## Usage

### Integration

`CometChatCallLogParticipants` is a component that seamlessly integrates into your application. To present the participants of a call, you can instantiate the `CometChatCallLogParticipants` instance and provide the list of participants using its setter function. This allows for easy customization and efficient display of call participant details within your application's interface.

`CometChatCallLogParticipants` can be launched by adding the following code snippet to the XML layout file.

<Tabs>
  <Tab title="XML">
    ```xml theme={null}
    <com.cometchat.chatuikit.calls.callparticipants.CometChatCallLogParticipants
        android:id="@+id/call_log_participants"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    ```
  </Tab>
</Tabs>

If you're defining the `CometChatCallLogParticipants` within the XML code or in your activity or fragment then you'll need to extract them and set the Participants List using the `setParticipantList()` method.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    CometChatCallLogParticipants cometchatCallLogParticipants = binding.callLogParticipants; // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(getLayoutInflater());` to use views like `binding.callLogParticipants` after enabling view binding.

    cometchatCallLogParticipants.setParticipantList(participantsList); // Required - Get the Participants list from the CallLog object using getParticipants(), e.g., callLogObject.getParticipants()
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val cometchatCallLogParticipants: CometChatCallLogParticipants = binding.callLogParticipants // 'binding' is a view binding instance. Initialize it with `binding = YourXmlFileNameBinding.inflate(getLayoutInflater());` to use views like `binding.callLogParticipants` after enabling view binding.

    cometchatCallLogParticipants.setParticipantList(participantsList) // Required - Get the Participants list from the CallLog object using getParticipants(), e.g., callLogObject.getParticipants()
    ```
  </Tab>
</Tabs>

##### Activity and Fragment

You can integrate `CometChatCallLogParticipants` into your Activity and Fragment by adding the following code snippets into the respective classes.

<Tabs>

### Actions

[Actions](/ui-kit/android/v4/components-overview#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. SetOnItemClickListener

The `setOnItemClickListener` action is typically triggered when a participant in the call log is clicked, executing a predefined action. However, by implementing the provided code snippet, you can effortlessly customize or override this default behavior to meet your specific requirements.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    cometchatCallLogParticipants.setOnItemClickListener(new OnItemClickListener<Participant>() {
        @Override
        public void OnItemClick(Participant participant, int i) {
            //TODO
        }
    });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    cometchatCallLogParticipants.setOnItemClickListener(object :
        OnItemClickListener<Participant?>() {
        override fun OnItemClick(participant: Participant?, i: Int) {
            //TODO
        }
    })
    ```
  </Tab>
</Tabs>

***

### 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 `CometChatCallLogParticipants` component does not have any exposed filters.

  <img src="https://mintcdn.com/cometchat-22654f5b/t35Dbaum6Rkuz_d5/images/14dea811-call_participants_set_empty_state_view_cometchat_screens-76c70b3c023c86bfc78795e2ed2368bd.png?fit=max&auto=format&n=t35Dbaum6Rkuz_d5&q=85&s=a0c667a0d7fe67d62cabe1ec1e83bc07" width="4498" height="3120" data-path="images/14dea811-call_participants_set_empty_state_view_cometchat_screens-76c70b3c023c86bfc78795e2ed2368bd.png" />
</Frame>

You need to create a `empty_view_layout.xml` as a custom view file. Which we will inflate and pass to `.setEmptyStateView()`.

```xml empty_view_layout.xml theme={null}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <ImageView
        android:layout_width="70dp"
        android:layout_height="70dp"
        android:layout_above="@+id/txt_title"
        android:layout_centerHorizontal="true"
        android:src="@drawable/ic_error" />

    <TextView
        android:id="@+id/txt_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="Your message"
        android:textColor="@color/cometchat_grey"
        android:textSize="20sp"
        android:textStyle="bold" />

</LinearLayout>
```

You inflate the view and pass it to `setEmptyStateView`. You can get the child view reference and can handle click actions.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
     cometchatCallLogParticipants.setEmptyStateView(R.layout.empty_view_layout);
    ```

    android:orientation="horizontal">

    <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.

<Tabs>
  <Tab title="Java">
    ```java YourActivity.java theme={null}
