Я получаю это исключение:

но проблема в том, что я не могу найти корень проблемы. Где именно и что это значит?

И почему виджет, у меня нет никакого виджета!

КОД:

Не уверен, если здесь:

public class MyListPreference extends ListPreference {

    public MyListPreference(Context context) {
        super(context);
    }

    public MyListPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected View onCreateDialogView() {
        TextView dialogTitle = (TextView)super.onCreateDialogView();

        if (dialogTitle != null) {
            // Dialog
            dialogTitle.setBackgroundColor(getContext().getResources().getColor(R.color.category_background));
            dialogTitle.setPadding(10, 4, 4, 4);

            // Text
            dialogTitle.setTextSize(14);
            dialogTitle.setTypeface(null, Typeface.BOLD);
            dialogTitle.setTextColor(getContext().getResources().getColor(R.color.actionbar_background));

            dialogTitle.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
        }
        return dialogTitle;
    }
}
