Usage

​
Integration

CometChatOutgoingCall being a custom component, offers versatility in its integration. It can be seamlessly launched via button clicks or any user-triggered action, enhancing the overall user experience and facilitating smoother interactions within the application. Since CometChatOutgoingCall can be launched by adding the following code snippet into the XML layout file. 
<com.cometchat.chatuikit.calls.outgoingcall.CometChatOutgoingCall
    android:id="@+id/outgoing_call"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
If you’re defining the CometChatOutgoingCall within the XML code or in your activity or fragment then you’ll need to extract them and set the User object or Call object using the appropriate method. 
CometChatOutgoingCall cometchatOutgoingCall = binding.outgoingCall; // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(getLayoutInflater());` to use views like `binding.outgoingCall` after enabling view binding.

User user = new User();
user.setUid(""); //Required
user.setName(""); //Required
user.setAvatar(""); //Required

cometchatOutgoingCall.setUser(user); //Required - set the user object
//OR
cometchatOutgoingCall.setCall(call); //Required - set the call object
Activity and Fragment

    cometchatOutgoingCall = new CometChatOutgoingCall(this);

    User user = new User();
    user.setUid(""); //Required
    user.setName(""); //Required
    user.setAvatar(""); //Required

    cometchatOutgoingCall.setUser(user); //Required - set the user object

1. SetOnDeclineCallClick
The setOnDeclineCallClick action is typically triggered when the call is ended, carrying out default actions. However, with the following code snippet, you can effortlessly customize or override this default behavior to meet your specific needs. 
cometchatOutgoingCall.setOnDeclineCallClick(new OnClick() {
    @Override
    public void onClick() {
        //TODO
    }
