I have a String like this:
[["123","Albert","foo"],["456","Mark","bar"],["789","Jackson","baz"]]
How can I do to turn it into a corresponding array?
I get this response from a HttpPost in Java (Android).
Thanks in advance

3Looks like json, use a json parser.Sotirios Delimanolis– Sotirios Delimanolis2014-02-22 04:56:04 +00:00Commented Feb 22, 2014 at 4:56

The error is pretty descriptive. You're trying to get a json object from a json array. That doesn't make sense. Get a json array instead.Sotirios Delimanolis– Sotirios Delimanolis2014-02-22 05:03:05 +00:00Commented Feb 22, 2014 at 5:03

Suppose that in the table of the database, the columns are: id, name, nick try { String s = ""; JSONArray jArray = new JSONArray(result); for (int i=0;i<jArray.length();i++) { JSONObject json = jArray.getJSONObject(i); s = s + "Id: " + json.getString("id")+"\n"+ "Name: " + json.getString("name")+"\n"+ "Nick: " + json.getString("nick")+"\n\n"; } resultView.setText(s); } catch(Exception e) { Log.e("Log", "Error parsing JSON :("+e.toString()); }candlejack– candlejack2014-02-22 05:06:15 +00:00Commented Feb 22, 2014 at 5:06

Try this.
JSONArray new_array = new JSONArray(string);
for(int i =0; i < new_array.length(); i++){
JSONArray arr = new_array.getJSONArray(i);
for(int j =0; j < arr.length(); j++){
Log.v("result--",""+arr.getString(j));
}
}

Is there a way to make it a regular two-dimensional array? Because I need to manipulate the indices Or with JSON I can manipulate indexes? To display something like: s=s + "Id :"+arr[0]+"\n"+ "Name :"+arr[1]+"\n"+ "Nick :"+arr[2]+"\n\n";

Done! not arr[index] Is arr.get(index) :D
Use GSON
like:
Gson gson = new Gson();
String[][] myTypes = gson.fromJson(str, String[][].class);
search for more example of how to use GSON library.

In your format you have to fetch your data for JSONArray instead of JSONObject.
So you have to use this which make sense
JSONArray jArray = new JSONArray(yourResponsestr);
for(int i =0; i < jArray .length(); i++){
JSONArray arr = myarray.getJSONArray(i);
for(int j =0; j < myarray.length(); j++){
Log.v("Response Array -->",""+arr.getString(j));
}
}
