安卓&碎片

简而言之：我将向您展示我的问题的抽象版本，所以我有： - 1 个 Activity，1 个 main.xml，其中 1 个 FrameLayout 作为容器（ID = main_container） - 片段A，B（A有点复杂）

我可以在main_container中插入任何片段A或B，没有任何问题。我还可以做一些片段替换B，A，B，A（当我进行最后一次交换时它失败了！）或A，B，A（在最后一个交换时再次失败）

为了让你了解我的android技能，我总是这样做：

 FragmentX newX = FragmentX.newInstance(..); 
 FragmentTransaction ft ..
 ft.replace(R.id.main_container, newX);
 //ft.addToBackStack(null);
 ft.commit();

所以我收到的错误：

"E/AndroidRuntime(2559): android.view.InflateException: Binary XML file line #7: Error inflating class fragment
...
E/AndroidRuntime(2559):     at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:664)"

这种方法有问题吗？您是否需要回收片段，因为如您所见，我总是使用 newInstance() 静态方法？或者您认为问题出在其他地方？

====更新==== 原来我的情况是这样的：片段A（复杂的:)）膨胀了一个fragment_A.xml，它有2个片段标签，为此我确实定义了2个片段类。

无论如何，我做了修改，从fragment_A.xml中删除2个片段标签并使用2包含标签..并且只使用一个大片段类:(。

现在它工作得很好，但在我看来，以前的形式应该已经工作了。

To cut is short: I will present you a abstract version of my problem, so I have:
- 1 Activity, 1 main.xml with 1 FrameLayout as a container (ID = main_container)
- Fragment A, B (A is a bit more complex)

I can insert any fragment A or B in main_container, without any problems. I also can do some fragment replacing B,A,B,A (when I do the last swap it fails!) or A,B,A (again it fails at the last one)

To give you a idea of my android skills, I always do:

 FragmentX newX = FragmentX.newInstance(..); 
 FragmentTransaction ft ..
 ft.replace(R.id.main_container, newX);
 //ft.addToBackStack(null);
 ft.commit();

So the error I receive:

"E/AndroidRuntime(2559): android.view.InflateException: Binary XML file line #7: Error inflating class fragment
...
E/AndroidRuntime(2559):     at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:664)"

Is there something wrong with this aproach? Do you need to recycle fragments, because as you see I always use the newInstance() static method? Or do you think the problem is elsewhere?

==== UPDATE ====
It turns out that my situation was like this:
fragment A (the complex one :)) inflated a fragment_A.xml which had inside 2 fragment tags, for which I did had 2 Fragment classes defined..

Anyways I made the modication of removing the 2 fragment tags from fragment_A.xml and using 2 include tags..and using just one big fragment class :(.

And now it works just fine, but in my mind previous form shoud have worked to.
