我在 Eclipse（google-map Android）中有一个项目，它有三个 Activity 类。当我单击运行时，我希望 mainActivity 首先打开，但我不认为它是打开的，因为当这个人在 AVD 中运行时，它会打开一个未在下面的类中定义的位置。如何在我的 Eclipse 项目中指定启动 Activity？
public class LocalGeoPoints {
public Vector<OverlayItem> overlayitems;
public LocalGeoPoints()
{
overlayitems = new Vector<OverlayItem>();
populate();
}
void populate()
{
