在android上谷歌地图应用程序中设置自定义缩放按钮的操作意外停止

我使用下面的代码创建带有googlemaps api的应用程序，但异常错误

mapView = (MapView) findViewById(R.id.mapView);
LinearLayout zoomLayout = (LinearLayout) findViewById(R.id.zoom);
View zoomView = mapView.getZoomControls();
zoomLayout.removeAllViews();
zoomLayout.addView(zoomView, new LinearLayout.LayoutParams(
        android.widget.LinearLayout.LayoutParams.WRAP_CONTENT,
        android.widget.LinearLayout.LayoutParams.WRAP_CONTENT));
mapView.displayZoomControls(true);

mapView在

中定义为私有。 在查看zoomView=mapView.GetZoomControl（）中eclipse显示此警告：类型MapView中的getZoomControl（）方法已被弃用 logCat是：

在自定义缩放按钮之前，请运行地图并正确显示。我怎样才能解决这个问题？谢谢

map.setBuiltInZoomControls(true);

试试看。

请描述一下为什么会回答这个问题。谢谢，但我以前测试过。我在StackOverflow中的搜索结果中测试了许多解决方案。这个logCat错误

参考

setContentView（R.layout.activity_maps）；

。为什么？希望您在类中使用extends MapActivity而不是Activity@Hari是的，我使用这个：
