嗨在我的應用程序中我設計了一個彈出式註冊頁面。我添加了學生姓名，班級，學號，父母名稱，電話號碼。彈出在android中的微調框架
registration.java：
public class PopupRegistration extends Activity implements OnItemSelectedListener {
private String[] state = { "class","1", "2", "3",
"4", "5", "6", "7","8", "9"};
private String[] state1 = { "RollNO","1", "2", "3",
"4", "5", "6", "7","8", "9"};
public String log;

List<String> list;
GSfeedback cn;
EditText etName,etClass,etrollno,etparentname,etphno;

Spinner spinnerOsversions,spinnerOsversions1;
String PHONE_REGEX;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popup_registration);
db = new DatabaseHandlers(this);
etName=(EditText)findViewById(R.id.etName);

finish();

startActivity(nextScreen);

});
}
public void onItemSelected(AdapterView<?> parent, View view, int position,long id) {
spinnerOsversions.setSelection(position);
String selState = (String) spinnerOsversions.getSelectedItem();
etClass.setText("" + selState);

private boolean validate(){

在此，我用微調的兩個領域，即類，並沒有推出針對一個我寫這樣的，但它的代碼沒有working.before我拿了一個微調，並申請上課，它正常工作，但只有我使用相同的代碼滾沒有它不工作任何人都可以告訴我我做錯了什麼，並解決它。
謝謝，
_not working_意味着什麼是你的問題？ –
點擊註冊按鈕後顯示在我的微調僅適用類請填寫空白字段驗證現在正在它不工作是什麼問題可以請你告訴我 – user3437313
