How to get Result of LinkedHashMap within Inverted commas

Question

I am developing an Android app in which I have to send LinkedHashMap results by API but the problem what I am getting is format of result is different. How can I put keys and values both in inverted commas?

I'm getting result like this:

list: {0=816444014066, 1=747083010945, 2=816444010969}

And I want result like this:

list: {"0" : "816444014066","1" : "747083010945","2" : "816444010969"}

How to change the format of result?

How can you send API response as LinkedHashMap? I think API response is either JSON or XML. — Haresh Chhelana, Nov 29 '17 at 08:04

Use My Answer. It worked for me.

LinkedHashMap<String, String> data = new LinkedHashMap<String, String>();
// Instantiate a new Gson instance.
        Gson gson = new Gson();

        // Convert the ordered map into an ordered string.
        String json = gson.toJson(data, LinkedHashMap.class);

        // Print ordered string.
        Log.e("list", ""+json); //  {"0" : "816444014066","1" : "747083010945","2" : "816444010969"}

To get the quotes you need to make your keys and values String in your LinkedHashMap

Edit:

maybe what you need is already provided in this answer

both are already String @Peppermint – Abhishek kumar Nov 29 '17 at 08:07
how do you convert your linkedhashmap to string, just by using `toString()``method? – Peppermint Paddy Nov 29 '17 at 08:11

In Java you can put quotes to String with :

String value = " \"1\" ";

You could do it like this:

Map<String, String> linkedmap = new LinkedHashMap<>();
linkedHashMap.put(setQuotes("1"), setQuotes("5445454"));

public static String setQuotes(String value){
     String result = "";
     if(!value.isEmpty()){
          result = "\"" + value + "\"";   
     }
     return result;
}

If you print it in the console, it returns:

{"1"="5445454"}

I think that possibility is to create your own Map class that extends LinkedHashMap and to create and implement in it method with behavior similar to behavior of toString() method. This link might help you to get started with implementation of that method:
