遇到的几个问题:

1.在gradle的时候没有报错,但是调试就会闪退

(1)如果是打开软件就闪退,可能是初始布局有问题

(2)如果是点击某个按钮有问题,可能是跟按钮触发相应的语句有问题

2.与数据库有关的问题

(1)数据库为null,这个在gradle也不会报错,而且as的编辑器也没有报错

通过仔细检查,发现bean里写错了

安卓学习记录(五)——体温表APP.2

可以发现虽然没有报错,但是‘sex’是灰色的,也就是没有用上,以后会注意这种问题,不一定标红线才是报错

(2)使用正常,但是name始终显示的是date

这个花了好久才发现在哪出了问题

安卓学习记录(五)——体温表APP.2

name、date、sex这三个位置反了

因为前一个问题写了,sex获取有问题,这导致了sex为null。位置写反了,这导致了name获取了date,而date是自动获取不是手动输入的,最终导致了姓名一栏始终显示的是日期,而日期却还是正确日期

这个地方几个错误叠加,反而没看出来错误的本质,我之前一直以为是name一栏写成了date,检查后发现setText()写的并没有问题,

花了好久才发现原来是数据库这边位置反了。

有几个文件上传不进去,不知道是不是我的方法有问题
