android - 为 ListView 设置选择器时出现异常

Question

我正在尝试像这样设置一个 ListView 选择器:

fileList.setSelector(android.R.layout.simple_list_item_checked);

然后我得到:

知道为什么会这样吗？

Answer 1

您正在尝试将来自 SDK 的 layout 资源设置为选择器(该布局文件特别是一个简单的 CheckedTextView元素)，这显然无法正常工作，因为它需要一个drawable 资源。您很可能想要一个drawable:

android.R.drawable.something

(例如:android.R.drawable.list_selector_background，默认选择器)
