SharedPreferences.edit介绍

[英]Create a new Editor for these preferences, through which you can make modifications to the data in the preferences and atomically commit those changes back to the SharedPreferences object.

Note that you must call Editor#commit to have any changes you perform in the Editor actually show up in the SharedPreferences.
[中]为这些首选项创建一个新的编辑器，通过它可以修改首选项中的数据，并自动将这些更改提交回SharedReferences对象。
请注意，您必须调用编辑器#提交，以使您在编辑器中执行的任何更改实际显示在SharedReferences中。
