滚动时多个布局的ListView崩溃

Question

我有一个自定义适配器来显示无聊的东西列表.现在,我想添加一个带有摘要(Resumen)的最后一项.

我使用两个布局和两个视图,它有点工作

当我滚动回第一个项目时问题开始了.当"Resumen"项目消失(最后一个)时,活动崩溃.

让我告诉你适配器代码(相关的行)

public class AdapterListaDeudaCliente extends BaseAdapter
{
    final private int VIEW_TYPES = 2;
    final private int TIPO_FACTURA = 1;
    final private int TIPO_RESUMEN = 2;

    public int getViewTypeCount()
    {
        return VIEW_TYPES; 
    }

    public int getItemViewType(int position) 
    {
        if(position%2==0)
            return TIPO_RESUMEN;
        else
            return TIPO_FACTURA;
    }

    public int getCount()
    {
        return data.length;
    }

    public View getView(int position, View convertView, ViewGroup parent)
    {
         int tipo = getItemViewType(position);
            switch(tipo)
            {
                case TIPO_FACTURA: convertView = layoutInflater.inflate(R.layout.elemento_deuda_basico, null);
                                                 break;
                case TIPO_RESUMEN: convertView = layoutInflater.inflate(R.layout.elemento_deuda_resumen, null);
                                                 break;
            }
        return convertView;
    }
}

最后,崩溃日志:

如果这段代码根本不起作用,我会怀疑这是显而易见的,但只有在摘要视图消失时崩溃...我无法检测到失败.

谢谢!!

我更改了适配器和布局.每个布局只由一个纯文本视图组成.滚动listView时应用程序崩溃.

这很奇怪.

更多信息:我正在使用API​​级别8和兼容包.活动是FragmentActivity,我在ViewPager中使用listView.

Answer 1

这很奇怪......但问题在于:

final private int VIEW_TYPES = 2;
final private int TIPO_FACTURA = 1;
final private int TIPO_RESUMEN = 2;

我改成了:

final private int VIEW_TYPES = 2;
final private int TIPO_FACTURA = 0;
final private int TIPO_RESUMEN = 1;

现在它有效......

就个人而言,我觉得没有意义......为什么视图类型应该从零开始？
