效果图：

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

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

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。
