ClassCastException preventing PullToRefreshListView from inflating

[dregre]

I get the following error message when using your library:

10-28 23:39:06.536: E/AndroidRuntime(4486): Caused by: java.lang.ClassCastException: com.actionbarsherlock.internal.widget.ActionBarView$HomeView cannot be cast to android.widget.LinearLayout
10-28 23:39:06.536: E/AndroidRuntime(4486):     at eu.erikw.PullToRefreshListView.init(PullToRefreshListView.java:241)
10-28 23:39:06.536: E/AndroidRuntime(4486):     at eu.erikw.PullToRefreshListView.<init>(PullToRefreshListView.java:113)

How I got the error

I put a PullToRefreshListView in a layout XML called home.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="vertical" >

    <eu.erikw.PullToRefreshListView
        android:id="@+id/listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

I inflated this XML in a fragment called Home.java, which, in turn, I attached to a SherlockActivity (from the open-source library ActionBarSherlock) called MainActivity.java:

Home.java

public class Home extends Fragment {
    private PullToRefreshListView l;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        // Layout
        View v = inflater.inflate(R.layout.home, container, false); 
        l = (PullToRefreshListView) v.findViewById(R.id.listview);

        //Return
        return v;
    }
}

MainActivity.java

public class MainActivity extends Master {
    // Tabs listener
    private class TabsListener implements ActionBar.TabListener {
        private Fragment fragment;
        private String tag;

        public TabsListener(Fragment fragment, String tag) {
            this.fragment = fragment;
            this.tag = tag; 
        }

        @Override
        public void onTabReselected(Tab tab, FragmentTransaction ft) {
        }

        @Override
        public void onTabSelected(Tab tab, FragmentTransaction ft) {
            ft.replace(R.id.fragment_container, fragment, tag);
        }

        @Override
        public void onTabUnselected(Tab tab, FragmentTransaction ft) {
            ft.remove(fragment);
        }

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        // Setup
        super.onCreate(savedInstanceState);

        // Assignments
        context = getApplicationContext();

        // Layout
        getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        getSupportActionBar().setDisplayHomeAsUpEnabled(false);
        setContentView(R.layout.activity_main);

        Fragment fHome;
        if((fHome = getSupportFragmentManager().findFragmentByTag(HOME)) == null) fHome = new Home();

        ActionBar.Tab tab = getSupportActionBar().newTab();
        tab.setIcon(R.drawable.home);
        tab.setContentDescription("Home");
        tab.setTabListener(new TabsListener(
            fHome,
            "hom"
            ));
        getSupportActionBar().addTab(tab, false);
        }
}

Other potentially relevant info

I cloned your GitHub, imported the project into Android, then added it as a library to my own project. I made no modifications to your code.
