Android 将数据排序到数组中 - ArrayAdapter JSON Listview

Question

我有一个MySQL table 叫做foods，其中包含饮食信息。我目前运行 php 脚本调用以下 sql 命令 Select * 来自 Food where dietid = 1 which returns 下面的图片。

day 栏是节食的日子，所以第 1 天、第 2 天等。时间指的是一天中的某个时间点，所以时间 1 是早餐时间 2 是点心时间 3 是午餐时间 4 是下午点心时间 5 是晚餐。

我想在列表视图中按以下方式显示数据 diet.Description 的每一天都是由数量度量和项目组成

目前我在 log-cat 中有以下输出。

使用 Jims approact，我已经能够按照我需要的格式按日期和时间对这些数据进行分组，但是我现在面临着我之前遇到的问题，列表被夸大了，它将信息放在每个当我需要每 1 天排成 1 行时排。

问题是现在它会像这样膨胀视图，从而创建一个视图并将其放入每个项目。

更新了阵列适配器#

我想每天将这些数据分组到数组中，所以它是第 1 天 - 早餐 - 项目，零食 - 项目等......这样我就可以将它们全部放在一个列表中供用户使用查看。

我所有的数据都存储在 2 模型中类。下面是我的适配器型号类.

谢谢 :) 到达那里..

您需要为您的对象添加自定义 Comparator，然后您可以使用 Arrays.sort 方法进行任何您喜欢的排序。

这里有一份关于如何制作和使用Comparator的参考：

http://examples.javacodegeeks.com/core-java/util/comparator/java-comparator-example/

编辑：

除了排序之外，您可能还应该对现有数据集使用 Adapter。换句话说，你的 Adapter 中的这些行不应该存在：

        Collections.sort(daylist, new DayComparator());
        daylist.add(dayfoodmodel);

首先，您正在排序 - 然后添加数据。您所有的数据都应该在数组中，然后对其进行排序。

其次，您应该将所有数据传递到 Adapter，这样排序应该发生在之前您在 Adapter 中执行 getView
