在你的 WhateverAdapter 添加这些方法：

public void setOnSpinnerItemSelectedListener(OnItemSelectedListener listener){
    this.mSpinnerItemSelectedListener = listener;
}

在你的 getView（）方法：

public View getView(int position, View convertView, ViewGroup parent){
     //...

     viewHolder.spinner.setOnItemSelectedListener(mSpinnerItemClickListener);
     //.....
     return convertView;
}

然后在你的活动或其它地方：

MyAdapter adapter = new MyAdapter(Context....);
adapter.setOnSpinnerItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // your code here
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // your code here
    }

});
myListView.setAdapter(adapter)
