BuyWithGooglePay

• Add BuyWithGooglePay to your xml layout.

        <com.certified.google_pay.BuyWithGooglePay
            android:id="@+id/btn_google_pay"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginStart="16dp"
            android:layout_marginEnd="16dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

• Align the button properly to suit your needs

Initialize the indicator

      var buyWithGoogleButton: BuyWithGooglePay = findViewById(R.id.btn_google_pay)
      // ViewBinding
      var buyWithGoogleButton = binding.btnGooglePay

Call the initialize() method

      /*
        * This step is required
        * Pass the current to the initialize method
        * You'll need to override onActivityResult too
      /*

      buyWithGoogleButton.initialize(requireActivity())

Set the price and shipping cost

     buyWithGoogleButton.setPrice(200)
     buyWithGoogleButton.setShippingCost(50)
     // OR
     buyWithGoogleButton.price = 200
     buyWithGoogleButton.shippingCost = 50

Set the indicator text color

      buyWithGoogleButton.setTextColor(ResourcesCompat.getColorStateList(resources, R.color.white, null)!!)

Set the text typeface

       buyWithGoogleButton.setTypeface(R.font.space_grotesk_regular)

Override the onActivityResult

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            // Value passed in AutoResolveHelper
            GOOGLE_PAY_REQUEST_CODE -> {
                when (resultCode) {
                    RESULT_OK ->
                        data?.let { intent ->
                            PaymentData.getFromIntent(intent)?.let(::handlePaymentSuccess)
                        }

                    RESULT_CANCELED -> {
                        // The user cancelled the payment attempt
                    }

                    AutoResolveHelper.RESULT_ERROR -> {
                        AutoResolveHelper.getStatusFromIntent(data)?.let {
                            handleError(it.statusCode)
                        }
                    }
                }
            }
        }
    }

Add methods to handle payment success and error

   indicator.stopAnimation()
   
   // Always stop the animation in onPause()
   fun handlePaymentSuccess(paymentData: PaymentData) {
       //....perform an action
   }

   fun handleError(statusCode: Int) {
        //...perform an action e.g
        Log.w("loadPaymentData failed", "Error code: $statusCode")
    }
