How to put a spinner between a list view and a App Bar

I am currently working on an application to help manage bills. I have an activity that list the bills. I am trying to put a spinner between a list of bills and the title at the top. Is there a way to put the spinner so that it is at the top of the listView but below the app bar.?
This is what the app looks like:
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height"

DISMISS THIS
As suggested in the comments why not use a LinearLayout with vertical orientation and put the spinner as the first child with height wrap_content and then below it the listview with height 0dp and layout_weight set to 1
NEW PROPOSAL
Take a look a this layout. I already tried at a test app:

I have to comment the popup theme because I don't have it.
Also you need to use a theme with .NoActionBar because you're suppling the action bar and on the Activity containing this layout you need to call:
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Was it what you're looking for?

android - collapsing toolbar and fragment layout not working together

In my app I have two fragments and a MainActivity. The activity_main.xml contains a collapsing toolbar which works perfectly for me when the fragments are empty. In my first fragment I fetch json data from a server and put it into a listview inside the fragment activity. The data is fetched and shown correctly, but the listview takes the whole screen and my collapsing toolbar seems to be a little buggy, like sometimes it pops up and disappears and my listview is not scrollable anymore. The two activities aren’t working together at all. Is there a way to make them work together?

You haven't mentioned where the fragments are attached - I assume within the NestedScrollView? If not, that's where they should go.
The problem is most likely the ListView within the fragment - unlike a RecyclerView, it does not implement NestedScrollingChild2 and ScrollingView, which are required for the collapsing toolbar functionality.
Replace the ListView with a RecyclerView and make sure the fragments are within the NestedScrollView that has app:layout_behavior="#string/appbar_scrolling_view_behavior" and it should work.

Use this code.
And also you need to change color of tollbar which swutching fragment.
toolbar.setBackgroundColor(ContextCompat.getColor(getApplicationContext(), android.R.color.transparent));
mFragmentToSet = new HomeDashboardFragment();

How to create a collapsing toolbar with a ViewPager inside?

Can you please tell me where to add the ViewPager and dotindicator(LinearLayout) inside the collapsible toolbar?

The container layout-RelativeLayout of the ViewPager and LinearLayout should be inside CollapsingToolbarLayout. And set the property like this to make it collapsible with scroll events.
app:layout_collapseMode="parallax"
