克服很长的JSON字符串？

[英]Overcoming a Very Long JSON String?

原文 2018-10-01 16:14:51 8 1 java/ android/ json/ tcp

I am trying to build a weekly schedule, and I want to make an Android app to display it. 我正在尝试建立每周时间表，并且想制作一个Android应用程序来显示它。

I have to send a Week object that contains a list of days, which contains a list of hours, which contains a list of events. 我必须发送一个Week对象，其中包含天列表，其中包含小时列表，其中包含事件列表。

Every event has multiple variables. 每个事件都有多个变量。

The data comes from a local database I built on my PC, and on the app I set a GUI friendly query which returns the planned week in a JSON format. 数据来自我在PC上构建的本地数据库，并且在应用程序上设置了GUI友好查询，该查询以JSON格式返回计划的星期。

Now that JSON has become 2000 lines long on the best case, and around 5000 lines worst case. 现在，在最好的情况下，JSON已变成2000行长，而在最坏的情况下则变为5000行左右。

Any suggestions on how I can handle this? 关于如何处理此问题的任何建议？

Another problem is that the JSON comes back in packets, so I cannot parse parts on it until I receive it fully, and Java cannot handle such long strings. 另一个问题是JSON以数据包的形式返回，因此在完全接收到它之前，我无法解析其部分，而Java无法处理如此长的字符串。

I would suggest you to use Firebase as your database. 我建议您使用Firebase作为数据库。 Firebase is a cloud database which can be accessed by web and android app also. Firebase是一个云数据库，也可以通过Web和android应用程序进行访问。 The data is kept synced at all times so you do not need to fire a different query in your app. 数据始终保持同步，因此您无需在应用中触发其他查询。

Just store the data in Firebase from your pc and access it via android app and display it. 只需将数据从您的PC存储在Firebase中，然后通过android应用访问并显示它。

Hope this helps. 希望这可以帮助。
