我有一個列表視圖,在Android的某些版本中工作正常,但在棒棒糖列表視圖不顯示所有信息(只有1個字符串5)。在我的應用我只是AppCompatActivity的延伸的活動,在這裏我的適配器ListView棒棒糖不顯示所有信息

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; 
    } 
} 

這裏MI XML文件:home_promo_item

在棒棒糖中,我們需要設置字符串的顏色,因爲它會自動將其設置爲白色,因此我無法看到來自對象的所有字符串。

對不起,我的英語,它不是我的母語

郵政home_promo_item,可能是你的LinearLayout是水平,而它應該是VERTICAL來顯示ListView中的行。
