线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这里有什么不对吗？

布局：

<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>

感谢您的帮助！

编辑

现在我正在这样做：

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

发布活动布局和片段布局。 – Luksprog

@Luksprog活动布局非常长，但我添加了片段布局。够了吗？ – NirPes

必须使用的，而不是活动FragmentActivity（如果您正在使用支持库）。

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

这是错误的。阅读这篇文章，如何使用片段：http://developer.android.com/reference/android/app/Fragment.html

顺便说一下，您不能将片段投射到视图。

我应该把它扔到什么地方？我将我的活动更改为FragmentActivity。 – NirPes

使用方法findFragmentById（）。看看我发布的链接。 – Vladimir

我已经做到了。看看我编辑的帖子。现在我需要在碎片之间切换，并在需要时将它们中的每一个都放在前面。我怎样才能做到这一点？ – NirPes

当试图显示一些片段时，应用程序崩溃
