Usage

Integration

CometChatCallButtons can be used inside another widget or can be launched to a new screen by adding the following code snippet into the XML layout file.

XML

<com.cometchat.chatuikit.calls.callbutton.CometChatCallButtons
    android:id="@+id/call_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

If you're defining the CometChatCallButtons within the XML code or in your activity or fragment then you'll need to extract them and set them on the User object using the appropriate method.

Java

CometChatCallButtons cometchatCallButtons = binding.callButton; // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(getLayoutInflater());` to use views like `binding.callButton` after enabling view binding.

if (userObject != null) {
cometchatCallButtons.setUser(userObject); //Required - CometChat User object
} else if (groupObject != null) {
cometchatCallButtons.setGroup(groupObject); //Required - CometChat Group object
}

Kotlin

val cometchatCallButtons: CometChatCallButtons = binding.callButton // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(layoutInflater)` to use views like `binding.callButton` after enabling view binding.

if (userObject != null) {
    cometchatCallButtons.setUser(userObject) //Required - CometChat User object
} else if (groupObject != null) {
    cometchatCallButtons.setGroup(groupObject) //Required - CometChat Group object
}

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.

setOnVoiceCallClick

The setOnVoiceCallClick action is usually invoked when a voice call is initiated, executing predefined actions. However, by utilizing the provided code snippet, you can effortlessly tailor or override this default behavior to suit your unique requirements.

Java

cometchatCallButtons.setOnVoiceCallClick(new CometChatCallButtons.OnClick() {
    @Override
    public void onClick(User user, Group group) {
        //TODO
    }
});

Kotlin

cometchatCallButtons.setOnVoiceCallClick(CometChatCallButtons.OnClick { user, group -> 
    //TODO
})

setOnVideoCallClick

The setOnVideoCallClick action is typically triggered when a video call is initiated, executing default actions. However, with the provided code snippet, you have the flexibility to easily customize or override this default behavior according to your specific preferences or requirements.

Java

cometchatCallButtons.setOnVideoCallClick(new CometChatCallButtons.OnClick() {
    @Override
    public void onClick(User user, Group group) {
        //TODO
    }
});

Kotlin

cometchatCallButtons.setOnVideoCallClick(CometChatCallButtons.OnClick { user, group -> 
    //TODO
})

setOnError

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

Java

cometchatCallButtons.setOnError(new OnError() {
    @Override
    public void onError(CometChatException e) {
        //TODO   
    }
});

Kotlin

cometchatCallButtons.setOnError(OnError {  e ->
    //TODO
})

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 Call buttons component are as follows.

Event	Description
ccCallAccepted	Triggers when the outgoing call is accepted.
ccCallRejected	Triggers when the outgoing call is rejected.

Add CometChatCallEvents

Java

CometChatCallEvents.addListener("UNIQUE_ID", new CometChatCallEvents() {
    @Override
    public void ccCallAccepted(Call call) {
        super.ccCallAccepted(call);
    }

    @Override
    public void ccCallRejected(Call call) {
        super.ccCallRejected(call);
    }

});

Kotlin

Remove CometChatCallEvents

Java

CometChatCallEvents.removeListener("LISTENER_ID_USED_FOR_ADDING_THIS_LISTENER");

Kotlin

CometChatCallEvents.removeListener("LISTENER_ID_USED_FOR_ADDING_THIS_LISTENER")

setOutgoingCallConfiguration	Sets the configurations for outgoing call component.	.setOutgoingCallConfiguration(new OutgoingCallConfiguration)

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.

Configurations

Configurations offer the ability to customize the properties of each individual component within a Composite Component.

• Configurations expose properties that are available in its individual components.
