【问题描述】：

我已经研究这个问题几个小时了，类似的错误没有解决办法。

我正在为不同活动中的多个 ListView 重用这个 XML 文件（我假设这与它有关），但我不明白它为什么会中断。 XML 文件表示 ListView 中的各个项目。

这是 XML：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:paddingTop="5dp" >

    <LinearLayout
        android:id="@+id/post"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="?attr/postBackground"
        android:orientation="horizontal" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical" >

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

                </LinearLayout>

        </LinearLayout>
    </LinearLayout>

</FrameLayout>

这里是Java（convertView = (FrameLayout) FrameLayout.inflate(mContext, R.layout.column_post, null);发生错误）：

提前致谢。

【问题讨论】：

你可以发布你的 stracktrace 吗？
好吧，第一件事：尝试删除行 android:background="?attr/postBackground" 并查看您是否有不同的日志（可能在另一行崩溃，或者可以工作）。
你确定你的两个活动都使用相同的主题？
哈哈，解决了。 +10000 分给你先生。
嗯，很高兴它有帮助。如果您愿意，我可以将我的评论作为您接受的答案，这样您就可以将您的 10000 分转换为 15。否则，只需提出解决方案并接受答案，以便对其他人有所帮助

【解决方案1】：

感谢@kiruwka，问题已解决！

问题是我需要确保在活动中使用相同的主题。

【讨论】：

【解决方案2】：

我会使用从上下文中获取的充气器，而不是 FrameLayout 中的静态方法，只是为了保持代码清晰。 FrameLayout 继承的 inflate() 方法只是调用 Context.getSystemService() 然后调用 inflate 的包装器。尝试将其更改为：

        convertView =
            (FrameLayout)inflater.inflate(mContext,
                                          R.layout.column_post,
                                          parent,
                                          false);

我怀疑您看到的崩溃是因为您为父级传递了 null 并且默认的 inflate() 变体将尝试将您正在创建的新子视图附加到父级（您不想这样做.)

【讨论】：

您的 XML 文件的名称是什么？我知道您说您将它重新用于多种用途，它只是重新命名的相同内容吗？这个 XML 文件是否位于树中 res/layout/column_post.xml 中？
是的，xml文件只是位于res/layout/column_post.xml中。只有当我在单独的活动中使用它时它才会崩溃。如果我在同一个活动中重用同一个 XML 文件，它工作正常。
刚刚解决了这个问题，@kiruwka 说要确保活动具有相同的主题。事实证明他们没有，并且成功了！

【解决方案3】：

我在很多项目中多次遇到这个问题，总是想我忘记的。

Android Studio --> Left menu--> Projects (Not Android)-->src --> res

drawable and drawable-v24 ，我的一些 xml files 但是位于 drawable-v24 下。把他们拖到drawable 问题就解决了
