Close a poll

You can close a poll by specifying the pollId in the closePoll() method.

fun closePoll(channel: GroupChannel, pollId: Long) {
    channel.closePoll(pollId) { poll, e ->
        if (e != null) {
            // Handle error.
        }

        // The poll has been successfully closed.
        // Update or check `closeAt` here to reflect the change in the UI.
    }
}

Through PollHandler, the Sendbird server always notifies whether your poll has been successfully closed.

fun interface PollHandler {
    fun onResult(poll: Poll?, e: SendbirdException?)
}

When integrating polls in your application, managing the closeAt property is crucial for a smooth user experience. Here are guidelines for handling this property effectively:

• Closed polls: When rendering a list of messages, check if the poll's closeAt time is in the past compared to the current time. If it is, display the poll using a "closed" UI state. Note that differences between device and server time might affect this comparison.

• Active channel scenario: If a user is already in a chanel and remains in a channel past the closeAt time, implement a real-time timer to check closeAt against the current time and update the UI accordingly.

• UI update on re-entry: Make sure the UI updates correctly to show the poll's closed state if closeAt has passed while the user was away in another view.

• Error handling: Prevent users from interacting with closed polls by updating the UI and handling errors appropriately if they attempt to vote after closeAt.

• Consistent logic: Apply the same real-time checks and UI updates in standalone poll views as in message lists.
