添加自定义标记地图 - 机器人 [英] Adding a custom marker to map - Android

问题描述

目前，我有一个应用程序使用图形页面可显示谷歌地图给用户。

I currently have an app which displays google maps to the user using MapView.

我一直在试图把一个标记使用此code在地图上，

I have been trying to place a marker on the map using this code,

public boolean onTouchEvent(MotionEvent event, MapView mapView) {
        if (event.getAction() == 1) {
            GeoPoint p = mapView.getProjection().fromPixels((int) event.getX(),
                    (int) event.getY());
            DemoOverlay demoOverlay = new DemoOverlay(); 
            mapView.getOverlays().add(demoOverlay);

            mapView.invalidate();
        }
        return false;
    }

我有一个演示叠加设立这使标记在地图上，但是当我触摸屏的标志永远不会出现。

I have a Demo Overlay set up which puts a marker on the map, however when I touch the screen the marker never appears.

任何帮助将是AP preciated！

Any help would be appreciated !!!
