如何获取实时汇率数据并将其应用于Android App？

Question

How to get a live exchange rate data and apply it to an Android App? Currently creating a currency exchange as my project.

Answer 1

Welcome to SO. I would say the best thing for you to do is to read up on:

• Currency rate APIs, such as Xurrency.com
• Android Development

If there's a specific problem you're running into with your project, I'm sure the folks here on SO would love to hear more details about your problem in order to help.

Best,

Answer 2

I would imagine you have to make your application connect to some kind of webservice to retrieve the exchange rate data needed.

• http://www.anddev.org/calling_a_web_service_from_android-t348.html has some indications.
• I suggest you read the book from M. Murphy ( Begginning Android ). Chap 22 says :

Android does not have built-in SOAP or XML-RPC client APIs. However, it does have the Apache HttpComponents library baked in. You can either layer a SOAP/XML-RPC layer atop this library, or use it “straight” for accessing REST-style Web services. For the purposes of this book, “RESTstyle Web services” is defined as simple HTTP requests for ordinary URLs over the full range of HTTP verbs, with formatted payloads (XML, JSON, etc.) as responses.
