问题描述
我将如何去写一个Android应用程序，会上网，搜索，例如，某一个国家的首都（用户输入国的名称在搜索栏中的应用程序中），并显示应用程序中的首都名称？假设有一个网站，网上有这些信息 - 你可以去那里，键入一个国家的名称，它会给你的资本 - 这将是可能有我的应用程序搜索该网站（显然在背景中）对于信息，并将其显示在应用程序的用户？或者只是得到一个谷歌搜索的信息？在此先感谢！
How would I go about writing an Android application that will go online, search for, for example, the capital of a certain country (the user enters the name of the country in the search bar within the application), and display the name of the capital within the application? Assuming that there is a website online that has this information - you can go on there, type in the name of a country and it will give you the capital - would it be possible to have my application search that website (obviously in the background) for the information and display it to the user in the application? Or maybe just get the information with a Google search? Thanks in advance!
