[android-beginners] Launching a Dialog from an Overlay/MapActivity: msg#01135AndroidBeginners
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(); } --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
