Android的ScaleAnimation和TranslateAnimation，如何避免ScaleAnimation运动 [英] Android ScaleAnimation and TranslateAnimation, how to avoid ScaleAnimation movement

问题描述

我有一个AnimationSet与ScaleAnimation内，像这样的TranslateAnimation：

I have an AnimationSet with inside a ScaleAnimation and a TranslateAnimation like this:

TranslateAnimation：

TranslateAnimation:

TranslateAnimation goTopFromRight =
        new TranslateAnimation(0, -(right.getLeft()-top.getLeft()),
                               0,-(right.getTop()-top.getTop()));

ScaleAnimation：

ScaleAnimation:

ScaleAnimation =  setSizeForTop = new ScaleAnimation(1, 2, 1, 2);

和AnimationSet：

and AnimationSet:

bringToLeftFromTopAnimationSet  = new AnimationSet(true);
bringToTopFromRightAnimationSet.addAnimation(goTopFromRight);
bringToTopFromRightAnimationSet.addAnimation(setSizeForTop);

现在的问题是，当我尝试只使用ScaleAnimation，我的项目去我想要的位置，但磨片我现在用的是ScaleAnimation与在AnimationSet的TranslateAnimation，我的产品转化比我更需要，因为如果ScaleAnimation介绍了一些辅助动作ABD我不知道如何删除它们。

The problem is that when i try to use only the ScaleAnimation, my item goes to the position i want, but whe I am using the ScaleAnimation with the TranslateAnimation in the AnimationSet, my item translates more than i need, as if ScaleAnimation introduces some supplementary movements abd I don't know how to delete them.

感谢您的帮助。

推荐答案

要使用ScaleAnimation和TranslateAnimation时避免ScaleAnimation运动，你必须与那些来自ScaleAnimation这样乘以TranslateAnimation参数应用：

To avoid the ScaleAnimation movement when using the ScaleAnimation and TranslateAnimation, you have to multiply the TranslateAnimation parametres with those from ScaleAnimation like this:

TranslateAnimation goRightFromTop;
ScaleAnimation sizeNotUp;

goRightFromTop  = new TranslateAnimation(0,(-( invisibleCenterImageView.getLeft() - imageViewRight.getLeft() ))*(1/0.6667f), 0, (-( invisibleCenterImageView.getTop() - imageViewRight.getTop()))*(1/0.6667f)); 
sizeNotUp       = new ScaleAnimation(1,0.6667f,1,0.6667f,Animation.RELATIVE_TO_SELF, (float)0.5, Animation.RELATIVE_TO_SELF, (float)0.5); 

然后，会让你大吃一惊删除ScaleAnimation运动。

And then, surprise you deleted the ScaleAnimation movement.
