Hi,
I'm not sure if this is the right place to post this, but I've run
into a wall on this. I'm writing an app that has certain locations
stored on the phone, and displays the locations on points drawn by an
Overlay on a Map. What I want to do is write it so that when the
person clicks on the point, a dialog shows up containing information
about that point. I've successfully used the OnTouchListener to do
this. However, the problem arises when I want to move the Map. Once I
click elsewhere on the map, it seems like the OnTouchListener just
dies and goes away so that every subsequent time I click on a point,
it will not show a Dialog. The OnTouchListener uses the Overlay's
onTouchEvent to see if the point is clicked. The Overlay recognizes
that the point is being clicked, but I cannot launch a Dialog from the
Overlay, which is the problem.
Thanks,
Andrew
Here is the code:
----------------------------------------------------------------------------------------------
OnTouchListener OTL = new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event){
if(mapOverlay.onTouchEvent(event, mapView)){
showDialog(DIALOG_ID);
mapView.invalidate();
return true;
}
return false;
}
};
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
adapter = new Adapter(this);
adapter.open();
mapView = (MapView) findViewById(R.id.mapview);
mapView.setSatellite(true);
mapView.setStreetView(true);
mapView.setBuiltInZoomControls(true);
c = adapter.getAll();
startManagingCursor(c);
mapController = mapView.getController();
mapOverlay = new MapOverlay(c);
mapView.getOverlays().add(mapOverlay);
mapView.setOnTouchListener(OTL);
mapView.postInvalidate();
}
