列表片段没有出现，因为没有发现ID错误的视图

我试图启动列表片段，但它似乎只能在平板电脑上工作。当我在手机上运行我的应用程序时，应用程序崩溃。有谁知道如何解决这个问题？代码如下。列表片段没有出现，因为没有发现ID错误的视图

错误

Caused by: java.lang.IllegalArgumentException: No view found for id 0x7f0c0050 (com.apptacularapps.exitsexpertlondonlite:id/master_container) for fragment FragmentMainList{b76424 #1 id=0x7f0c0050}

MainActivity.java

public class MainActivity extends ActionBarActivity { 

    private boolean mTwoPane; 

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

     FragmentMainList newFragment = new FragmentMainList(); 
     FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); 
     transaction.replace(R.id.master_container, newFragment); 
     transaction.commit(); 

     if (findViewById(R.id.detail_container) != null) { 
      mTwoPane = true; 
     } 
    } 
}

activity_main.xml中

<fragment 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/list_main"

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".FragmentMainList" 
    tools:layout="@android:layout/list_content"/>

activity_main.xml中（sw600dp）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent"

</LinearLayout>

FragmentMainList.java

public class FragmentMainList extends android.support.v4.app.Fragment { 

    ListView list_main; 

    String[] listContent = { 
      "Item 1", 
      "Item 2", 
      "Item 3" 
    }; 

    private boolean mTwoPane; 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ 
     View v = inflater.inflate(R.layout.fragment_main_list, container, false); 
     list_main = (ListView)v.findViewById(R.id.list_main); 

     ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,listContent); 
     list_main.setAdapter(adapter); 

     return v; 
    } 
}

，那是因为你有这条线

transaction.replace(R.id.master_container, newFragment);

和你没有内部activity_main.xml任何布局与master_container

具有相同的ID
