Android Studio中的条带集成

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上列出的步骤操作.

当我尝试创建一张新卡时,我收到错误.

我在我的活动中运行这个

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()
  );
 }
});

哪个使用卡模型.

这是我得到的错误.

这对我来说是新的.我该怎么做才能解决这个问题？

Answer 1

由于这是谷歌搜索"如何将条带集成到Android Studio"的热门话题,因此Android工作室删除了导入模块,这就是我解决导入问题的方法.

• 右键单击项目,然后选择>新建>模块
• 在您的目录下条复制内容>条纹文件夹复制到文件夹模块(你应该看到一个新创建的文件夹.删除此新文件夹的内容并粘贴条纹>条纹的内容)
• 返回Android Studio导航到src下的build.gradle,在依赖项下添加编译项目(":stripe").
• 刷新你的gradle.

编辑1 自发布此答案以来,发生了一些变化.如果您希望通过Maven将条带添加到项目中.只需将此行添加到依赖项部分内的应用程序的build.gradle中:

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

编辑2它现在是实现而不是编译.

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