Group Members

Group Members — CometChat documentation.

Overview

CometChatGroupMembers is a versatile Component designed to showcase all users who are either added to or invited to a group, thereby enabling them to participate in group discussions, access shared content, and engage in collaborative activities. Group members have the capability to communicate in real-time through messaging, voice and video calls, and various other interactions. Additionally, they can interact with each other, share files, and join calls based on the permissions established by the group administrator or owner.

The CometChatGroupMembers component is composed of the following BaseComponents:

Components	Description
CometChatListBase	CometChatListBase serves as a container component equipped with a title (navigationBar), search functionality (search-bar), background settings, and a container for embedding a list view.
CometChatListItem	This component renders information extracted from a User object onto a tile, featuring a title, subtitle, leading view, and trailing view. experience, facilitating seamless navigation and interaction within the component.

Usage

Integration

CometChatGroupMembers, as a Composite Component, offers flexible integration options, allowing it to be launched directly via button clicks or any user-triggered action. Additionally, it seamlessly integrates into tab view controllers. With group members, users gain access to a wide range of parameters and methods for effortless customization of its user interface.

The following code snippet exemplifies how you can seamlessly integrate the GroupMembers component into your application.

XML

<com.cometchat.chatuikit.groupmembers.CometChatGroupMembers
    android:id="@+id/group_member"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

If you’re defining the Group members within the XML code, you’ll need to extract them and set them on the Group object using the appropriate method.

Java

CometChatGroupMembers cometchatGroupMembers = binding.groupMember;

Group group = new Group();
group.setGuid("GROUP_ID");
group.setName("GROUP_NAME");

cometchatGroupMembers.setGroup(group);

Kotlin

val cometchatGroupMembers: CometChatGroupMembers = binding.groupMember

val group: Group = Group()
group.setGuid("GROUP_ID")
group.setName("GROUP_NAME")

cometchatGroupMembers.setGroup(group)

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. SetOnItemClick

This method proves valuable when users seek to override onItemClick functionality within CometChatGroupMembers, empowering them with greater control and customization options.

The setItemClickListener action doesn’t have a predefined behavior. You can override this action using the following code snippet.

Java

cometchatGroupMembers.setItemClickListener(new OnItemClickListener<GroupMember>() {
    @Override
    public void OnItemClick(GroupMember groupMember, int i) {
        
    }
});

Kotlin

cometchatGroupMembers.setItemClickListener(object : OnItemClickListener<GroupMember?>() {
    override fun OnItemClick(groupMember: GroupMember?, i: Int) {
    }
})

---

2. SetOnItemLongClick

This method becomes invaluable when users seek to override long-click functionality within CometChatGroupMembers, offering them enhanced control and flexibility in their interactions.

The setOnLongClickListener action doesn’t have a predefined behavior. You can override this action using the following code snippet.

Java

cometchatGroupMembers.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View view) {
        return false;
    }
});

Kotlin

cometchatGroupMembers.setOnLongClickListener(OnLongClickListener { 
    false 
})

---

3. SetOnError

You can customize this behavior by using the provided code snippet to override the On Error and improve error handling.

Java

cometchatGroupMembers.setOnError(new OnError() {
    @Override
    public void onError(Context context, CometChatException e) {
        
    }
});

Kotlin

cometchatGroupMembers.setOnError(OnError { context, e -> 
    
})

---

4. AddOnBackPressListener

You can customize this behavior by using the provided code snippet to override the addOnBackPressListener and improve error handling.

Java

cometchatGroupMembers.addOnBackPressListener(new CometChatListBase.OnBackPress() {
    @Override
    public void onBack() {

    }

});

Kotlin

cometchatGroupMembers.addOnBackPressListener(CometChatListBase.OnBackPress {

})

---

5. OnSelection

The OnSelection event is triggered upon the completion of a selection in SelectionMode. It does not have a default behavior. However, you can override its behavior using the following code snippet.

Java

YourActivity.java

cometchatGroupMembers.setSelectionMode(UIKitConstants.SelectionMode.MULTIPLE);
cometchatGroupMembers.setOnSelection(new CometChatGroupMembers.OnSelection() {
    @Override
    public void onSelection(List<GroupMember> list) {
        // Handle selected group members here
    }
});

Kotlin

YourActivity.kt

cometchatGroupMembers.setSelectionMode(UIKitConstants.SelectionMode.MULTIPLE)
cometchatGroupMembers.setOnSelection { list ->
  // Handle selected group members here
}

---

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 Chat SDK.

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

Property	Description	Code
Limit	Sets the number of group members that can be fetched in a single request, suitable for pagination.	.setLimit(int)
Search Keyword	Used for fetching group members matching the passed string.	.setSearchKeyword(String)
Scopes	Used for fetching group members having matching scopes which may be of participant, moderator, admin, and owner.	.setScopes(List<String>)

Example

In the example below, we are applying a filter to the Group List based on limit and scope.

Java

GroupMembersRequest.GroupMembersRequestBuilder groupMembersRequestBuilder= new GroupMembersRequest.GroupMembersRequestBuilder(GUID).setLimit(limit);

cometchatGroupMembers.setGroupMembersRequestBuilder(groupMembersRequestBuilder);

Kotlin

val groupMembersRequestBuilder = GroupMembersRequestBuilder(GUID).setLimit(limit)

cometchatGroupMembers.setGroupMembersRequestBuilder(groupMembersRequestBuilder)

---

2. SearchRequestBuilder

The SearchRequestBuilder uses GroupsRequestBuilder enables you to filter and customize the search list based on available parameters in GroupsRequestBuilder.

This feature allows you to keep uniformity between the displayed Groups List and searched Group List.

Example

Java

GroupMembersRequest.GroupMembersRequestBuilder groupMembersRequestBuilder= new GroupMembersRequest.GroupMembersRequestBuilder(GUID).setLimit(LIMIT).setSearchKeyword(SEARCH_KEYWORD);

cometchatGroupMembers.setSearchRequestBuilder(groupMembersRequestBuilder);

Kotlin

val groupMembersRequestBuilder = GroupMembersRequestBuilder(GUID).setLimit(LIMIT).setSearchKeyword(SEARCH_KEYWORD)

cometchatGroupMembers.setSearchRequestBuilder(groupMembersRequestBuilder)

---

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.

Events emitted by the Join Group component is as follows.

Event	Description
ccGroupMemberBanned	Triggers when the group member banned from the group successfully
ccGroupMemberKicked	Triggers when the group member kicked from the group successfully
ccGroupMemberScopeChanged	Triggers when the group member scope is changed in the group

Java

CometChatGroupEvents.addGroupListener("LISTENER_ID", new CometChatGroupEvents() {
    @Override
    public void ccGroupMemberKicked(Action actionMessage, User kickedUser, User kickedBy, Group kickedFrom) {
        super.ccGroupMemberKicked(actionMessage, kickedUser, kickedBy, kickedFrom);
    }

    @Override
    public void ccGroupMemberBanned(Action actionMessage, User bannedUser, User bannedBy, Group bannedFrom) {
        super.ccGroupMemberBanned(actionMessage, bannedUser, bannedBy, bannedFrom);
    }

    @Override
    public void ccGroupMemberScopeChanged(Action actionMessage, User updatedUser, String scopeChangedTo, String scopeChangedFrom, Group group) {
        super.ccGroupMemberScopeChanged(actionMessage, updatedUser, scopeChangedTo, scopeChangedFrom, group);
    }

});

Kotlin

CometChatGroupEvents.addGroupListener("LISTENER_ID", object : CometChatGroupEvents() {
    override fun ccGroupMemberKicked(
        actionMessage: Action,
        kickedUser: User,
        kickedBy: User,
        kickedFrom: Group
    ) {
        super.ccGroupMemberKicked(actionMessage, kickedUser, kickedBy, kickedFrom)
    }

    override fun ccGroupMemberBanned(
        actionMessage: Action,
        bannedUser: User,
        bannedBy: User,
        bannedFrom: Group
    ) {
        super.ccGroupMemberBanned(actionMessage, bannedUser, bannedBy, bannedFrom)
    }

    override fun ccGroupMemberScopeChanged(
        actionMessage: Action,
        updatedUser: User,
        scopeChangedTo: String,
        scopeChangedFrom: String,

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your own views, layouts, and UI elements and then incorporate those into the component.

The Group Memebers component does not provide additional functionalities beyond this level of customization.

SetOptions

You can set a List of CometChatOption for a Members to add your custom actions to the Members. These options will be visible when swiping any Members item.

Java

cometchatGroupMembers.setOptions((context, groupMember, group) -> {
    // Handle banned member options here (return null for default behavior)
    return null;
});

Kotlin

cometchatGroupMembers.setOptions { context, groupMember, group ->
    // Handle banned member options here (return null for default behavior)
    return null
}

Example

Java

YourActivity.java

cometchatGroupMembers.setOptions((context, groupMember, group) -> {
    List<CometChatOption> optionList = new ArrayList<>();

    CometChatOption option = new CometChatOption();
    option.setId("option_send_photo");
    option.setIcon(R.drawable.ic_camera);
    option.setBackgroundColor(Color.CYAN);
    option.setOnClick(() -> {
        // Your Action onClick of option
    });
    optionList.add(option);

    CometChatOption option2 = new CometChatOption();
    option2.setId("option_audio_call");
    option2.setIcon(R.drawable.ic_call);

SetListItemView

With this function, you can assign a custom ListItem to the Conversations Component.

Java

cometchatGroupMembers.setListItemView(new GroupMembersViewHolderListeners() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        return null;
    }

    @Override
    public void bindView(Context context, View view, GroupMember groupMember, Group group, RecyclerView.ViewHolder viewHolder, List<GroupMember> list, int i) {

    }
});

Kotlin

cometchatGroupMembers.setListItemView(object : GroupMembersViewHolderListeners() {
    override fun createView(context: Context, cometChatListItem: CometChatListItem): View? {
        return null
    }

    override fun bindView(
        context: Context,
        view: View,
        groupMember: GroupMember,
        group: Group,
        viewHolder: RecyclerView.ViewHolder,
        list: List<GroupMember>,
        i: Int
    ) {
    }
})

Example

You can indeed create a custom layout file named item_list.xml for more complex or unique list items.

Once this layout file is made, you would inflate it inside the createView() method of the GroupsViewHolderListener. The inflation process prepares the layout for use in your application:

Following this, you would use the bindView() method to initialize and assign values to your individual views. This could include setting text on TextViews, images on ImageViews, and so on based on the properties of the Group object:

SetTailView

Used to generate a custom trailing view for the GroupList item. You can add a Tail view using the following method.

Java

cometchatGroupMembers.setTailView(new GroupMembersViewHolderListeners() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        return null;
    }

    @Override
    public void bindView(Context context, View view, GroupMember groupMember, Group group, RecyclerView.ViewHolder viewHolder, List<GroupMember> list, int i) {

    }
});

Kotlin

cometchatGroupMembers.setTailView(object : GroupMembersViewHolderListeners() {
    override fun createView(context: Context, cometChatListItem: CometChatListItem): View? {
        return null
    }

    override fun bindView(
        context: Context,
        view: View,
        groupMember: GroupMember,
        group: Group,
        viewHolder: RecyclerView.ViewHolder,
        list: List<GroupMember>,
        i: Int
    ) {

    }
})

Example

You can indeed create a custom layout file named tail_view_layout.xml for more complex or unique list items.

Once this layout file is made, you would inflate it inside the createView() method of the GroupsViewHolderListener. The inflation process prepares the layout for use in your application:

Following this, you would use the bindView() method to initialize and assign values to your individual views. This could include setting text on TextViews, images on ImageViews, and so on based on the properties of the Group object:

tail_view_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/txt_subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Subtitle" />

    <ImageView
        android:id="@+id/img_conversation"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txt_subtitle"
        android:layout_margin="2dp"
        android:src="@drawable/ic_message_grey" />

    <ImageView
        android:id="@+id/img_audio_call"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txt_subtitle"
        android:layout_margin="2dp"
        android:layout_toRightOf="@+id/img_conversation"
        android:src="@drawable/ic_call" />

    <ImageView
        android:id="@+id/img_video_call"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txt_subtitle"
        android:layout_margin="2dp"
        android:layout_toRightOf="@+id/img_audio_call"
        android:src="@drawable/ic_video" />

</RelativeLayout>

Java

YourActivity.java

cometchatGroupMembers.setTailView(new GroupMembersViewHolderListeners() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        View view = getLayoutInflater().inflate(R.layout.subtitle_layout, null);
        return view;
    }

    @Override
    public void bindView(Context context, View view, GroupMember groupMember, Group group, RecyclerView.ViewHolder viewHolder, List<GroupMember> list, int i) {
        TextView txtSubtitle = view.findViewById(R.id.txt_subtitle);
        ImageView imgConversation = view.findViewById(R.id.img_conversation);
        ImageView imgAudioCall = view.findViewById(R.id.img_audio_call);;
        ImageView imgVideCall = view.findViewById(R.id.img_video_call);;
        txtSubtitle.setText(group.getName());
        imgConversation.setOnClickListener(v -> {
            Toast.makeText(context, "Conversation Clicked", Toast.LENGTH_SHORT).show();
        });
        imgAudioCall.setOnClickListener(v -> {
            Toast.makeText(context, "Audio Call Clicked", Toast.LENGTH_SHORT).show();
        });
        imgVideCall.setOnClickListener(v -> {
            Toast.makeText(context, "Video Call Clicked", Toast.LENGTH_SHORT).show();
        });
    }
});

Kotlin

YourActivity.kt

cometchatGroupMembers.setTailView(object : GroupMembersViewHolderListeners() {
    override fun createView(context: Context, cometChatListItem: CometChatListItem): View {
        val view: View = layoutInflater.inflate(R.layout.subtitle_layout, null)
        return view
    }

    override fun bindView(
        context: Context,
        view: View,
        groupMember: GroupMember,
        group: Group,
        viewHolder: RecyclerView.ViewHolder,
        list: List<GroupMember>,
        i: Int
    ) {
        val txtSubtitle = view.findViewById<TextView>(R.id.txt_subtitle)
        val imgConversation = view.findViewById<ImageView>(R.id.img_conversation)
        val imgAudioCall = view.findViewById<ImageView>(R.id.img_audio_call)

        val imgVideCall = view.findViewById<ImageView>(R.id.img_video_call)

        txtSubtitle.text = group.name
        imgConversation.setOnClickListener { v: View? ->
            Toast.makeText(context, "Conversation Clicked", Toast.LENGTH_SHORT).show()
        }
        imgAudioCall.setOnClickListener { v: View? ->
            Toast.makeText(context, "Audio Call Clicked", Toast.LENGTH_SHORT).show()

        imgVideCall.setOnClickListener { v: View? ->
            Toast.makeText(context, "Video Call Clicked", Toast.LENGTH_SHORT).show()
        }
    }
})

SetMenu

You can set the Custom Menu view to add more options to the Groups component.

Java

cometchatGroupMembers.setMenu(View v);

Kotlin

cometchatGroupMembers.setMenu(v)

Example

You need to create a view_menu.xml as a custom view file. Which we will inflate and pass to .setMenu().

view_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    tools:context=".MainActivity">

    <ImageView
        android:id="@+id/img_refresh"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:src="@drawable/ic_refresh_black" />

</LinearLayout>

You inflate the view and pass it to setMenu. You can get the child view reference and can handle click actions.

Java

YourActivity.java

View view = getLayoutInflater().inflate(R.layout.view_menu, null);
ImageView imgRefresh = view.findViewById(R.id.img_refresh);
imgRefresh.setOnClickListener(v -> {
    Toast.makeText(requireContext(), "Clicked on Refresh", Toast.LENGTH_SHORT).show();
});
cometchatGroupMembers.setMenu(view);

Kotlin

YourActivity.kt

val view: View = layoutInflater.inflate(R.layout.view_menu, null)
val imgRefresh = view.findViewById<ImageView>(R.id.img_refresh)
imgRefresh.setOnClickListener { v: View? ->
    Toast.makeText(requireContext(), "Clicked on Refresh", Toast.LENGTH_SHORT).show()
}
cometchatGroupMembers.setMenu(view)

---

SetLoadingStateView

Java

cometchatGroupMembers.setLoadingStateView();

Kotlin

cometchatGroupMembers.setLoadingStateView()

Example

We have added a ContentLoadingProgressBar to loading_view_layout.xml. You can choose any view you prefer. This view should be inflated and passed to the setLoadingStateView() method.

loading_view_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_vertical">

    <androidx.core.widget.ContentLoadingProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

</FrameLayout>
