检索parse.com数组和值添加到本地阵列（Android版） [英] Retrieve an array from parse.com and add the values to a local array (Android)

问题描述

我从parse.com在用户类被称为根的数组列，我想要从列数组对象，然后提取值（字符串）到一个数组在我的申请。

I have an array column called "Roots" in a user class from parse.com and I want to retrieve the array object from the column and then extract the values (strings) to an array in my application.

ParseUser.logInInBackground(user, password, new LogInCallback() {
                public void done(ParseUser user, ParseException e) {
                    if (user != null) {
                        // Hooray! The user is logged in.
                        startMenu();
                        String[] testStringArray = (String[])user.get("Roots");

我不知道，如果最后一行甚至可以。即使是这样，我不知道如何提取单个元素，并将它们设置为本地数组，我可以使用索引例如调用。

I'm not sure if the last line even works. Even if it does, I'm not sure how to extract the individual elements and set them to a local array that I can call on using an index e.g.

String myString = testStringArray[1]

或一些这样的。我曾尝试上述code的一些变化，我觉得我失去了一些东西根本。有没有人有我如何才能做到这一点的例子吗？
在此先感谢！

Or some such. I have tried a few variations of the above code and I think I am missing something fundamental. Does anyone have an example of how I can accomplish this? Thanks in advance!

推荐答案

使用的的ArrayList＆LT;弦乐＆GT; 而不是的String [] ，那么你就可以访问它，就像任何其他的ArrayList对象。

Use an ArrayList<String> instead of String[], then you can access it as you would any other ArrayList object.

ArrayList<String> testStringArrayList = (ArrayList<String>)user.get("Roots");
String myString = testStringArrayList.get(1);
