Message Composer

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.

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" />
Warning

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.

setOnSendButtonClick​

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.

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

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

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

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

YourActivity.java
messageComposer.setOnTextChangedListener(new CometChatTextWatcher() {
            @Override
            public void onTextChanged(CharSequence charSequence, int start, int before, int count) {

            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            }

            @Override
            public void afterTextChanged(Editable editable) {

            }
        });

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.

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

Image
themes.xml

<style name="CustomMessageComposerMentionsStyle" 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>

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

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

// 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);

setAttachmentOptions​

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

cometChatMessageComposer.setAttachmentOptions()

Example

Image

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


    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);

        CometChatMessageComposerAction action3 = new CometChatMessageComposerAction();
        action3.setTitle("Custom Option 3");
        action3.setIcon(R.drawable.ic_cp_3);
        action3.setOnClick(new OnClick() {
            @Override
            public void onClick() {
                Toast.makeText(context, "Custom Option 3 !!!", Toast.LENGTH_SHORT).show();
            }
        });
        actionList.add(action3);

        CometChatMessageComposerAction action4 = new CometChatMessageComposerAction();
        action4.setTitle("Custom Option 4");
        action4.setIcon(R.drawable.ic_cp_4);
        action4.setOnClick(new OnClick() {
            @Override
            public void onClick() {
                Toast.makeText(context, "Custom Option 4 !!!", Toast.LENGTH_SHORT).show();
            }
        });
        actionList.add(action4);

    cometChatMessageComposer.setAttachmentOptions(actionList);

setAuxiliaryButtonView​

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

 cometChatMessageComposer.setAuxiliaryButtonView()

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

Example

Image

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.

ImageView imageView = new ImageView(context);
imageView.setMaxHeight(getResources().getDimensionPixelSize(com.cometchat.chatuikit.R.dimen.cometchat_24dp));
imageView.setImageResource(R.drawable.ic_location);
imageView.setOnClickListener(v -> Toast.makeText(context, "Auxiliary Button Clicked !!!", Toast.LENGTH_SHORT).show());

cometChatMessageComposer.setAuxiliaryButtonView(imageView);

setSendButtonView​

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

    cometChatMessageComposer.setSendButtonView(view);

Example

        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(YourActivity.this, "Custom Send Button Clicked !!!", Toast.LENGTH_SHORT).show();
            }
        });
        cometChatMessageComposer.setSendButtonView(imageView);

HeaderView​

You can set custom headerView to the MessageComposer component using the following method

cometChatMessageComposer.setHeaderView(view);

Example

Image

In the following example, we're going to apply a mock smart reply view to the MessageComposer Component using the .setHeaderView() method.
