I have an Android application where I allow users to switch between themes at runtime. Switching a theme is easy but the theme isn't applied until the activity is recreated. I found a way to apply the theme to current activity but if the user presses back button previous screens still have the old theme. How can I change theme for those activities?

推荐答案

在运行时动态，调用setTheme（）在活动的onCreate（）方法，调用的setContentView（）之前。要更改主题，你只需要重新启动您的活动。

Dynamically at runtime, call setTheme() in your activity's onCreate() method, before calling setContentView(). To change the theme, you simply need to restart your activity.
