ActionBarActivity of "android-support-v7-appcompat" and ListActivity in Same activity

Question

How to use ActionBarActivity of "android-support-v7-appcompat" in the activity which Extends the ListActivity.

For Example I have an Activity

public class xxxxxListActivity
  extends ListActivity implements OnItemSelectedListener  { 
  // ...................
} 

In the above activity i want to use "ActionBarActivity" but as java dosent support multiple inheritance I am not able to get it working.

Here's an implementation of ActionBarListActivity:

public abstract class ActionBarListActivity extends ActionBarActivity {

private ListView mListView;

protected ListView getListView() {
    if (mListView == null) {
        mListView = (ListView) findViewById(android.R.id.list);
    }
    return mListView;
}

protected void setListAdapter(ListAdapter adapter) {
    getListView().setAdapter(adapter);
}

protected ListAdapter getListAdapter() {
    ListAdapter adapter = getListView().getAdapter();
    if (adapter instanceof HeaderViewListAdapter) {
        return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
    } else {
        return adapter;
    }
}
}

Just like regular ListActivity, you'll need a layout that contains a ListView with the ID android.R.id.list ("@android:id/list" in XML).

The spiel in getListAdapter() is to handle cases where header views have been added to the ListView. Seems like ListView sets its own adapter to a HeaderViewListAdapter, so we have to try and get the wrapped adapter to prevent casting errors.

Edit: Try adding this function to satisfy the need for onListItemClick:

protected void onListItemClick(ListView lv, View v, int position, long id) {
    getListView().getOnItemClickListener().onItemClick(lv, v, position, id);
}
