Over here you are setting settext to spinner_txt instead of spinner. I wonder how is your setText is getting called.

String spinnertxt=spinner.getText.toString;

You are getting NullPointerException because your spinner textview does not contain any text and so, snippertxt is null and you are trying to get length of a null object.

Try this:-

spinner.setText(name);
String spinnertxt=spinner.getText.toString;

android:focusable="false"
            android:clickable="true"
            android:focusableInTouchMode="false"
