问题 I have an Android app that has a default theme of Holo.Light but I want to change it to Theme.Black.I tried to do this by changing the style tag in the manifest android:theme="@style/AppTheme" to Theme.Black but it cannot be found.Is there extra steps I have to take in changing the theme? 回答1: Actually you should define your styles in res/values/styles.xml . I guess now you've got the following configuration: <style name="AppBaseTheme" parent="android:Theme.Holo.Light"/> <style name="AppTheme

问题 Microsoft Windows lets programmers draw GUI elements using the look and feel of the current theme using functions like DrawThemeBackground and DrawThemeText. The elements are specified by Class, Part, and State, as described at the Parts and States page at MSDN. Unfortunately, the page is not very informative (at all!).

问题 In Firefox 67, one can use media queries to detect user preference on light or dark theme. In my version of Firefox (under Ubuntu), it seems that my preference is light theme. That is, the following CSS gives a blue background: @media (prefers-color-scheme: light) { :root {} body { background-color: blue; } } How can I change my Firefox preferences so that prefers-color-scheme: dark evaluates to true? I found an add-on that seems to do the trick, but I must be doing something wrong with my

问题 I deleted the chosen default theme in WebSphere Portal 6.1 using the administration pages. Now the portal is themeless. More importantly, the theme selection page in the administration section can no longer be displayed. How can I set the default theme "externally" (i.e. manually, without the administration pages)? 回答1: You will need to correct this with xmlaccess.
