Override click in android preference setting

Question

In my application, I would like to show a warning when using a specific preference in my application. I tried using PreferenceActivity.onPreferenceTreeClick and onPreferenceClickListener, but none of them work. The following is an example below. Can someone shed some light on this, please?

@Override
protected void onCreate(Bundle saved) {

    super.onCreate(saved);
    addPreferencesFromResource(R.xml.prefs);
    Preference gridview = findPreference("fcngrid");
    gridview.setOnPreferenceClickListener(overrider);

}

public OnPreferenceClickListener overrider = new OnPreferenceClickListener() {

    public boolean onPreferenceClick(Preference pref) {

        if (pref.getTitle() == "Default as grid")
            showDialog(0);

        return false;
    }

};

protected Dialog onCreateDialog(int id) {

    AlertDialog.Builder b = new AlertDialog.Builder(this);
    b.setTitle("Warning")
     .setMessage("Unfortunately, this feature is currently unstable, and will be" +
             " fixed soon.")
     .setPositiveButton("OK", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {

            dialog.cancel();

        }

     });

    return b.create();

}

Do not worry, use pref.getTitle().equals("Default as grid")works great.
