Это мой код основной деятельности

      // error in creating fragment 
      Log.e("MainActivity", "Error in creating fragment"); 
     } 
    } 
} 

и это фрагмент

package com.example.testnav; 

    import android.app.Fragment; 
    import android.os.Bundle; 
    import android.view.LayoutInflater; 
    import android.view.View; 
    import android.view.ViewGroup; 

    public class FragmentOne extends Fragment { 

    public FragmentOne(){} 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.fragment_one, container, false); 

     return rootView; 
    } 
    } 

это мой XML

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/drawer_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <!-- The main content view --> 
    <FrameLayout 
     android:id="@+id/content_frame" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <!-- The navigation drawer --> 
    <ListView android:id="@+id/left_drawer" 
     android:layout_width="240dp" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:choiceMode="singleChoice" 
     android:divider="#666" 

     android:dividerHeight="1dp" 
     android:background="#333" 
     android:paddingLeft="15sp" 
     android:paddingRight="15sp" 
     /> 

    </android.support.v4.widget.DrawerLayout> 

Answer 1

Попробуйте использовать FragmentActivity вместо Activity

public class MainActivity extends FragmentActivity 

и

default: 
    fragment = new FragmentOne(); 
    break; 

Answer 2

я получаю ту же ошибку. Необходимо изменить места буксировки следующим образом.

Во-первых, используйте FragmentActivity

public class MainActivity extends FragmentActivity 

Во-вторых, изменить getFragmentManager к getSupportFragmentManager:

FragmentManager fragmentManager = getSupportFragmentManager();
