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. 
<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. 
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
}
