Spinner in Android

Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        sp=(Spinner)findViewById(R.id.spinner);

        ArrayAdapter<String> arrayAdapter=new ArrayAdapter<String>(MainActivity.this,R.layout.text,citys);

        sp.setAdapter(arrayAdapter);

        sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override

            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                Toast.makeText(MainActivity.this, "Selected City is : "+citys[position], Toast.LENGTH_SHORT).show();

            }


            @Override

            public void onNothingSelected(AdapterView<?> parent) {


            }

        });
