Android的 - 动态改变布局中保存状态 [英] Android - Saving state of dynamically changed layout

问题描述

我有一个布局，用户可以添加按钮，并将其放置在那里他们想要的。
我想允许用户使其加载它们打开应用程序下一次挽救他们的布局。
有谁知道，如果我能救上SD卡的文件？我也可以使用某种layout.getXml（）方法，并把它放在我的应用程序使用的数据库。
在此先感谢

I have a layout where users can add buttons and place them where they want. I want to allow the user to save their layout so that it is loaded the next time they open the app. Does anyone know if I can save the file on the sdcard? Alternatively I could use some kind of layout.getXml() method and put it in the database my app uses. Thanks in advance

推荐答案

如果我是你，我会创建一个类都抱着这个布局和按钮的信息。而类的每个信息写与JSONWriter文件。当应用打开我只是用一个JSONObjects读取文件并重新创建阵列。

If I were you, I would create a class holding all the information about this layout and buttons. And write every information of the class to a file with JSONWriter. When the app has opened I just read the file and recreate the arrays using JSONObjects.
