Android動畫-不允許使用字符串類型

Question

我為我的應用創建了一個動畫資源，但是在構建它時聲稱所有屬性string types are not allowed “ string types are not allowed ”。 我正在以20的sdk進行編譯，最低為14，目標為20。

score_animation.xml：

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

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

傻我！ 原來，它不喜歡附加的f因此刪除它們（從1.0f到1.0等）解決了問題。
