Stripe and dark mode

[sebj54]

Hi there!

I've been using this plugin for a while and I've noticed that fields are shown black on black with dark mode. Here are some screenshots:

Do you know how I can change that color? Maybe with a hidden API?

It seems that Stripe does not provide a way to tweak colors with their Android SDK…

Maybe this has been fixed with Stripe SDK v16.4.0 (you are using 16.1.1).

As I don't know how to update an Android dependency, feel free to make me test anything ;)

Thanks for your help!

Hi @triniwiz, just to let you know: I found a solution to change style of the Stripe inputs.

Here is the complete solution:

Add a layout for the CardMultilineWidget:

app/App_Resources/Android/src/main/res/layout/card_multiline_widget.xml

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.stripe.android.view.CardNumberTextInputLayout
        android:id="@+id/tl_card_number"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/acc_label_card_number"
        android:layout_marginTop="@dimen/stripe_add_card_element_vertical_margin"
        style="@style/MyApp.Stripe.CardMultilineWidget.TextInputLayout"
        app:hintTextAppearance="@style/MyApp.Stripe.CardMultilineWidget.TextInputLayoutAppearance"
        android:textColorHint="@color/stripe_hint_color">

        <com.stripe.android.view.CardNumberEditText
            android:id="@+id/et_card_number"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:drawablePadding="@dimen/stripe_card_icon_multiline_padding"
            android:imeOptions="actionNext"
            android:nextFocusDown="@+id/et_expiry"
            android:nextFocusForward="@+id/et_expiry"
            style="@style/MyApp.Stripe.CardMultilineWidget.TextInput" />

    </com.stripe.android.view.CardNumberTextInputLayout>

    <LinearLayout
        android:id="@+id/second_row_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:gravity="bottom"
        android:orientation="horizontal">

            android:layout_weight="1"
            android:hint="@string/acc_label_expiry_date"
            style="@style/MyApp.Stripe.CardMultilineWidget.TextInputLayout"
            app:hintTextAppearance="@style/MyApp.Stripe.CardMultilineWidget.TextInputLayoutAppearance"
            android:textColorHint="@color/stripe_hint_color">

            <com.stripe.android.view.ExpiryDateEditText

            app:hintTextAppearance="@style/MyApp.Stripe.CardMultilineWidget.TextInputLayoutAppearance"
            android:textColorHint="@color/stripe_hint_color">

        </com.google.android.material.textfield.TextInputLayout>
    </LinearLayout>
</merge>

Add the desired styles at the end of the existing styles.xml file:

app/App_Resources/Android/src/main/res/values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- your existing styles -->

    <style name="NativeScriptToolbarStyle" parent="NativeScriptToolbarStyleBase">
    </style>

    <style name="MyApp.Stripe.CardMultilineWidget.TextInputLayout" parent="Stripe.CardMultilineWidget.TextInputLayout">
    </style>

    <style name="MyApp.Stripe.CardMultilineWidget.TextInputLayoutAppearance" parent="TextAppearance.AppCompat">
        <item name="android:textColor">@color/ns_accent</item> <!-- label focused -->
    </style>

    <style name="MyApp.Stripe.CardMultilineWidget.TextInput" parent="StripeDefaultTheme">
        <item name="android:textColor">@color/stripe_input_color</item> <!-- text color (value) -->
        <item name="android:textColorHint">@color/stripe_hint_color</item> <!-- hint text color -->
        <item name="backgroundTint">@color/stripe_hint_color</item> <!-- border bottom -->
        <item name="android:textSize">18sp</item>
    </style>
</resources>

Add the required dimensions:

app/App_Resources/Android/src/main/res/values/dimens.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="stripe_add_card_element_vertical_margin">12dp</dimen>
    <dimen name="stripe_add_card_expiry_middle_margin">8dp</dimen>
    <dimen name="stripe_card_icon_multiline_padding">8dp</dimen>
    <dimen name="stripe_cmw_edit_text_minheight">48dp</dimen>
</resources>

Add the desired colors

app/App_Resources/Android/src/main/res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- your existing colors -->

    <color name="stripe_input_color">#01103b</color>
    <color name="stripe_hint_color">#7d869d</color>
</resources>

Add dark mode colors if you want

app/App_Resources/Android/src/main/res/values-night/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="stripe_input_color">#ffffff</color>
    <color name="stripe_hint_color">#e6e6e6</color>
</resources>
