个人preferences在一个ListView每个项目？ [英] Individual Preferences for each item in a ListView?

问题描述

我要创建我的第一个Android应用（或试图反正）和我有一个问题，我似乎无法找到答案。

I'm creating my first android app (or attempting to anyway) and i have a question i can't seem to find the answer to.

我想允许用户输入一组独立的preferences为在列表视图中的每个项目。我有preferenceScreen工作，但它保持了相同preferences为每个项目（即改变1项结果改变所有其他人也）。

I would like to allow users to enter a separate set of preferences for each item in a list view. I have the PreferenceScreen working, but it maintains the same preferences for every item (i.e. changing 1 item results in changes to all others as well).

要给出一个更详细的例子：
说我有车的列表：
*汽车1
* 2车
*等等...

To give a more detailed example: Say i have a list of cars: * Car 1 * Car 2 * Etc...

我想是不是有在全球范围内存储的条目能够点击汽车1，并获得了preferencesScreen指定制作只是那车，示范单位，颜色，整个应用程序。

I would like to be able to click on "Car 1" and get a PreferencesScreen to specify "Make", "Model", "Color" for just that car, instead of having those entries stored globally for the whole app.

这可能吗？

感谢您的帮助！

解决它！

有关的任​​何疑惑，解决的办法是，你必须调用

For any wondering, the solution is that you must call

的get preferenceManager（）。setShared preferenceName（值）独特的项目的值要修改preferences对（在我的情况，我用的ListView 位置）调用之前添加preferencesFromResource 。

getPreferenceManager().setSharedPreferenceName(value) with a value unique to the item you'd like to modify the preferences for (in my case, i used the ListView position) prior to calling addPreferencesFromResource.
