Try to add you ProgressBar
to layout with weight.
Instead of
<ProgressBar
android:id="@+id/pbProgress"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true" />
write something like this:
<LinearLayout
android:gravity="center_horizontal"
android:layout_weight="85"
android:layout_width="match_parent"
android:layout_height="0dp">
<ProgressBar
android:id="@+id/pbProgress"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:indeterminate="true" />
</LinearLayout>
update: btw, instead of fill_parent
better use match_parent
