Transfer Ownership - CometChat Docs

Overview

CometChatTransferOwnership is a Component that allows the current owner or administrator of a group to transfer the ownership rights and administrative control of that group to another user. By transferring ownership, the original owner can designate a new user as the group owner, giving them full control and administrative privileges over the group. CometChatTransferOwnership is a Component that allows the current owner or administrator of a group to transfer the ownership rights and administrative control of that group to another user. By transferring ownership, the original owner can designate a new user as the group owner, giving them full control and administrative privileges over the group. Here are some key points regarding the transfer ownership feature in CometChat:

Administrative Control: The current owner or administrator of the group has the authority to initiate the transfer of ownership. This feature is typically available to ensure flexibility and allow smooth transitions of group ownership.
New Group Owner: During the transfer process, the current owner can select a specific user from the group members to become the new owner. This new owner will then assume the responsibilities and privileges associated with being the group owner.
Administrative Privileges: As the new owner, the designated user will gain full administrative control over the group. They will have the ability to manage group settings, add or remove members, moderate conversations, and perform other administrative actions.
Group Continuity: Transferring ownership does not disrupt the existing group or its content. The transfer ensures the continuity of the group while transferring the administrative control to a new owner.

The Transfer Ownership component is composed of the following BaseComponents:

Components	Description
CometchatGroupMembers	`CometChatGroupMembers` is an independent component designed to create a user-friendly screen for browsing and managing group members. Users can effortlessly search for specific members and transfer ownership
CometChatListItem	This component renders information extracted from a `User` object onto a tile, featuring a title, subtitle, leading view, and trailing view.

Usage

Integration

CometChatTransferOwnership, as a composed of the CometChatGroupMembers, offers flexible integration options, allowing it to be launched directly via button clicks or any user-triggered action. Additionally, it seamlessly integrates into activity and Fragment. With transfer ownership, users gain access to a wide range of parameters and methods for effortless customization of its user interface. Since CometChatTransferOwnership is a custom view, It can be launched by adding the following code snippet into the XML layout file.

<com.cometchat.chatuikit.transferownership.CometChatTransferOwnership
    android:id="@+id/transfer_ownership"
    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
Kotlin

CometChatTransferOwnership cometchatTransferOwnership = binding.groupMember;

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

cometchatTransferOwnership.setGroup(group);

val cometchatTransferOwnership: CometChatTransferOwnership = binding.groupMember

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

cometchatTransferOwnership.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 CometChatTransferOwnership, empowering them with greater control and customization options. The setOnItemClick action doesn’t have a predefined behavior. You can override this action using the following code snippet.

Java
Kotlin

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

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

2. SetOnError

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

Java
Kotlin

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

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

3. SetOnTransferOwnership

The setOnTransferOwnership action is activated when you select a group member and click on the transfer ownership submit button. you have the flexibility to override this event and tailor it to suit your needs using the following code snippet.

Java
Kotlin

cometchatTransferOwnership.setOnTransferOwnership(new CometChatTransferOwnership.OnTransferOwnership() {
    @Override
    public void onTransferOwnership(Context context, Group group, GroupMember groupMember) {
        // Handle ownership transfer here
    }
});

cometchatTransferOwnership.setOnTransferOwnership { context, group, groupMember ->
    // Handle ownership transfer here
}

4. AddOnBackPressListener

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

Java
Kotlin

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

    }

});

cometchatTransferOwnership.addOnBackPressListener(CometChatListBase.OnBackPress {

})

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. GroupMembersRequestBuilder

The GroupMembersRequestBuilder enables you to filter and customize the group members list based on available parameters in GroupMembersRequestBuilder. This feature allows you to create more specific and targeted queries when fetching groups. The following are the parameters available in GroupMembersRequestBuilder

Property	Description	Code
Limit	Sets the number of members that can be fetched in a single request, suitable for pagination	`.setLimit(Int)`
Search Keyword	Used for fetching members matching the passed string	`.setSearchKeyword(String)`
Scope	Used for fetching group members based on multiple scopes	`.setScope(List<String>)`

Example

Java
Kotlin

GroupMembersRequest.GroupMembersRequestBuilder groupMembersRequestBuilder = new GroupMembersRequest.GroupMembersRequestBuilder("GUID")
        .setLimit(1);

cometchatTransferOwnership.setGroupMembersRequestBuilder(groupMembersRequestBuilder);

val groupMembersRequestBuilder = GroupMembersRequestBuilder("GUID")
    .setLimit(1)

cometchatTransferOwnership.setGroupMembersRequestBuilder(groupMembersRequestBuilder)

2. SearchRequestBuilder

The SearchRequestBuilder uses GroupMembersRequestBuilder enables you to filter and customize the search list based on available parameters in GroupMembersRequestBuilder. This feature allows you to keep uniformity between the displayed Group Members List and searched Group Members List. Example

Java
Kotlin

GroupMembersRequest.GroupMembersRequestBuilder groupMembersRequestBuilder = new GroupMembersRequest.GroupMembersRequestBuilder("GUID")
        .setLimit(1)
        .setSearchKeyword("SEARCH_KEYWORD");

cometchatTransferOwnership.setSearchRequestBuilder(groupMembersRequestBuilder);

val groupMembersRequestBuilder = GroupMembersRequestBuilder("GUID")
    .setLimit(1)
    .setSearchKeyword("SEARCH_KEYWORD")

cometchatTransferOwnership.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
ccOwnershipChanged	Triggers when the ownership of a group member is changed successfully

Example

Java
Kotlin

CometChatGroupEvents.addGroupListener("LISTENER_ID", new CometChatGroupEvents() {
    @Override
    public void ccOwnershipChanged(Group group, GroupMember newOwner) {
        super.ccOwnershipChanged(group, newOwner);
    }
});

CometChatGroupEvents.addGroupListener("LISTENER_ID", object : CometChatGroupEvents() {
    override fun ccOwnershipChanged(group: Group, newOwner: GroupMember) {
        super.ccOwnershipChanged(group, newOwner)
    }
})

Remove the added listener

Java
Kotlin

CometChatGroupEvents.removeListener("LISTENER_ID");Q

CometChatGroupEvents.removeListener("LISTENER_ID")

Advance

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 views, layouts, and UI elements and then incorporate those into the component.

ListItemView

Utilize this property to assign a custom ListItem to the TransferOwnership Component, allowing for enhanced customization and flexibility in its rendering.

Java
Kotlin

cometchatTransferOwnership.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) {

    }
});

cometchatTransferOwnership.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 GroupMembersViewHolderListeners.. 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:

Kotlin

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

            Toast.makeText(context, "Video Call Clicked", Toast.LENGTH_SHORT).show()
        }
    }
})

SetTailView

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

Java
Kotlin

cometchatTransferOwnership.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) {

    }
});

cometchatTransferOwnership.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 GroupMembersViewHolderListeners.. 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
Kotlin

YourActivity.java

cometchatTransferOwnership.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();
        });
    }
});

YourActivity.kt

cometchatTransferOwnership.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()
        }

            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
Kotlin

cometchatTransferOwnership.setMenu(View v);

cometchatTransferOwnership.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
Kotlin

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();
});
cometchatTransferOwnership.setMenu(view);

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()
}
cometchatTransferOwnership.setMenu(view)

SetLoadingStateView

You can set a custom loader view using setLoadingStateView to match the loading view of your app.

Java
Kotlin

cometchatTransferOwnership.setLoadingStateView();

cometchatTransferOwnership.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" />

SetEmptyStateView

You can set a custom EmptyStateView using setEmptyStateView to match the empty view of your app.

Java
Kotlin

cometchatTransferOwnership.setEmptyStateView();

cometchatTransferOwnership.setEmptyStateView()

Examples We have added an error view to empty_view_layout.xml. You can choose any view you prefer. This view should be inflated and passed to the setEmptyStateView() method.

empty_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"
