btw this is what i'm doing in onFinishInflate() before setting
visibility to GONE:
ViewGroup.LayoutParams params = content.getLayoutParams();
if (MeasureSpec.getMode(params.height) == MeasureSpec.UNSPECIFIED) {
contentHeight = params.height;
} else {
content.measure(params.width, params.height);
contentHeight = content.getMeasuredHeight();
}
content.setVisibility(GONE);
