Loading data to spinner with item click listener.

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

Adding Onclick Listner to Spinner

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()}")
      }
}
