从嵌套的Andr​​oid preferenceScreen返回previous preferenceScreen

问题描述

我编程方式创建一组嵌套 preferenceScreen 取值。当用户潜入这些屏幕之一，水龙头东西在那里，我要回去了previous preferenceScreen （即父）。

I am programmatically creating a nested set of PreferenceScreens. When the user dives into one of these screens, and taps something in there, I want to go back to the previous PreferenceScreen, (i.e. the "parent").

我找不到这方面的消息，并要求完成（）没有做的工作，但距离，而返回的所有 preferenceScreen 的S只是一个替代。

I couldn't find any information on this, and calling finish() doesn't do the job but rather returns from ALL the PreferenceScreens instead of just one.

推荐答案

我正好符合这个问题，只是找到了解决办法。您可以覆盖在preferenceActivity在preferenceTreeClick的方法。调用参数preferenceScreen的getDialog方法，然后调用该对话框的解雇方式。就这样，快乐！

I just meet the problem and just found the solution.You can override the method onPreferenceTreeClick in PreferenceActivity.call the param preferenceScreen's getDialog method, then call the dialog's dismiss method.just like this, joy!
