How can I create a JSON with this format in Android: Since the API that I will be passing will parse JsonArray then the object. Or would it be okay if just to pass a json object? Since I will just have to insert 1 transaction per service call.
{
"student": [
{
"id": 1,
"name": "John Doe",
"year": "1st",
"curriculum": "Arts",
"birthday": 3/3/1995
},
{
"id": 2,
"name": "Michael West",
"year": "2nd",
"curriculum": "Economic",
"birthday": 4/4/1994
}
]
}
What I know is only the JSONObject. Like this one.
JSONObject obj = new JSONObject();
try {
obj.put("id", "3");
obj.put("name", "NAME OF STUDENT");
obj.put("year", "3rd");
obj.put("curriculum", "Arts");
obj.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Any ideas. Thanks

You should use JSONObject.put method
https://developer.android.com/reference/org/json/JSONObject.html#put(java.lang.String,%20double)
JSONObject jsonResult = new JSONObject();
try {
jsonResult.put("clave", "valor");
jsonResult.put("username", "iesous");
jsonResult.put("password", "1234");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d("DEV","jsonResult->"+jsonResult);
Map<String, String> params = new HashMap<String, String>();
//** Temp array
List<String[]> tmpArray = new ArrayList<>();
tmpArray.add(new String[]{"b001","book1"});
tmpArray.add(new String[]{"b002","book2"});
//** Json Array Example
JSONArray jrrM = new JSONArray();
for(int i=0; i<tmpArray.size(); i++){
JSONArray jrr = new JSONArray();
jrr.put(tmpArray.get(i)[0]);
jrr.put(tmpArray.get(i)[1]);
jrrM.put(jrr);
}
//Json Object Example
JSONObject jsonObj = new JSONObject();
try {
jsonObj.put("plno","000000001");
jsonObj.put("rows", jrrM);
}catch (JSONException ex){
ex.printStackTrace();
}
// Bundles them
params.put("user", "guest");
params.put("tb", "book_store");
params.put("action","save");
params.put("data", jsonObj.toString());
// Now you can send them to the server.
Here's a simpler (but not so short) version which doesn't require try-catch:
Map<String, String> data = new HashMap<>();
data.put("user", "[email protected]");
data.put("pass", "123");
JSONObject jsonData = new JSONObject(data);
If you want to add a jsonObject into a field, you can do this way:
data.put("socialMedia", (new JSONObject()).put("facebookId", "1174989895893400"));
data.put("socialMedia", (new JSONObject()).put("googleId", "106585039098745627377"));
Unfortunately it needs a try-catch because of the put() method.
IF you want to avoid try-catch again (not very recommended, but it's ok if you can guarantee well formated json strings), you might do this way:
data.put("socialMedia", "{ 'facebookId': '1174989895893400' }");
You can do the same about JsonArrays and so on.
Cheers.
public JSONObject makJsonObject(int id[], String name[], String year[],
String curriculum[], String birthday[], int numberof_students)
throws JSONException {

JSONArray jsonArray = new JSONArray();
for (int i = 0; i < numberof_students; i++) {
obj = new JSONObject();
try {
obj.put("id", id[i]);
obj.put("name", name[i]);
obj.put("year", year[i]);
obj.put("curriculum", curriculum[i]);
obj.put("birthday", birthday[i]);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
jsonArray.put(obj);
}
JSONObject finalobject = new JSONObject();
finalobject.put("student", jsonArray);
return finalobject;
}
It's too late to answer, sorry about it, for creating the below body:
{
"username": "?Rajab",
"email": "[email protected]",
"phone": "+93767626554",
"password": "123asd",
"carType": "600fdcc646bc6409ae97e2ab",
"fcmToken":"lljlkdsajfljasldfj;lsa",
"profilePhoto": "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg",
"documents": {
"DL": [
{
"_id": "5fccb687c5b4260011810125",
"uriPath": "https://webfume-onionai.s3.amazonaws.com/guest/public/document/326634-beats_by_dre-wallpaper-1366x768.jpg"
}
],

You can create dynamically like the below code:
JSONObject jsonBody = new JSONObject();
try {
jsonBody.put("username", userName);
jsonBody.put("email", email);
jsonBody.put("phone", contactNumber);
jsonBody.put("password", password);
jsonBody.put("carType", carType);
jsonBody.put("fcmToken", "lljlkdsajfljasldfj;lsa");
jsonBody.put("profilePhoto", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg");
JSONObject document = new JSONObject();
try {
document.put("DL", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("Registration", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("Insurance", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("CarInside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
document.put("CarOutside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
} catch (JSONException e) {
e.printStackTrace();
}
jsonBody.put("documents", document.toString());
Log.i("MAHDI", "Hello: Mahdi: Data: " + jsonBody);
} catch (JSONException e) {
e.printStackTrace();
}
And the createDocument method code:
public JSONArray createDocument(String id, String imageUrl) {
JSONObject dlObject = new JSONObject();
try {
dlObject.put("_id", id);
dlObject.put("uriPath", imageUrl);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray dlArray = new JSONArray();
dlArray.put(dlObject);
return dlArray;
}
JSONObject obj = new JSONObject();
try {
obj.put("id", "3");
obj.put("name", "NAME OF STUDENT");
obj.put("year", "3rd");
obj.put("curriculum", "Arts");
obj.put("birthday", "5/5/1993");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray js=new JSONArray(obj.toString());
JSONObject obj2 = new JSONObject();
obj2.put("student", js.toString());
Have been struggling with this till I found out the answer:
Use GSON library:
Gson gson = Gson();
String str_json = gson.tojson(jsonArray);`
Pass the json array. This will be auto stringfied. This option worked perfectly for me.
You can create a a method and pass paramters to it and get the json as a response.
private JSONObject jsonResult(String Name,int id, String curriculum) throws JSONException {
JSONObject json = null;
json = new JSONObject("{\"" + "Name" + "\":" + "\"" + Name+ "\""
+ "," + "\"" + "Id" + "\":" + id + "," + "\"" + "Curriculum"
+ "\":" + "\"" + curriculum+ "\"" + "}");
return json;
}
I hope this will help you.
