1. Select one from existing themes

Chat SDK depends on appcompat-v7 for providing backward compatibility, hence all the chat Themes are inherited from Theme.AppCompat.* themes. To switch the theme applied to chat SDK components, change the parent of Theme.Freshchat.SelectedTheme to one of the variants of Theme.Freshchat.* in your app's styles.xml



<style name="Theme.Freshchat.SelectedTheme" parent="@style/Theme.Freshchat.Light.DarkActionBar" />

Chat SDK ships with Theme.Freshchat.Light and Theme.Freshchat.Light.DarkActionBar


2. Create and apply a custom theme


Chat SDK's theming is built on top of Android theming system, and as such supports the standard android theming attributes for items like ActionBar background colour, ActionBar text color, status bar colour etc. Refer Android Design Guide: Android Material Theme Attributes


For example, to customize colorPrimary, include the following. 

<item name="colorPrimary">@color/my_awesome_color</item>



Following is a list of Freschat SDK specific customizations.


2.1 Text Appearance 

Chat SDK supports changing text appearance for several elements in the SDK. You can refer to the default text appearance implementation here: Default Styles

Note: *TextStyles listed are standard android view styles, typically for text views, and hence textAppearance can include any of the customizations like textColortextSize etc.

Steps to customize the Text  Appearance

Step 1:  Define custom Text Appearance as a style 

For example, MyCustomTextAppearance style is defined as 

<style name="MyCustomTextAppearance" parent="TextAppearance.AppCompat.Medium">

<item name="android:textColor">@color/textColorPrimary</item>

<item name="android:textColorHighlight">@color/textColorHighlight</item>

<item name="android:textColorHint">@color/textColorHint</item>

<item name="android:textColorLink">@color/textColorLink</item>

<item name="android:textSize">16sp</item>

<item name="android:textStyle">bold</item>



Step 2: Map the Text Appearance style to a predefined chat textAppearance custom attribute. 


For example, MyCustomTextAppearance style defined above is text appearance of the style freshchatChannelNameTextStyle 

<style name="MyCustomTheme" parent="Theme.Freshchat.Light.DarkActionBar">

<item name="freshchatChannelNameTextStyle">@style/CustomChannelNameTextStyle</item>


<style name="CustomChannelNameTextStyle" parent="Widget.Freshchat.ChannelName">

    <item name="android:textAppearance">@style/MyCustomTextAppearance</item>



Step 3: Set the custom theme for the all the chat SDK Activities. The simplest way to do it is to override and set the parent of Theme.Freshchat.SelectedTheme in your app's styles.xml / themes.xml

<style name="Theme.Freshchat.SelectedTheme" parent="MyCustomTheme" />


Alternately if you want to apply different themes for each activity , then include the activity entries in your app's AndroidManifest.xml and override the theme from there.


For example, include the custom theme as android:theme and tools:replace attribute to allow replacement of theme by manifest merger.


For a list of chat SDK Activities, refer : Chat Android SDK Manifest




        tools:replace="android:theme" />




        tools:replace="android:theme" />

2.3 Custom Font 

Chat supports custom font through Calligraphy

  1. Include Calligraphy as a dependency in your app by adding the following line to your app's build.gradle

  2. HTML

  3. dependencies {    compile 'uk.co.chrisjenx:calligraphy:2.1.0'}


  5. Add the font file(*.ttf) to the /assets folder of your app module.

  6. If you want to apply different fonts for each view,  specify the fontPath attribute as part of the Hotline textAppearance attributes described in section 2.1

    For example, 
    MyCustomTextAppearance style defined in 2.1 Step 1 will also have the fontPath attribute as part of it

  7. XML

  8. <style name="MyCustomTextAppearance" parent="TextAppearance.AppCompat.Medium">    <item name="fontPath">fonts/RobotoCondensed-Regular.ttf</item></style>

    Alternately If you want to apply a single font globally across all of chat UI, initialize and define your default font using 
    CalligraphyConfig, in your Application class in the onCreate() method.

  10. Java

  11. @Overridepublic void onCreate() {    super.onCreate();    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()        .setDefaultFontPath("fonts/Roboto-RobotoRegular.ttf")        .setFontAttrId(R.attr.fontPath)        .build());}
