Usage

From source file:Main.java

public static void expand(final View v) {
    v.measure(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    final int targtetHeight = v.getMeasuredHeight();

    v.getLayoutParams().height = 0;/* w  ww . j a va  2s  .c o  m*/
    v.setVisibility(View.VISIBLE);
    Animation a = new Animation() {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            v.getLayoutParams().height = interpolatedTime == 1 ? LayoutParams.WRAP_CONTENT
                    : (int) (targtetHeight * interpolatedTime);
            v.requestLayout();
