DialogPreference constructor sets onPreferenceClickListener?

Question

I have set an onPreferenceClickListener on my subclass of DialogPreference like so:

public class SeekBarDialogPreference extends DialogPreference {
    ...
    public void show() {
        onClick();
    }
}


public class TopPage extends PreferenceActivity {
    ...
    SeekBarDialogPreference Foo = (SeekBarDialogPreference) findPreference("Foo");
    foo.setOnPreferenceClickListener(new OnPreferenceClickListener() {

        public boolean onPreferenceClick(Preference pref) {
            ((SeekBarDialogPreference) pref).show();
            return true;
        }
    });

When the SeekBarDialogPreference is clicked, showDialog() and onCreateDialogView() are called twice each. My question is does the DialogPreference constructor generate a click listener by default, making my code redundant?

Answer 1

Yes, it does. Publicizing onClick() is redundant. This leads me to question the credibility of this answer.
