java - 如何在 ArrayAdapter 上设置父背景

Question

我正在构建一个应用程序，在阵列适配器上设置背景时遇到一些困难，希望有人可以提供帮助!

公共(public)类ListAdapter扩展ArrayAdapter {

    // List context
    private final Context context;
    // List values
    private final List<RssItem> items;

    public ListAdapter(Context context, List<RssItem> items) {
        // Set the layout for each item
        super(context, R.layout.item, items);
        this.context = context;
        this.items = items;


    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {


        // Build each element of the list


        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);


        View rowView = inflater.inflate(R.layout.item, parent, false);


        // Populate each layout element with the data from the items list
        TextView itemPos = (TextView) rowView.findViewById(R.id.position_aa);
        itemPos.setText(items.get(position).getPosition());

        // Populate each layout element with the data from the items list
        TextView itemTitle = (TextView) rowView.findViewById(R.id.textViewTitle);
        itemTitle.setText(items.get(position).getTitle());


        TextView itemPublishDate = (TextView) rowView.findViewById(R.id.textViewPublishDate);
        itemPublishDate.setText(items.get(position).getPublishDate());

        // Set the icon base on the post's category
        ImageView icon = (ImageView) rowView.findViewById(R.id.imageViewCategoryIcon);
        icon.setImageResource(CategoryMapper.getIconIdForCategory(items.get(position).getCategory()));


        return rowView;

    }
}

这是 item.xml

                            android:textColor="#555"
                            android:text="[PUB-DATE-GOES-HERE]"
                            android:textAppearance="?android:attr/textAppearanceSmall" />

                    </TableRow>

                    <TableRow
                        android:layout_width="wrap_content"

                    </TableRow>


                </TableLayout>

            </TableRow>

        </TableLayout>

    </LinearLayout>


</LinearLayout>

这里我通过列表适配器类将一些 rss 数据部署到 RowViews 中，但是如何设置父布局以便在滚动背景上进行固定？

提前致谢

P.S 我被困在这个问题上一天了......

将背景颜色设置为您的ListItem，例如

rowView.setBackgroundResource(R.color.yourcolor);
