Groups
Overview
The Groups is a Component, showcasing an accessible list of all available groups. It provides an integral search functionality, allowing you to locate any specific groups swiftly and easily. For each group listed, the group name is displayed by default, in conjunction with the group icon when available. Additionally, it provides a useful feature by displaying the number of members in each group as a subtitle, offering valuable context about group size and activity level.
- iOS
- Android
The Groups component is composed of the following BaseComponents:
Components | Description |
---|---|
CometChatList | a reusable container component having title, search box, customisable background and a List View |
ListItem | a component that renders data obtained from a User object on a Tile having a title, subtitle, leading and trailing view |
Usage
Integration
The following code snippet illustrates how you can directly incorporate the Groups component into your App.tsx
file.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
return <CometChatGroups />;
}
Actions
Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.
1. onSelection
The onSelection
event is activated when you select the done icon in the AppBar while in selection mode. This returns a list of all the Groups that you have selected.
This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const onSelectionHandler = (list: CometChat.Group[]) => {
//code
};
return (
<CometChatGroups
onSelection={onSelectionHandler}
selectionMode="multiple"
/>
);
}
- iOS
- Android
2. onItemPress
The onItemPress
event is activated when you press on the Group item. This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const onItemPresshandler = (user: CometChat.User) => {
//code
};
return (
<CometChatGroups selectionMode="none" onItemPress={onItemPresshandler} />
);
}
3. onItemLongPress
The onItemLongPress
event is activated when you Long Press on the Group item. This action does not come with any predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const onItemLongPresshandler = (group: CometChat.Group) => {
//code
};
return (
<CometChatGroups
selectionMode={"none"}
onItemLongPress={onItemLongPresshandler}
/>
);
}
4. onBack
The onBack
function is built to respond when you press the back button in the AppBar. The back button is only displayed when the prop showBackButton
is set to true.
By default, this action does not have a predefined behavior. However, you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const onBackHandler = () => {
//code
};
return <CometChatGroups showBackButton={true} onBack={onBackHandler} />;
}
5. onError
This action doesn't change the behavior of the component but rather listens for any errors that occur in the Groups component.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const onErrorHandler = (error: CometChat.CometChatException) => {
//code
};
return <CometChatGroups onError={onErrorHandler} />;
}
Filters
Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of ChatSDK.
1. GroupsRequestBuilder
The GroupsRequestBuilder enables you to filter and customize the group list based on available parameters in GroupsRequestBuilder. This feature allows you to create more specific and targeted queries when fetching groups. The following are the parameters available in GroupsRequestBuilder
Methods | Type | Description |
---|---|---|
setLimit | number | sets the number groups that can be fetched in a single request, suitable for pagination |
setSearchKeyword | string | used for fetching groups matching the passed string |
joinedOnly | boolean | to fetch only joined groups |
friendsOnly | boolean | used for fetching only those users in which logged in user is a member |
setTags | Array<string> | used for fetching groups containing the passed tags |
withTags | boolean | used to fetch tags data along with the list of groups |
Example
In the example below, we are applying a filter to the Group List based on only joined groups and setting the limit to ten.
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const groupsRequestBuilder = new CometChat.GroupsRequestBuilder()
.setLimit(10)
.joinedOnly(true);
return (
<CometChatGroups
selectionMode="none"
groupsRequestBuilder={groupsRequestBuilder}
/>
);
}
2. SearchRequestBuilder
The SearchRequestBuilder uses GroupsRequestBuilder enables you to filter and customize the search list based on available parameters in GroupsRequestBuilder.
Example
- App.tsx
import { CometChat } from "@cometchat/chat-sdk-react-native";
import { CometChatGroups } from "@cometchat/chat-uikit-react-native";
function App(): React.JSX.Element {
const searchRequestBuilder = new CometChat.GroupsRequestBuilder()
.setLimit(10)
.setSearchKeyword("custom-keyword");
return (
<CometChatGroups
selectionMode="none"
searchRequestBuilder={searchRequestBuilder}
/>
);
}
Events
Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.
To handle events supported by Groups you have to add corresponding listeners by using CometChatGroupEvents
.
The Groups component does not produce any events directly.
Customization
To fit your app's design requirements, you can customize the appearance of the conversation component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.
Style
Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.
1. Groups Style
You can set the GroupsStyle
to the Groups Component to customize the styling.
