java - 如何使用pdfview在android中打开PDF

Question

我正在使用 android-pdfview-1.0.2.jar 我找到了它 here主项目的链接是here我正在尝试按如下方式加载 PDF

PDFView pdfView= (PDFView) findViewById(R.id.pdfView);
pdfView.fromAsset("sample.pdf")
.defaultPage(1)
.showMinimap(false)
.enableSwipe(true)
.onLoad(this)
.onPageChange(this)
.load();

我已经在我的布局中添加了 pdfView，如下所示

    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

    <com.joanzapata.pdfview.PDFView
        android:id="@+id/pdfView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>

执行时出现以下错误:
