Get the data from dynamic created Edittext

i have created some dynamic textviews. I want to get the text of the textviews when the user clicks on the next button. I have written the logic to create the EditText in my Adapter class. I have a button in my activity on Click of the button i want to fetch all the text from the text views that was created dynamically in my adapter class.

 if(input_type=="text")
    {
        holder.question.text=questionsList!![position].question
        val tableRow = TableRow(context)
        tableRow.layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
        var ansEditText = EditText(context)
        ansEditText.setPadding(5,5,5,15)
        ansEditText.setHint("Answer")
        ansEditText.setTextColor(Color.parseColor("#000000"))
        ansEditText.textSize= 20F
        tableRow.addView(ansEditText)
        holder.linearQuestionanire.addView(tableRow)
      }

So basically you have model something like Question.

One option is add field answer in to that model and add listener on your EditText onTextChange(), after text has changed save changes to your Question.answer field. When using this approach you will have already mapped question-answer list.

Also Pair<Question, Answer?> is good use case I think

it might look something like this

  if (input_type == "text") {
            val question = questionsList!![position]
            holder.question.text = question.question
            val tableRow = TableRow(context)
            tableRow.layoutParams = ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
            var ansEditText = EditText(context)
            ansEditText.setPadding(5, 5, 5, 15)
            ansEditText.setHint("Answer")
            ansEditText.setTextColor(Color.parseColor("#000000"))
            ansEditText.textSize = 20F
            tableRow.addView(ansEditText)
            holder.linearQuestionanire.addView(tableRow)

            ansEditText.addTextChangedListener(object : TextWatcher {
                override fun afterTextChanged(s: Editable?) {
                    question.answer = s.toString()
                }

                override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
                    // Empty
                }

                override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
                    // Empty
                }
            })
        }

also don't forget to remove TextWatcher so it would not cause memory leak

There are multiple ways you could approach this problem.

  1. You could save the text in the textviews in a string array when you dynamically create them.
  2. You could keep track of the textviews and get the text using textView.getText().
  3. You could keep track of the ids of the textviews, get the textview using 'findViewById()` and then get the text from the textview.

The most appropriate choice would obviously depend on your code, future considerations and other such criteria.
