Button setOnClickListener method is not invoked

The below is the sample code I'm trying to get the selected value from spinner on setOnClickListener method for the Button validateUser.

    public class MainActivity extends Activity implements  AdapterView.OnItemSelectedListener {
      private Button validateUser;
      private Spinner userTypeSpinner;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        userTypeSpinner=(Spinner)findViewById(R.id.userTypeSpinner);
        validateUser= (Button) findViewById(R.id.userValidate);

        validateUser.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(getApplicationContext(), "Button is Selected", Toast.LENGTH_SHORT);
            }
        });



        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                R.array.userTypeArray, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        userTypeSpinner.setAdapter(adapter);
        userTypeSpinner.setOnItemSelectedListener(this);
    }

    @Override
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
        String item = adapterView.getItemAtPosition(i).toString();

        Toast.makeText(adapterView.getContext(), "Selected: " + item, Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> adapterView) {

    }
}

But you still not going to be able to use that spinner inside your button setOnClickListener.

validateUser.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast.makeText(getApplicationContext(), "Button is Selected", Toast.LENGTH_SHORT);
        }
    });

Toast needs to be shown. use .show() at the end.

Toast.makeText(getApplicationContext(), "Button is Selected", Toast.LENGTH_SHORT).show();
