match_parent not performing as expected

match_parent not performing as expected

I imagine this should be a fairly easy one to answer, if you understand
XML Layouts better than I do that is. I don't seem to get what I was
thinking I should when using the match_parent layout_height.
I have a LinearLayout root element with android:orientation="vertical".
Inside this LinearLayout I want three elements: - TextView - ListView -
TextView
For both the TextViews I set android:layout_height="wrap_content" so that
they will be only as tall as is necessary to display their contents. The
thing is, I want the one TextView to sit at the top of the form, the other
one to sit at the bottom of the form while the ListView fills up whatever
space is available on the form. So here is what my xml layout looks like:
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="30sp"
android:text="Top TextView" />
<ListView
android:id="@+id/listView_Species"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="30sp"
android:text="Bottom TextView" />
But it doesn't work. Here's what I get. I've selected the ListView so that
it will be highlighted. Notice how it extends all the way to the bottom of
the form, pushing the bottom TextView off the form.
When I change the layout_height property of the ListView to some fixed
value, like 180dp, this is what the form looks like. I'm just posting this
to prove that the bottom TextView is there but I still don't know how to
get it to be fixed to the bottom of the screen while the ListView takes up
whatever space remains, but in between the two TextViews.

Thanks in advance.
