Answer 1

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bt = findViewById(R.id.button);
        spinner = findViewById(R.id.sp_item);
        setInfo();
        spinnerAdapter = new SpinnerAdapter(this, arrayList);
        spinner.setAdapter(spinnerAdapter);



        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView parent, View view, int position, long id) {
                //first,  we have to retrieve the item position as a string
                // then, we can change string value into integer
                String item_position = String.valueOf(position);

                int positonInt = Integer.valueOf(item_position);

                Toast.makeText(MainActivity.this, "value is "+ positonInt, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onNothingSelected(AdapterView parent) {

            }
        });







note: the position of items is counted from 0.
