要素自动添加到一个数组 [英] Automatic adding of elements to an array
问题描述
你好，我在Java的不特定的很好，所以请多多包涵。我想现在写了一个非常简单的Android应用程序，我需要一些编码帮助。
Hi I'm not particular good at Java so please bear with me. I'm trying to write a very simple android app now and I need help with some coding.
事情是，我有一个自动生成.png文件，并将它们保存到一个公共目录中数字顺序的服务器。每天发生的更新和非穷尽的。
Thing is, I have a server that automatically generates .png files and saves them to a public directory in a numerical order. The update occurs daily and is non-exhaustive.
反正我在其中可分配动态值，以我的应用程序内的阵列？
Is there anyway in which I can assign the dynamic values to an array within my app?
private String[] myRemoteImages = {
"http://hypotheticalurl1.png",
"http://hypotheticalurl2.png",
"http://hypotheticalurl3.png",
"http://hypotheticalurl4.png",
"http://hypotheticalurl5.png",
"http://hypotheticalurl6.png",
"http://hypotheticalurl7.png",
"http://hypotheticalurl8.png",
"http://hypotheticalurl9.png",
"http://hypotheticalurl10.png",
"http://hypotheticalurl11.png",
"http://hypotheticalurl12.png",
//...blah blah blah
// these are all dynamically created so I won't know what is the last number on the list
};
这阵将最终被用于获取使用的应用程序从我的服务器映像。它的工作原理，但迄今为止，这只是硬codeD的URL。我想的URL是动态的，随着图像的数量将从一天一变。
This array will eventually be used to get the images from my server using the app. It works so far but that's only with hardcoded URLs. I would like the URLs to be dynamic, as the number of images will change from day to day.
我怀疑该正则表达式将在Java中工作得很好，但我还是那句话不是专家。正想着，也许就产生现有值的列表，服务器端的编写脚本并以某种方式解析，与Android应用程序。
I'm doubting that regex will work well in Java but then again I'm no expert. Was thinking of perhaps writing a script on the server end that generates a list of existing values and somehow parsing that with the android app.
任何人都可以点我在正确的方向？先谢谢了。
Can anyone point me in the right direction? Thanks in advance.
澄清：
该阵列不具备的应用程序运行时进行动态调整。
The array doesn't have to be dynamically sized while the app is running.
我需要一种方法来读取现有的图像列表中远程目录，并通过这些信息可以在运行时自动填充阵列。
I need a way to read the list of existing images in a remote directory and pass that information to populate the array automatically at runtime.
解决的

大家好，感谢您的帮助。很抱歉，如果我不太清楚。
Guys, thanks for the help. Sorry if I wasn't clear enough.
我已经找到一种方法来做到这一点。基本上，这是相当简单，这是code的一个额外的行追加到shell脚本在服务器端在它生成的图像，同时生成图像存在的URL的文本列表。
I've found a way to do it. Basically it was rather simple, which was to append an extra line of code to the shell script on the server end to generate a text list of existent image URLs at the same time that it generates the images.
在那之后，我使用的应用程序的BufferedReader和OpenStream的结合到远程文本文件解析成一个字符串数组。
After that, I used a combination of BufferedReader and openStream on the app to parse the remote text file into a String array.
