i have an adapter from which i am creating edittext for user to input data dynamically.

Now, i have to store the same in JSONObject in a key-value pair? how can i do it?

i am storing all the created edit text in a list

ArrayList<EditText> list = new ArrayList<>();

EDIT PART

i am adding edittext to list like this:

list.add(holder.editText);

EDIT PART -ENDS

this is my button click listener code:

addnewAcnt.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Toast.makeText(context, "INIT", Toast.LENGTH_SHORT).show();
                JSONObject jsonObject2 = null;
                for (int i = 0; i < count; i++)
                {
                    jsonObject2 = new JSONObject();
                    try
                    {
                        jsonObject2.put(String.valueOf(list.get(i).getHint()), String.valueOf(list.get(i).getText()));
                    }
                    catch (Exception e)
                    {
                        e.printStackTrace();
                        Log.e("JsonToSendError: ", String.valueOf(e));
                    }

                    Log.e("JsonToSend: ", String.valueOf(jsonObject2));
                }
            }
        });

I am getting data in Log as:

2020-10-05 15:19:21.476 16462-16462/com.packagename E/JsonToSend:: {"Title":"StackOverFlow"}
2020-10-05 15:19:21.476 16462-16462/com.packagename E/JsonToSend:: {"URL":"www.stackoverflow.com"}
2020-10-05 15:19:21.476 16462-16462/com.packagename E/JsonToSend:: {"Username":"test"}
2020-10-05 15:19:21.476 16462-16462/com.packagename E/JsonToSend:: {"Password":"testtesttest"}

But, i need it to be in a single object like:

{"Title":"StackOverFlow", "URL":"www.stackoverflow.com", "Username":"test", "Password":"testtesttest"}

any help will be useful. Please

Because you creating new object in loop, try moving your jsonObject2 = new JSONObject(); before the loop.

About the last object, i'm not sure how do variable count value is changed. But if you are getting value from list, you should use that list count in your loop.

The code should be like this.

addnewAcnt.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Toast.makeText(context, "INIT", Toast.LENGTH_SHORT).show();
                JSONObject jsonObject2 = new JSONObject();
                for (int i = 0; i < list.size(); i++) // variable count to be your list (edit text) size.
                {
                    try
                    {
                        jsonObject2.put(String.valueOf(list.get(i).getHint()), list.get(i).getText().toString().trim());
                    }
                    catch (Exception e)
                    {
                        e.printStackTrace();
                        Log.e("JsonToSendError: ", String.valueOf(e));
                    }

                    Log.e("JsonToSend: ", String.valueOf(jsonObject2));
                }
            }
        });

i think you need define jsonObject2 = new JSONObject(); outside callback onclick. Hope this is helpful for you.

You create JSON object before the for loop and initialize in for loop. which is wrong

initialize a JSON object before FOR loop

Change this line jsonObject2 = null; to jsonObject2 = new JSONObject(); and remove from FOR Loop

addnewAcnt.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Toast.makeText(context, "INIT", Toast.LENGTH_SHORT).show();


                jsonObject2 = new JSONObject();


                for (int i = 0; i < count; i++)
                {
                    //jsonObject2 = new JSONObject();
                    try
                    {
                        jsonObject2.put(String.valueOf(list.get(i).getHint()), String.valueOf(list.get(i).getText()));
                    }
                    catch (Exception e)
                    {
                        e.printStackTrace();
                        Log.e("JsonToSendError: ", String.valueOf(e));
                    }

                    Log.e("JsonToSend: ", String.valueOf(jsonObject2));
                }
            }
        });
