答案 0 :(得分：3)
你好，这是一个兼容性错误：
E/AndroidRuntime(6549): Caused by: java.lang.ClassNotFoundException: android.view.fragment in loader dalvik.system.PathClassLoader[/data/app/com.gaditek.ihistro-1.apk] 06-01 18:26:16.546:
您尝试在代码中使用Fragment，但要使Fragments在Gingerbread上运行，您必须从Google导入兼容性库：在此处查看Android Support Library和此{{ 3}}
因此，请确保将Activity变为FragmentActivity并使用getSupportFragmentManager()代替getFragmentManager()
public void addFragment(Fragment fragment, boolean addToBackStack,int transition)
{
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.simple_fragment, fragment, null);
ft.setTransition(transition);
if (addToBackStack)
ft.addToBackStack(null);
ft.commit();
}
答案 1 :(得分：1)
我只是弄清楚愚蠢的我这里的问题
map =（（MapFragment）getFragmentManager（）。findFragmentById（R.id.map））。getMap（）;
应该是
map =（（SupportMapFragment）getSupportFragmentManager（）。findFragmentById（R.id.map））。getMap（）;
同样如@Glenn所述，活动需要由FragmentActivity而不是Activity扩展 ..因此解决了
