android - 顺序动画 XML 中的错误

Question

我正在其中使用动画。我在使用顺序动画时遇到编译时错误。

错误是:

Multiple annotations found at this line:
    - error: No resource identifier found for attribute 'pivotX' in package 
     'android '
    - error: No resource identifier found for attribute 'fromXScale' in package 
     'android '
    - error: No resource identifier found for attribute 'toXScale' in package 
     'android '
    - error: No resource identifier found for attribute 'toYScale' in package 
     'android '
    - error: No resource identifier found for attribute 'duration' in package 
     'android '
    - error: No resource identifier found for attribute 'fromYScale' in package 
     'android '
    - error: No resource identifier found for attribute 'pivotY' in package 
     'android '

我的 xml 代码是:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android "
    android:fillAfter="true"
    android:interpolator="@android:anim/linear_interpolator" >

    <scale
        xmlns:android="http://schemas.android.com/apk/res/android "
        android:duration="1000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="3"
        android:toYScale="3" >
    </scale>


    <scale
        xmlns:android="http://schemas.android.com/apk/res/android "
        android:duration="1000"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="0.5"
        android:toYScale="0.5" >
    </scale>

</set>

谁能告诉我为什么是因为？

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" **<----- remove space**
    android:fillAfter="true"
    android:interpolator="@android:anim/linear_interpolator" >

    <scale
        xmlns:android="http://schemas.android.com/apk/res/android "
        android:duration="1000"
        android:fromXScale="1"
        android:fromYScale="1"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="3"
        android:toYScale="3" >
    </scale>


    <scale
        xmlns:android="http://schemas.android.com/apk/res/android "
        android:duration="1000"
        android:fromXScale="1.0"
        android:fromYScale="1.0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="0.5"
        android:toYScale="0.5" >
    </scale>
