Android Dynamic Array

Question
I am parsing an XML file through Android Pull Parser technique. First, have a look at the below XML file:
<childs>
<students>
<name> hello </name>
<address> xyz </address>
</stdents>
<students>
<name> abc </name>
<address> def </address>
</stdents>
</childs>
Consider that I'm parsing the above file. Now, my problem is that I want to create a separate array for name and address. So while parsing, I want to store 1st student's data in name[0]
and address[0]
and the next student's data in name[1]
and address[1]
. In short, array size is extending as more data is parsed.
Is there any way to do so? I mean to create a dynamic extendable array? Or if there is another way to do so then please help me to fight with this problem.
Solution
You could use Vector<String>
and then (if you need an array) copy the data to array(s) using toArray
method.
Vector<String> v = new Vector<String>();
for (int i=0; i<10; i++)
v.add(new String(Integer.toString(i)));
Object s[] = v.toArray();
for(int i=0; i<10; i++)
str = s[i].toString();
Another option:
String a[] = {};
v.toArray(a);
OTHER TIPS
You use and List array like this
List<String> name=new ArrayList<String>();
List<String> address=new ArrayList<String>();
name.add(StudyParser.getValue(eimg, "name"));
address.add(StudyParser.getValue(eimg,"address")
where StudyParser.getValue(); is method which u call to get data
