public class ConfigActivity extends PreferenceActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);     
    addPreferencesFromResource(R.xml.preference);
    findViewById(android.R.id.list).setBackgroundColor(getResources().getColor(R.color.gray));
}
