Users - CometChat Docs

Overview

The Users is a Component, showcasing an accessible list of all available users. It provides an integral search functionality, allowing you to locate any specific user swiftly and easily. For each user listed, the widget displays the user’s name by default, in conjunction with their avatar when available. Furthermore, it includes a status indicator, visually informing you whether a user is currently online or offline.

The Users component is composed of the following BaseComponents:

Components	Description
ListBase	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 Users component into your layout.xml file.

<com.cometchat.chatuikit.users.CometChatUsers
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/users"
        />

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 Menubar while in selection mode. This returns a list of all the users 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.

Java
Kotlin

cometChatUsers.setOnSelection(userList -> {
    // your custom action
});

2. ItemClickListener

The OnItemClickListener event is activated when you click on the UserList 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.

Java
Kotlin

users.setItemClickListener(new OnItemClickListener<User>() {
    @Override
    public void OnItemClick(User user, int position) {
        // your custom action
    }
});

3. BackPressListener

The OnBackPressListener function is built to respond when you tap the back button in the Toolbar of the activity. By default, this action has a predefined behavior: it simply closes the current activity. However, the flexibility of CometChat UI Kit allows you to override this standard behavior according to your application’s specific requirements. You can define a custom action that will be performed instead when the back button is pressed.

Java
Kotlin

users.addOnBackPressListener(() -> {
    // your custom action
});

4. onError

This action doesn’t change the behavior of the component but rather listens for any errors that occur in the User component.

Java
Kotlin

users.setOnError(new OnError() {
    @Override
    public void onError(Context context, CometChatException e) {
        //Your Exception Handling code.
    }
});

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. UserRequestBuilder

The UserRequestBuilder enables you to filter and customize the user list based on available parameters in UserRequestBuilder. This feature allows you to create more specific and targeted queries when fetching users. The following are the parameters available in UserRequestBuilder

Methods	Type	Description
setLimit	int	sets the number users that can be fetched in a single request, suitable for pagination
setSearchKeyword	String	used for fetching users matching the passed string
hideBlockedUsers	bool	used for fetching all those users who are not blocked by the logged in user
friendsOnly	bool	used for fetching only those users in which logged in user is a member
setRoles	List<String>	used for fetching users containing the passed tags
setTags	List<String>	used for fetching users containing the passed tags
withTags	bool	used for fetching users containing tags
setUserStatus	String	used for fetching users by their status online or offline
setUIDs	List<String>	used for fetching users containing the passed users

Example In the example below, we are applying a filter to the UserList based on Friends.

Java
Kotlin

UsersRequest.UsersRequestBuilder builder=new UsersRequest.UsersRequestBuilder()
                .friendsOnly(false)
                        .setLimit(10);
cometChatUsers.setUsersRequestBuilder(builder);

2. SearchRequestBuilder

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

Java
Kotlin

UsersRequest.UsersRequestBuilder builder = new UsersRequest.UsersRequestBuilder()
        .setSearchKeyword("**");
users.setSearchRequestBuilder(builder);

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 Users you have to add corresponding listeners by using CometChatUserEvents

Events	Description
ccUserBlocked	This will get triggered when the logged in user blocks another user
ccUserUnblocked	This will get triggered when the logged in user unblocks another user

Java
Kotlin

CometChatUserEvents.addUserListener("LISTENER_TAG", new CometChatUserEvents() {
            @Override
            public void ccUserBlocked(User user) {
                super.ccUserBlocked(user);
            }

            @Override
            public void ccUserUnblocked(User user) {
                super.ccUserUnblocked(user);
            }
        });

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.

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. Users Style

You can set the UsersStyle to the Users Component to customize the styling.

Java
Kotlin

UsersStyle usersStyle = new UsersStyle();
usersStyle.setBackground(Color.BLACK);

Advanced

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.

SetListItemView

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

Java
Kotlin

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

    @Override
    public void bindView(Context context, View view, User user, RecyclerView.ViewHolder viewHolder, List<User> list, int i) {
    }
});

Example

You can indeed create a custom layout file named item_conversation_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 UsersViewHolderListener. 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 User object:

YourActivity.java

users.setListItemView(new UsersViewHolderListener() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        View view = getLayoutInflater().inflate(R.layout.item_converation_list, null);
        return view;
    }
    @Override
    public void bindView(Context context, View view, User user, RecyclerView.ViewHolder viewHolder, List<User> list, int i) {
        CometChatAvatar avatarView = view.findViewById(R.id.item_avatar);
        avatarView.setRadius(100);
        TextView nameView = view.findViewById(R.id.txt_item_name);
        nameView.setText(user.getName());
        avatarView.setImage(user.getAvatar(),user.getName());
    }
});

SetSubTitleView

You can customize the subtitle view for each conversation item to meet your requirements

Java
Kotlin

users.setSubTitleView(new UsersViewHolderListener() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        return null;
    }
    @Override
    public void bindView(Context context, View view, User user, RecyclerView.ViewHolder viewHolder, List<User> list, int i) {
    }
});

Example

You can indeed create a custom layout file named subtitle_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 UsersViewHolderListener. 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 User object:

subtitle_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:text="Subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <ImageView

        android:layout_margin="2dp"
        android:layout_toRightOf="@+id/img_audio_call"
        />

    </RelativeLayout>

Java
Kotlin

users.setSubTitleView(new UsersViewHolderListener() {
    @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, User user, RecyclerView.ViewHolder viewHolder, List<User> 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(user.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();
        });
    }
});

SetTailView

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

Java
Kotlin

users.setTailView(new UsersViewHolderListener() {
    @Override
    public View createView(Context context, CometChatListItem cometChatListItem) {
        return null;
    }
    @Override
    public void bindView(Context context, View view, User user, RecyclerView.ViewHolder viewHolder, List<User> list, int i) {
    }
});

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 UsersViewHolderListener. 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 User 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:text="Subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <ImageView
        android:id="@+id/img_conversation"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

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

        android:layout_margin="2dp"
        android:layout_toRightOf="@+id/img_audio_call"
        />

    </RelativeLayout>

Java
Kotlin

users.setTailView(new UsersViewHolderListener() {
    @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, User user, RecyclerView.ViewHolder viewHolder, List<User> 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(user.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();
        });
    }
});

SetMenu

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

Java
Kotlin

users.setMenu(View 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

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

SetLoadingStateView

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

Java
Kotlin

users.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
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="?android:attr/progressBarStyleLarge"
        android:layout_gravity="center_horizontal"
        />
</FrameLayout>

Java
Kotlin

YourActivity.java

users.setLoadingStateView(R.layout.loading_view_layout);

SetEmptyStateView

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

Java
Kotlin

users.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"
    android:layout_height="match_parent"
    android:layout_gravity="center_vertical"
    >

    <TextView
        android:id="@+id/txt_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No Friends available"

SetErrorStateView

You can set a custom ErrorStateView using setErrorStateView to match the error view of your app.

Java
Kotlin

users.setErrorStateView();

Example

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

error_state_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">

    <ImageView
        android:id="@+id/img_error"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="@drawable/ic_error"
        android:layout_centerInParent="true"
        />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Something Went Wrong"
        android:textSize="30sp"
        android:layout_below="@+id/img_error"
