android;在AdapterViewFlipper上设置动画的输入/输出：未知的动画师名称翻译 [英] android; setting in/out animations on AdapterViewFlipper: Unknown animator name translate

问题描述

我有一些非常简单的动画，可以很好地与ViewFlipper一起使用，但是如果尝试在AdapterViewFlipper上输入/输出上设置它们，则会收到运行时错误未知的动画师名称翻译。在查看每个方法的各个方法时，ViewFlipper期望使用ViewAnimation，而AdapterViewFlipper期望使用AdapterViewAnimation。否则，其他API都是相同的，并且两者的构建都没有错误。这是其中一个动画的xml：

 <？xml version = 1.0 encoding = utf-8？ > 
< set xmlns：android = http://schemas.android.com/apk/res/android 
 android：shareInterpolator = false> 
 
<翻译
 android：fromXDelta = 0％ android：toXDelta =-100％ 
 android：fromYDelta = 0％ android：toYDelta = 0 ％ 
 android：duration = 800 /> 
< / set> 
  

我将它放在脚蹼上，如：

  vf.setOutAnimation（this，R.anim.out_to_left）; 
  

我猜这可能意味着我不能使用翻译，输入，但是我将如何使用完成相同的动画？ me脚...

看来，ViewFlipperAdapter需要一个objectAnimator，而不是set。 / p>

在动画器文件夹中声明的示例left_in.xml

 < objectAnimator xmlns：android = http://schemas.android.com/apk/res/android 
 android：interpolator = @ android：anim / accelerate_decelerate_interpolator 
 android：propertyName = x 
 android：valueType = floatType 
 android：valueFrom =-1500 
 android：valueTo = 0 
 android：duration = 600 /> 
  

I have some very simple animations that work perfectly with a ViewFlipper, but if I try setting them on an AdapterViewFlipper in/out, I get a runtime error "Unknown animator name translate". In looking at the respective methods on each, it looks like ViewFlipper expects a ViewAnimation, and AdapterViewFlipper expects an AdapterViewAnimation. The api's are otherwise the same, and both build without error. Here's the xml for one of the animations:

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

    <translate
    android:fromXDelta="0%" android:toXDelta="-100%"
    android:fromYDelta="0%" android:toYDelta="0%"
    android:duration="800"/>
</set>

and I set it on the flipper like:

vf.setOutAnimation(this, R.anim.out_to_left);

I can guess this might mean that I can't use translate, type, but then how would I accomplish the same animation? Lame...

解决方案

Found the answer here: https://stackoverflow.com/a/26197426/1534666

It appears that a ViewFlipperAdapter needs a objectAnimator, not a set.

Example left_in.xml, declared in animator folder

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:propertyName="x"
            android:valueType="floatType"
            android:valueFrom="-1500"
            android:valueTo="0"
            android:duration="600"/>
