rk我在ICS上运行了上面的代码，一切正常。我想知道这对你是否有用。不管怎样，这对我不起作用。我的意思是，当我从列表中选择一个项目时，该项目不会保持“点亮”。它短暂地变成橙色，但随后又恢复为黑色。为什么不用上面的代码创建一个项目并运行它，看看它是否有效。您只需要上面的代码和清单。谢谢，稍后再试。我会让你知道事情的进展。为什么人们发布不起作用的答案？他们为他们工作吗？你什么意思不工作？我在ICS上运行了上面的代码，没问题。我想知道这对你是否有用。不管怎样，这对我不起作用。我的意思是，当我从列表中选择一个项目时，该项目不会保持“点亮”。它短暂地变成橙色，但随后又恢复为黑色。为什么不用上面的代码创建一个项目并运行它，看看它是否有效。您只需要上面的代码和清单。
