Question

我有三个碎片，它们按如下所示排列：

“Frag A和Frag C没有连接，但是Frag B和C都是。每个片段包含1个listview所以每次触发一个事件时它都会转到下一个片段。”

片段A ---＆gt; （内部片段A）片段B ---＆gt; （Inside Frag B）Fragment C

片段A（main.xml）
片段B（R.id.contentFragment）
片段C（R.id.contentFragment）

我可以显示片段A和片段B并且没关系，但如果我从B调用片段C我得到了"No view found in contentFragment=0x7f040039"。

main.xml中

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:orientation="vertical"  
                android:background="@color/white" 
                android:id="@+id/frameLayout"    
                >

            <ListView
            android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_alignParentTop="true"
            android:layout_alignParentBottom="true"
            android:layout_height="wrap_content" 
            >
            </ListView>

    <FrameLayout 
    android:id="@+id/contentFragment"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_weight="1" >
     </FrameLayout>


    </FrameLayout>

</FrameLayout>

FragmentA.java

在片段A内打开片段B

 Fragment fragment1 = new FragmentB();

        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.replace(R.id.contentFragment, fragment1, fragMainGroups );
        transaction.addToBackStack(fragMainGroups);
        transaction.commit();

FragmentB.java

在片段B内打开片段C

     String fragGroups = "groups";

    Fragment fragment1 = new FragmentC();

    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    transaction.replace(R.id.contentFragment, fragment1, fragGroups );
    transaction.addToBackStack(fragGroups);
    transaction.commit();

FragmentC.java

内部碎片C

   public class FragmentItems extends ListFragment{

    public void onAttach(Activity activity) {
        super.onAttach(activity);
    }
            public void onActivityCreated(Bundle savedInstanceState) {
                super.onActivityCreated(savedInstanceState);
            }

            public void onCreate(Bundle e)
            {
                super.onCreate(e);
            }

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

                    return rootView;
                }
}

Answer 1

正如您的错误所述，您正在片段B中查找ID为contentFragmentTtems的视图，其主视图为contentFragment而不是整个main.xml。因此，如果您想添加新片段，您也应该从片段A中进行。

Answer 2

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:orientation="vertical"  
                android:background="@color/white" 
                android:id="@+id/frameLayout"    
                >

            <ListView
            android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_alignParentTop="true"
            android:layout_alignParentBottom="true"
            android:layout_height="wrap_content" 
            >
            </ListView>

    <FrameLayout 
    android:id="@+id/contentFragmentb"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_weight="1" >
     </FrameLayout>
<FrameLayout 
    android:id="@+id/contentFragmentc"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_weight="1" >
     </FrameLayout>

    </FrameLayout>

</FrameLayout>

这应该有用。
