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

Spinner返回数组的整数值。必须根据索引检索字符串值。

Spinner MySpinner = (Spinner)findViewById(R.id.spinner);
Integer indexValue = MySpinner.getSelectedItemPosition();

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。

在设置转轮适配器后，这段代码将有所帮助

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
            Toast.makeText(getApplicationContext(), "This is " +
                    adapterView.getItemAtPosition(i).toString(), Toast.LENGTH_LONG).show();

            try {
                //Your task here
            }catch (Exception e)
            {
                e.printStackTrace();
            }
        }

        @Override
        public void onNothingSelected(AdapterView<?> adapterView) {

        }
    });

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

        }
    });

}
