可以使用处理程序及其postDelayed方法在指定超时后更改视图。处理程序类是有文档记录的。logcat显示的错误是android系统在splash布局中找不到您的playbutton 看起来您正在尝试在AndroidManifest.xml中定义按钮。您应该在布局中定义它们，如下所述： 如果playbutton和settingsbutton是实际活动，我建议将它们资本化以匹配java约定。 您应该删除：

对不起？？我仍然需要帮助。我不允许在论坛上寻求帮助吗？对不起，我不想听起来粗鲁，我也不想违反规则，但是如果我找不到问题的答案，为什么我不能发布一些我仍然有问题的东西呢？在得到答案后，你可以做一段时间，而不是发布每次跑步的结果编译？不管你的船怎么漂，先生。沉没的不是我的船。
