你需要修复你的导入。
你可能导入了错误的类，现在 eclipse 认为你想要别的东西。

您应该使用以下侦听器：

m_listView.setOnItemClickListener(new OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> p_arg0, View p_arg1, int p_arg2, long p_arg3)
        {
            // TODO Auto-generated method stub
        }
    });
