java - 在 onCreateView 中膨胀类时出错...

Question

我正试图摆脱一个麻烦的异常。

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.galleryphoto_fragment, null);
...

This line leads to Binary XML file line #13: Error inflating class pl.XXX.app.utils.ImageViewZoom

这个 XML 文件看起来像这样:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ProgressBar
        android:id="@+id/spinner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="gone" />

    <pl.XXX.app.utils.ImageViewZoom <!-- line #13 -->
        android:id="@+id/mainPhoto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="matrix" />

</FrameLayout>

我已经为您标记了第 13 行。

我尝试了什么？好吧，最初我认为这是 ImageViewZoom 错误没有正确注册，但是当从另一段代码调用时它正在工作。有人能给我指出正确的方向吗？

更新 这是堆栈:

Answer 1

Caused by: java.lang.NoClassDefFoundError: it.sephiroth.android.library.easing.Cubic
  at it.sephiroth.android.library.imagezoom.ImageViewTouchBase.<init>(ImageViewTouchBase.java:72)
  at it.sephiroth.android.library.imagezoom.ImageViewTouch.<init>(ImageViewTouch.java:42)
  at pl.XXX.app.utils.ImageViewZoom.<init>(ImageViewZoom.java:21)
  at pl.XXX.app.utils.ImageViewZoom.<init>(ImageViewZoom.java:17)

您的 ImageViewZoom 构造函数最终调用了 ImageViewTouchBase 构造函数，其中 it.sephiroth.android.library.easing.Cubic 无法找到。确保代码包含在您的项目中。
