Я использую адаптеры курсора для заполнения моего listview, но когда я меняю курсор, это выдает ошибку java.lang.Исключение ArrayIndexOutOfBoundsException

import me.nkkumawat.chatzzz.R;


public class ChatAdapter extends CursorAdapter {

    private Cursor cursor;

    public ChatAdapter(Context context, Cursor cursor) {
        super(context, cursor, 0);
        this.cursor = cursor;
    }
    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        return LayoutInflater.from(context).inflate(R.layout.list_chat, parent, false);
    }

    @Override

        TextView tv_message = (TextView)view.findViewById(R.id.chat_message);
        TextView tv_message_from = (TextView)view.findViewById(R.id.message_from);

        String body = cursor.getString(1);
        tv_message_from.setText(cursor.getString(2));
        tv_message.setText(body);
    }

    @Override

        return getCount();
    }

Я хочу предотвратить состояние listview. Если я удаляю метод getItemViewType, то при прокрутке listview изменяется и выглядит плохо. Я хочу предотвратить состояние Listview.
Пожалуйста, помогите и заранее благодарим.
