android软件简约记账app开发day05-记账页面条目代码优化和bug解决

今天还是因为该bug又极大的耽误了项目进程,该开发文档都要没有时间来写了。

先说bug吧,在昨天已经实现了页面图标的展示,并且可以左右滑动来切换时支出还时收入页面,可就是在页面上部不显示支出和收入,这让我百思不得其解,翻看项目目录也不知道时那里的问题,我首先试了试Debug来看一下,我打了几个断点,可以当我点击那个晓聪子按钮时,他还让我下载什么东西,我心想我就调试一下,你就每一步就给我走不就完了,还要下载什么东西,真是无语,算了,还是下吧,可我这一点击download,这要下载的东西可多啊,愣是下了得有5分钟,当我下载完后,本以为点击debug按钮后该bug就能简简单单的解决时,知识砂纸擦屁股给我露了一手啊,这来来回回跳转的类得有百十来个,我点啊点,看呀看,是又点不玩,又看不到,来回挑战java类,也还不加载页面,我心想写个日志看看能打印出什么来不,可他就是出不来,什么也输出不了。

其次我就放弃了调试,选择从头梳理一下逻辑,既然能加载,说明记一笔可以点击,并且页面可以跳转,条目可以显示,说明从数据库角度来说没有问题,我相当于又从头看了一下所有昨天写的代码,终于我点进了写的适配器类RecordPagerAdapter我发现在我定义的String[] titles={"支出","收入"};竟然是灰的,这属实让我心头一紧,我立马就发现了

public CharSequence getPageTitle(int position) {
    return titles[position];
}

该类没改return,当然这是改过之后的,这、啊这、啊这这这、哎,我就无语,怎么能有我这么菜的人。

现在看着写起来也就四五百字,这可是四五个小时才发现的。。。。。。

接下来,让我来优化一下代码,稍微、简单的优化一下,把outcomefragment和incomefragment两个类的相同部分抽取一下,写成baserecordfragment类,在用两个类继承一下。

最后写了一个账单类来存储用户打算存的账单信息。
