Customize the Frames Android SDK

Last updated: August 20, 2025

Note

Frames will be deprecated on June 30, 2026. Upgrade to Flow for mobile, our pre-built, customizable payment user interface. Flow provides a more flexible, scalable, and feature-rich integration, as well as access to additional payment methods.

When a customer initiates a payment with the Frames Android SDK, their payment information is collected via three customizable forms:

Payment Form: prompts users for their payment card details
Billing Form: prompts users for their billing information
Country Picker: prompts the user to select a country

The styling of these forms can be customized through the use of the PaymentDetailsStyle, BillingAddressDetailsStyle and CountryPickerStyle objects, which are wrapped in the PaymentFormStyle wrapper.


1public data class PaymentFormStyle(
2    public var paymentDetailsStyle: PaymentDetailsStyle = PaymentDetailsStyle(),
3    public var billingFormStyle: BillingFormStyle = BillingFormStyle()
4)
5
6public data class BillingFormStyle(
7    public var billingAddressDetailsStyle: BillingAddressDetailsStyle = BillingAddressDetailsStyle(),
8    public var countryPickerStyle: CountryPickerStyle = DefaultCountryPickerStyle.light()
9)

You can choose between three different styling options for customization, depending on how much control you need over the forms' UI design. In order of increasing complexity these are:

The default integration is the quickest way to display the forms required to collect payment information, with no additional customization required.

Localization support for the following languages is built into the default integration:

Arabic
Dutch
English
French
German
Italian
Romanian
Spanish

You can also add your own localized strings to add support for additional languages.

For basic customization, the PaymentDetailsStyle, BillingFormStyle, BillingAddressDetailsStyle and CountryPickerStyle objects expose properties that allow you to change the text and colors displayed on the forms.


1// Create a default style
2val paymentFormStyle = PaymentFormStyle()
3
4// Create a custom input component style
5val customInputComponentStyle = DefaultLightStyle.inputComponentStyle(
6    titleTextId = R.string.custom_card_number_title,
7    withLeadingIcon = true,
8    margin = Margin(bottom = 16)
9)
10
11// Modify payment form style with custom input component style
12paymentFormStyle.paymentDetailsStyle.cardNumberStyle.inputStyle = customInputComponentStyle
13
14// Hide flag images for country picker
15paymentFormStyle.billingFormStyle.countryPickerStyle.withFlag = false

If you want to customize your forms beyond what is supported by the default integration, you can apply a theme using the Theme object.

When instantiating a new Theme object, you must supply the following fields at a minimum:

accentColor
textColor
errorColor
backgroundColor
fieldBackgroundColor
enabledButtonColor
disabledButtonColor

You can then optionally provide additional values to customize other elements including button styling, custom placeholder and error text, and field input controls.

Dynamic font sizing based on the user's device is built into the Theme object.


1// Create a color object with generic colors which will be used on all screens
2private val paymentFormThemeColors = PaymentFormThemeColors(
3    accentColor = 0XFF00CC2D,
4    textColor = 0XFFB1B1B1,
5    errorColor = 0XFFFF0000,
6    backgroundColor = 0xFF17201E,
7    fieldBackgroundColor = 0XFF24302D,
8    enabledButtonColor = 0xFFFFFFFF,
9    disabledButtonColor = 0XFF003300
10)

12// Customize card number component
13private val cardNumber = PaymentFormComponentBuilder()
14    .setPaymentFormField(PaymentFormComponentField.CardNumber)
15    .setTitleTextId(R.string.cko_card_number_title)
16    .setSubTitleText("Card number is required")
17    .build()
18
19// Customize address line 1 component
20private val addressLineOne = PaymentFormComponentBuilder()
21    .setPaymentFormField(PaymentFormComponentField.AddressLineOne)
22    .setTitleTextId(R.string.cko_billing_form_input_field_address_line_one)

51        paymentFormThemeColors = paymentFormThemeColors,
52        /
53         * option 1: Use combination of default and custom components
54         */
55        paymentFormComponents = DefaultPaymentFormTheme.providePaymentFormComponents
56            cardNumber = cardNumber,
57            addressLineOne = addressLineOne,
58            addressLineTwo = addressLineTwo,
59            addBillingSummaryButton = addBillingSummaryButton,
60            editBillingSummaryButton = editBillingSummaryButton
61        ),
62        /
63         * option 2: Use default components
64         * paymentFormComponents = DefaultPaymentFormTheme.provideComponents()
65         */
66        paymentFormShape = PaymentFormShape(
67            inputFieldShape = Shape.RoundCorner,
68            addressSummaryShape = Shape.Rectangle, buttonShape = Shape.Circle
69        ),
70        paymentFormCornerRadius = PaymentFormCornerRadius(
71            inputFieldCornerRadius = CornerRadius(INPUT_FIELD_CORNER_RADIUS),
72            addressSummaryCornerRadius = CornerRadius(INPUT_FIELD_CORNER_RADIUS)
73        )
74    )
75}

For complete control over how the various UI elements on your forms look, you can use the fully custom solution.

You can use the following objects and properties to edit each individual UI component displayed across the forms:
