Final answer:
To get the selected value from a spinner in Android Kotlin, you should use the getItemAtPosition method within the onItemSelectedListener of the Spinner, and convert the Object returned by this method to the appropriate data type.
Step-by-step explanation:
To get the selected value of a spinner in Android using Kotlin, you can use the getItemAtPosition() method, which retrieves the value as an Object. You can then convert this to the appropriate data type. First, ensure that you have set an Adapter to the Spinner and defined the onItemSelectedListener for the Spinner. Here's a quick example:
spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
override fun onItemSelected(parent: AdapterView<?>, view: View, position: Int, id: Long) {
val selectedValue = parent.getItemAtPosition(position).toString()
// Use selectedValue here
}
override fun onNothingSelected(parent: AdapterView<?>) {
// Optional: Do something when nothing is selected
}
}
Replace spinner with the ID of your Spinner view. When an item is selected, the onItemSelected method is called, and the selected value is obtained as a String from the Adapter.
