如何在另一个活动中访问变量值.在我的例子中,我有一个字符串变量项,其值是微调器选择的值.如何在不使用Intent的情况下在另一个活动中访问此变量？

  public class LoginScreen extends Activity {

      Spinner sp;
String item;


      Spinner sp = (Spinner) findViewById(R.id.lgnspinner);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.network_array,
            android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    sp.setAdapter(adapter);

    sp.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
            item = (String) parent.getItemAtPosition(position);



        public class AgAppMenu extends Activity {
