java - 如何使列表页眉和页脚不可点击？

Question

我有一个带有页脚和页眉的列表。我添加了 onLongClick 以从列表中删除项目。当我长按标题时，它会从列表中删除第一项。当我单击最后一个项目或页脚时，应用程序将崩溃 - 项目超出范围。

Can I make footer and header not clickable? or how should i count item in adapter? or is there some other way to baypass it?

Removing items:

list.setOnItemLongClickListener(new OnItemLongClickListener() {
        public boolean onItemLongClick(AdapterView<?> parent, View v,
                int position, long id) {
            // Delete Item from List

            ShoppingItem simpleItem = null;

            if (shoppingListApplication.getAdapter().getCount() > 0) {
                simpleItem = (ShoppingItem) shoppingListApplication
                        .getAdapter().getItem(position);
                removeShoppingItem(simpleItem,
                        shoppingListApplication.getAdapter());

            }

您必须使用addHeaderView (View v, Object data, boolean isSelectable)和 addFooterView (View v, Object data, boolean isSelectable)使ListView的页眉和页脚不可点击。

只需传递 false 代替页眉和页脚的 isSelectable。

伪代码，

listview.addHeaderView(header_view, null, false);
listview.addFooterView(footer_view, null, false);
