Android 6.0 棉花糖 : Weird error with fragment animation

Question

我在应用商店中的一个应用在 Android 5.0 上运行得非常好，但自从今天我将设备升级到 6.0 后，我遇到了奇怪的错误。我将范围缩小到 fragment 过渡动画。

ftrans.setCustomAnimations(inAnim, outAnim, inAnim, outAnim);

没有这条线，我的应用程序在 6.0 上也能正常工作，但我得到了这个错误:

我使用的“in”动画如下所示:

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

<alpha
    android:fromAlpha="0" android:toAlpha="1"
    android:startOffset="@integer/fadein_offset"
    android:duration="@integer/fadein_duration"/>

<scale
    android:fromXScale="0%" android:toXScale="100%" android:fromYScale="0%" android:toYScale="100%"
    android:pivotX="50%"
    android:pivotY="50%"
    android:startOffset="@integer/fadein_offset"
    android:duration="@integer/fadein_duration"/>

“out”动画看起来相同，只是颠倒了。

所以我的问题是，这个错误是什么意思，你如何在棉花糖中进行 fragment 转换？

编辑:我的 addFragment 方法，我使用 setCustomAnimations()。我添加了 SDK 检查，因为我使用了在较低 Android 版本上存在问题的缩放动画。但是请注意，此代码适用于 Android <6，动画运行良好，并且运行了 3 年。

private void addFragment(Fragment f, boolean addToBackstack, String tag) {
    FragmentManager fman = getSupportFragmentManager();
    FragmentTransaction ftrans = fman.beginTransaction();

//        if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.HONEYCOMB) {
//             ftrans.setCustomAnimations(inAnim, outAnim, inAnim, outAnim);
//        }

    if(addToBackstack) ftrans.addToBackStack(tag);
    ftrans.replace(R.id.content, f, tag);
    ftrans.commit();
}

在 fragment 1 中按下按钮时，我通过接口(interface)委托(delegate)给 Activity 并在那里调用

@Override
public void showFacts(DBCategory category) {
    addFragment(FragFacts.Instance(category.id(), category.name()), true, FragFacts.TAG);
}

编辑 2: 我发现它一般不是动画，它只是我的过渡的比例动画部分导致它。我把它拿出来了，现在可以了。

这是 Marshmallow 在我们进行缩放动画时出现的错误。现在我们通过设置 view.setLayerType(View.LAYER_TYPE_SOFTWARE) see documentation 找到了解决方法
