Android蜂窝，得到碎片的实例？ [英] Android Honeycomb, get instance of Fragments?

问题描述

我有通过为标题中的XML文件加载两个片段一个preferenceActivity。

I have a PreferenceActivity that loads two Fragments via the xml file for the headers.

我似乎不能够设置一个标记或标识。或在头的XML片段的标记（即使用loadHeaderFromResource（加载）;

I don't seem to be able to set a tag or an ID. or a tag for the fragments in the header xml (that is loaded using loadHeaderFromResource();

由于我不实例化它自己，我没有身份证。或参考弄个。

Since I don't instantiate it myself I have no ID. or reference to get hold of it.

我该怎么办？

推荐答案

我不认为通过XML加载都给予了标签preference碎片，据我所知他们没有一个已知的ID，所以唯一的办法要做到这一点的可以的是（1）保持一个单独的列表＆LT;的WeakReference＆LT;片断＆gt;＆GT; 在 preferenceActivity ，并添加到该列表中的活动的 onAttachFragment （2）后来，看在该列表中，当你需要找到一个特定的片段

I don't think preference fragments loaded via XML are given a tag, and AFAIK they don't have a known ID, so the only way to do this may be to (1) maintain a separate List<WeakReference<Fragment>> in your PreferenceActivity and add to that list in the Activity's onAttachFragment and (2) later on, look in that list when you need to find a particular fragment.
