Android Getting Survey Results In PieChart from JSON Need Roadmap

I created a piechart view with help of Android Developer site. I also store my survey results on my MySQL database. My JSON output is like this:

{"results":[{"CandidateNo":"110","VoteCount":"3"},{"CandidateNo":"1124","VoteCount":"1"}]}

In Android, I used this to getting results. 

 for (int i = 0; i < result.length(); i++) {
                        JSONObject c = sonuc.getJSONObject(i);

                        String CandidateNo = c.getString(TAG_NO);
                        String Result = c.getString(TAG_RESULT);

                        pie.addItem(TAG_NO,TAG_RESULT, color);


                    }

addItem method is like this:

 public int addItem(String label, float value, int color)

So the result value is float. But my TAG_RESULT is String. So it doesn't accept. What should i do about this, is my approach wrong?

Use Float.valueOf(String) to convert string to float.
