Usage

From source file:Main.java

public static Animation getExpandViewAnimation(final View view, int duration) {

    view.measure(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    final int targetHeight = view.getMeasuredHeight();

    view.getLayoutParams().height = 0;//  w  w  w.jav a 2s . c  o  m

        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            view.getLayoutParams().height = interpolatedTime == 1 ? RelativeLayout.LayoutParams.WRAP_CONTENT
