Question

我有一个arrayadapter，它填充了4个文本字段。在getView方法中，它尝试使用值填充文本字段。我得到错误android.content.res.Resources $ NotFoundException：字符串资源ID＃0x11。你可以指导它需要纠正的地方。

以下是ArrayAdapter代码

public class AdapterTicketList extends ArrayAdapter<POJO_Ticket> {
Context context;
ArrayList<POJO_Ticket> ticketArray;
LayoutInflater vi;

public AdapterTicketList(Context context , ArrayList<POJO_Ticket> ticketArray) {    
    super(context, 0, ticketArray );    
    this.ticketArray = new ArrayList<POJO_Ticket>();    
    this.ticketArray.addAll(ticketArray);  
    this.context =context;

    vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
    }  

private class ViewHolder {
    TextView tvTicketID;  
    TextView tvCreationHour;  
    TextView tvTableNumber;     
    TextView tvAmount;    
    } 

public View getView(final int position, View convertView, ViewGroup parent) {      
    ViewHolder holder;    
    holder = new ViewHolder();
    if (convertView == null) {                   
        convertView = vi.inflate(R.layout.rowticket,  null);  
        holder.tvTicketID = (TextView) convertView.findViewById(R.id.tvTicketID); 
        holder.tvCreationHour = (TextView) convertView.findViewById(R.id.tvCreationHour); 
        holder.tvTableNumber = (TextView) convertView.findViewById(R.id.tvTableNumber); 
        holder.tvAmount = (TextView) convertView.findViewById(R.id.tvQuantity);  
        convertView.setTag(holder); 
    } else {
        holder = (ViewHolder) convertView.getTag();  
    }       
    Ticket ticket =ticketArray.get(position).getTicketObject();

    Log.i("AdapterTicketList"," ticket id : " + ticket.getId()); 
    holder.tvTicketID.setText(String.valueOf(ticket.getId())) ;  
    holder.tvCreationHour.setText(String.valueOf(ticket.getCreationHour())) ;  
    holder.tvTableNumber.setText(String.valueOf(ticket.getTableNumber())) ;   
    holder.tvAmount.setText( String.valueOf((ticket.getTotalAmount())))  ; 
    return convertView; 
    }

}

Answer 1

这一行是正确的，因为您将数值转换为字符串：

holder.tvAmount.setText(Double.toString(ticketArray.get(position).getTicketObject().getTotalAmount())) ;

由于它们似乎在获取数值，因此存在潜在的问题：

holder.tvTicketID.setText(ticketArray.get(position).getTicketObject().getId()) ;  
holder.tvCreationHour.setText(ticketArray.get(position).getTicketObject().getCreationHour()) ;  
holder.tvTableNumber.setText(ticketArray.get(position).getTicketObject().getTableNumber()) ;

解决方案：必须将字符串或相应的R.string.xxx整数传递给setText()。

所以使用：

holder.tvTicketID.setText(String.valueOf(ticketArray.get(position).getTicketObject().getId()));
// etc

（您还应该考虑将ticketArray.get(position).getTicketObject()保存在局部变量中，而不是重复获取它。）
