Here's my class file MapView class file.
package com.example.hellomap;
import java.util.List;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;
import com.google.android.maps.OverlayItem;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.ZoomControls;
public class mymap extends MapActivity {
List<Overlay> mapOverlays;
Drawable drawable;
mapOverlay itemizedOverlay;
LinearLayout linearLayout;
MapView mapView;
ZoomControls mZoom;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mymap);
linearLayout = (LinearLayout) findViewById(R.id.zoomview);
mapView = (MapView) findViewById(R.id.mapview);
mZoom = (ZoomControls) mapView.getZoomControls();
linearLayout.addView(mZoom);
mapOverlays = mapView.getOverlays();
drawable = this.getResources().getDrawable(R.drawable.man);
itemizedOverlay = new mapOverlay(drawable);
GeoPoint point = new GeoPoint(19240000,-99120000);
OverlayItem overlayitem = new OverlayItem(point, "", "");
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
}
@Override
protected boolean isRouteDisplayed() {
return false;
}
}
Overlay Class file:
package com.example.hellomap;
import java.util.ArrayList;
import android.graphics.drawable.Drawable;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class mapOverlay extends ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>
();
public mapOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
// TODO Auto-generated constructor stub
}
@Override
protected OverlayItem createItem(int arg0) {
return mOverlays.get(arg0);
}
@Override
public int size() {
return mOverlays.size();
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
}
