我試圖做一個菜單來控制片段 - 屏幕。（就像Instagram的），當試圖顯示一些片段時，應用程序崩潰

但它崩潰：

線143上的「添加」：

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

是t這裏有什麼不對嗎？

佈局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".All" 
    android:orientation="vertical" > 

    <fragment 
     android:id="@+id/MapFragment" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.example.free.MainActivity" 
     android:layout_marginBottom="40dp"> 

    </fragment> 

    <fragment 
     android:id="@+id/AddFragment" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     class="com.example.free.Add" 
     android:layout_marginBottom="40dp"> 

    </fragment> 

    <Button 
     android:id="@+id/add" 
     android:layout_width="wrap_content" 
     android:layout_height="40dp" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentRight="true" 
     android:layout_toRightOf="@+id/imageView1" 
     android:text="Add" /> 

    <Button 
     android:id="@+id/map" 
     android:layout_width="wrap_content" 
     android:layout_height="40dp" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentLeft="true" 
     android:layout_toLeftOf="@+id/imageView1" 
     android:text="Map" /> 

    <ImageView 
     android:id="@+id/imageView1" 
     android:layout_width="wrap_content" 
     android:layout_height="40dp" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:src="@drawable/divider" /> 

</RelativeLayout>

感謝您的幫助！

編輯

現在我正在這樣做：

Fragment MapFragment = getSupportFragmentManager().findFragmentById(R.id.MapFragment);

發佈活動佈局和片段佈局。 – Luksprog

@Luksprog活動佈局非常長，但我添加了片段佈局。夠了嗎？ – NirPes

必須使用的，而不是活動FragmentActivity（如果您正在使用支持庫）。

AddFragment =（View）findViewById（R.id.AddFragment）;

這是錯誤的。閱讀這篇文章，如何使用片段：http://developer.android.com/reference/android/app/Fragment.html

順便說一下，您不能將片段投射到視圖。

我應該把它扔到什麼地方？我將我的活動更改爲FragmentActivity。 – NirPes

使用方法findFragmentById（）。看看我發佈的鏈接。 – Vladimir

我已經做到了。看看我編輯的帖子。現在我需要在碎片之間切換，並在需要時將它們中的每一個都放在前面。我怎樣才能做到這一點？ – NirPes

當試圖顯示一些片段時，應用程序崩潰
