So to load data to the spinner there are 2 ways.
Static data loading
First add the data to .xml file. Into string.xml or array.xml or anyname you want. I prefer to use array.xml. Inside it create string-array and add items to it.

<string-array name="gender_list">
<item>male</item>
<item>female</item>
<item>other</item>
</string-array>
Then in Spinner in layout/spinner_test.xml

<Spinner
android:id="@+id/spinnerGender"
android:layout_width="120dp"
android:layout_height="wrap_content"
android:entries="@array/gender_list"
/>
Thats it.
Dynamic data loading

customeList = listOf("male", "female", "other")
val dataAdapter =
ArrayAdapter<String>(context, R.layout.simple_spinner_item, customeList)
genderSpinner.adapter = dataAdapter

spinnerMunicipality.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
override fun onNothingSelected(adapterView: AdapterView<*>?) {
// no thing to do yet
}
override fun onItemSelected(
adapterView: AdapterView<*>?,
view: View?,
position: Int,
id: Long
) {
Log.d(TAG, "You selected ${adapterView?.getItemAtPosition(position).toString()}")
}
}
