EdgeEffect上的UnsupportedOperationException

Question

初始化从xml中膨胀的ViewPager时，我的应用程序失败。以下是从Android src EdgeCompat.java

崩溃的行

final TypedArray a = context.obtainStyledAttributes(com.android.internal.R.styleable.EdgeEffect);
final int themeColor = a.getColor(com.android.internal.R.styleable.EdgeEffect_colorEdgeEffect, 0xff666666);

这由ViewPager.initViewPager()调用，我在堆栈跟踪中看到的所有内容都是在给布局膨胀时出错。

我附上了

<merge xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/transparent"
    android:clickable="true" >

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/transparent"
        android:overScrollMode="never" />

    <LinearLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:background="@android:color/black" />

</merge>
