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.
