Android layout animation question

I'm trying 开发者_如何学JAVAto animate a transition but it's not giving me the correct results

I have a layout that looks like this:

• LinearView Root
  • ScrollView Groups
    • LinearView
      • Tile1
      • Tile2
      • Tile3
  • ScrollView SubGroups
    • LinearView
      • Tile4
      • Tile5
      • Tile6

Root's orientation is set to horizontal and both Groups and SubGroups has a width and height set to parent fill.

What I want is to animate Groups translating to the left out of the screen so that only ~40 dp is still showing, and SubGroups translating to left right behind Groups, so that only a sliver of Groups is shown and 90% of SubGroups is visible.

Is this possible? Thanks for any help!

i think you mean to do like this :

TranslateAnimation animateGroups = new TranslateAnimation(0,widthScreen - 40 , 0 , 0);
animateGroups.setDuration(1200);
animateGroups.setFillAfter(true);

TranslateAnimation animateSubGroups = new TranslateAnimation(0,widthScreen - 10 , 0 , 0);
animateSubGroups.setDuration(1200);
animateSubGroups.setFillAfter(true);

scrollViewGroups.startAnimation(animateGroups);
scrollViewSubGroups.startAnimation(animateSubGroups);

Note : you can get the screen Dimensions by using DiplayMetrics class , and if you want to convert the pixels to dp , refer this

EDIT : Change the place of your Views after the Animation end to do this , you should add a Listener On your animation ,

animateGroups.addAnimationListener(AnimationListener);

and override the method like this :

 @Override
 public void onAnimationEnd(Animation animation){
scrollViewGroups.setPadding(0, 0 , screenWidth-40 , 0 ) ;
//or you can set the Margin like this(i supposed that your scrollView is in a RelativeLayout 
RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)scrollViewGroups.getLayoutParams();
params.setMargin(0, 0 , screenWidth-40 , 0);
scrollViewGroups.setLayoutParams(params);
}
