关于微调器和相应报警的Android教程

我正在构建一个药物交互和通知应用程序-对于一个部分，我需要选择一个微调器项，然后使用该微调器选项向CorresPond发出警报

到目前为止，我已经有了微调器的代码-问题是如何将警报代码添加到微调器的CorresPond中

public class Interactions extends Activity implements   OnItemSelectedListener {

    Spinner spinner;
    TextView showmed;
    private String[] state = {"Adalimumab",
            "Etanercept",
            "Tacrolimus",
            "Mycophenolic Acid",
            "Bicalutamide",
            "Darbepoetin alfa",
            "Ciclosporin",
            "Interferon beta-1a",
            "Triptorelin"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_interactions);
        System.out.println(state.length);
        showmed = (TextView) findViewById(R.id.showmed);
        spinner = (Spinner) findViewById(R.id.spinner);
        ArrayAdapter<String> adapter_state = new ArrayAdapter<String>(this,
                android.R.layout.simple_spinner_item, state);
        adapter_state

     .setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter_state);
        spinner.setOnItemSelectedListener(this);

    }

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