Usage

From source file:Main.java

public static void expand(final View v) {

    final int targtetHeight = v.getMeasuredHeight();

    v.getLayoutParams().height = 0;/*from   w  w  w.  jav  a 2s. co 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();
