1. 运行效果
实际的效果比图片看起来要更加丝滑流畅，已验证过大部分的主流机型，即使机子本身比较卡顿，跑起来后也是非常丝滑流畅的，并已运用到实际的项目当中

2. 完整代码
代码很简单，两个属性动画，一个处理旋转，一个处理旋转时的缩放，硬件加速能有效提升动画体验

3. 布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/root_view"
        android:layout_width="240dp"
        android:layout_height="480dp">

        <TextView
            android:id="@+id/root_view_2"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#6200EE"
            android:gravity="center"
            android:text="2"
            android:textColor="#FFFFFF"
            android:textSize="20sp"
            android:visibility="invisible" />

        <TextView
            android:id="@+id/root_view_1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#03DAC5"
            android:gravity="center"
            android:text="1"
            android:textColor="#FFFFFF"
            android:textSize="20sp"
            android:visibility="visible" />

    </FrameLayout>

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="onClickRotate"
        android:text="翻转" />

</LinearLayout>

4. 使用

AnimationHelper.start3DRotateAnimator(rootView, rootView2, rootView1);
