Spinner.setOnItemClickListener不起作用 [英] Spinner.setOnItemClickListener not working

问题描述

这是我的代码：

transactionTypeSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(MainActivity.this, "Something changed", LENGTH_SHORT).show();
        }
    });

但很遗憾OnItemClickListener方法不起作用，并显示此消息：setOnItemClickListener cannot be used with a spinner.

我如何解决该问题？

谢谢！

推荐答案

不应调用OnItemClickListener获取微调函数。微调控件不支持项单击事件。

 transactionTypeSpinner.setOnItemSelectedListener(new OnItemSelectedListener() 
    {
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) 
        {
            Toast.makeText(MainActivity.this, "Something changed", LENGTH_SHORT).show();
        } // to close the onItemSelected
        public void onNothingSelected(AdapterView<?> parent) 
        {

        }           
    });
