java - Android Studio 中的 Stripe 集成

Question

我正在努力将 Stripe 支付网关集成到我正在开发的 Android 应用程序中。我已按照 https://stripe.com/docs/mobile/android 上列出的步骤进行操作.

当我尝试创建新卡片时出现错误。

我在我的 Activity 中运行它

saveButton.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View view) {
  Card card = new Card(
   // Get values from the form
   cardNumber.getText().toString(),
   getInteger(monthSpinner),
   getInteger(yearSpinner),
   cvc.getText().toString()
  );
 }
});

它使用 Card 模型。

卡片模型

这是我遇到的错误。

这对我来说是新的。我该怎么做才能解决这个问题？

Answer 1

由于这是 Google 搜索“如何将 Stripe 集成到 Android Studio”的热门话题，并且由于 Android Studio 删除了导入模块，这就是我解决导入的方法。

• 右键单击项目并选择 > 新建 > 模块
• 在您的目录中，将 Stripe > Stripe 文件夹下的内容复制到模块文件夹(您应该会看到一个新创建的文件夹。删除这个新文件夹的内容并粘贴 Stripe > Stripe 的内容)
• 返回 Android Studio 导航到 src 下的 build.gradle，在 dependencies 下添加 compile project(":stripe")。
• 刷新你的gradle。

编辑 1自发布此答案以来，发生了一些变化。如果您希望将 strip 添加到您的项目中，请通过 Maven 进行。只需将此行添加到您应用的 build.gradle 中的依赖项部分:

compile 'com.stripe:stripe-android:2.0.2'

EDIT 2 现在是实现而不是编译。

implementation 'com.stripe:stripe-android:6.1.2'
