微调器无法使用“getOnItemSelectedListener”方法。请建议编辑并解决我的问题 [错误如上所示]

您必须使用

setOnItemSelectedListener

而不是

getOnItemSelectedListener

。像下面这样

        ArrayAdapter<CharSequence> adapter_height = ArrayAdapter.createFromResource(this,R.array.Height,android.R.layout.simple_spinner_item);
        adapter_height.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        height_spinner.setAdapter(adapter_height);

    height_spinner.getOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        }

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

        }
    });

height\u微调器.setOnItemSelectedListener（新的AdapterView.OnItemSelectedListener（）{
@凌驾
已选择公共位置（AdapterView AdapterView、视图视图、整型位置、长id）{
}
@凌驾
未选择公共无效（AdapterView AdapterView）{
}
});

height_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

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

    }

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

    }
});
