我正在android中创建概念,它将向此应用程序的用户(其中一名员工)显示员工的工作时间。首先,我将两个日期发送到php
文件中,以检索两个日期之间的数据,即工作时间的开始和结束时间。
这个概念在php
文件中运行良好,我能够检索数据。
但是,当我尝试显示时,我面临三个问题。
第一次约会-2018年9月12日
最后日期-14-12-18
php
文件为此日期发送null
,但下一个日期结束日期具有值(2018年10月12日至14-12-18(最后日期))。使用计数概念,我正在显示员工的工作时间。我发送计数0以显示第一个日期,但它是null
,因此它不会显示任何内容,因为我尝试在if else
循环中使用for
部分,当{ {1}}部分被执行,应用被压碎。
当单击下一个按钮时,它应删除9-12-2018的数据,并显示10-12-2018的数据,但显示在同一页面上。
我用过
else
删除以前的数据,但是当我在stk.removeView(tbrow);
stk.removeView(tbrow0);
函数的开头使用此数据时,每次调用该函数时都会删除前一行,并且仅显示一个员工的工作时间。
这是我的活动文件:
init
无需单击下一步按钮即可输出:
在单击下一步按钮时:
