You can use JSONObject its default supplied with android SDK:
String json = "some JSON";
JSONObject jsonObject = new JSONObject(json);
Than you can use methods like
getBoolean(String key)
getDouble(String key)
etc
Or you can use google gson library which is in my opinion better, but you will need to include it as dependency in gradle.
There is github for the Gson.
There is Gson API

Use Gson library . Best way to parse the responses.Your can user GsonFormat plugin to generate the model for response.

Have a look on gson. It's a easy serializer for json.

It's my pleasure to answer your question.
You can do like this.
try {
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonArray = jsonObject.getJSONArray("getdetailsasanas");
for (int i = 0; i < jsonArray.length(); i++) {
String asanaid = jsonArray.getJSONObject(i).getString("asanaid");
String asananame = jsonArray.getJSONObject(i).getString("asananame");
String duration = jsonArray.getJSONObject(i).getString("duration");
String imageurl = jsonArray.getJSONObject(i).getString("imageurl");
String imageversion = jsonArray.getJSONObject(i).getString("imageversion");
String videourl = jsonArray.getJSONObject(i).getString("videourl");
String videoversion = jsonArray.getJSONObject(i).getString("videoversion");
JSONArray StepsForAsanaArray = jsonArray.getJSONObject(i).getJSONArray("StepsForAsana");
for (int j = 0; j < StepsForAsanaArray.length(); j++) {
String stepnumber = jsonArray.getJSONObject(j).getString("stepnumber");
String stepdesc = jsonArray.getJSONObject(j).getString("stepdesc");
String stepimg = jsonArray.getJSONObject(j).getString("stepimg");
String stepimgeversion = jsonArray.getJSONObject(j).getString("stepimgeversion");
String imgethumbversion = jsonArray.getJSONObject(j).getString("imgethumbversion");
String imgethumburl = jsonArray.getJSONObject(j).getString("imgethumburl");
}
}
} catch (JSONException e) {
e.printStackTrace();
}

Use like with this code:
JSONArray getdetailsasanas = new JSONArray(stringData);
for (int p = 0; p < getdetailsasanas.length(); p++) {
try {
JSONObject data = getdetailsasanas.getJSONObject(p);
JSONObject asanaid = data.getJSONObject("asanaid");
JSONObject stepnumber = data.getJSONObject("stepnumber");
JSONObject stepnumber = data.getJSONObject("stepnumber");
//get data from objetcs
String asananame = asanaid.getString("asananame");
int duration = asanaid.getInt("duration");
String imageurl = asanaid.getString("imageurl");
} catch (JSONException e) {
e.printStackTrace();
}
}

array.put(obj);
}
how we can convert json string to normal string ? please give me answer.

You can used toString function for this.
array.toString()

JSONObject obj = new JSONObject(yourstring);
String x = obj.getString("x");

Use this code, may help you.
JSONObject json = new JSONObject();
//put your values
json.toString();

clear your question please
JsonObject to String use:
json.toString();
String to JsonObject:
String data= "Json format data";
JsonObject obj=new JsonObject(data);

at first you should send JSONArray Data inside JSONObject then via below codes get and set your list
public void onResponse(String response) {
try {
JSONObject responseJsonObject = new JSONObject(response);
JSONArray arrayJsonObject = responseJsonObject.getJSONArray("items");
for (int i = 0; i < arrayJsonObject.length(); i++) {
JSONObject jsonObject = arrayJsonObject.getJSONObject(i);
//Or do somthing with Array Datas
}
}
}
if your array not have name :
JSONArray jsonArray = new JSONArray(String_Result);

I have,
[{"GroupPosition":0,"ChildPosition":0},{"GroupPosition":0,"ChildPosition":1},{"GroupPosition":1,"ChildPosition":0}]
How do I split them into:
GroupPosition:
[0,0,1] or {0,0,1}
ChildPosition:
[0,0,0] or {0,0,0}

Your input is in json format. Consider my code is sample.
private static ArrayList<String> array_1 = new ArrayList<String>();;
String json = [{"GroupPosition":0,"ChildPosition":0},{"GroupPosition":0,"ChildPosition":1},{"GroupPosition":1,"ChildPosition":0}];
JSONArray leagues = new JSONArray(json);
for (int i = 0; i < leagues.length(); i++) {
JSONObject obj = leagues.getJSONObject(i);
array_1.add(obj.getString("GroupPosition"));
}

How to convert object array to string array in Java

I need to convert a string stored like,
textView.setText(myVar);
Here
myVar = "23,45,64,78";
I would like it to convert into array like below,
int[] xAxis = new int[]{23,45,64,78};
How can I achieve this? Thanks

Try this:
String arr = "[23,45,64,78]";
String[] items = arr.replaceAll("\\[", "").replaceAll("\\]", "").split(",");
int[] results = new int[items.length];
for (int i = 0; i < items.length; i++) {
try {
results[i] = Integer.parseInt(items[i]);
} catch (NumberFormatException nfe) {};
}
