In what cases does the content of the EditText component remain unchanged after saving or updating?

The content of the EditText component in Android remains unchanged after saving or updating if:

• Saving state is not implemented (for example, during screen rotation or activity recreation).
• The mechanism for saving and restoring state (onSaveInstanceState / onRestoreInstanceState) is not used.
• When updating data in EditText programmatically, the text is not changed.

To preserve the content of EditText during configuration changes, you need to override the state-saving methods or use ViewModel to store data.

Example of saving state:

override fun onSaveInstanceState(outState: Bundle) {
    super.onSaveInstanceState(outState)
    outState.putString("editTextContent", editText.text.toString())
}

override fun onRestoreInstanceState(savedInstanceState: Bundle) {
    super.onRestoreInstanceState(savedInstanceState)
    val content = savedInstanceState.getString("editTextContent")
    editText.setText(content)
}
