Like #getMeasuredHeightAndState() , but only returns the raw height component (that is the result is masked by #MEASURED_SIZE_MASK ).

Usage

From source file:Main.java

public static Animation expand(final View v, int duration, boolean startAnim) {
    if (v.getVisibility() == View.VISIBLE)
        return null;

    v.measure(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    final int targetHeight = v.getMeasuredHeight();

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

        @Override
        public boolean willChangeBounds() {
            return true;

    };

    a.setDuration(duration);
