You can customize the payment form UI by overriding the sqip.Theme.CardEntry theme resource. The style attributes that you can set are called out in this image:


The SDK honors customization of system style attributes and provides three custom style attributes. The following table shows the most useful style attributes:

Style attribute Styled UI element
colorPrimaryDark The color of the status bar.
colorPrimary The color of the action bar.
windowBackground The background of the payment form.
fontFamily The font family applied to all text in the payment form.
textColorHint The color of hint text of the card entry input.
colorAccent The color of the elements with input focus, the active button text, loading indicator, and text cursor.
Custom: sqipErrorColor The color of invalid text input.
Custom: sqipSaveButtonText The text of the button that the customer clicks to submit card information.
Custom: sqipActivityTitle The title of the payment form displayed in the action bar.

Step 1: Customize text colors Permalink Get a link to this section

In your themes.xml file:

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

    <style name="sqip.Theme.CardEntry" parent="sqip.Theme.BaseCardEntry">
  2. 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>
  3. Add the item with 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>

Step 2: Customize the save button and card information form Permalink Get a link to this section

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

  1. Add an item with 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 name="CustomEditText" parent="@style/Widget.AppCompat.EditText">
      <item name="android:textColor">@color/blue</item>
  2. Add an item with 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 name="CustomButton" parent="Widget.AppCompat.Button.Colored">
      <item name="android:textAllCaps">false</item>
      <item name="android:textSize">18sp</item>

Step 3: Customize the entrance and exit animations Permalink Get a link to this section

  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>
  2. Add an item with name="android:windowAnimationStyle". The value should be a reference to the activity animation style created in step 1.

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