对于基于CursorAdapter的旋流器:

获得所选项目id: spinner.getSelectedItemId() 从数据库中获取项目名称，例如: getCountryName(int pId){ 游标cur = mDb。查询(表、新String [] {COL_NAME} COL_ID + = ?”,新String [] {pId + " "},空,空,空); 字符串ret = null; 如果(cur.moveToFirst ()) { ret = cur.getString(0); ｝ cur.close (); 返回受潮湿腐烂; ｝

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

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_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

        }
    });

}

一行版本:

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

更新: 如果使用SDK 26(或更新版本)编译项目，则可以删除强制转换。

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