Hi, I have the follow code on my application:
In the class Prueba:
import android.os.Bundle;
import android.view.*;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
public class prueba extends MapActivity {
Drawable defaultMarker = getResources().getDrawable(
R.drawable.mark);
Canvas ruta = new Canvas();
MapView map;
GeoPoint Point = new GeoPoint((int) (-1.416402 * 1000000), (int)
(-78.025078 * 1000000));
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
map = (MapView) findViewById(R.id.map);
map.getController().setCenter(Point);
map.displayZoomControls(true);
map.getController().setZoom(7);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0,1,2, "My Location");
//menu 1
SubMenu sub1 = menu.addSubMenu(3, 2, 3,"Vistas");
sub1.add(3,3,1, "Satelite");
sub1.add(3,4,2, "Trafico");
//menu 2
SubMenu sub = menu.addSubMenu(2, 5, 1,"Zoom");
sub.add(2,6,1, "In");
sub.add(2,7,2, "Out");
return true;
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
super.onMenuItemSelected(featureId, item);
WhereAmIOverlay WhereAmIOverlay;
View zoomView;
switch (item.getItemId()) {
case 1:
defaultMarker.setBounds(0, 0,
defaultMarker.getIntrinsicWidth(),
defaultMarker.getIntrinsicHeight());
WhereAmIOverlay = new WhereAmIOverlay(this,defaultMarker);
map.getController().animateTo(Point);
map.getOverlays().add(WhereAmIOverlay);
zoomView = map.getZoomControls();
zoomView.setLayoutParams(new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
// map.addView(zoomView);
// map.displayZoomControls(true);
// map.getController().setZoom(16);
// map.setClickable(true);
//map.setEnabled(true);
return true;
case 3:
map.setSatellite(true);
return true;
case 4:
map.setSatellite(false);
return true;
case 6:
int level = map.getZoomLevel();
map.getController().setZoom(level + 1);
return true;
case 7:
int level1 = map.getZoomLevel();
map.getController().setZoom(level1 - 1);
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
In the class where should draw I got:
import java.util.ArrayList;
import java.util.List;
import android.graphics.*;
import android.graphics.drawable.Drawable;
import com.google.android.maps.*;
public class WhereAmIOverlay extends ItemizedOverlay< OverlayItem>{
private List<OverlayItem> mItemList = new
ArrayList<OverlayItem>();
prueba prueba;
GeoPoint geoPoint;
Drawable marker;
private Projection p;
Point point;
Paint paint;
public WhereAmIOverlay(prueba prueba,Drawable defaultMarker) {
super(defaultMarker);
this.prueba = prueba;
paint = new Paint();
mItemList.add(new OverlayItem(prueba.Point , "Title",
"Snippet"));
populate();
}
@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow)
{
super.draw(canvas, mapView, true);
p = mapView.getProjection();
point = p.toPixels(prueba.Point,null);
canvas.drawCircle(point.x, point.y, 10, paint);
}
@Override
protected OverlayItem createItem(int i) {
return mItemList.get(i);
}
@Override
public int size() {
return mItemList.size();
}
}
But It did'n work. Some help please. Thanks
