如何使 ListView 的页眉或页脚不可点击 [英] How to make the header or footer of a ListView not clickable

问题描述

我通过使用方法 setHeaderView() 和 setFooterView() 和 ListView 向 ListView 添加页脚和页眉视图代码>ViewInflater.这很好用.

I'm adding a footer and header view to a ListView by using the methods setHeaderView() and setFooterView() and a ViewInflater. That works quite well.

但是如何防止页眉或页脚视图触发 onListItemClick 事件?当然我可以捕获事件并检查它是来自页眉还是页脚，但这只能解决问题的一部分，因为单击时页眉和页脚仍然处于焦点状态.

But how could I prevent the header or footer view from firing onListItemClick events? Of course I can catch the event and check whether it came from a header or footer, but this only solves one part of the problem, as header and footer got still focused when clicked.

推荐答案

只需使用 ListView#addHeaderView(View v, Object data, boolean isSelectable); 和匹配的 addFooter() 方法.

Simply use the ListView#addHeaderView(View v, Object data, boolean isSelectable); and matching addFooter() method.

Object data参数的用途.

The purpose of Object data parameter.

ListView 源代码将 data 参数描述为:

The ListView source code describes the data parameter as:

支持视图的数据.这是从 ListAdapter#getItem(int) 返回的.

The data backing the view. This is returned from ListAdapter#getItem(int).

这意味着如果我使用 listView.getAdapter().getItem(0); 它将从我们的头返回 data 对象.

Which means if I use listView.getAdapter().getItem(0); it will return the data Object from our header.

我会用一个例子来详细说明:

I'll elaborate this with an example:

listView = (ListView) findViewById(R.id.list);
String[] array = new String[] {"one", "two", "three"};
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, array);

接下来让我们添加一个标题并设置适配器:

Next let's add a header and set the adapter:

listView.addHeaderView(view, "Potato", false);
listView.setAdapter(adapter);

稍后如果我们问:

Log.v("ListAdapter", listView.getAdapter().getItem(0));  // output: "Potato" 
Log.v("ArrayAdapter", adapter.getItem(0));               // output: "one"
