Question

我正在尝试使用PayPal付款方式来完成我的应用程序，将其用作大学的项目，我无法找到解决方案，我很困惑。我添加到build.gradle

//Paypal
implementation 'com.paypal.sdk:paypal-android-sdk:2.15.3'

我的请求代码：

package com.example.onix.AndroEat.Model;

    public Request() {
    }

    public Request(String phone, String name, String address, String total, String status, String comment, String paymentState, List<Order> foods) {
        this.phone = phone;
        this.name = name;
        this.address = address;

    }

    public String getTotal() {
        return total;
    }

    public void setTotal(String total) {
        this.total = total;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getComment() {
        return comment;
    }

    public void setComment(String comment) {
        this.comment = comment;
    }

    public String getPaymentState() {
        return paymentState;
    }

    public void setPaymentState(String paymentState) {
        this.paymentState = paymentState;
    }

    public List<Order> getFoods() {
        return foods;
    }

    public void setFoods(List<Order> foods) {
        this.foods = foods;
    }
}

我还有一个java类名称＆＃39; Config1里面是public static final String PAYPAL_CLIENT_ID =，如果从Sandbox在paypal上添加app，我会得到它。

Answer 1

将您的ABCGHI字符串值解析为int并将其传递到formatAmount，在下面的代码中：

BigDecimal

Answer 2

将区域设置“country”从“UK”更改为“GB”并正常工作。谢谢大家的帮助
