Problem displaying an expandable list android studio java

I have made a page allowing to see tools arranged in classes and subclasses (3rd floor).
The tools database is on a server, and I receive the data as JSON.
Everything was working fine until I added a number of tools (and therefore classes)
My tools appear several times without reason in classes that are not the right ones.
I checked the JSON, no problem.
Here are screenshots of the problem and the code that allows me to retrieve the data and send it to my adapter.
Thanks for your help.

I would like to have a correct display of the tools and their class. I don't have to have expandables list

Many objects to one Object using jolt

Hi working in Jolt transformation tool and getting know some in-depth details
Input
{
"characteristic": [
{
"name": "usageCharacteristicName",
"value": "availableBalance",
"#type": "usageCharacteristic",
"arrayIndex": "2"
},
{
"name": "usageCharacteristicValue",
"value": "2999.25",
"#type": "usageCharacteristic",
"arrayIndex": "2"
},
{
"name": "usageCharacteristicName",
"value": "Name",
"#type": "usageCharacteristic",
"arrayIndex": "0"
},
{
"name": "usageCharacteristicValue",
"value": "Jack",
"#type": "usageCharacteristic",
"arrayIndex": "0"
},
{
"name": "usageCharacteristicName",
"value": "Likes",
"#type": "usageCharacteristic",
"arrayIndex": "1"
},
{
"name": "usageCharacteristicValue",
"value": "Code",
"#type": "usageCharacteristic",
"arrayIndex": "1"
}
]
}
Jolt Spec :
[
{
"operation": "shift",
"spec": {
"characteristic": {
"*": {
"arrayIndex": {
"2": {
"#(2,value)": "data.queryBalance.accountBalance"
},
"0": {
"#(2,value)": "data.queryBalance.Name"
},
"1": {
"#(2,value)": "data.queryBalance.Likes"
},
}
}
}
}
}
]
Output :
{
"data" : {
"queryBalance" : {
"accountBalance" : [ "availableBalance", "2999.25" ],
"Name" : [ "Name", "Jack" ],
"Likes" : [ "Likes", "Code" ]
}
}
}
the Output i was getting is not good enough for me, want to do like String like bellow Expected.
Expected Output :
"availableBalance" : "2999.25",
"Name" : "Jack",
"Likes" : "Code"
how do i get like a String ?

I think this solve the problem
spec
[
{
//group keys and valeus for arrayIndex
"operation": "shift",
"spec": {
"characteristic": {
"*": {
"value": "newArray[#(1,arrayIndex)].#(1,name)"
}
}
}
},
{
//create a new object use a key and valeus matchs previous
"operation": "shift",
"spec": {
"newArray": {
"*": {
"usageCharacteristicValue": "#(1,usageCharacteristicName)"
}
}
}
}
]
output
{
"Name" : "Jack",
"Likes" : "Code",
"availableBalance" : "2999.25"
}

You need a modify transformation spec as well such as
[
{
// reduce to simple array "value" : [ "availableBalance", "2999.25" ] nested within an object
"operation": "shift",
"spec": {
"*": {
"*": {
"value": "&"
}
}
}
},
{
// combine components of the array so as to reform as a string
"operation": "modify-overwrite-beta",
"spec": {
"*": "=join(' : ',#(1,&))"
}
}
]
Edit: You can alternatively try the following for the new case :
[
{
// dissipate each array into different object with respect to arrayIndex values
"operation": "shift",
"spec": {
"*": {
"*": {
"value": "#(1,arrayIndex).&"
}
}
}
},
{
// combine components of each array colon-separatedly
"operation": "modify-overwrite-beta",
"spec": {
"*": {
"*": "=join(' : ',#(1,&))"
}
}
},
{
// convert to a unique array
"operation": "shift",
"spec": {
"*": {
"*": "&"
}
}
},
{
// combine components of each array comma-separatedly
"operation": "modify-overwrite-beta",
"spec": {
"*": "=join(' , ',#(1,value))"
}
}
]

I know how to do it by another library Josson. You may consider to use it.
https://github.com/octomix/josson
Deserialization
Josson josson = Josson.fromJsonString(inputJSON);
Transform to an array of string
JsonNode node = josson.getNode(
"characteristic" +
".group(arrayIndex)" +
".concat(elements[name='usageCharacteristicName'].value" +
" ,' : '" +
" ,elements[name='usageCharacteristicValue'].value)");
System.out.println(node.toPrettyString());
Output
[ "availableBalance : 2999.25", "Name : Jack", "Likes : Code" ]
Transform to a single string
String str = josson.getString(
"characteristic" +
".group(arrayIndex)" +
".concat(elements[name='usageCharacteristicName'].value" +
" ,' : '" +
" ,elements[name='usageCharacteristicValue'].value)" +
".join(', ')");
System.out.println(str);
Output
availableBalance : 2999.25, Name : Jack, Likes : Code
Transform to a map
JsonNode node = josson.getNode(
"characteristic" +
".group(arrayIndex)" +
".map(elements[name='usageCharacteristicName'].value::elements[name='usageCharacteristicValue'].value)" +
".mergeObjects()");
System.out.println(node.toPrettyString());
Output
{
"availableBalance" : "2999.25",
"Name" : "Jack",
"Likes" : "Code"
}
Transform to a map with sorted "arrayIndex" as key
JsonNode node = josson.getNode(
"characteristic" +
".group(arrayIndex)" +
".sort(arrayIndex)" +
".map(arrayIndex.prepend('arrayIndex')::" +
" concat(elements[name='usageCharacteristicName'].value" +
" ,' : '" +
" ,elements[name='usageCharacteristicValue'].value))" +
".mergeObjects()");
System.out.println(node.toPrettyString());
Output
{
"arrayIndex0" : "Name : Jack",
"arrayIndex1" : "Likes : Code",
"arrayIndex2" : "availableBalance : 2999.25"
}

How do I parse this JSON object to get a list of recipe objects that I can then use?

So I am incredibly new to Java and am needing help parsing a JSON response. I already have the method in which I am using to do so, but need help figuring out what exactly I am doing wrong.
I am using an API to retrieve recipes from a site. I am trying to get a list of recipes ("hits" in this case I assume?) that I can then show to the user.
Obviously I need the recipe name ("label" in this case) and other information. Can anyone help me?
Here is the response api response I am getting:

This is currently the method I am using to parse the JSON object:
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
#Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
//JSONObject jsonData1 = new JSONObject(myResponse);
JSONObject Jobject = null;
try {
Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray Jarray = null;
try {
Jarray = Jobject.getJSONArray("hits");
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object;
try {
object = Jarray.getJSONObject(i);
try {
JSONArray Recipe = object.getJSONArray("recipe");
}catch (JSONException e){
e.printStackTrace();
}
for (int j = 0; j < Jarray.length(); j++){
JSONObject object2 = null;
try {
object2 = Jarray.getJSONObject(j);
String Name = object2.getString("label");
String Photo = object2.getString("image");
Log.d("rec_query", " " + Photo);
}catch (JSONException e){
e.printStackTrace();
Log.d("response6:", e.toString());
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
});
}
}
});
return null;
}
}
NOTE THE {} {} are just different recipes...it wouldnt fit the whole response
At the moment, when I try to print my variables in the Log, I am getting a message that says the variable is empty (the variable that i used to store the different recipes/"hits".

Your response seems incomplete, it's not in the correct JSON format，Provide the right format and I'll try to help you

String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
like this,and neep to import com.alibaba.fastjson
But i dont`t know if you can use fastjson

Convert Array of key=value String to JSON in JAVA

I have multi Array key value string
For Example:
{

},
prid=9.0,
name=abc,
prqt=1.0,

},
{

name=abc,
prid=10.0,

In can't get String value in third Arraylist "list":[ because is same name with Second ArrayList "list":[.
But when I Toast Second ArrayList I see Second,third Arraylist but I can't get String third value and show nothing in Log or my listView or Toast String Value
how can I access Packname?

you have no Packname in your first array, please revise this
for (int j = 0; j < jsonArraylist.length(); j++) {
JSONObject objectlist = jsonArraylist.getJSONObject(j);
if(objectlist.has("Packname")){
String Packname= objectlist.getString("Packname");
Log.i("Log", "SHOW Packname " + Packname);
listmain.add(new ListViewMain(Packname));
}
}
adapter.notifyDataSetChanged();
please try this
