错误膨胀类片段 [英] Error inflating class fragment

问题描述

我收到错误

Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binary XML file line #11: Error inflating class fragment

当我通过纵向和横向模式切换时.我正在使用碎片.我的 xml 是:

when I switch via the portrait and the landscape mode. I'm using fragments. My xml is:

 <LinearLayout android:id="@+id/mainLayout"
               android:orientation="horizontal"
               android:layout_width="fill_parent"
               android:layout_height="wrap_content" >

    <ListView android:id="@+id/android:list"
              android:layout_height="wrap_content"
              android:layout_width="fill_parent"/> 

    <fragment android:id="@+id/fragmentDetails"
              android:layout_height="fill_parent"
              android:layout_width="fill_parent"
              class="de.androidbuch.activiti.task.TaskDetailsFragment"/> 
</LinearLayout>

如果我通过横向和纵向模式切换，一切正常.但是当我点击我的片段(我可以看到我的片段)然后切换到其他模式时，我得到了错误.知道我该如何解决吗?在这里找到了一些答案，但这些都没有帮助我...

If I switch via landscape and portrait mode everything works fine. But when I click on my fragment (and I can see my fragment) and then switch to the other mode I get the error. Any idea how I can solve it? Found some answers here but none of these helped me out...

推荐答案

正如 hdemirchian 所说，确保使用:

As hdemirchian said, make sure to use:

import android.support.v4.app.Fragment;

还要确保使用片段的 Activity 扩展 FragmentActivity 而不是常规的 Activity，

And also make sure that the Activity that is using the fragment(s) extends FragmentActivity instead of the regular Activity,

import android.support.v4.app.FragmentActivity;

获取FragmentActivity 类.
