Fragment doesn't respect match parent height when having listview row item has hidden view in it

问题

I am having a weird issue in my app. In one of my app activity I am inflating three fragments in it with tabs. Everything works fine. In the fragment in which I am having problem, I have listview which is inflated using adapter and data fro web service. This also works well. Now the problem is this the row which is inflated in adapter, has a hidden view which has visibility=gone in xml. On tap of imageview from that row I make that layout visible through java code. The problem is layout doesn't become visible on tap. I have even set breakpoint on the onClickListener of imageview and it does execute the line which changes the visibility from gone to visible. I am unable to understand what is causing this issue as I am using the same row xml with same data in other screen and there it is working perfectly.

UPDATE

I got to know what's causing this issue but don't know how to solve this. In my activity I am having three fragments. The view that I provided for fragment(in which fragment will be inflated) is causing main problem. I have set height width to match parent but it is not taking match parent height. If the fragment just includes normal views like textview, imageview then also fragment is shown properly.But the problem is if fragment consists of listview, then it only takes height of the custom row that is supplied to the listview. I am able to scroll complete listview in that space. I don't understand what is causing this behaviour. My Updated code.

Here are the screenshots of the problem

Comparing both images you can see that the hidden view appears in the space of the single row item and is scroll able completely in that space.

Better upshot were targeted at plus for android developers (Cristophe Beils):

"Your ListView must have its height set to match_parent or a fixed size, not wrap_content.

If you need to add another view fixed at the bottom of the ListView as a footer, you need to put both the ListView and the footer View in a vertical LinearLayout and set layout_height to 0dp and layout_weight to 1 on the ListView so that it takes the remaining vertical space."
