Configure and style incoming, outgoing, and specific message bubbles in your Android UI Kit.
When to use this
You want to customize the look of incoming and outgoing message bubbles.
You need different styles for text, image, audio, video, file, sticker, poll, or collaborative bubbles.
You want to style call action bubbles, delete bubbles, or AI assistant bubbles.
You need to customize quoted reply previews.
You prefer centralized styling through res/values/themes.xml.
Prerequisites
CometChat UI Kit for Android is installed and initialized.
Your app theme extends CometChatTheme.DayNight.
You can edit res/values/themes.xml in your Android module.
You rebuild or sync Gradle after updating styles.
Quick start
Set up the global bubble hubs
Define CustomIncomingMessageBubbleStyle and CustomOutgoingMessageBubbleStyle in res/values/themes.xml and connect them to AppTheme.
Style a specific bubble type
Create a custom style for the bubble type (e.g., CustomIncomingTextBubbleStyle) and link it inside the hub style.
Build and verify
Run the app, open a conversation, and confirm the bubble styling.
Message bubbles are the core visual element in chat applications. Customizing them allows you to create a consistent user experience that aligns with your app’s theme.
This guide covers how to style Base Message Bubbles (the container) and Specific Message Types (Text, Image, Audio, etc.). Customization options include adjusting the background color , text appearance , and bubble shape to differentiate between incoming and outgoing messages.
Styling Architecture
To style message bubbles effectively without duplicating code, understand this inheritance hierarchy.
All code in this guide belongs in res/values/themes.xml.
AppTheme : The root theme of your application.
Message Bubble Styles : Acts as a central hub for all incoming/outgoing message styles. Linked directly to the AppTheme.
Specific Bubble Styles : Targets specific message types (e.g., Text, Video, Audio). These are linked inside the Message Bubble Styles.
Global Setup
Define this once in your res/values/themes.xml. All subsequent custom bubble styles will be routed through these hubs.
<!-- 1. Central Hub for Incoming Messages -->
< style name = "CustomIncomingMessageBubbleStyle" parent = "CometChatIncomingMessageBubbleStyle" >
< item name = "cometchatMessageBubbleBackgroundColor" > #FEEDE1 </ item >
<!-- Specific Incoming styles (Text, Image, etc.) will be added here -->
</ style >
<!-- 2. Central Hub for Outgoing Messages -->
< style name = "CustomOutgoingMessageBubbleStyle" parent = "CometChatOutgoingMessageBubbleStyle" >
< item name = "cometchatMessageBubbleBackgroundColor" > #F76808 </ item >
<!-- Specific Outgoing styles (Text, Image, etc.) will be added here -->
</ style >
<!-- 3. Connect the Hubs to your App Theme -->
< style name = "AppTheme" parent = "CometChatTheme.DayNight" >
< item name = "cometchatIncomingMessageBubbleStyle" > @style/CustomIncomingMessageBubbleStyle </ item >
< item name = "cometchatOutgoingMessageBubbleStyle" > @style/CustomOutgoingMessageBubbleStyle </ item >
</ style >
