Usage

From source file:Main.java

    }/*w ww.  j  a  v  a 2s  .c  om*/

    // Older versions of android (pre API 21) cancel animations for views with a height of 0.
    v.getLayoutParams().height = 1;
    v.setVisibility(View.VISIBLE);
    Animation a = new Animation() {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            v.getLayoutParams().height = interpolatedTime == 1 ? RelativeLayout.LayoutParams.WRAP_CONTENT
                    : (int) (targetHeight * interpolatedTime);
