how to convert the data stored in string to string array

I'm parsing an url using json. I'm getting the value of each tag and storing it in a string using getString in a for-loop.

What I want is to store the String value into a String array. I'm a noob as far as android development is concerned.

Below is the code:

JSONObject json = JsonFunctions.getJSONfromURL("http://www.skytel.mobi/stepheniphone/iphone/stephenFlickr.json");

try {
  JSONArray boombaby=json.getJSONArray("items");

  for(int i=0;i<boombaby.length();i++) {
     JSONObject e = boombaby.getJSONObject(i);
     mTitleName=e.getString("title");
     String mTitleImage=e.getString("image");
  }
}

List<String> titles = new ArrayList<String>();
List<String> images = new ArrayList<String>();
for (int i = 0; i < boombaby.length(); i++) {
    JSONObject e = boombaby.getJSONObject(i);
    titles.add(e.getString("title"));
    images.add(e.getString("image"));
}

and then convert list to array:

String[] titleArray = (String[])titles.toArray(new titles[titles.size()]);

String[] imageArray = (String[])images.toArray(new titles[images.size()]);

My solution:

String[] convert2StringArr(String str)
{
    if(str!=null&&str.length()>0)
    {
        String[] arr=new String[str.length()];
        for(int i=0;i<str.length();i++)
        {
            arr[i]=new String(str.charAt(i)+"");
        }
        return arr;
    }
    return null;
}

Use a List to store your titles, and another to store your images. Or design a class holding two fields (title and image), and store instances of this class in a List:

List<String> titles = new ArrayList<String>();
List<String> images = new ArrayList<String>();
for (int i = 0; i < boombaby.length(); i++) {
    JSONObject e = boombaby.getJSONObject(i);
    titles.add(e.getString("title"));
    images.add(e.getString("image"));
}

Read the Java tutorial about collections. This is a must-know.
