Android的棒棒糖动画毛刺 [英] android lollipop animation glitch

问题描述

我有一个奇怪的行为与默认布局动画运行Android 5（棒棒堂）设备。我使用与被替换在运行时使用默认的片段管理多个片段的活动。当更换旧的片段，我想用动画的流畅的UI流。在pre-棒棒糖设备的动画作品像预期，但在设备上运行的是最新的操作系统，碎片毛刺的动画：

I have a strange behaviour with the default layout animation in devices running Android 5 (Lollipop). I am using an activity with multiple Fragments which are replaced at runtime using the default fragment manager. When replacing the old fragment, i want to use an animation for a smooth ui flow. On pre-lollipop devices the animation works like expected, but on devices running the latest os, the animation between fragment glitches:

我尝试使用默认的动画XML标签

I tried using the default animation xml tag

android:animateLayoutChanges="true"

由于它不工作，我把它用这个code没有影响

Because it does not work, i changed it using this code with no effect

mTransaction = mManager.beginTransaction();
        mTransaction.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);
        mTransaction.remove(mFragment);
        mTransaction.add(R.id.container, mFragment, "fragment");
        mTransaction.commit();

我已经在不同的设备和Android模拟器测试code。但奇怪的是，它的工作原理是预期上运行pre-棒棒糖设备和 Android模拟器运行最新的操作系统（5.0.1）。 不过，这并不对设备一样工作的Nexus 4和Nexus 5运行Android 5.0

I have tested the code on different devices and in the android emulator. The strange thing is, that it works like expected on devices running pre-lollipop and in the android emulator running the latest OS (5.0.1). But it does not work on devices like Nexus 4 and Nexus 5 running Android 5.0

有什么建议？任何帮助吗？

Any suggestions? Any Help?

It seems to be a bug depending on the used device. I have tested the code on different devices (Samsung Galaxy S4, HTC (One mini2, One M8, Desire S), Nexus 4&5), and it only appears on google nexus devices.
