​
Overview

The CometChatIncomingCall is a Component that serves as a visual representation when the user receives an incoming call, such as a voice call or video call, providing options to answer or decline the call.

​
Usage

​
Integration

CometChatIncomingCall 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 CometChatIncomingCall can be launched by adding the following code snippet into the XML layout file. 
<com.cometchat.chatuikit.calls.incomingcall.CometChatIncomingCall
    android:id="@+id/incoming_call"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
If you’re defining the CometChatIncomingCall 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. 
CometChatIncomingCall cometchatIncomingCall = binding.incomingCall; // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(getLayoutInflater());` to use views like `binding.incomingCall` after enabling view binding.

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

cometchatIncomingCall.setUser(user); //Required - set the user object
Activity and Fragment
You can integrate CometChatIncomingCall into your Activity and Fragment by adding the following code snippets into the respective classes.
YourActivity.java
CometChatIncomingCall cometchatIncomingCall;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    cometchatIncomingCall = new CometChatIncomingCall(this);

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

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

    setContentView(cometchatIncomingCall);
}

​
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.
setOnAcceptClick
The setOnAcceptClick action is typically triggered when the user clicks on the accept button, initiating a predefined action. However, by implementing the following code snippet, you can easily customize or override this default behavior to suit your specific requirements. 
cometchatIncomingCall.setOnAcceptClick(new OnClick() {
    @Override
    public void onClick() {
        //TODO
    }
});
setOnRejectClick
The setOnRejectClick action is typically triggered when the user clicks on the reject button, initiating a predefined action. However, by implementing the following code snippet, you can easily customize or override this default behavior to suit your specific requirements. 
cometchatIncomingCall.setOnRejectClick(new OnClick() {
    @Override
    public void onClick() {
        //TODO
    }
});
setOnError
You can customize this behavior by using the provided code snippet to override the setOnError and improve error handling. 
cometchatIncomingCall.setOnError(new OnError() {
    @Override
    public void onError(Context context, CometChatException e) {
        //TODO
    }
});

​
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. The IncomingCall component does not have any exposed filters.

​
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. The CometChatIncomingCall component does not have any exposed events.

​
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.

​
Style

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. IncomingCall Style

CometChatAvatar avatar = leadingView.findViewById(R.id.avatar);
User callUser = (User) call.getCallInitiator();
avatar.setAvatar(callUser.getName(), callUser.getAvatar());
leadingView.setLayoutParams(new LinearLayout.LayoutParams(
            Utils.convertDpToPx(requireContext(), 45),
