                        android:id="@+id/etgen"
                        android:entries="@array/gender"
                        android:paddingRight="10dp"
                        android:paddingLeft="10dp"

Answer 1

What I noticed here about Spinner that in XML we are not able to disable it using

 android:enabled='false'

It's not possible to enable/disable a Spinner in XML (yet). To do so you have to do it in code.

spinner.setEnabled(false);

If anyone knows any specific reason why so, they are welcome to edit.

You have to disable it programmatically.

spinner.isEnabled = false

You can also change the color of it to give the disabled look like mentioned below. It will display the spinner in gray color.

 spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
        override fun onNothingSelected(p0: AdapterView<*>?) {
        }

        override fun onItemSelected(parent: AdapterView<*>?, p1: View?, p2: Int, p3: Long) {
            (parent?.getChildAt(0) as? TextView)?.setTextColor(Color.GRAY)

        }
    }

The above code is written in Kotlin. If you find any difficulty I can convert it to Java as well.
