you supply one yourself

Android google maps show geo points which are closest to current location

Is there any way If I have like 100 geo points added in my MapActivity and I want to show only these which are like 1000m away from my current location. The other ones should not be visible on the map.
Any suggestions?

Ok, here is the example. You can subclass Overlay class and override draw method. Whenever the Overlay is invalidated, you should check if your points are within 1000m from your location. Off course, you should know your location within your overlay class. The flowing is the example:
public class MyMapOverlay extends Overlay {
Bitmap bmp;
Context context;
public MyMapOverlay()
{
bmp = BitmapFactory.decodeResource(MyApplication.getContext().getResources(), R.drawable.myplace);
}
#Override
public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when)
{
super.draw(canvas, mapView, shadow);
Point screenPts = new Point();
for(int i = 0;i<points.size(); i++)
{
GeoPoint point = points.get(i);
Location locationA = new Location("point " + String.valueOf(i));
locationA.setLatitude(point.getLatitudeE6());
locationA.setLongitude(point.getLongitudeE6());
float distance = myLocation.distanceTo(locationA);
if(distance < 1000.0)
{
mapView.getProjection().toPixels(p, screenPts);
canvas.drawBitmap(bmp, screenPts.x-bmp.getWidth()/2, screenPts.y-bmp.getHeight(), null);
}
}
return true;
}

With some help of the first answer I find this solution :
if(location != null){
Location locA = new Location("gps");
GeoPoint myLoc = new GeoPoint((int)(location.getLatitude() * 1E6), (int)(location.getLongitude() * 1E6));
mapController.animateTo(myLoc);
String sqlbars = "SELECT DISTINCT id, latitude, longitude, address, " +
" (SELECT category FROM bars_categories WHERE bar_id=bars.id) AS category " +
" FROM bars WHERE is_active=1";
Cursor curBars = dbHelper.executeSQLQuery(sqlbars);
if(curBars != null){
if(curBars.getCount() > 0){
for(curBars.move(0);curBars.moveToNext();curBars.isAfterLast()){
double latitude = curBars.getDouble(curBars.getColumnIndex("latitude"));
double longitude = curBars.getDouble(curBars.getColumnIndex("longitude"));
final List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = SofiaLiveNearbyActivity.this.getResources().getDrawable(R.drawable.pin_map_icon);
int markerWidth = drawable.getIntrinsicWidth();
int markerHeight = drawable.getIntrinsicHeight();
drawable.setBounds(0, markerHeight, markerWidth, 0);
final HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable, SofiaLiveNearbyActivity.this);
GeoPoint point = new GeoPoint((int)(latitude * 1E6),(int)(longitude *1E6));
OverlayItem overlayitem = new OverlayItem(point, "Type: "+category+"\n----------------\nAddress: "+address, id);
locA.setLatitude(latitude);
locA.setLongitude(longitude);
float distance = location.distanceTo(locA);
if(distance < 1000.0){
itemizedoverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedoverlay);
}
}
}
curBars.close();
}
and it worked.

use:
EditText name = (EditText) GooglemapsActivity.this.findViewById(R.id.txtMapSearch);
instead of
EditText name = (EditText) this.findViewById(R.id.txtMapSearch);

I got a solution to the problem. In the OnTouchEvent where i am creating the toast, i needed to set the text in my edit box at that position. Thanks for trying though.
here is the code:
public class GooglemapsActivity extends MapActivity
{
EditText txtSearch;
EditText TravelFrom;
MapView mapView;
MapController mc;
GeoPoint p;
class MapOverlay extends com.google.android.maps.Overlay
{
#Override
public boolean draw(Canvas canvas, MapView mapView,
boolean shadow, long when)
{
super.draw(canvas, mapView, shadow);
//---translate the GeoPoint to screen pixels---
Point screenPts = new Point();
mapView.getProjection().toPixels(p, screenPts);
//---add the marker---
Bitmap bmp = BitmapFactory.decodeResource(
getResources(), R.drawable.icon);
canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);
return true;
}
#Override
public boolean onTouchEvent(MotionEvent event, MapView mapView)
{
//---when user lifts his finger---
//---when user lifts his finger---
if (event.getAction() == 1) {
GeoPoint p = mapView.getProjection().fromPixels(
(int) event.getX(),
(int) event.getY());
Geocoder geoCoder = new Geocoder(
getBaseContext(), Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(
p.getLatitudeE6() / 1E6,
p.getLongitudeE6() / 1E6, 1);
String add = "";
if (addresses.size() > 0)
{
for (int i=0; <addresses.get(0).getMaxAddressLineIndex();
i++)
add += addresses.get(0).getAddressLine(i) + "\n";
}
txtSearch = (EditText) GooglemapsActivity.this.
findViewById(R.id.txtMapSearch);
txtSearch.setText(add);
Toast.makeText(getBaseContext(), add, Toast.LENGTH_SHORT).show();
}
