Android的数据排序为数组 - ArrayAdapter JSON列表视图 [英] Android Sorting data into arrays - ArrayAdapter JSON Listview
问题描述
我有一个MySQL表称为包含饮食信息食品。我目前运行的PHP脚本调用从食品以下SQL命令选择*其中dietid = 1返回下面的图片。
列日是减肥的日子，所以1天，2天等的时间是指白天的一个点左右的时间1是早餐的时候2是点心时间3是午饭时间4日下午点心和时间5晚餐。
我想为diet.Description每天一个ListView显示在以下方式中的数据是做出来的数量测量和项目
的 
我在登录猫此刻以下输出。
更新 - 编辑新建的logcat
使用吉姆的approact我一直能集团这一数据按日期和时间在但是，我需要现在我面临着我面临问题之前的格式，名单被充气，它把信息的每一行时我需要这一切是在1行的每一天。
问题是，现在它膨胀这样它创建一个视图，并把它在每个项目的意见。
已更新一个ArrayAdapter＃
我想组中的每一天数组这一数据，所以这将是第1天 - 早餐 - 项目，小吃 - 项目等等，这样我可以把它在一个列表供用户查看。
我所有的数据都存储在2模型类。下面是我的适配器与模型类。
谢谢:)到达那里。

您需要一个自定义的比较添加到您的对象，那么你可以使用 Arrays.sort 办法做任何你喜欢的一种排序。
下面是关于如何制造和使用一个参考比较：
的http://examples.java$c$cgeeks.com/core-java/util/comparator/java-comparator-example/
编辑：
除了排序，你应该使用适配器对现有的数据集。换句话说，这些线在你的适配器应该不存在：
Collections.sort（daylist，新DayComparator（））;
daylist.add（dayfoodmodel）;
首先，要排序 - ，然后添加数据。所有的数据应该是数组中，然后排序。
其次，你应该通过所有的数据到适配器这样的排序应该发生的之前您 getView 在适配器
I have a MySQL table called foods which contain diet information. I am currently running the php script which calls the following sql command Select * from Food where dietid = 1 which returns the image below.
The column day is the day of the diet so day 1, day 2 etc.. the time refers to a point during the day so time 1 is breakfast time 2 is snack time 3 is lunch time 4 is afternoon snack and time 5 is dinner.
I would like to display the data in the following way in a listview for each day of the diet.Description is the made out of qty measure and item
I have the following output in the log-cat at the moment.
UPDATE - EDIT NEW LOGCAT
Using Jims approact i have been able to group this data by day and time in the format that i require however i am now facing the problem which i was facing before, the list gets inflated and it puts the information in each row when i need it all to be in 1 row per 1 day.
The problem is that now it inflates the views like this which creates one view and puts it in for each item.
UPDATED THE ARRAYADAPTER#
I would like to group this data in arrays for each day, so it would be day 1 - breakfast - item, snack - item etc... so that i can put it all in one list for the user to view.
All my data is stored in 2 model classes. Below is my adapter with the model classes.
Thanks :) getting there..

You need to add a custom Comparator to your object, then you can use Arrays.sort method to do sorting of whatever kind you like.
Here is one reference on how to make and use a Comparator:
http://examples.javacodegeeks.com/core-java/util/comparator/java-comparator-example/
EDIT:
Besides the sorting, you should probably use an Adapter against an existing data set. In other words, these lines in your Adapter should not exist:
Collections.sort(daylist, new DayComparator());
daylist.add(dayfoodmodel);
First, you are sorting - then adding data. All your data should be in the array, and then sort it.
Second, you should pass all the data into the Adapter so the sort should occur before you do getView in the Adapter
