【问题描述】：

我有一个用于 listView 的自定义适配器。当我尝试膨胀一些 View 时，它会引发异常。这是我的getView() 代码：

public View getView(int position, View convertView, ViewGroup parent){
    View row = mInflater.inflate(R.layout.items_list_element, parent);
    CheckBox cb = (CheckBox)row.findViewById(R.id.gotItCheckBox);
    String checked = String.valueOf(cb.isChecked());
    return row;
}

行View row = mInflater.inflate(R.layout.items_list_element, parent);抛出这个：

有人知道怎么回事吗？

编辑：我确保 mInflater 不为空。

【解决方案1】：

改变

View row = mInflater.inflate(R.layout.items_list_element, parent);

与

View row = mInflater.inflate(R.layout.items_list_element, parent, false);

【解决方案2】：

试试下面的代码：-

View row=null;
                if (row == null) 
                {
                    LayoutInflater inflater = ((Activity) context).getLayoutInflater();
                    row = inflater.inflate(layoutResourceId, parent, false);
                }
