不允许使用java Android动画字符串类型

Question

我为我的应用程序创建了一个动画资源，但是在构建它时，它声称所有属性都是“string types are not allowed”。我在sdk 20上编译，最小值为14，目标值为20

为动画配乐。xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    安卓:interpolator="@安卓:anim/accelerate_decelerate_interpolator"
    安卓:shareInterpolator="true"
    安卓:ordering="sequentially">
    <set>
        <alpha
            安卓:duration="300"
            安卓:fromAlpha="0f"
            安卓:toAlpha="1f" />
        <scale
            安卓:duration="300"
            安卓:fromXScale="0.4f"
            安卓:fromYScale="0.4f"
            安卓:pivotX="50%"
            安卓:pivotY="50%"
            安卓:toXScale="1.0f"
            安卓:toYScale="1.0f" />

    </set>
    <alpha
        安卓:duration="300"
        安卓:fromAlpha="1f"
        安卓:startOffset="600"
        安卓:toAlpha="0f" />
</set>

完全错误：

Error:(9, 32) String types not allowed (at 'fromAlpha' with value '0f').
Error:(10, 30) String types not allowed (at 'toAlpha' with value '1f').
Error:(13, 33) String types not allowed (at 'fromXScale' with value '0.4f').
Error:(14, 33) String types not allowed (at 'fromYScale' with value '0.4f').
Error:(17, 31) String types not allowed (at 'toXScale' with value '1.0f').
Error:(18, 31) String types not allowed (at 'toYScale' with value '1.0f').
Error:(23, 28) String types not allowed (at 'fromAlpha' with value '1f').
Error:(25, 26) String types not allowed (at 'toAlpha' with value '0f').

我真傻发现它不喜欢附加的f，所以将它们删除（1.0f到1.0等）解决了问题
