Question

我正在尝试像这样设置ListView选择器：

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

我得到了：

有关为何发生这种情况的任何想法？

Answer 1

您正在尝试将{{1>}中的布局资源设置为选择器（该布局文件特别是一个简单的SDK元素），这显然不会因为它需要一个 drawable 资源。您最有可能想要 drawable ：

CheckedTextView

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

为ListView设置选择器时出现异常
