2018+ UPDATE Today, the findPreference method is depricated. So, to achieve this, just override the onPreferenceTreeClick method in your Preference fragment. For example:

public class MySettingsFragment extends PreferenceFragment {

    @Override
    public boolean onPreferenceTreeClick (PreferenceScreen preferenceScreen,
                                          Preference preference)
    {
        String key = preference.getKey();
        if(key.equals("someKey")){
            // do your work
            return true;
        }
        return false;
    }
}

Furthermore, if you need to handle a click inside particular preference element (e.g. ListPreference), you should register the setOnPreferenceChangeListener inside the onCreate method of the MySettingsFragment:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Load the preferences from an XML resource
    addPreferencesFromResource(R.xml.preferences);

    // register listener
    final Preference prefList = findPreference("key");
    prefList.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
        public boolean onPreferenceChange(Preference preference, Object value) {
            System.out.println("Selected: " + value);
            return true;
        }
    });
}
