android throw InflateException binary xml file line : Error inflating class fragment

Question

I got a Activity class which implement a Actionbar with two Tabs. Each Tab is calling a other Fragment??.class over the TabListener. If I start the Application the FragmentXY.class is called. I can switch to the second Tab without any problem. But if I switch back to the first Tab which contains the two other fragments as a split-screen, the application crashed and throw the Error :InflateException binary xml file line : Error inflating class fragment

tab = actionBar
    .newTab()
    .setText("My Box")
    .setIcon(android.R.drawable.ic_menu_help)
    .setTabListener(new MyTabListener<FragmentXY>(this, "myXY",FragmentXY.class));
    actionBar.addTab(tab);

tab = actionBar
    .newTab()
    .setText("QR-Code")
    .setIcon(android.R.drawable.ic_menu_add)
    .setTabListener(new MyTabListener<FragmentXYZ>(this, "barcode",FragmentXYZ.class));

actionBar.addTab(tab);

Each Fragment.class is calling a xml resource which contain once two other fragments or only one Fragment.

FragmentXY.class

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

first_tab.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >
    <fragment
        android:name="com.febro.myfragmenttest.ListFragment"
        android:id="@+id/listFragment"
        android:layout_width="250dp"
        android:layout_height="match_parent"
        android:layout_marginTop="?android:attr/actionBarSize"
        class="com.febro.myfragmenttest.ListFragment" ></fragment>

    <fragment
        android:name="com.febro.myfragmenttest.DetailFragment"
        android:id="@+id/detailFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.febro.myfragmenttest.DetailFragment" >
    </fragment>

</LinearLayout>

Is it a problem with the callback-methode?

Here is the full error report from logcat:

Answer 1

simply extends your class extends FragmentActivity

instead of extends Activity

Answer 2

You have to write

super.onCreateView(inflater, container, savedInstanceState); 

in your onCreateView method.

Answer 3

<fragment
    android:name="com.febro.myfragmenttest.ListFragment"
    android:id="@+id/listFragment"
    android:layout_width="250dp"
    android:layout_height="match_parent"
    android:layout_marginTop="?android:attr/actionBarSize"
    class="com.febro.myfragmenttest.ListFragment" ></fragment>

In this tag, you have both android:name and class set to the same thing. Since these map to the same thing, you should only use one. This is why this appeared in the stack trace:

java.lang.IllegalArgumentException: Binary XML file line #6: *Duplicate id* ....

In the Fragment android guide, they use these interchangeably for the same purpose.

Answer 4

I've run into the same error (different implementation). The underlying cause was because the View returned in the inflated fragment class (i.e. returned from the fragment's onCreateView() method) is invalid or you did not implement the onCreateView method itself.

In your case, check the view you're returning in com.febro.myfragmenttest.ListFragment and verify that it's valid. I'd suggest setting a breakpoint in the onCreateView method.

Hope this helps.
