How to filter state messages in a chatroom?

With the LikeMinds Chat SDK, you have full control over which state messages show up in a chatroom. Whether it’s join/leave notifications, system alerts, or other updates, you can decide what stays and what gets filtered out. This guide will walk you through the simple steps to customize message visibility, so your chatroom stays clean, relevant, and free from unnecessary distractions.

Prerequisites

1. LikeMinds Chat Android SDK: The SDK must be properly installed and initialized in your Android project. Refer to the installation guide if needed.

Steps to Filter State Messages in Chatroom

Step 1: Create List of States to filtered

First, define the list of state messages you want to filter using the ConversationState enum. This ensures only relevant messages appear in the chatroom, keeping conversations clean and focused.

Kotlin

val excludeConversationStates: List<ConversationState> = emptyList()

Java

List<ConversationState> excludeConversationStates = new ArrayList<>();

You can choose the states to filtered out using the below table

Enum	Type	Example
NORMAL	Normal message	Hey
FIRST_CONVERSATION	Chatroom first message	Tony Stark started this chatroom
MEMBER_JOINED_OPEN_CHATROOM	Member joins open chatroom	Tony Stark joined this chatroom
MEMBER_LEFT_OPEN_CHATROOM	Member leaves open chatroom	Tony Stark left this chatroom
MEMBER_ADDED_TO_CHATROOM	Member added in chatroom	Nick Fury added Tony Stark
MEMBER_LEFT_SECRET_CHATROOM	Member leaves secret chatroom	Tony Stark left this chatroom
MEMBER_REMOVED_FROM_CHATROOM	Member is removed from a chatroom	Nick Fury removed Tony Stark
POLL	Poll message	Nick Fury created a poll: "Who should lead the Avengers?"
ALL_MEMBERS_ADDED	All members are added in a chatroom	Nick Fury added all members
TOPIC_CHANGED	Chatroom topic changed	Nick Fury changed current to topic Hey
DM_REQUEST_REJECTED	Direct Messaging Request is rejected	Nick Fury and Tony Stark are connected
DM_REQUEST_ACCEPTED	Direct Messaging Request is accepted	Nick Fury rejected our request

Step 2: Pass this list in the setup() function

Next, pass the filtered state list into the LMChatCore.setup() function present in onCreate() of your Application class. This applies your preferences, ensuring unwanted state messages are hidden when the chatroom loads.

Kotlin

LMChatCore.setup(
    application = application,
    theme = lmChatTheme,
    lmChatCoreCallback = lmChatCoreCallback,
    lmChatAppearanceRequest = lmChatAppearanceRequest,
    domain = domain,
    enablePushNotifications = enablePushNotifications,
    deviceId = deviceId,
    shareLogsWithLM = shareLogsWithLM,
    excludeConversationStates = excludeConversationStates
)

Java

LMChatCore.INSTANCE.setup(
    application,
    lmChatTheme,
    lmChatCoreCallback,
    lmChatAppearanceRequest,
    domain,
    enablePushNotifications,
    deviceId,
    shareLogsWithLM,
    excludeConversationStates
);

Conclusion

By filtering state messages, you can create a cleaner and more focused chat experience. With just a few steps, you control what appears in the chatroom, ensuring users see only the most relevant updates.
