Question

I have implemented multiple(seven) spinners and populated them with three options: Yes, No, and Unknown. And “Unknown” is the default option. Now I want to know whether user clicked spinner or not. Since the default option can also be a valid answer, I could not work with getSelectedItemPosition() in Spinner class.

All I want to know is whether user clicked that particular spinner or not, so that I can generate alert message depending on this Info.

The first thing you should do is read the Spinners guide on the Android developer site. Having done that, you’ll find this handy example:

public class MySpinnerActivity extends Activity implements OnItemSelectedListener {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Spinner spinner = (Spinner) findViewById(R.id.spinner);
        spinner.setOnItemSelectedListener(this);
    }

    public void onItemSelected(AdapterView<?> parent, View view, 
            int pos, long id) {
        // An item was selected. You can retrieve the selected item using
        // parent.getItemAtPosition(pos)
    }

    public void onNothingSelected(AdapterView<?> parent) {
        // Another interface callback
    }
}
