binding.spLength.setAdapter(new ArrayAdapter<>(context, R.layout.spinner_length_layout,spinnerItemsAmp));
binding.spLength.setSelection(0,false);
binding.spLength.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

@Override

if that doesn't work try

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, 
your_array, 
android.R.layout.simple_spinner_item);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_name.setAdapter(adapter);
