Answer 1

我只是想出了愚蠢的我的問題就出在這裏

地圖=（（MapFragment）getFragmentManager（） .findFragmentById（R.id.map））的GetMap（）;

它應該是

地圖=（（SupportMapFragment）getSupportFragmentManager（）findFragmentById（R.id.map）。）的GetMap（）;需要

也@Glenn活動的規定由FragmentActivity而不是活動 延長..因此解決

Answer 2

你好這是一個兼容性錯誤的：

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:

找你試着g要在代碼中使用Fragment，但要使Fragments能夠在Gingerbread及其下運行，則必須從Google導入兼容性庫：請參閱Android Support Library和此Answer。

因此，請務必將您的Activity成FragmentActivity和使用getSupportFragmentManager()，而不是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(); 
     }
