How to add a "long click listener" to a Preference?

In the event that the link dies, here is the main body of the post at that link. Note: I did not author anything below.

The built-in Preference class has a method to receive clicks, onClick, but no method to receive long clicks. In my current project, I actually have a need for this, and found a way to implement it.

PreferenceActivity is actually a ListActivity, with a special adapter behind the scenes. The usual (not long) clicks are processed by using the usual ListView mechanism, setOnItemClickListener. The code to set this up is in PreferenceScreen:

public final class PreferenceScreen extends PreferenceGroup implements AdapterView.OnItemClickListener.... {
    public void bind(ListView listView) {
        listView.setOnItemClickListener(this);
        listView.setAdapter(getRootAdapter());

        onAttachedToActivity();
    }

    public void onItemClick(AdapterView parent, View view, int position, long id) {
        Object item = getRootAdapter().getItem(position);
        if (!(item instanceof Preference)) return;
                     
        final Preference preference = (Preference) item;
        preference.performClick(this);
    }
}

It would be really easy to subclass PreferenceScreen and override bind to add a long-item-click listener to the list view, except this class is final. Because of this, I ended up adding the following code into my PreferenceActivity subclass:

public class BlahBlahActivity extends PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
 
        addPreferencesFromResource(R.xml.account_options_prefs);
 
        ListView listView = getListView();
        listView.setOnItemLongClickListener(new OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                ListView listView = (ListView) parent;
                ListAdapter listAdapter = listView.getAdapter();
                Object obj = listAdapter.getItem(position);
                if (obj != null && obj instanceof View.OnLongClickListener) {
                    View.OnLongClickListener longListener = (View.OnLongClickListener) obj;
                    return longListener.onLongClick(view);
                }
                return false;
            }
        });
    }
}

Now I can have a Preference subclass that implements View.OnLongClickListener, which is automatically invoked for long clicks:

public class BlahBlahPreference extends CheckBoxPreference implements View.OnLongClickListener {
    @Override
    public boolean onLongClick(View v) {
        // Do something for long click
        return true;
    }
}
