当我在LiveActivity上单击硬件后退按钮时，它返回到MainActivity但我的幻灯片菜单也打开了，当我点击硬件后退按钮时如何隐藏它们？

Answer 1

如果您碰巧使用https://github.com/jfeinstein10/SlidingMenu，我建议您切换到NavigationDrawer，因为不再维护SlidingMenu并且还有尚未解决的错误。如果您坚持使用该库，我建议您在通过调用

转到LiveActivity之前关闭菜单

if (menu.isMenuShowing()) {
    menu.showContent();
}

Answer 2

您可以通过以下方式解决此问题：

将onBackPressed移至全局变量
在您想要的活动中覆盖方法@Override public void onBackPressed() { super.onBackPressed(); if (menu.isMenuShowing()) { menu.toggle(); } }单击后退硬键以关闭滑动菜单，如下面的代码： .replace()

单击硬件后退按钮时，无法隐藏侧面菜单
