Android的ScaleAnimation [英] Android ScaleAnimation

问题描述

我想却与点击使用ScaleAnimation视图。我已经成功了动画的影响持续存在后，已与fillAfter完成，但现在的问题是，动画总是从状态0开始（作为视图在XML定义） - 点击视图复位和动画回的状态，这只是第一个动画后。

动画在一个XML定义的：

 ＆LT;规模
  的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
  机器人：插=@机器人：动画/ accelerate_decelerate_interpolator
  机器人：fromXScale =1
  机器人：toXScale =1.5
  机器人：fromYScale =1
  机器人：toYScale =1.5
  机器人：pivotX =50％
  机器人：pivotY =50％
  机器人：时间=1000
  机器人：fillAfter =真
/＆GT;
 

解决方案

我通过不诉诸于XML定义动画，而是做解决了问题。

 动画=新ScaleAnimation（从，到，从，到，Animation.RELATIVE_TO_SELF，0.5F，Animation.RELATIVE_TO_SELF，0.5F）;
 

和从/到我需要扩大它每次调整。我不太确定这是关于性能是一件好事，但它工作得很好。

I'd like to grow a view with each click using a ScaleAnimation. I've managed the effects of the animation persist after it has finished with the fillAfter, but the problem now is, the animation always starts from state 0 (as the View is defined in the XML) - on click the view resets and animates back to the state it was just after the first animation.

The animation is defined in an XML:

<scale 
  xmlns:android="http://schemas.android.com/apk/res/android" 
  android:interpolator="@android:anim/accelerate_decelerate_interpolator" 
  android:fromXScale="1" 
  android:toXScale="1.5" 
  android:fromYScale="1" 
  android:toYScale="1.5" 
  android:pivotX="50%" 
  android:pivotY="50%" 
  android:duration="1000" 
  android:fillAfter="true" 
/>

解决方案

I solved the issue by not resorting to animation defined in the XML, but rather doing

anim = new ScaleAnimation(from, to, from, to, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

and adjusting from/to each time I needed to expand it. I'm not so sure that's a good thing regarding performance, but it works nicely.
