It looks like you are looking for how to pass data between activities. First, you will have to make your NumberPicker global:

private Spinner mSpinner;
private NumberPicker mNumberPicker;

With this in mind, you can send your data to a new Activity with an Intent like so:

Intent intent = new Intent(v.getContent(), ListItem.class);
intent.putExtra(ListItemActivity.EXTRA_MAJOR, mSpinner.getSelectedItem().toString());
intent.putExtra(ListItemActivity.EXTRA_INT, mNumberPicker.getValue());
startActivityForResult(intent, 0);

Then you can receive the data in your new Activity with getIntent():

public class ListItemActivity extends AppCompatActivity {

    public static final String EXTRA_MAJOR = "list_item:major";
    public static final String EXTRA_INT = "list_item:int";

    private int mInteger;
    private String mMajor;

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

        Intent intent = getIntent();

        mMajor = intent.getStringExtra(EXTRA_MAJOR);
        mInteger = intent.getIntExtra(EXTRA_INT);
    }

}
