非常奇怪的班级混乱

Question

我有一个操作菜单，我试图启动另一个活动，一旦图标被点击，但它导致错误恐慌。事实上，它似乎是走错了路。这是我的意思。这里的代码是：

@Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     if (id == R.id.mapIcon) { 
      Intent displayTheMap = new Intent(this, TheMap.class); 
        startActivity(displayTheMap); 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

但它返回：

04-18 06:19:16.201: E/AndroidRuntime(2079): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.gs.maps/com.gs.maps.TheMap}: java.lang.IllegalArgumentException: No view found for id 0x7f06003f (com.gs.maps:id/container) for fragment PlaceholderFragment{b3d8a760 #0 id=0x7f06003f} 

这究竟是为什么？它应该找到com.gs.maps.TheMap而不是com.gs.maps/com.gs.maps.TheMap为什么它得到一个错误的道路？我错过了什么？我知道这只是一小部分，但我目前无法找到解决方案。

完全logcat的例外：

的java的主类：

public class MainActivity extends ActionBarActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     if (savedInstanceState == null) { 
      getSupportFragmentManager().beginTransaction() 
        .add(R.id.container, new PlaceholderFragment()).commit(); 
     } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     MenuInflater actionMenue = getMenuInflater(); 
     actionMenue.inflate(R.menu.main_activity_bar, menu); 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     if (id == R.id.mapIcon) { 
      Intent displayTheMap = new Intent(this, TheMap.class); 
        startActivity(displayTheMap); 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    /** 
    * A placeholder fragment containing a simple view. 
    */ 
    public static class PlaceholderFragment extends Fragment { 

     public PlaceholderFragment() { 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 
      View rootView = inflater.inflate(R.layout.fragment_main, container, 
        false); 
      return rootView; 
     } 
    }

我有一个类似的问题一次，我还没有真正看过深入你的代码，但尝试更换这（你在哪里宣布新的意图）有：

Intent displayTheMap = new Intent(NAMEOFTHECLASSYOURIN.this, TheMap.class); 

看看是否能不这样做的伎俩。
