is it possible that change the image size by animation? what I want to achieve is I have an imageView,and I want to use an animation to resize it.make it bigger ,like I set it 200dip in xml file,after the animation it become 500dip.is that possible?what methods should I use exactly?any help and guideness will be highly appeciate.thank you:D.

or can realize this effect.

EDIT:

I think I need to make it more clear,I have a screen 800dip.and two view ,first is 200dip,another is 600dip.so the second size is calculate by screen size - first size,and I wonder if I change the first imageView size to 600dip by animation,and of course the second imageView become 200 automatic,could that happen?

Your animation changes view hierarchi params so you should apply new layout params (lp) to ImageView.

Create custom animation which will apply new lp to ImageView setting different width/height on every frame. So your image view will increase it's size and move other views. There are a lot examples how to implement this. Take a look at this one.

    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        android.view.ViewGroup.LayoutParams lp = mContent.getLayoutParams();
        lp.height = (int) (mStartHeight + mDeltaHeight * interpolatedTime);
        mContent.setLayoutParams(lp);
    }

  • wow ,this looks like what i want,is that a scaleanimation?should I binding the height with the animation's time? now I use a timer,every 50ms make the height change ,but the effect looks stupid. – Sweet Lady Jan 23 '13 at 01:56
