Accurate way to determine the measured height of a view, even before it changed from GONE to VISIBLE

Question

Currently, I have a layout which looks like this. It contains.

• Title text view, and Price text view, which is visible always.
• Description Text View

Answer 1

I accomplished this for my accordion component. I was facing the exact same issue, of expanding my accordion which required the 'destination' height, that is, the height that it would take after the expansion. This returns the correct height:

/***
 * This function returns the actual height the layout. The getHeight() function returns the current height which might be zero if
 * the layout's visibility is GONE
 * @param layout
 * @return
 */
public static int getFullHeight(ViewGroup layout) {
    int specWidth = View.MeasureSpec.makeMeasureSpec(0 /* any */, View.MeasureSpec.UNSPECIFIED);
    int specHeight = View.MeasureSpec.makeMeasureSpec(0 /* any */, View.MeasureSpec.UNSPECIFIED);


    layout.measure(specWidth,specHeight);
    int totalHeight = 0;//layout.getMeasuredHeight();
    int initialVisibility = layout.getVisibility();
    layout.setVisibility(View.VISIBLE);
    int numberOfChildren = layout.getChildCount();
    for(int i = 0;i
