## Usage

### Integration

`CometChatAddMembers`, as a Composite Component, offers flexible integration options, allowing it to be launched directly via button clicks or any user-triggered action. Additionally, it seamlessly integrates into tab view controllers. With add members, users gain access to a wide range of parameters and methods for effortless customization of its user interface.

The following code snippet exemplifies how you can seamlessly integrate the GroupMembers component into your application.

<Tabs>
  <Tab title="XML">
    ```xml theme={null}
    <com.cometchat.chatuikit.addmembers.CometChatAddMembers
        android:id="@+id/add_members"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    ```
  </Tab>
</Tabs>

If you're defining the Group members within the XML code, you'll need to extract them and set them on the Group object using the appropriate method.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    CometChatAddMembers cometchatAddMembers = binding.groupMember;

    Group group = new Group();
    group.setGuid("GROUP_ID");
    group.setName("GROUP_NAME");

    cometchatAddMembers.setGroup(group);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    val cometchatAddMembers: CometChatAddMembers = binding.groupMember

    val group: Group = Group()
    group.setGuid("GROUP_ID")
    group.setName("GROUP_NAME")

    cometchatAddMembers.setGroup(group)
    ```
  </Tab>
</Tabs>

        }

    });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    cometchatAddMembers.setItemClickListener(object : OnItemClickListener<User>() {
        override fun OnItemClick(user: User, i: Int) {

        }
    })
    ```
  </Tab>
</Tabs>

***

##### 2. OnSelection

The `OnSelection` event is triggered upon the completion of a selection in `SelectionMode`. It does not have a default behavior. However, you can override its behavior using the following code snippet.

    cometchatAddMembers.setSelectionMode(UIKitConstants.SelectionMode.MULTIPLE);
    cometchatAddMembers.setOnSelection(new CometChatUsers.OnSelection() {
        @Override
        public void onSelection(List<User> list) {
            // Handle selected members here
        }
    });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin YourActivity.kt theme={null}
    cometchatAddMembers.setSelectionMode(UIKitConstants.SelectionMode.MULTIPLE)
    cometchatAddMembers.setOnSelection { list ->
        // Handle selected members here
    }
    ```
  </Tab>
</Tabs>

        @Override
        public void onError(Context context, CometChatException e) {

        }

    });
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    cometchatAddMembers.setOnError(OnError { context, e ->

    })
    ```
  </Tab>

### 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 own views, layouts, and UI elements and then incorporate those into the component.

The `Add Members` component does not provide additional functionalities beyond this level of customization.

#### SetListItemView

With this function, you can assign a custom ListItem to the Conversations Component.

You can indeed create a custom layout file named `item_list.xml` for more complex or unique list items.

Once this layout file is made, you would inflate it inside the `createView()` method of the `UsersViewHolderListener`. The inflation process prepares the layout for use in your application:

Following this, you would use the `bindView()` method to initialize and assign values to your individual views. This could include setting text on TextViews, images on ImageViews, and so on based on the properties of the Group object:

#### SetMenu

You can set the Custom Menu view to add more options to the Groups component.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    cometchatAddMembers.setMenu(View v);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    cometchatAddMembers.setMenu(v)
    ```
  </Tab>
</Tabs>

**Example**

<Frame>
  <img src="https://mintcdn.com/cometchat-22654f5b/bUk-WwSNpBXF92Yc/images/db44a33c-add_group_members_set_menu_cometchat_screens-ad55f8c59f944d27ffad1ba7c240c903.png?fit=max&auto=format&n=bUk-WwSNpBXF92Yc&q=85&s=b241cd23eb898d5514a7451ec362bff3" width="4498" height="3120" data-path="images/db44a33c-add_group_members_set_menu_cometchat_screens-ad55f8c59f944d27ffad1ba7c240c903.png" />
</Frame>

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

```xml view_menu.xml theme={null}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    tools:context=".MainActivity">

    <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}
    View view = getLayoutInflater().inflate(R.layout.view_menu, null);
    ImageView imgRefresh = view.findViewById(R.id.img_refresh);
    imgRefresh.setOnClickListener(v -> {
        Toast.makeText(requireContext(), "Clicked on Refresh", Toast.LENGTH_SHORT).show();
    });
    cometchatAddMembers.setMenu(view);
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin YourActivity.kt theme={null}
    val view: View = layoutInflater.inflate(R.layout.view_menu, null)
    val imgRefresh = view.findViewById<ImageView>(R.id.img_refresh)
    imgRefresh.setOnClickListener { v: View? ->
        Toast.makeText(requireContext(), "Clicked on Refresh", Toast.LENGTH_SHORT).show()
    }
    cometchatAddMembers.setMenu(view)
    ```
  </Tab>
</Tabs>

#### SetLoadingStateView

You can set a custom loader view using `setLoadingStateView` to match the loading view of your app.

<Tabs>
  <Tab title="Java">
    ```java theme={null}
    cometchatAddMembers.setLoadingStateView();
    ```
  </Tab>

  <Tab title="Kotlin">
    ```kotlin theme={null}
    cometchatAddMembers.setLoadingStateView()
    ```
  </Tab>
</Tabs>

</Frame>

We have added a `ContentLoadingProgressBar` to `loading_view_layout.xml`. You can choose any view you prefer. This view should be inflated and passed to the `setLoadingStateView()` method.

```xml loading_view_layout.xml theme={null}
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

    android:layout_gravity="center_vertical">

    <androidx.core.widget.ContentLoadingProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

</FrameLayout>
```

<Tabs>
  <Tab title="Java">
    ```java YourActivity.java theme={null}
    cometchatAddMembers.setLoadingStateView(R.layout.loading_view_layout);
