我试图夸大这个观点

<LinearLayout android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="16dp">

    <TextView android:id="@android:id/text1"
        style="?android:textAppearanceLarge"
        android:textStyle="bold"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="16dp" />


    <pdftron.PDF.PDFViewCtrl
        android:id="@+id/pdfviewctrl"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scrollbars = "vertical|horizontal" />

</LinearLayout>

在我的片段 onCreateView 函数中是这样的。

 View rootView =   inflater
            .inflate(R.layout.fragment_screen_slide_page, container, false);

但它返回一个错误“错误膨胀类pdftron.PDF.PDFViewCtrl”。任何人都可以指出原因（我成功地在活动中设置了这个布局，并且能够访问PDFViewCtrl并向它添加一个pdf文档。）在决定购买许可证之前，我只是想根据我的要求自定义 PDFTron。

I was able to reproduce a similar error when I didn't initialize PDFNet before calling the inflater. Try calling PDFNet.initialize() before calling setContentView() or the inflater.
