    this.context = context;
    officialKanals = officiallar;
    normalKanals = normaller;

@Override

}

public View getView(int position, View convertView, ViewGroup viewGroup) {
    KanalHolder holder = null;

        }

        convertView.setTag(holder);
    }else{
        holder = (KanalHolder)convertView.getTag();
    }
    //holder.tv1.setText(normalKanals.get(position).getKanaladi());
        holder.image1.setImageResource(R.mipmap.aliprof);
    return convertView;
}


static class KanalHolder{
    public ImageView image1;
    public TextView tv1 , tv2;
    public Button buton1;
}
}

它会出现如下错误：

我知道它说我试图在索引2中获取对象，但没有索引2（0和1）。但我的数组大小是官方用户的10.5对象。 5为普通人。哪里弄错了？

Answer 1

问题出在您的项目视图类型中。

Adapter.getItemViewType(int)

注意：整数必须在0到getViewTypeCount（） - 1
的范围内

将OFFICIAL_KANAL更改为0，将NORMAL_KANAL更改为1.

数组索引超出了listview的范围
