Android Animation Questions

1.

 1 AnimationSet exitTransition = new AnimationSet(true);
 2         exitTransition.setDuration(1000);
 3         int xoffset=getResources().getDimensionPixelSize(R.dimen.list_width);
 4         int yoffset=getResources().getDimensionPixelSize(R.dimen.topbar_height);
 5         float xscale=(mShelvesView.getWidth()-xoffset)/(float)mShelvesView.getWidth();
 6         TranslateAnimation trans = new TranslateAnimation(
 7                 Animation.ABSOLUTE, 0, Animation.ABSOLUTE, xoffset,
 8                 Animation.ABSOLUTE, 0, Animation.ABSOLUTE, yoffset);
 9         ScaleAnimation scales= new ScaleAnimation(1f,xscale,1f,1f);
10         exitTransition.addAnimation(scales);
11         exitTransition.addAnimation(trans);
12         exitTransition.setFillAfter(true);
13         mShelvesView.startAnimation(exitTransition);

I create an animation ues this code in Android 4.0,and it runs properly.However ,when I run it on Android 3.1 device,the animation process is gone.It directly jump to the last position.

Answers:

add this two lines :

trans.setDuration(1000);
scales.setDuration(1000);

then it will be ok.
