以編程方式將視圖添加到片段onCreateView方法

Question

我正在使用片段爲API15構建一個android應用程序。

佈局是：

1. activity_page_detail.xml
2. activity_page_list.xml
3. activity_page_twopane.xml
4. fragment_page_detail.xml

Java文件是：

1. pageDetailActivity.java
2. pageDetailFragment.java
3. pageListActivity.java
4. pageListFragment.java
5. DummyContent.java

在activity_page_detail.xml：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:id="@+id/page_detail_container" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".pageDetailActivity" 
tools:ignore="MergeRootFrame"/> 

而且在activity_page_list .xml：

而且在activity_page_twopane.xml：

<LinearLayout 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" 
android:layout_marginLeft="16dp" 
android:layout_marginRight="16dp" 
android:baselineAligned="false" 
android:divider="?android:attr/dividerHorizontal" 
android:orientation="horizontal" 
android:showDividers="middle" 
tools:context=".pageListActivity" > 

<!-- 
This layout is a two-pane layout for the pages 
master/detail flow. See res/values-large/refs.xml and 
res/values-sw600dp/refs.xml for an example of layout aliases 
that replace the single-pane version of the layout with 
this two-pane version. 

For more on layout aliases, see: 
http://developer.android.com/training/multiscreen/screensizes.html#TaskUseAliasFilters 
--> 



<fragment 
    android:id="@+id/page_list" 
    android:name="com.application.trigger.pageListFragment" 
    android:layout_width="0dp" 
    android:layout_height="match_parent" 
    android:layout_weight="1" 
    tools:layout="@android:layout/list_content" /> 

<FrameLayout 
    android:id="@+id/page_detail_container" 
    android:layout_width="0dp" 
    android:layout_height="match_parent" 
    android:layout_weight="3" /> 

</LinearLayout> 

而且在fragment_page_detail.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
tools:context=".pageDetailFragment" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" 
tools:ignore="contentDescription" 
android:background="#000"> 

<TextView 
    android:id="@+id/page_detail" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="16dp" 
    android:textColor="#fafafa" 
    android:textIsSelectable="true" 
    android:textAppearance="@android:attr/textAppearanceListItemSmall" 
    /> 

<LinearLayout 
    android:id="@+id/linear_vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background="#7f7f7f" 
    /> 

</LinearLayout> 

Java源代碼是：

的問題是，如何加入以編程方式查看最後一個java代碼中的每個碎片細節也許在onCreateView方法？我的代碼在案例1中提到的功能退出程序並且不起作用。

Answer 1

堆棧跟蹤清楚地說，問題是，你正在嘗試添加已連接到一個ViewGroup中（其父）視圖到另一個的ViewGroup。

一個視圖不能有兩個不同的父母，因此錯誤。

您可以在將父視圖添加到新父視圖之前從其父視圖中刪除該視圖，或者只是多次膨脹相同的XML。如果您將一個XML膨脹多一個，您將創建新的View對象，並且可以將它們附加到不同的父項。
