![]() #Android studio themes androidLet me know what you think about new Android features in the comments below.This is because a view only knows about its own attributes Button isn’t aware of the colorPrimary attribute so it’s ignored.Ī view gets the view attributes from the layout file or the style attribute. In most scenarios, it’s all about arranging the dark mode set of resources to the appropriate folders. According to slashgear article using Google Maps dark mode on maximum brightness reduces battery usage by 63% compared to the light version which I think is a really significant benefit.Īs a developer, I love the simplicity of adding support for dark mode in the application. Dark pixels are effectively switched off so dark content uses less battery. More and more devices are equipped with OLED screens where pixels are lit individually. SummaryĪs a user, I personally love it when an application supports night mode because it makes applications more comfortable to use in low-light environments. #Android studio themes codeWorking code can be found in the following repository here. Val currentNightMode = configuration.uiMode and Configuration.UI_MODE_NIGHT_MASKĬonfiguration.UI_MODE_NIGHT_NO -> // Night mode is active If there is some logic that we want to execute at runtime depending on the current theme, it’s possible to do so with the code snippet below: To see how the layout looks in dark mode, all you need to do is to check the night option in the preview settings as shown below: Values/app_collors.xml: course, the same effect can be achieved with theme-specific styles.xml files, but I think that this approach is a little bit clearer in this scenario. For the colors I like approach, where I define generic color names in colors.xml: Īnd then I keep theme-specific colors in different files: In my example, I used dark mode-specific folders only for drawable and values. Below, I have shown how dark mode-specific resources look in Android Studio: So as you can see, nearly every resource can be different in Dark theme. The next step is to put dark mode-specific resources in a folder with the -night suffix. The first one is to replace the parent theme in styles.xml with when the application is using AppCompat and when using the MaterialComponents theme. To take advantage of Dark theme in an app, you need to take a few simple steps: If both the default and local night modes are set to this value, then the default value of MODE_NIGHT_FOLLOW_SYSTEM is applied. This is primarily used with setLocalNightMode(int), to allow the default night mode to be used. The default on all systems is MODE_NIGHT_UNSPECIFIED, but as we can read in the documentation:Īn unspecified mode for night mode. To set a specific mode, all we need to do is to call one static method tDefaultNightMode(mode) with one of the modes. #Android studio themes for androidFor Android 10 or newer -> MODE_NIGHT_FOLLOW_SYSTEM.For Android 9 or older -> MODE_NIGHT_AUTO_BATTERY.Since MODE_NIGHT_FOLLOW_SYSTEM is the only option that does not take effect in Android 9 or older, we can freely use other ones.MODE_NIGHT_FOLLOW_SYSTEM -> Turns on Dark theme when Dark theme toggle is turned on in settings.MODE_NIGHT_AUTO_BATTERY -> Turns on Dark theme when battery optimization is turned on in settings.MODE_NIGHT_YES -> Forces app to turn on Dark theme.MODE_NIGHT_NO -> Forces app to turn on Light theme.MODE_NIGHT_UNSPECIFIED -> Unspecified setting.While Dark theme was introduced in Android 10, older devices can take advantage of it! Wouldn’t it be great to make the system and apps dark with a single click or even have it turned on automatically? Well, Android 10 makes it much more user-friendly both for the end-user and the developer. Some apps support more eye-friendly themes at night, but every application needs to be configured separately. Most likely everyone would agree that using very bright applications at night is uncomfortable. In my opinion, one of the most interesting is the Dark theme. Android 10 brings us lots of new features. ![]()
