Answer 1

您必须使用 setOnItemSelectedListener 而不是 getOnItemSelectedListener。像下面这样。

height_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

      @Override
      public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {

    }

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

    }
});
