Customize payment buttons

Overview

For most integrations, the default PayPalButton is sufficient, because the PaymentButton utilizes material theming, which enables the buttons to adapt to match the other buttons in your app. However, if you want greater control over your buttons customization, we offer several buttons with customization options.

Payment button

The PaymentButton is the parent for all other buttons in the Native Checkout SDK for Android. The following attributes are available for use on every child button:

Attribute	Property	Description
payment_button_size	size	Adjusts the minimum height of the button. The default value is medium, but can also be set to: large or small.
payment_button_shape	shape	Overrides the shape of the button. The default shape derives from the theme of your app, but you can set it to: pill, rectangle, or rounded.

Payment button eligibility

To ensure buyers have an optimal experience, every PaymentButton adheres to strict eligibility requirements. Generally, the PayPalButton is always Eligible so it's safe to fallback for other buttons. The button offers functional and non-functional properties to observe on the status. For example:

    val paymentButton: PaymentButton //...

    // Functional
    paymentButton.onEligibilityStatusChanged = { buttonEligibilityStatus: PaymentButtonEligibilityStatus ->
        Log.i("PaymentButtonEligibility", "eligibility: $buttonEligibilityStatus")
    }

    // Non-functional
    paymentButton.paymentButtonEligibilityStatusChanged = object : PaymentButtonEligibilityStatusChanged {
        override fun onPaymentButtonEligibilityStatusChanged(paymentButtonEligibilityStatus: PaymentButtonEligibilityStatus) {
            Log.i("PaymentButtonEligibility", "$paymentButton : $paymentButtonEligibilityStatus")
        }
    }

    paymentButton.setPaymentButtonEligibilityStatusChanged(new PaymentButtonEligibilityStatusChanged() {
        @Override
        public void onPaymentButtonEligibilityStatusChanged(@NotNull PaymentButtonEligibilityStatus paymentButtonEligibilityStatus) {
            Log.i("PaymentButtonEligibility", String.format("paymentButton : %s", paymentButtonEligibilityStatus));
        }
    });

Both properties emit one value at a minimum, as the current value is emitted when either property is set. This is useful because the SDK retrieves funding eligibility requirements as soon as PayPalCheckout.setConfig is invoked. Usually, the funding eligibility retrieves by the time the PaymentButton renders. If funding eligibility isn't retrieved, the buttons are disabled and display a loading state.

You can also retrieve the current status through the eligibilityStatus property. The following are possible values:

Status	Description
Eligible	The button is visible and enabled, so buyers can interact with it.
Error	The button is disabled and the visibility is set hidden. This status only returns if there's an error retrieving the eligibility status.
Ineligible	The button is disabled and the visibility is set to hidden.
Loading	The button is visible, but disabled and displaying a loading indicator.

PayPal button

Attribute	Property	Description
paypal_color	color	Changes the background color of the button and adjusts the wordmark color to be visible. The default value is gold, but you can also set it to: black, blue, silver, or white.
paypal_label	label	Adds a label on the button itself. The default value is no label, which is set with paypal, but you can also set it to: checkout, buy_now, or pay.

Pay Later button

The PayLaterButton overrides the PayPalButton and always displays the Pay Later branding on the button as a label. You can't modify the label, but you can change the color to any color available for the PayPalButton.

PayPal Credit button

Attribute	Property	Description
paypal_credit_color	color	Changes the background color of the button and adjusts the wordmark to be visible. You can set it to dark_blue or black.
