My progress bar hiding behind other layouts

I have included a progress bar in my relative layout, but it is running behind the layout. Is there any way I can bring it in front show that it show when the page is loading.
[Sorry, I'm pasting whole XML file, cause I don't know where to put progress bar! as I'm newbie, I want you to help me. Sorry again!]

android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/nested"
android:layout_marginBottom="#dimen/_45sdp"
app:behavior_overlapTop="#dimen/_34sdp"
app:layout_anchor="#id/appbar"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
