我目前正在开发一个 Android 应用程序，虽然在 Jelly Bean 模拟器上一切正常，但在 2.2 模拟器上出现以下错误：

据我所知，我没有使用任何 Jelly Bean 特定功能，也不知道我遇到了什么错误。我确实有一个自定义适配器，但我没有做太多，我只更改了几个文本视图。

将您的适配器更改为以下内容：

public class MethodAdapter extends ArrayAdapter<Method> {

    LayoutInflater inflater;

    public MethodAdapter(Context context, int layout, int field, ArrayList<Method> methodsList) {
        super(context, layout, field, methodsList);
            inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER);
    }

    class ViewHolder {
        TextView bellName;
        TextView bellType;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder = null;
        if (convertView == null) {
                convertView = inflater.inflate(R.layout.your_item_layout, null);
                holder = new ViewHolder();
                holder.bellName = (TextView) row.findViewById(R.id.bellName);
            holder.bellType = (TextView) row.findViewById(R.id.bellType);
                convertView.addTag(holder);
            } else {
                holder = (ViewHolder)convertView.getTag();
            }

        Method m = getItem(position);

        holder.bellName.setText(m.getName());
        holder.bellType.setText(m.getSuffix());
        return convertView;
    }
}

Ps.：我没有编译这段代码。先检查一下......
