Question

是否可以动态更改活动程序的android:noHistory属性值？

或许还有另一种方法可以做我想要的。我有一个QuickContactBadges活动...我希望它在弹出QuickContact后关闭活动，这就是我打开noHistory的原因，但活动也会启动配置活动。我不希望它从该活动回来时关闭（相反它应该刷新，如果我可以阻止它关闭，我可以这样做。）

您可以使用默认布尔值true作为活动onPause()方法中的触发器，告诉您是否要调用finish()。如果用户到达调用Configuration Activity的Activity部分，请将boolean设置为false，这样Activity就不会完成也不会从堆栈中删除。
