Message Composer

Message Composer — CometChat documentation.

Overview

MessageComposer is a Component that enables users to write and send a variety of messages, including text, image, video, and custom messages.

Features such as Live Reaction, Attachments, and Message Editing are also supported by it.

MessageComposer is comprised of the following Base Components:

Base Components	Description
MessageInput	This provides a basic layout for the contents of this component, such as the TextField and buttons
ActionSheet	The ActionSheet component presents a list of options in either a list or grid mode, depending on the user’s preference

Usage

Integration

The following code snippet illustrates how you can directly incorporate the MessageComposer component into your layout.xml file.

<com.cometchat.chatuikit.messagecomposer.CometChatMessageComposer
                android:id="@+id/composer"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />

The MessageComposer is responsible for managing runtime permissions. To ensure the ActivityResultLauncher is properly initialized, its object should be created in the the onCreate state of an activity. To ensure that the composer is loaded within the fragment, it is important to make sure that the fragment is loaded in the onCreate state of the activity.

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.

1. OnSendButtonClick

The OnSendButtonClick event gets activated when the send message button is clicked. It has a predefined function of sending messages entered in the composer EditText. However, you can overide this action with the following code snippet.

Java

messageComposer.setOnSendButtonClick(new CometChatMessageComposer.SendButtonClick() {
    @Override
    public void onClick(Context context, BaseMessage baseMessage) {
        Toast.makeText(context, "OnSendButtonClicked ..", Toast.LENGTH_SHORT).show();
    }
});

Kotlin

messageComposer.setOnSendButtonClick(object : CometChatMessageComposer.SendButtonClick {
override fun onClick(context: Context, baseMessage: BaseMessage) {
    Toast.makeText(context, "OnSendButtonClicked ..", Toast.LENGTH_SHORT).show()
}
})

2. onError

This action doesn’t change the behavior of the component but rather listens for any errors that occur in the MessageList component.

Java

YourActivity.java

messageComposer.setOnError(new OnError() {
    @Override
    public void onError(Context context, CometChatException e) {
        //Your Exception Handling code.
    }
});

Kotlin

YourActivity.kt

messageComposer.setOnError(object : OnError {
    override fun onError(context: Context, e: CometChatException) {
        // Your Exception Handling code.
    }
})

---

Filters

MessageComposer component does not have any available 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 MessageComposer Component does not emit any events of its own.

---

Customization

To fit your app’s design requirements, you can customize the appearance of the MessageComposer 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. MessageComposer Style

To modify the styling, you can apply the MessageComposerStyle to the MessageComposer Component using the setStyle method.

Java

MessageComposerStyle messageComposerStyle = new MessageComposerStyle();
messageComposer.setStyle(messageComposerStyle);

Kotlin

val messageComposerStyle = MessageComposerStyle()
messageComposer.setStyle(messageComposerStyle)

The following properties are exposed by MessageComposerStyle:

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

---

setTextFormatters

Assigns the list of text formatters. If the provided list is not null, it sets the list. Otherwise, it assigns the default text formatters retrieved from the data source. To configure the existing Mentions look and feel check out CometChatMentionsFormatter

Example

Java

// Initialize CometChatMentionsFormatter
CometChatMentionsFormatter mentionFormatter = new CometChatMentionsFormatter(context);

// set style to customize composer mention text
mentionFormatter.setComposerMentionTextStyle(new MentionTextStyle()
            .setLoggedInUserTextStyle(Typeface.defaultFromStyle(Typeface.BOLD))
            .setTextColor(Color.parseColor("#000000")));

// This can be passed as an array of formatter in CometChatMessageComposer by using setTextFormatters method.
List<CometChatTextFormatter> textFormatters = new ArrayList<>();
textFormatters.add(mentionFormatter);
messageComposer.setTextFormatters(textFormatters);

Kotlin

// Initialize CometChatMentionsFormatter
val mentionFormatter = CometChatMentionsFormatter(context)
// set style to customize composer mention text
mentionFormatter.composerMentionTextStyle = MentionTextStyle()
.setLoggedInUserTextStyle(Typeface.defaultFromStyle(Typeface.BOLD))
.setTextColor(Color.parseColor("#000000"))

// This can be passed as an array of formatter in CometChatMessageComposer by using setTextFormatters method.
val textFormatters: MutableList<CometChatTextFormatter> = ArrayList()
textFormatters.add(mentionFormatter)
messageComposer.setTextFormatters(textFormatters)

AttachmentOptions

By using setAttachmentOptions(), you can set a list of custom MessageComposerActions for the MessageComposer Component. This will override the existing list of MessageComposerActions.

Java

messageComposer.setAttachmentOptions()

Kotlin

messageComposer.setAttachmentOptions()

Example

In this example, we are overriding the existing MessageComposerActions List with Capture Photo, Go Live & Payments actions.

Java

messageComposer.setAttachmentOptions(new Function4<Context, User, Group, HashMap<String, String>, List<CometChatMessageComposerAction>>() {
    @Override
    public List<CometChatMessageComposerAction> invoke(Context context, User user, Group group, HashMap<String, String> stringStringHashMap) {
        List<CometChatMessageComposerAction> actionList = new ArrayList<>();

        CometChatMessageComposerAction action1 =  new CometChatMessageComposerAction();
        action1.setTitle("Capture Photo");
        action1.setIcon(com.cometchat.chatuikit.R.drawable.ic_camera);
        action1.setOnClick(new OnClick() {
            @Override
            public void onClick() {
                Toast.makeText(context, "Capture Photo option Clicked !!!", Toast.LENGTH_SHORT).show();
            }
        });
        actionList.add(action1);

        CometChatMessageComposerAction action2 =  new CometChatMessageComposerAction();
        action2.setTitle("Go Live");
        action2.setIcon(R.drawable.broadcast_camera);
        action2.setOnClick(new OnClick() {
            @Override
            public void onClick() {
                Toast.makeText(context, "Live Option Clicked !!!", Toast.LENGTH_SHORT).show();
            }
        });
        actionList.add(action2);

        CometChatMessageComposerAction action3 =  new CometChatMessageComposerAction();
        action3.setTitle("Payments");
        action3.setIcon(R.drawable.ic_payment);
        action3.setOnClick(new OnClick() {
            @Override
            public void onClick() {
                Toast.makeText(context, "Payment Option Clicked !!!", Toast.LENGTH_SHORT).show();
            }
        });
        actionList.add(action3);
        return actionList;
    }
});

Kotlin

    messageComposer.setAttachmentOptions { context, user, group, stringStringHashMap ->
        val actionList = ArrayList<CometChatMessageComposerAction>()

        val action1 = CometChatMessageComposerAction()
        action1.title = "Capture Photo"
        action1.icon = com.cometchat.chatuikit.R.drawable.ic_camera
        action1.onClick = {
            Toast.makeText(context, "Capture Photo option Clicked !!!", Toast.LENGTH_SHORT).show()
        }
        actionList.add(action1)

        val action2 = CometChatMessageComposerAction()
        action2.title = "Go Live"
        action2.icon = R.drawable.broadcast_camera
        action2.onClick = {
            Toast.makeText(context, "Live Option Clicked !!!", Toast.LENGTH_SHORT).show()
        }
        actionList.add(action2)

        val action3 = CometChatMessageComposerAction()
        action3.title = "Payments"
        action3.icon = R.drawable.ic_payment
        action3.onClick = {
            Toast.makeText(context, "Payment Option Clicked !!!", Toast.LENGTH_SHORT).show()
        }
        actionList.add(action3)

        actionList
    }

AuxiliaryButtonView

You can insert a custom view into the MessageComposer component to add additional functionality using the following method.

Java

 messageComposer.setAuxiliaryButtonView()

Kotlin

 messageComposer.setAuxiliaryButtonView()

Please note that the MessageComposer Component utilizes the AuxiliaryButton to provide sticker functionality. Overriding the AuxiliaryButton will subsequently replace the sticker functionality.

Example

In this example, we’ll be adding a custom SOS button with click functionality. You’ll first need to create a layout file and then inflate it inside the .setAuxiliaryButtonView() function.

auxiliary_button_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <androidx.cardview.widget.CardView
        android:id="@+id/card_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:layout_margin="5dp"
        app:cardCornerRadius="10dp"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="SOS !"
            android:padding="2dp"
            android:paddingEnd="5dp"
            android:paddingStart="5dp"
            android:textColor="@color/white"
            android:background="@color/purple_700"
            />

    </androidx.cardview.widget.CardView>

</RelativeLayout>

Java

messageComposer.setAuxiliaryButtonView((context, user, group, stringStringHashMap) -> {

    View view = getLayoutInflater().inflate(R.layout.auxiliary_button_layout, null);
    CardView cardView = view.findViewById(R.id.card_button);
    cardView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, "Clicked on SOS", Toast.LENGTH_SHORT).show();
        }
    });
    return view;
});

Kotlin

messageComposer.setAuxiliaryButtonView { context, user, group, stringStringHashMap ->
    val view: View = LayoutInflater.from(context).inflate(R.layout.auxiliary_button_layout, null)
    val cardView: CardView = view.findViewById(R.id.card_button)
    cardView.setOnClickListener {
        Toast.makeText(context, "Clicked on SOS", Toast.LENGTH_SHORT).show()
    }
    view
}

---

SecondaryButtonView

You can add a custom view into the SecondaryButton component for additional functionality using the below method.

Java

messageComposer.setSecondaryButtonView()

Kotlin

messageComposer.setSecondaryButtonView()

Please note that the MessageComposer Component uses the SecondaryButton to open the ComposerActionsList. Overriding the SecondaryButton will replace the ComposerActionsList functionality.

Example

In this example, we’ll be adding a custom SOS button with click functionality. You’ll first need to create a layout file and then inflate it inside the .setSecondaryButtonView() function.

secondary_button_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <androidx.cardview.widget.CardView
        android:id="@+id/card_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:layout_margin="5dp"
        app:cardCornerRadius="10dp"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="SOS !"
            android:padding="2dp"
            android:paddingEnd="5dp"
            android:paddingStart="5dp"
            android:textColor="@color/white"
            android:background="@color/purple_700"
            />

    </androidx.cardview.widget.CardView>

</RelativeLayout>

Java

messageComposer.setSecondaryButtonView((context, user, group, stringStringHashMap) -> {

    View view = getLayoutInflater().inflate(R.layout.secondary_button_layout, null);
    CardView cardView = view.findViewById(R.id.card_button);
    cardView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, "Clicked on SOS", Toast.LENGTH_SHORT).show();
        }
    });
    return view;
});

Kotlin

messageComposer.setSecondaryButtonView { context, user, group, stringStringHashMap ->
    val view: View = LayoutInflater.from(context).inflate(R.layout.secondary_button_layout, null)
    val cardView: CardView = view.findViewById(R.id.card_button)
    cardView.setOnClickListener {
        Toast.makeText(context, "Clicked on SOS", Toast.LENGTH_SHORT).show()
    }
    view
}
