Android 无法获得使用微调器的意图

我试图用意图替换下面代码中的祝酒词，但无论我尝试了多少种方法，它们都无法工作。问题只不过是加载应用程序时模拟器上出现了一个白色屏幕。 任何协助都将不胜感激

    spinner.setOnItemSelectedListener(new OnItemSelectedListener()
    {

        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TODO Auto-generated method stub
            switch (arg2) {
            case 0:                 
                Toast.makeText(UsefulToolsActivity.this, "Tool, Countdown. Selected.", Toast.LENGTH_SHORT).show();
                break;

            case 1:                 
                Toast.makeText(UsefulToolsActivity.this, "Tool, Countdown. Selected.", Toast.LENGTH_SHORT).show();                       
                break;

            default :                       
                break;
            }
        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
    });
}

如果ne-Inent（）的两个参数相等，则getIntent（）将适用于spinner。。否则就不会了。

经过大量实验后找到了答案，结果是我忘了实现OnItemSelectedListener。

有祝酒词吗？您是否检查了是否调用了onItemSelected？以及如何使用意图？显示您的代码。提供更多的代码和生成的错误（如果有）

    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
            // TODO Auto-generated method stub
            switch (arg2) {
            case 0:                 
                Intent intent1 = new Intent(UsefulToolsActivity.this, CountdownActivity.class);
                startActivity(intent1);                        
                break;

            case 1:                 
                Intent intent2 = new Intent(UsefulToolsActivity.this, CountdownActivity.class);
                startActivity(intent2);                       
                break;

            default :                       
                break;
            }
        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
        }
