Themes

A theme is style that’s applied to your entire app, activity or view hierarchy rather than an individual view. By default, Sendbird UIKit for Android provides two themes: Light and Dark. Customized themes that fit your brand identity can also be created by changing the style and color set.

Setup the default theme

UIKit for Android's Light or Dark theme can be applied using the SendBirdUIKit.setDefaultThemeMode() method.

Light theme

This is the default theme for UIKit if another theme hasn’t been specified.

SendBirdUIKit.setDefaultThemeMode(SendBirdUIKit.ThemeMode.Light);

Dark theme

The Dark theme can be applied as below:

SendBirdUIKit.setDefaultThemeMode(SendBirdUIKit.ThemeMode.Dark);

StyleSet

StyleSet is the list of styles provided by UIKit. Customizing the style of channel list items is straightforward: Simply inherit the UIKit-defined styles, then override the res/values/styles.xml file from the list below. For example, the ChannelPreview theme can be changed by overriding the Widget.SendBird.ChannelPreview.

Note : To apply our Dark theme, create a res/values/styles_dark.xml file and then add .Dark to the UIKit-defined style names.
