OverlayItem over11 = new OverlayItem(point, "offff", "over5");


itemizedOverlay11.addOverlay(over11);

//开发者_如何学GoThe constructor HelloItemizedOverlay(Drawable, tryanabtry.MyLocationListener) is undefined

Make sure you include the class HelloItemizedOverlay in your project and you are calling the constructor correctly....
