CreditCardEntry

Introduction

This library provides an elegant form for credit card entry that can be easily added to a activity or fragment. Regex is used to validate credit card types and a Luhn check is performed on the card numbers. This form was inspired by the credit entry UI on Square.

  • Smooth interface
  • Identifies credit card type
  • Hides number for privacy
  • Supports VISA, MasterCard, Discover and AMEX

Including in your project

This project uses JitPack to build and release.

        ...

        maven { url "https://jitpack.io" }
    }

Add the project to your dependencies

    dependencies {

        compile 'com.github.dbachelder:CreditCardEntry:1.4.7'
    }

Using the library

Please see below for an example.

XML

        <com.devmarvel.creditcardentry.library.CreditCardForm
            android:id="@+id/credit_card_form"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:helper_text_color="@color/yellow_500"
            app:include_helper="false"
            app:include_zip="false"/>

  • app:text_color - change the input field's text color (Color.BLACK by default).
  • app:hint_text_color - change the input field's hint text color (Color.LTGRAY by default).
  • app:cursor_color - change the input field's cursor color (Color.BLACK by default).
  • app:default_text_colors - If true, use text colors provided by the app's theme instead of the values provided by app:text_color,app:hint_text_color, and app:cursor_color. This overrides the values for those three text colors and causes the text inputs to use the colors provided by the application's theme.
  • app:include_helper - boolean to show/hide the helper text under the widget (true by default (i.e. helper is shown))
  • app:helper_text_color - change the text color of the hints that appear below the widget by default.
  • app:include_zip - boolean to show/hide the zip code in the form (true by default (i.e. zip is shown))
  • app:include_exp - boolean to show/hide the exp in the form (true by default (i.e. exp is shown))
  • app:include_security - boolean to show/hide the security code in the form (true by default (i.e. security is shown))
  • app:card_number_hint - string to put in as a placeholder (hint) in the credit card number field
  • app:input_background - the drawable to use as a background (defaults to white square with black 1px border)

In code:

    public class MainActivity extends Activity {
  
      private LinearLayout linearLayout;
      private CreditCardForm form;
  
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
  
        setContentView(R.layout.activity_main);
     linearLayout = (LinearLayout) findViewById(R.id.layer);
  
        form = new CreditCardForm(this);
     linearLayout.addView(form);
     
     buttonAuthorize = (Button) findViewById(R.id.buttonAuthorize);
     buttonAuthorize.setOnClickListener(new OnClickListener() {
      
      @Override
      public void onClick(View arg0) {
       if(form.isCreditCardValid())
       {
        CreditCard card = form.getCreditCard();
        //Pass credit card to service
       }
       else
       {
        //Alert Credit card invalid
       }
      }
     });
    }
