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

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();

Spinner spinner = (Spinner)findViewById(R.id.spinner);
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; ｝

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) {

        }
    });

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.
    }
}
