Add views programmatically to Fragment onCreateView method

Question

I'm using fragments to build an android app for API15.

Layouts are:

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

Java Files are:

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

In 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"/>

And in activity_page_list.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:ignore="contentDescription"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" 
android:gravity="center">

<ImageView
        android:id="@+id/logoimage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/logo" 
        android:layout_marginTop="20dp"
        android:layout_marginBottom="30dp"/>

<fragment
    android:id="@+id/page_list"
    android:name="com.application.trigger.pageListFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    tools:context=".pageListActivity"
    tools:layout="@android:layout/list_content" />

</LinearLayout>

And in 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>

And in 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>

                    website.put(Data.MIMETYPE, Website.CONTENT_ITEM_TYPE);
                    website.put(Website.URL, "http://company.com");     
                    data.add(website);

                    contact.putParcelableArrayListExtra(Insert.DATA, data);

                    int request_Code = 100;
                    startActivityForResult(contact, request_Code);

                    break;

                case 5:
                    ((TextView) rootView.findViewById(R.id.page_detail))
                    .setText("show text5");

                    break;
                }
            }

            return rootView;
        }
    }

The Question is that How to add view programmatically for each fragment detail at the last java code perhaps in onCreateView method? My Code at the mentioned function at case 1 exits the program and not works.

Answer 1

The stack trace clearly says that the problem is that you are trying to add a View that is already attached to a ViewGroup (its parent) to another VIewGroup.

A view cannot have two different parents, hence the error.

You could remove the view from its parent before adding it to the new parent, or simply inflate the same XML several times. If you inflate one XML more that one you will be creating new View objects,and you could attach them to different parents.
