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

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_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();

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) {

        }
    });

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。
