In your themes.xml:

  1. Create a style with the name="sqip.Theme.CardEntry" and parent="sqip.Theme.BaseCardEntry". Setting the parent attribute of this style to sqip.Theme.BaseCardEntry causes the custom CardEntry themeto inherit the default style of the In-App Payments SDK.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntry">
</style>
  1. To change the text of the save button, add an item with name="sqipSaveButtonText" and a string resource value.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntry">
  ...
  <item name="sqipSaveButtonText">@string/pay_button</item>
</style>
  1. Add the item with the name="colorAccent" and the value set to your desired accent color.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntry">
  ...
  <item name="sqipSaveButtonText">@string/pay_button</item>
  <item name="colorAccent">@color/red</item>
</style>

Step 2: Customize the save button and card info form

Change the appearance of the save button and the card information form to match the styles in the app's theme. This will entirely override the style for these elements, giving the application full control over their appearance.

  1. Add an item with the name="editTextStyle"and the value set to your desired style.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntryAppTheme"><item name="editTextStyle">@style/CustomEditText</item>
</style>

<style name="CustomEditText" parent="@style/Widget.AppCompat.EditText">
  <item name="android:textColor">@color/blue</item>
</style>
  1. Add an item with the name="buttonStyle" and the value set to your desired style.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntryAppTheme"><item name="buttonStyle">@style/CustomButton</item>
</style>

<style name="CustomButton" parent="Widget.AppCompat.Button.Colored">
  <item name="android:textAllCaps">false</item>
  <item name="android:textSize">18sp</item>
</style>

  1. Create an activity animation style with the parent="android:style/Animation.Activity". Set the desired animations for the payment form opening and closing.

<style name="CardEntryActivityAnimation" parent="android:style/Animation.Activity">
  <item name="android:activityOpenEnterAnimation">@anim/enter_from_bottom</item>
  <item name="android:activityOpenExitAnimation">@anim/stay_put</item>
  <item name="android:activityCloseEnterAnimation">@anim/stay_put</item>
  <item name="android:activityCloseExitAnimation">@anim/exit_to_bottom</item>
</style>
  1. Add an item with name="android:windowAnimationStyle". The value should be a reference to the activity animation style created in 1.

<style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntryAppTheme">
  ...
  <item name="android:windowAnimationStyle">@style/CardEntryActivityAnimation</item>
</style>
