spinner_button.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?>arg0, View view, int arg2, long arg3) {

            String selected_val=spinner_button.getSelectedItem().toString();

            Toast.makeText(getApplicationContext(), selected_val ,
                    Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

}

对于那些基于HashMap的旋转器:

((HashMap)((Spinner)findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString();

如果你在一个片段，一个适配器或一个类，而不是主活动，使用这个:

((HashMap)((Spinner)YourInflatedLayoutOrView.findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString();

这只是为了指导;你应该在onClick方法之前找到视图的id。

您必须使用索引和适配器来查找您拥有的文本

请看Spinner的例子

public class MyOnItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent,
        View view, int pos, long id) {
      Toast.makeText(parent.getContext()), "The planet is " +
          parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
    }

    public void onNothingSelected(AdapterView parent) {
      // Do nothing.
    }
}

Spinner spinner = (Spinner)findViewById(R.id.spinner);
String text = spinner.getSelectedItem().toString();

Spinner spinner = (Spinner) findViewById(R.id.yourspinnerid);
String text = spinner.getSelectedItem().toString();

spinner_button.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?>arg0, View view, int arg2, long arg3) {

            String selected_val=spinner_button.getSelectedItem().toString();

            Toast.makeText(getApplicationContext(), selected_val ,
                    Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

}
