需要如何从Android活动调用/使用Java Web服务的工作示例吗
我是android开发新手，需要连接到服务器并获取android活动的信息或值。请提供如何从android活动调用/使用java Web服务的工作示例 以下是我迄今为止所做的工作 创建了一个Android活动。 在eclipse中创建的类，用于计算给定半径的面积并返回值。 为上面的类创建了一个web服务，并使用WebService Explorer进行了测试，结果正常。Web服务使用端口11144进行请求，使用端口8080进行响应 我的问题是： 我是使用wsdl还是使用Java客户端作为存根？ 如果我需要使用存根，它是否像其他java类一样只是另一个impo需要如何从Android活动调用/使用Java Web服务的工作示例吗,android,service,android-activity,web,wsdl,Android,Service,Android Activity,Web,Wsdl,我是android开发新手，需要连接到服务器并获取android活动的信息或值。请提供如何从android活动调用/使用java Web服务的工作示例 以下是我迄今为止所做的工作 创建了一个Android活动。 在eclipse中创建的类，用于计算给定半径的面积并返回值。 为上面的类创建了一个web服务，并使用WebService Explorer进行了测试，结果正常。Web服务使用端口11144进行请求，使用端口8080进行响应 我的问题是： 我是使用wsdl还是使用Java客户端作为存根？

谢谢你的快速回复。请告诉我如何将参数传递给Java方法并返回结果。只需像postData一样调用此方法（“您的web URL”，“您想要保存在数据库中的任何数据”）；您的Web服务中有一些方法可以与服务器连接，您可以使用这些方法创建url，并将其作为参数传递给我上面提到的方法，谢谢您的快速回复。请告诉我如何将参数传递给Java方法并返回结果。只需像postData一样调用此方法（“您的web URL”，“您想要保存在数据库中的任何数据”）；您的Web服务中有一些方法可以与服务器连接，您可以使用这些方法创建url，并将其作为参数传递给我上面提到的方法
