How to add values to a string array in android

Question

I have a problem with my code,

I have a json array

                [{"Response":{"data":"sibin1"}},{"Response":{"data":"sibin2"}},
                              {"Response": {"data":"sibin3"}}]

And iam trying to extract the json data using the below code,Here i added only some parts of the coode

                 JSONArray  finalResult = new JSONArray(tokener);
                 int finalresultlengt=finalResult.length();
                 JSONObject json_data = new JSONObject();
      for (int i = 0; i < finalResult.length(); i++) 
            {

          json_data = finalResult.getJSONObject(i);
          System.out.println("json dataa"+json_data.names().toString());
          JSONObject menuObject = json_data.getJSONObject("Response");
          result=   menuObject.getString("data");   
             System.out.println(result);
              }

The code is worked very well

when the value of

                    i=0 ,result is sibin1
                    i=1 ,result is sibin2
                    i=2 ,result is sibin3

But my problem is , i need to store the result in a string array of length finalresultlength inside the given for loop, also i need to print the values in the string array in a for loop outside the given for loop if anybody knows please help me...........

Please refactor your question in order to make it readable. Fix indentation and try to put some punctuation. — Ivaylo Strandjev

Before your for loop declare a string array String[] dataStrings = new String[finalResultLength]; then as the last line of your for loop add dataStrings[i]=result; — rich200313

You could do this way as well.

Create an ArrayList of size 'finalresultlengt' and the add the values in.

 list.add(result);  // variable 'result' in your case is the value from JSON

If you have more values to be added, create a POJO class.

class POJO {
    private String dataVal;

    public void setDataVal(String dataVal) {
        this.dataVal = dataVal;
    }

    public String getDataVal() {
        return dataVal;
     }
 }

Then create an ArrayList of type POJO.

 ArrayList<POJO> list = new ArrayList<POJO>(finalresultlengt);

EDIT

JSONArray  finalResult = new JSONArray(tokener);
int finalresultlengt=finalResult.length();
JSONObject json_data = new JSONObject();
ArrayList<String> list = new ArrayList<String>(finalresultlengt);

for (int i = 0; i < finalResult.length(); i++) {
      json_data = finalResult.getJSONObject(i);
      System.out.println("json dataa"+json_data.names().toString());
      JSONObject menuObject = json_data.getJSONObject("Response");
      result=   menuObject.getString("data");
      list.add(result);   
 }

Populate values from ArrayList.

 for(String value : list) 
      System.out.println(value);
