You should use this:

MapLocationViewer mlv = (MapLocationViewer)this.findViewById(R.id.map_location_viewer);
MapView mp = mlv.getMapView();

I noticed you have a getter for the mapview in your MapLocationViewer which looks to be a java layout. Is there a way to call that getter? I’ve tried using

mv = (MapView)this.findViewById(R.id.map_location_viewer);

in the MapActivity class but since MapLocationViewer is a linear layout, it throws an error because it’s not a MapView. I mainly wanted to get the MapView so I can move to the user’s current gps location. Thanks!

Thanks again.

i read the two tutorials again.

tutorial2 teaches me how to draw on the canvas directly when user clicks the overlayitems.

tutorial5 teaches me how to show an anime when user clicks the button.

is that right?

i want to modify the tutorial2. when users clicks the overlayitems, show the info by pop a transparency panel instead of drawing on the canvas.

so first i create a layout like this

// id:xx

…

second, i try to change the method of displaying info.
in the MapLocationOverlay void draw(Canvas, MapView, Boolean)

// drawMapLocations(canvas, mapView, shadow)
// drawInfoWindow (canvas, mapView, shadow)
// i try to display some infomation just like tutorail5, so..

TransparentPanel popup= (TransparentPanel)findViewById(R.id.xx);
…
…
popup.setVisibility(View.VISIBLE);
popup.startAnimation( animShow );
showButton.setEnabled(false);
hideButton.setEnabled(true);

but the code cant pass the compile

You should reread the two tutorials as all the information is in there. You don’t need to do anything special with LocationOverlay and LocationViewer other than what’s in the tutorial. Not sure why you would need the findViewByid method in OverLay.

i want users click the specific location on map and pop it’s information(transparentPanel).

i have tried to modify LocationOverlay and LocationViewer, but i cant get the instance of popup, location_name..etc

becuz the findViewByid method doesnt work in OverLay.
how could I solve this problem

Just display the panel when the user touches the screen. I.e. listen for the onTouchEvent and then display the popup.
