Answer 1

@Override
public void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) {
    if (this.isExpanded) {
        final int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
        final ViewGroup.LayoutParams params = this.getLayoutParams();
        params.height = this.getMeasuredHeight();
    } else {
       super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}
