Usage

From source file:Main.java

public static void animCollapse(final View v) {
    final int initialHeight = v.getMeasuredHeight();

    Animation a = new Animation() {
        @Override/*  w  ww  .  j a  v  a2 s .  co m*/
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            if (interpolatedTime == 1) {
                v.setVisibility(View.GONE);
            } else {
                v.getLayoutParams().height = initialHeight - (int) (initialHeight * interpolatedTime);
                v.requestLayout();
            }
        }

        @Override

    };

    // 1dp/ms
