android - 膨胀 android.support.v4.ViewPager

Question

尽管我已经在 stackoverflow 中尝试了当前的解决方案 Here和 Here ，我仍然无法解决膨胀的 ViewPager 错误。我正在使用 UniversalImageLoader 库，我想我已经以正确的方式引用了最新版本的 android.support.v4 库。在这里你可以看到我的代码和设置:

图像寻呼机类

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.ac_image_pager); //Here it returns the error below

    ...

ac_image_pager 布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
     android:background="#000000"
    android:orientation="vertical" >

    <android.support.v4.view.ViewPager  <!--Error shows this line-->
        android:id="@+id/pager"
       android:layout_above="@+id/ll"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />


</RelativeLayout>

Answer 1

你的异常(exception)是:

android.view.InflateException: Binary XML file line #9: Error inflating class com.example.imageapp.ScaleImageView`

您粘贴的布局文件没有 ScaleImageView。当您使用 ViewPager 触发您的问题时，您的实际问题出在页面中，ViewPager 正在创建，这可能涉及不同的布局文件。

请确保您有一个完全限定名称为 com.example.imageapp.ScaleImageView 的类。
