What I want to achie

Answer 1

Using ActionBarSherlock the MultiChoiceModeListener used in Luksprog´s answer is not yet available if you want to support API level < 11.

A workaround is to use the onItemClickListener.

List setup:

listView = (ListView) timeline.findViewById(android.R.id.list);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setItemsCanFocus(false);
listView.setAdapter(new ListAdapter(getActivity(), R.layout.cleaning_list_item, items));

Listener of ListFragment or ListActivity:

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    SparseBooleanArray checked = listView.getCheckedItemPositions();
    boolean hasCheckedElement = false;
    for (int i = 0; i < checked.size() && !hasCheckedElement; i++) {
        hasCheckedElement = checked.valueAt(i);
    }

    if (hasCheckedElement) {
        if (mMode == null) {
            mMode = ((SherlockFragmentActivity) getActivity()).startActionMode(new MyActionMode());
            mMode.invalidate();
        } else {
            mMode.invalidate();
        }
    } else {
        if (mMode != null) {
            mMode.finish();
        }
    }
}

Where MyActionMode is an implementation of ActionMode.Callback:

private final class MyActionMode implements ActionMode.Callback { /* ... */ }
