将布局与背景图像和图像按钮放在一起时的运行时错误？

Question

我使用android-8（2.2），当我尝试将背景设置为linearlayout并放置一个图像按钮时，它会产生运行时错误。有谁知道如何在这个Android版本中修复它？

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:id="@+id/signUpLayout"
              android:background="@drawable/loginbackground">
    <ImageButton android:layout_width="fill_parent"
                         android:layout_height="fill_parent"
                         android:id="@+id/signUpButton"
                         android:src="@drawable/facebooksignupbutton"
                         android:scaleType="centerCrop"
                         android:background="@android:color/transparent"
                         android:clickable="true"/>

</LinearLayout>

以下是日志：
