Prompt Detail:

Yes, it's possible to have a text view with pre-existing text and placeholders for the user to fill in their name and surname.

One way to achieve this is by using SpannableStringBuilder to create a string with placeholders for the user's name and surname, and then setting it as the text for the TextView.

Here's an example code snippet:

kotlin
val textView = findViewById<TextView>(R.id.textView) val placeholder = "Name Surname" val text = "Please enter your $placeholder below:" val spannable = SpannableStringBuilder(text) val startIndex = text.indexOf(placeholder) val endIndex = startIndex + placeholder.length val editable = Editable.Factory.getInstance().newEditable(placeholder) spannable.setSpan(editable, startIndex, endIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE) textView.text = spannable

In the above code, we first get a reference to the TextView using the findViewById() method. We then create a string with a placeholder for the user's name and surname, and set it as the text for the TextView.

Next, we create a SpannableStringBuilder from the text, find the index of the placeholder in the text, and create an Editable from the placeholder. We then set the Editable as a span on the SpannableStringBuilder at the index of the placeholder.

The resulting string with placeholders will be displayed in the TextView, and the user can tap on the placeholders to enter their name and surname. You can retrieve the text entered by the user using the getText() method on the Editable object.
