android - ArrayAdapter IndexOutOfBoundsException异常

Question

我正在尝试通过 onclick 操作从 ListView 中删除一个项目。但我收到 arrayindexoutofbound 异常。我从 11 大小的数组中删除了项目，但它仍在尝试获取 11. 项目。

        public void onClick(View v) {
            data.remove(getItemIndexByID(filteredData.get(position).getID()));
            filteredData.remove(position);      
            notifyDataSetChanged();

            flipMenu(lastHolder, 1);
            showPopup("Item Deleted"); 


        }

Answer 1

我注意到 ArrayAdapter 的 getcount 方法总是返回相同的值，我像这样覆盖了 getCount() 方法，它有效。

@Override
public int getCount() {
    return filteredData.size();
}
