Compact Message Composer

A compact, single-line message input component with rich text formatting, attachments, mentions, and voice recording support.

Overview

CometChatCompactMessageComposer is a Component that provides a compact, single-line message input designed for chat applications. It offers a streamlined interface with optional rich text formatting capabilities, supporting bold, italic, strikethrough, code, links, lists, and blockquotes.

Features such as Rich Text Formatting, Attachments, Message Editing, Mentions, Stickers, and Voice Recording are supported.

Usage

Integration

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

<com.cometchat.chatuikit.compactmessagecomposer.CometChatCompactMessageComposer
    android:id="@+id/compact_message_composer"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

The CompactMessageComposer is responsible for managing runtime permissions. To ensure the ActivityResultLauncher is properly initialized, its object should be created in 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.

setOnSendClickListener

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

Java

compactMessageComposer.setOnSendClickListener(new CometChatCompactMessageComposer.SendButtonClickListener() {
    @Override
    public void onSendClick(Context context, BaseMessage baseMessage) {
        Toast.makeText(context, "OnSendButtonClicked ..", Toast.LENGTH_SHORT).show();
    }
});

Kotlin

compactMessageComposer.setOnSendClickListener(
    CometChatCompactMessageComposer.SendButtonClickListener { context, baseMessage ->
        Toast.makeText(context, "OnSendButtonClicked ..", Toast.LENGTH_SHORT).show()
    }
)

setOnErrorListener

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

Java

compactMessageComposer.setOnErrorListener(new CometChatCompactMessageComposer.OnErrorListener() {
    @Override
    public void onError(Exception e) {
        // Your Exception Handling code.
    }
});

Kotlin

compactMessageComposer.setOnErrorListener(
    CometChatCompactMessageComposer.OnErrorListener { e ->
        // Your Exception Handling code.
    }
)

setOnTextChangeListener

Function triggered whenever the message input’s text value changes, enabling dynamic text handling.

Java

compactMessageComposer.setOnTextChangeListener(new CometChatCompactMessageComposer.OnTextChangeListener() {
    @Override
    public void onTextChange(String text) {
        // Handle text change
    }
});

Kotlin

compactMessageComposer.setOnTextChangeListener(
    CometChatCompactMessageComposer.OnTextChangeListener { text ->
        // Handle text change
    }
)

setOnAttachmentClickListener

This action is triggered when the attachment button is clicked. You can override the default attachment sheet behavior with a custom implementation.

Java

compactMessageComposer.setOnAttachmentClickListener(new CometChatCompactMessageComposer.OnAttachmentClickListener() {
    @Override
    public void onAttachmentClick() {
        // Your custom attachment handling
    }
});

Kotlin

compactMessageComposer.setOnAttachmentClickListener(
    CometChatCompactMessageComposer.OnAttachmentClickListener {
        // Your custom attachment handling
    }
)

Filters

CompactMessageComposer 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 CompactMessageComposer Component does not emit any events of its own.

---

Customization

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

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

themes.xml

<style name="CustomCompactMessageComposerMentionsStyle" parent="CometChatMessageComposerMentionsStyle">
    <item name="cometchatMentionTextAppearance">?attr/cometchatTextAppearanceBodyRegular</item>
    <item name="cometchatMentionTextColor">#000000</item>
    <item name="cometchatMentionBackgroundColor">#000000</item>
    <item name="cometchatSelfMentionTextColor">#30A46C</item>
    <item name="cometchatSelfMentionTextAppearance">?attr/cometchatTextAppearanceBodyRegular</item>
    <item name="cometchatSelfMentionBackgroundColor">#30A46C</item>
</style>

Java

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

// set style to customize composer mention text
mentionFormatter.setMessageComposerMentionTextStyle(context, R.style.CustomCompactMessageComposerMentionsStyle);

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

Kotlin

// Initialize CometChatMentionsFormatter
val mentionFormatter = CometChatMentionsFormatter(context)
// set style to customize composer mention text
mentionFormatter.setMessageComposerMentionTextStyle(context, R.style.CustomCompactMessageComposerMentionsStyle)

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

setAttachmentOptions

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

Java

compactMessageComposer.setAttachmentOptions(actionList);

Kotlin

compactMessageComposer.setAttachmentOptions(actionList)

Example

In this example, we are overriding the existing MessageComposerActions List with custom actions.

Java

List<CometChatMessageComposerAction> actionList = new ArrayList<>();

CometChatMessageComposerAction action1 = new CometChatMessageComposerAction();
action1.setTitle("Custom Option 1");
action1.setIcon(R.drawable.ic_cp_1);
action1.setOnClick(new OnClick() {
    @Override
    public void onClick() {
        Toast.makeText(context, "Custom Option 1 !!!", Toast.LENGTH_SHORT).show();
    }
});
actionList.add(action1);

CometChatMessageComposerAction action2 = new CometChatMessageComposerAction();
action2.setTitle("Custom Option 2");
action2.setIcon(R.drawable.ic_cp_2);
action2.setOnClick(new OnClick() {
    @Override
    public void onClick() {
        Toast.makeText(context, "Custom Option 2 !!!", Toast.LENGTH_SHORT).show();
    }
});
actionList.add(action2);

compactMessageComposer.setAttachmentOptions(actionList);

Kotlin

val actionList = ArrayList<CometChatMessageComposerAction>()

val action1 = CometChatMessageComposerAction()
action1.title = "Custom Option 1"
action1.icon = R.drawable.ic_cp_1
action1.onClick = {
    Toast.makeText(context, "Custom Option 1 !!!", Toast.LENGTH_SHORT).show()
}
actionList.add(action1)

val action2 = CometChatMessageComposerAction()
action2.title = "Custom Option 2"
action2.icon = R.drawable.ic_cp_2
action2.onClick = {
    Toast.makeText(context, "Custom Option 2 !!!", Toast.LENGTH_SHORT).show()
}
actionList.add(action2)

compactMessageComposer.setAttachmentOptions(actionList)

---

setAuxiliaryButtonView

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

Java

compactMessageComposer.setAuxiliaryButtonView(view);

Kotlin

compactMessageComposer.setAuxiliaryButtonView(view)

Please note that the CompactMessageComposer 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 button with click functionality. You’ll first need to create a layout file and then inflate it inside the .setAuxiliaryButtonView() function.

Java

ImageView imageView = new ImageView(this);
imageView.setImageResource(R.drawable.save_icon);
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);

linearLayout.addView(imageView);
compactMessageComposer.setAuxiliaryButtonView(linearLayout);

Kotlin

val imageView = ImageView(this)
imageView.setImageResource(R.drawable.save_icon)
val linearLayout = LinearLayout(this)
linearLayout.orientation = LinearLayout.HORIZONTAL

linearLayout.addView(imageView)
compactMessageComposer.setAuxiliaryButtonView(linearLayout)

---

setSendButtonView

You can set a custom view in place of the already existing send button view using the following method.

Java

compactMessageComposer.setSendButtonView(view);

Kotlin

compactMessageComposer.setSendButtonView(view)

Example

drawable/custom_send_button.xml
