Question

我有一个列表视图在某些版本的android中工作正常，但在棒棒糖中，列表视图不显示所有信息（只有1个字符串为5）。在我的应用程序中，我只有一个扩展AppCompatActivity的活动，这里是我的适配器

    public class PromoAdapter extends ArrayAdapter {


    private Context context;
    private ArrayList<PromoObject> originalData = null;
    public PromoAdapter(Context context, ArrayList<PromoObject> listArray) {
        super(context, R.layout.home_promo_item);
        this.context = context;
        this.originalData = listArray ;
    }

    public static class Row
    {
        public TextView labelPromo;
        public ImageView imagePromo;
        public TextView titlePromo;
        public TextView daysPromo;
        public TextView schedulePromo;
    }

    @Override
    public int getCount() {
        return  originalData.size();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View rowView = convertView;
        // reuse views
        if (rowView == null) {
            LayoutInflater inflater = LayoutInflater.from(context);
            rowView = inflater.inflate(R.layout.home_promo_item, null);
            // configure view holder
            Row viewHolder = new Row();

            viewHolder.labelPromo = (TextView) rowView.findViewById(R.id.label_promo);

            viewHolder.imagePromo = (ImageView) rowView.findViewById(R.id.logo_promo);

            viewHolder.titlePromo = (TextView) rowView.findViewById(R.id.title_promo);

            viewHolder.daysPromo = (TextView) rowView.findViewById(R.id.days_promo);

            viewHolder.schedulePromo = (TextView) rowView.findViewById(R.id.schedule_promo);

            rowView.setTag(viewHolder);
        }
        Row holder = (Row) rowView.getTag();
        PromoObject itm = originalData.get(position);
        holder.labelPromo.setText(itm.getPromoValue());
        holder.imagePromo.setImageResource(R.drawable.ic_pizzahut);
        holder.titlePromo.setText(itm.getTitlePromo());
        holder.daysPromo.setText(itm.getDays());
        holder.schedulePromo.setText(itm.getSchedule());

        return rowView;
    }
}

这里是mi XML文件：home_promo_item

Answer 1

在棒棒糖中，我们需要设置字符串的颜色，因为它会自动将其设置为白色，因此我无法看到对象中的所有字符串。

对不起我的英语，这不是我的母语

Answer 2

发布home_promo_item，可能你的LinearLayout是HORIZONTAl，而它应该是VERTICAL来显示ListView中的行。

ListView Lollipop不显示所有信息
