# Theming

The appearance of the Chat SDK can easily be customized:

1. Use a custom theme
2. Change the color scheme
3. Change the icons
4. Customize activities and fragments

### Use a custom theme

Add a theme to your app:

In the `AndroidManifest.xml`

```
<application
    android:theme="@style/YouTheme"
```

To force the Chat SDK to use your app's theme you first need to make sure your theme inherits from the Chat SDK theme:

```
<style name="YourTheme" parent="ChatSDKTheme">
```

Then:

```
UIModule.config().overrideTheme();
```

Alternatively, if you want to add a separate theme to the Chat SDK, use the following:

```
UIModule.config().setTheme(R.style.CustomChatSDKTheme);
```

Make sure this theme also uses `ChatSDKTheme` as it's parent.

### Change the color scheme

Chat SDK comes with a number of attributes that you can override to customize the color scheme:

In your theme add:

```
<resources>
    <style name="CustomChatSDKTheme" parent="ChatSDKTheme">
        <item name="colorPrimary">#FF0000</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        <item name="colorAccent">@color/accent</item>
        <item name="colorControlNormal">@color/text_primary</item>
        // Other custom attributes
    </style>
</resources>
```

* [ChatView](https://github.com/stfalcon-studio/ChatKit/blob/master/docs/COMPONENT_MESSAGES_LIST.md#styling-via-attributes)
* [MessageInput](https://github.com/stfalcon-studio/ChatKit/blob/master/docs/COMPONENT_MESSAGE_INPUT.MD)
