بزرگ کردن ویو با انیمیشن (Animation)

 public class AnimationProgress extends Animation {

    protected final int  originalHeight;
    protected final int  originalWidth;
    protected final View view;
    protected float      perValueHight;
    protected float      perValueWidth;


    public AnimationProgress(View view, int fromHeight, int toHeight, int fromWidth, int toWidth) {
        this.view = view;
        this.originalHeight = fromHeight;
        this.originalWidth = fromWidth;
        this.perValueHight = (toHeight - fromHeight);
        this.perValueWidth = (toWidth - fromWidth);
    }


    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        view.getLayoutParams().height = (int) (originalHeight + perValueHight * interpolatedTime);
        view.getLayoutParams().width = (int) (originalWidth + perValueWidth * interpolatedTime);
        view.requestLayout();
    }


    @Override
    public boolean willChangeBounds() {
        return true;
    }
}

برای فراخوانیش هم از کد زیر استفاده کنید

 AnimationProgress heightAnim = new AnimationProgress(imageView, 0, imageView.getHeight(), 0, imageView.getWidth());

        heightAnim.setDuration(500);

        imageView.startAnimation(heightAnim);
