我正在尝试向LinearLayout的背景添加渐变,它给了我一个ClassNotFoundException。

这是布局: RES /抽拉/ blue_gradient.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <gradient 
        android:startColor="#003399" 
        android:endColor="#002288"
        android:angle="270"
     />
</shape>

RES /布局/ main.xml中

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/blue_gradient"
    android:orientation="horizontal" 
    android:layout_gravity="right" >

以下是例外:
