There is already an overlay, drawing something on a map view. I want to add another overlay and a customized item to the map view. Nothing shows. What's wrong with my code? Thanks heaps.
My sub-class of ItemizedOverlay
public class PinItemizedOverlay extends ItemizedOverlay {
private static int MAX_PIN = 3;
private OverlayItem overlays[] = new OverlayItem[MAX_PIN];
private int index = 0;
private boolean full = false;
private Context context;
public PinItemizedOverlay(Context context, Drawable defaultMarker) {
//super(boundCenterBottom(defaultMarker));
super(boundCenterBottom(defaultMarker));
this.context = context;
}
#Override
public OverlayItem createItem(int index) {
return overlays[index];
}
public int size(){
if (full) {
return overlays.length;
} else {
return index;
}
}
public void addOverlay(OverlayItem overlay) {
if (index < MAX_PIN) {
overlays[index] = overlay;
} else {
return;
}
index++;
populate();
}
}
My customized overlay item
public class LocationPinItem extends OverlayItem{
public LocationEntity location;
public LocationPinItem(GeoPoint point, int iconRes, LocationEntity location){
//super(point,null,null);
super(point, null, null);
Drawable marker = getApplicationContext().getResources().getDrawable(iconRes);
super.setMarker(marker );
this.location = location;
}
}
And the function where I add the customized item (it's a drop pin):
private void createMarkerAt(LocationEntity location, String extra, int iconRes, boolean clear, boolean animate) {
if(location == null) {
return;
}
GeoPoint point = new GeoPoint((int) (location.latitude * 1E6), (int) (location.longitude * 1E6));
LocationPinItem pinItem = new LocationPinItem(point,R.drawable.ic_swap,location);
PinItemizedOverlay pinOverlay = new PinItemizedOverlay(getApplicationContext(),mMapDrawable) ;
pinOverlay.addOverlay(pinItem);
mMapView.removeAllViews();
mMapView.postInvalidate();
mMapView.getOverlays().add(pinOverlay);
if(animate) {
mMapView.getController().animateTo(location.toGeoPoint());
}
}
never mind, I figured it out: the newly-added overlay occludes the previous overlay

Now I can show the map and markers that are defined in the program, but I need to add markers to touched location.
I think I know the way to do this, which is:
1 To set something like onTouchEventListener to the MapView;
2 Get the position information from Listener;
3 Set the marker according to the position information.
But I am too new to this to find out how to write code to achieve it, especially the step 1. I mean I don't understand how to use the solution like Add marker on touched location using google map in Android .My problem is more fundamental. I dont know how to set eventListener for my MapView and which eventListener should I use. https://developer.mapquest.com/content/mobile/android/documentation/api/com/mapquest/android/maps/Overlay.OverlayTouchEventListener.html This OverlayTouchEventListener seems to be the one but cant find an useful guide for it.
So could some one tell me how to do this in detail?
Eg.How to set the listener and which listener to choose?
Try this...
1. Create interface MyGeoPointListener.java
public interface MyGeoPointListener {
public void GetGeoPoint(GeoPoint geopoint);
}
2. Create Overlay class:
import com.mapquest.android.maps.ItemizedOverlay;
import com.mapquest.android.maps.OverlayItem;
class DynamicMarkerOverlay extends ItemizedOverlay<OverlayItem> {
private boolean isPinch = false;
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
private MyGeoPointListener geoPointListener;
public DynamicMarkerOverlay(Drawable defaultMarker,
MyGeoPointListener geoPointListener) {
super(boundCenterBottom(defaultMarker));
this.geoPointListener = geoPointListener;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
#Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
#Override
public int size() {
return mOverlays.size();
}
#Override
public boolean onTap(GeoPoint geoPoint, MapView map) {
if (isPinch) {
return false;
} else {
if (geoPoint != null) {
if (null != geoPointListener) {
geoPointListener.GetGeoPoint(geoPoint);
}
return true;
} else {
if (null != geoPointListener) {
geoPointListener.GetGeoPoint(null);
}
return false;
}
}
}
#Override
public boolean onTouchEvent(MotionEvent event, MapView mapView) {
int fingers = event.getPointerCount();
if (event.getAction() == MotionEvent.ACTION_DOWN) {
isPinch = false; // Touch DOWN, don't know if it's a pinch yet
}
if (event.getAction() == MotionEvent.ACTION_MOVE && fingers == 2) {
isPinch = true; // Two fingers, def a pinch
}
return super.onTouchEvent(event, mapView);
}
}
3. Implement MyGeoPointListener in activity
like,
public class MainActivity extends MapActivity implements MyGeoPointListener {
4. Override MyGeoPointListener:
.....
#Override
public void GetGeoPoint(GeoPoint geopoint) {
if (null != geopoint) {
String msg = "Lat: " + geopoint.getLatitudeE6() / 1E6 + " - "
+ "Lon: " + geopoint.getLongitudeE6() / 1E6;
Toast toast = Toast.makeText(MyLocationMap.this, msg,
Toast.LENGTH_SHORT);
toast.show();
List<Overlay> mapOverlays = myMap.getOverlays();
OverlayItem overlayitem = new OverlayItem(geopoint, "address_name",
"address");
Drawable icon = getResources().getDrawable(
R.drawable.location_marker);
DynamicMarkerOverlay customoverlay = new DynamicMarkerOverlay(icon,
this);
customoverlay.addOverlay(overlayitem);
mapOverlays.add(customoverlay);
myMap.getController().animateTo(geopoint);
}
}
.....
5. In OnCreate()
......
public MapView myMap;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_map_layout);
.......
.......
myMap = (MapView) findViewById(R.id.map);
Drawable marker = getResources().getDrawable(R.drawable.ic_launcher);
marker.setBounds(0, 0, marker.getIntrinsicWidth(),
marker.getIntrinsicHeight());
myMap.getOverlays().add(new DynamicMarkerOverlay(marker, this));
......
}
6. Result:
I want to add an info window on top of Each marker set when user tap on a marker. Here is my code. The marker is fine i need only the infowindow appears on top of it. how can i achieve this, here is my code
public class MainActivity extends MapActivity {
#Override

itemizedOverlay.addOverlayItem(48857522, 2294496, "Paris", eiffelTower);
mapView.getOverlays().add(itemizedOverlay);
MapController mc = mapView.getController();
mc.setCenter(new GeoPoint(51035349, 2370987)); // Dunkerque, Belgium
mc.zoomToSpan(itemizedOverlay.getLatSpanE6(), itemizedOverlay.getLonSpanE6());

boundCenter(marker);
}
The onTap() method working when there is minimum one point on map but when I remove all points from map then onTap() method is not working and I am unable to add points on map.
Please help...
Code:
private class CustomItemizedOverlay2 extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> mapOverlays = new ArrayList<OverlayItem>();
private Context context;
private GeoPoint center = null;
public CustomItemizedOverlay2(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
public CustomItemizedOverlay2(Drawable defaultMarker, GeoPoint point) {
this(defaultMarker);
OverlayItem overlayItem = new OverlayItem(point, "", "");
mapOverlays.add(overlayItem);
populate();
}
public CustomItemizedOverlay2(Drawable defaultMarker, Context context,
String result) {
this(defaultMarker);
this.context = context;
for (int i = 0; i < geoPointList.size(); i++) {
OverlayItem overlayItem = new OverlayItem(geoPointList.get(i),
"abc", "point" + i);
mapOverlays.add(overlayItem);
}
populate();
}
#Override
protected OverlayItem createItem(int i) {
return mapOverlays.get(i);
}
#Override
public int size() {
return mapOverlays.size();
}
#Override
public boolean onTap(GeoPoint point, MapView mapView) {
int size = geoPointList.size();
if (size < 2) {
geoPointList.add(point);
count++;
int lat = point.getLatitudeE6();
int longi = point.getLongitudeE6();
Drawable image = gMap.this.getResources().getDrawable(
R.drawable.pushpin);
CustomItemizedOverlay2 addPointItemizedOverlay = new CustomItemizedOverlay2(
image, point);
mapView.getOverlays().add(addPointItemizedOverlay);
mapView.invalidate();
}
return super.onTap(point, mapView);
}
}
The onTap method add point if the number of points in geoPointList is less than two.
Finally solved, as I have implemented the custom MapOverlay and use the onTap method in it instead of using in CustomItemizedOverlay2.
I can't succeed to put a custom centered overlay item on my map. It always appears centered on bottom and middle. Here is my code:
------------My overlay item class-------------
public class EditionThumbOverlayItem extends OverlayItem {
public EditionThumbOverlayItem(GeoPoint aGeoPoint, Resources resources) {
super("", "", aGeoPoint);
Drawable pinThumbDrawable = resources.getDrawable(R.drawable.pin_thumb);
pinThumbDrawable.setBounds(pinThumbDrawable.getIntrinsicWidth() * (-2 / 5),
pinThumbDrawable.getIntrinsicHeight() * (-2 / 5), pinThumbDrawable.getIntrinsicWidth() * 3 / 5,
pinThumbDrawable.getIntrinsicHeight() * 3 / 5);
setMarker(pinThumbDrawable);
}
}
-------------my itemized overlay class-----------------
public class PinThumbOverlay extends ItemizedOverlay<OverlayItem> {
// Only one item can be set on this overlay
private OverlayItem mEditionThumb;
public PinThumbOverlay(Drawable pDefaultMarker, ResourceProxy pResourceProxy) {
super(pDefaultMarker, pResourceProxy);
}
#Override
public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) {
return false;
}
#Override
protected OverlayItem createItem(int arg0) {
return mEditionThumb;
}
#Override
public int size() {
if (mEditionThumb == null) {
return 0;
} else {
return 1;
}
}
public void addOverlayItem(OverlayItem overlay) {
mEditionThumb = overlay;
populate();
}
public void removeOverlayItem() {
mEditionThumb = null;
populate();
}
}
-----------------itemized overlay creation----------------------
DefaultResourceProxyImpl defaultResouceProxyImpl = new DefaultResourceProxyImpl(getApplicationContext());
Drawable defaultPinEdition = getResources().getDrawable(R.drawable.pin_thumb);
mPinThumbOverlay = new PinThumbOverlay(defaultPinEdition, defaultResouceProxyImpl);
mMapView.getOverlays().clear();
mMapView.getOverlays().add(mPinThumbOverlay);
-------------------Overlay item creation-------------------------
EditionThumbOverlayItem editionThumb = new EditionThumbOverlayItem(new GeoPoint(mCurrentUserLocation),
getResources());
mPinThumbOverlay.addOverlayItem(editionThumb);
As a note: I use osmdroid map, not default google map api.
It seems that osmdroid overwrites any values you set with the drawble.setBounds() method in the onDrawItem method in ItemizedOverlay:
protected void onDrawItem(final Canvas canvas, final Item item, final Point curScreenCoords) {
final int state = (mDrawFocusedItem && (mFocusedItem == item) ? OverlayItem.ITEM_STATE_FOCUSED_MASK
: 0);
final Drawable marker = (item.getMarker(state) == null) ? getDefaultMarker(state) : item
.getMarker(state);
final HotspotPlace hotspot = item.getMarkerHotspot();
boundToHotspot(marker, hotspot);
// draw it
Overlay.drawAt(canvas, marker, curScreenCoords.x, curScreenCoords.y, false);
}
Or rather, the actual overwriting will be done in the boundToHotspot(marker,hotspot); method.
To overcome this set your hotspot on your OverlayItem instead of setting the bounds on the drawable.
Example:
GeoPoint point = new GeoPoint(currentLoc);
OverlayItem item = new OverlayItem("my location", "my loc", point);
item.setMarkerHotspot(HotspotPlace.BOTTOM_CENTER);
This should produce the result your looking for.
If you just want to put a marker in the map center, use this code snippet:
public class MyActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.main);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setMultiTouchControls(true);
mapView.setClickable(true);
mapView.setUseDataConnection(true);
mapView.getController().setZoom(MAP_DEFAULT_ZOOM);
mapView.setTileSource(TileSourceFactory.MAPNIK);
resourceProxy = new DefaultResourceProxyImpl(getApplicationContext());
GeoPoint location = getLocation()
ItemizedIconOverlay<OverlayItem> currentLocationOverlay;
Drawable marker = this.getResources().getDrawable(R.drawable.custom_marker);
OverlayItem myLocationOverlayItem = new OverlayItem("Here", "Current Position", location);
myLocationOverlayItem.setMarker(marker);
final ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(myLocationOverlayItem);
currentLocationOverlay = new ItemizedIconOverlay<OverlayItem>(items,
new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
return true;
}
public boolean onItemLongPress(final int index, final OverlayItem item) {
return true;
}
}, resourceProxy);
mapView.getOverlays().add(this.currentLocationOverlay);
mapView.getController().setCenter(location);
}
i have written a google maps mulitple markers application.When i tap on a marker i have written a code to display a nine patch image on the top of marker.But here when i taps the nine patch image is not displaying on the top of a marker in a google map.It is displaying just after the marker and at the same time the bottom edge of the nine patch image is touching the surface of the map.How can i display the nine patch image bottom exactly on the top the marker when i tap on that marker.My code is as follows.
