Voice Recording

Introduction

The UI Components Chat SDK provides the flexibility to customize the visual presentation of audio recording. You can personalize the way audio recording is displayed and make it more unique according to your preferences and requirements.

Enabling Audio Recording

MessageComposerView in Chat UI Components serves as the container where audio recording functionality is rendered. It provides the necessary components and elements to handle the recording process and display relevant user interface elements related to audio recording.

Using Theming

Let's display enabled audio recording button by setting streamUiMessageComposerAudioRecordingButtonVisible and streamUiMessageComposerAudioRecordingButtonEnabled to true in our MessageComposerViewTheme:

<style name="MessageComposerViewTheme" parent="StreamUi.MessageComposerView">
    <item name="streamUiMessageComposerAudioRecordingButtonVisible">true</item>
    <item name="streamUiMessageComposerAudioRecordingButtonEnabled">true</item>
</style>

This will show the microphone button in the MessageComposerView next to the send button.

If you want to show the send button only when there's text in the input, you can do that by setting streamUiMessageComposerAudioRecordingButtonPreferred to true in the MessageComposerViewTheme. This way, the send button will only be visible when there's something typed in the composer.

<style name="MessageComposerViewTheme" parent="StreamUi.MessageComposerView">
    <item name="streamUiMessageComposerAudioRecordingButtonVisible">true</item>
    <item name="streamUiMessageComposerAudioRecordingButtonEnabled">true</item>
    <item name="streamUiMessageComposerAudioRecordingButtonPreferred">true</item>
</style>

note

Only certain attributes were used here, you can find the rest in the source code here.

Next, set MessageComposerViewTheme to your Stream theme as shown below:

<style name="StreamTheme" parent="@style/StreamUiTheme">
    <item name="streamUiMessageComposerViewStyle">@style/MessageComposerViewTheme</item>
</style>

And finally, override streamUiTheme:

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="streamUiTheme">@style/StreamTheme</item>
</style>

Using XML Attributes

The same result can be achieved by using XML attributes directly on the MessageComposerView:

<io.getstream.chat.android.ui.feature.messages.composer.MessageComposerView
    android:id="@+id/messageComposerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:streamUiMessageComposerAudioRecordingButtonVisible="true"
    app:streamUiMessageComposerAudioRecordingButtonEnabled="true"
    app:streamUiMessageComposerAudioRecordingButtonPreferred="true"
    />

Using TransformStyle

The last but not least option is to use TransformStyle to enable the audio recording functionality:

Kotlin

TransformStyle.messageComposerStyleTransformer = StyleTransformer { defaultStyle ->
    defaultStyle.copy(
        audioRecordingButtonVisible = true,
        audioRecordingButtonEnabled = true,
        audioRecordingButtonPreferred = true,
    )
}

Java

TransformStyle.setMessageComposerStyleTransformer(source -> {
    // Customize the style
    return source;
});

note

Only certain attributes were used here, you can find the rest in the source code here.

UI Customization

Customize MessageComposerView

Using XML Attributes and Theming

Next step is to customize the UI of the audio feature components in MessageComposerView. You can do that by overriding the following attributes:

<style name="MessageComposerViewTheme" parent="StreamUi.MessageComposerView">
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordText">@string/stream_ui_message_composer_hold_to_record</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordTextSize">@dimen/stream_ui_text_medium</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordTextColor">@color/stream_ui_white_snow</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordTextStyle">bold</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordTextFont">@font/stream_roboto_medium</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordBackgroundDrawable">@drawable/stream_ui_message_composer_audio_record_hold_background</item>
    <item name="streamUiMessageComposerAudioRecordingHoldToRecordBackgroundDrawableTint">@null</item>
    <item name="streamUiMessageComposerAudioRecordingSlideToCancelText">@string/stream_ui_message_composer_slide_to_cancel</item>
    <item name="streamUiMessageComposerAudioRecordingSlideToCancelTextSize">@dimen/stream_ui_text_medium</item>
    <item name="streamUiMessageComposerAudioRecordingSlideToCancelTextColor">@color/stream_ui_text_color_secondary</item>
    <item name="streamUiMessageComposerAudioRecordingSlideToCancelTextStyle">normal</item>
    <item name="streamUiMessageComposerAudioRecordingSlideToCancelTextFont">@font/stream_roboto_medium</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingButtonIconDrawable">@drawable/stream_ui_ic_mic</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingButtonIconDrawableTint">@color/stream_ui_accent_blue</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingButtonBackgroundDrawable">@drawable/stream_ui_message_composer_audio_record_mic_background</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingButtonBackgroundDrawableTint">@null</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingLockIconDrawable">@drawable/stream_ui_ic_mic_lock</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingLockIconDrawableTint">@null</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingLockedIconDrawable">@drawable/stream_ui_ic_mic_locked</item>
    <item name="streamUiMessageComposerAudioRecordingFloatingLockedIconDrawableTint">@null</item>
    <item name="streamUiMessageComposerAudioRecordingButtonIconDrawable">@drawable/stream_ui_ic_mic</item>
    <item name="streamUiMessageComposerAudioRecordingButtonIconTintList">@null</item>
    <item name="streamUiMessageComposerAudioRecordingWaveformColor">@color/stream_ui_accent_blue</item>
    <item name="streamUiMessageComposerAudioRecordingButtonWidth">@dimen/stream_ui_message_composer_trailing_content_button_record_audio_width</item>
    <item name="streamUiMessageComposerAudioRecordingButtonHeight">@dimen/stream_ui_message_composer_trailing_content_button_record_audio_height</item>
    <item name="streamUiMessageComposerAudioRecordingButtonPadding">@dimen/stream_ui_message_composer_trailing_content_button_record_audio_padding</item>
</style>

Using TransformStyle

The same level of UI customization can be achieved by overriding messageComposerStyleTransformer in TransformStyle:

Kotlin

TransformStyle.messageComposerStyleTransformer = StyleTransformer { defaultStyle ->
    defaultStyle.copy(
        audioRecordingHoldToRecordText = context.getString(R.string.stream_ui_message_composer_hold_to_record),
        audioRecordingHoldToRecordTextStyle = TextStyle(
            size = context.getDimension(R.dimen.stream_ui_text_medium),
            color = context.getColorCompat(R.color.stream_ui_text_color_secondary),
        ),
        audioRecordingHoldToRecordBackgroundDrawable = context.getDrawableCompat(R.drawable.stream_ui_message_composer_audio_record_hold_background)!!,
        audioRecordingHoldToRecordBackgroundDrawableTint = null,
        audioRecordingSlideToCancelText = context.getString(R.string.stream_ui_message_composer_slide_to_cancel),
        audioRecordingSlideToCancelTextStyle = TextStyle(
            size = context.getDimension(R.dimen.stream_ui_text_medium),
            color = context.getColorCompat(R.color.stream_ui_text_color_secondary),
        ),
        audioRecordingSlideToCancelStartDrawable = context.getDrawableCompat(R.drawable.stream_ui_arrow_left)!!,
        audioRecordingSlideToCancelStartDrawableTint = null,
        audioRecordingFloatingButtonIconDrawable = context.getDrawableCompat(R.drawable.stream_ui_ic_mic)!!,
        audioRecordingFloatingButtonIconDrawableTint = null,
        audioRecordingFloatingButtonBackgroundDrawable = context.getDrawableCompat(R.drawable.stream_ui_message_composer_audio_record_mic_background)!!,
        audioRecordingFloatingButtonBackgroundDrawableTint = null,
        audioRecordingFloatingLockIconDrawable = context.getDrawableCompat(R.drawable.stream_ui_ic_mic_lock)!!,
        audioRecordingFloatingLockIconDrawableTint = null,
        audioRecordingFloatingLockedIconDrawable = context.getDrawableCompat(R.drawable.stream_ui_ic_mic_locked)!!,
        audioRecordingFloatingLockedIconDrawableTint = null,
        audioRecordingWaveformColor = context.getColorCompat(R.color.stream_ui_accent_blue),
        audioRecordingButtonIconDrawable = context.getDrawableCompat(R.drawable.stream_ui_ic_mic)!!,
        audioRecordingButtonIconTintList = null,
        audioRecordingButtonWidth = context.getDimension(R.dimen.stream_ui_message_composer_trailing_content_button_record_audio_width),
        audioRecordingButtonHeight = context.getDimension(R.dimen.stream_ui_message_composer_trailing_content_button_record_audio_height),
        audioRecordingButtonPadding = context.getDimension(R.dimen.stream_ui_message_composer_trailing_content_button_record_audio_padding),
    )
}

Java

TransformStyle.setMessageComposerStyleTransformer(source -> {
    // Customize the style
    return source;
});

Customize AudioRecordPlayerView app-wide

AudioRecordPlayerView is the UI component that displays the audio recording waveform, the audio recording duration and playback control buttons. It is used in:

• MessageComposerView to display the audio recording attachment in attachments preview section.
• MessageListItemView to display the audio recording attachment in message list.

Using XML Attributes and Theming

Let's override streamUiAudioRecordPlayerViewStyle in StreamTheme:

<style name="StreamTheme" parent="@style/StreamUiTheme">
  <item name="streamUiAudioRecordPlayerViewStyle">@style/AudioRecordPlayerViewTheme</item>
</style>

Override the desired attributes in AudioRecordPlayerViewTheme:

<style name="AudioRecordPlayerViewTheme" parent="StreamUi.AudioRecordPlayerView">
  <item name="streamUiAudioRecordPlayerHeight">@dimen/stream_ui_audio_record_player_height</item>

  <item name="streamUiAudioRecordPlayerSpeedButtonTextColor">@color/stream_ui_audio_record_player_speed_text_color</item>
  <item name="streamUiAudioRecordPlayerSpeedButtonTextStyle">normal</item>

</style>

Using TransformStyle

The same result can be achieved by overriding audioRecordPlayerViewStyle in TransformStyle:

Kotlin

TransformStyle.audioRecordPlayerViewStyle = StyleTransformer { defaultStyle ->
    defaultStyle.copy(
        backgroundDrawableTint = Color.YELLOW,
        playIconDrawableTint = Color.BLACK,
        waveBarColorPlayed = Color.BLACK,
        waveBarColorFuture = Color.LTGRAY,
        scrubberDrawableTint = Color.BLACK,
        durationTextStyle = TextStyle(
            size = context.getDimension(R.dimen.stream_ui_text_medium),
            color = Color.BLACK,
        ),
        isFileIconContainerVisible = false,
        padding = ViewPadding(
            start = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_start),
            top = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_top),
            end = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_end),
            bottom = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_bottom)
        ),
        progressBarDrawableTint = Color.RED
    )
}

Java

TransformStyle.setAudioRecordPlayerViewStyle(source -> {
    // Customize the style
    return source;
});

Customize AudioRecordPlayerView separately per component

MessageComposerView and MessageListItemView use the same AudioRecordPlayerView to display the audio recording attachment. If you want to customize the UI of AudioRecordPlayerView differently for MessageComposerView and MessageListItemView, you can do that as shown below.

Using XML Attributes and Theming

First, let's create separate styles for AudioRecordPlayerView in MessageComposerView and MessageListItemView:

<style name="AudioRecordPlayerViewThemeOwn" parent="StreamUi.AudioRecordPlayerView">
    <!-- your customizations for OWN messages in message list -->
</style>

<style name="AudioRecordPlayerViewThemeTheirs" parent="StreamUi.AudioRecordPlayerView">
    <!-- your customizations for THEIR messages in message list -->
</style>

<style name="AudioRecordPlayerViewThemePreview" parent="StreamUi.AudioRecordPlayerView">
    <!-- your customizations for attachmnet preview in message composer -->
</style>

Second, override default styles for MessageComposerView and MessageListItemView:

<style name="MessageListTheme" parent="StreamUi.MessageList">
    <item name="streamUiMessageListAudioRecordPlayerViewStyleOwn">@style/AudioRecordPlayerViewThemeOwn</item>
    <item name="streamUiMessageListAudioRecordPlayerViewStyleTheirs">@style/AudioRecordPlayerViewThemeTheirs</item>
</style>

<style name="MessageComposerViewTheme" parent="StreamUi.MessageComposerView">
<item name="streamUiMessageComposerAudioRecordingButtonVisible">true</item>
<item name="streamUiMessageComposerAudioRecordPlayerViewStyle">@style/AudioRecordPlayerViewThemePreview</item>
</style>

Finally, set modified streamUiMessageListStyle and streamUiMessageComposerViewStyle into StreamTheme:

<style name="StreamTheme" parent="@style/StreamUiTheme">
  <item name="streamUiMessageListStyle">@style/MessageListTheme</item>
  <item name="streamUiMessageComposerViewStyle">@style/MessageComposerViewTheme</item>
</style>

For MessageComposerView using TransformStyle

Kotlin

TransformStyle.messageComposerStyleTransformer = StyleTransformer { defaultStyle ->
    defaultStyle.copy(
        audioRecordPlayerViewStyle = AudioRecordPlayerViewStyle.default(context).copy(
            backgroundDrawableTint = Color.YELLOW,
            playIconDrawableTint = Color.BLACK,
            waveBarColorPlayed = Color.BLACK,
            waveBarColorFuture = Color.LTGRAY,
            scrubberDrawableTint = Color.BLACK,
            durationTextStyle = TextStyle(
                size = context.getDimension(R.dimen.stream_ui_text_medium),
                color = Color.BLACK,
            ),
            isFileIconContainerVisible = false,
            padding = ViewPadding(
                start = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_start),
                top = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_top),
                end = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_end),
                bottom = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_bottom)
            ),
            progressBarDrawableTint = Color.RED
        )
    )
}

Java

TransformStyle.setMssageComposerStyleTransformer(source -> {
    // Customize the style
    return source;
});

For MessageListItemView using TransformStyle

Kotlin

TransformStyle.messageListStyleTransformer = StyleTransformer { defaultStyle ->
    defaultStyle.copy(
        audioRecordPlayerViewStyle = defaultStyle.audioRecordPlayerViewStyle.copy(
            own = AudioRecordPlayerViewStyle.default(context).copy(
                backgroundDrawableTint = Color.YELLOW,
                playIconDrawableTint = Color.BLACK,
                waveBarColorPlayed = Color.BLACK,
                waveBarColorFuture = Color.LTGRAY,
                scrubberDrawableTint = Color.BLACK,
                durationTextStyle = TextStyle(
                    size = context.getDimension(R.dimen.stream_ui_text_medium),
                    color = Color.BLACK,
                ),
                isFileIconContainerVisible = false,
                padding = ViewPadding(
                    start = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_start),
                    top = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_top),
                    end = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_end),
                    bottom = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_bottom)
                ),
                progressBarDrawableTint = Color.RED
            ),
            theirs = AudioRecordPlayerViewStyle.default(context).copy(
                backgroundDrawableTint = Color.BLACK,
                playIconDrawableTint = Color.BLACK,
                waveBarColorPlayed = Color.WHITE,
                waveBarColorFuture = Color.GRAY,
                scrubberDrawableTint = Color.WHITE,
                durationTextStyle = TextStyle(
                    size = context.getDimension(R.dimen.stream_ui_text_medium),
                    color = Color.WHITE,
                ),
                isFileIconContainerVisible = false,
                padding = ViewPadding(
                    start = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_start),
                    top = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_top),
                    end = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_end),
                    bottom = context.getDimension(R.dimen.stream_ui_audio_record_player_padding_bottom)
                ),
                progressBarDrawableTint = Color.RED
            ),
        )
    )
}

Java

TransformStyle.setMessageListStyleTransformer(source -> {
    // Customize the style
    return source;
});
