gmail like Progress bar functionality

I am creating a gmail like progress bar functionality. There seems to be some space between the actionbar and the progress bar.
Following is the code
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ProgressBar
android:id="#+id/progressBar1"
style="?android:attr/progressBarStyleHorizontal"
android:indeterminateOnly="true"
android:layout_width="wrap_content"
android:layout_height="?android:attr/actionBarSize" />
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

DrawerLayout should contain only two children: FrameLayout for your content and fragment for drawer. Thus ProgressBar should be located inside dynamically created content.

To add a navigation drawer, declare your user interface with a DrawerLayout object as the root view of your layout. Inside the DrawerLayout, add one view that contains the main content for the screen (your primary layout when the drawer is hidden) and another view that contains the contents of the navigation drawer. for more Creating a Navigation Drawer.

Did you add the newest version of it? v4 support libary is famous to cause problems if used in wrong version/dependency.

Error strange line between navigation list and fragment DrawerLayout

This strange line appears in my view and don't know the reason
Edit 1: XML
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="320dp"
android:layout_height="match_parent">
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector"
android:background="#color/list_background"/>
</android.support.v4.widget.DrawerLayout>

Go on your XML file, take the DrawerLayout and cut it and put it on the tag before... so you will be able to see how it's designed.
So, put your LinearLayout of the DrawerLayout inside your visible view, edit it, and put it away again.

Sorry all, My Mistake. The shadow was causing this problem
mDrawer.setDrawerShadow(R.drawable.drawer_shadow_rtl, GravityCompat.END);

how to use multiple fragments in the main content view of navigation drawer

I want to show two fragments (one listfragment and other is details fragment) in the main contentview of navigation drawer like below:
But AFAIK, there can be only one view in the main contentview of drawerLayout. So how can achieve this?

Anything you put inside the FrameLayout will be in the main content view.
You can put whatever you want (including multiple Fragments) inside this FrameLayout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- YOUR CONTENT HERE -->
<!-- Could be layout with multiple views or fragments -->
</FrameLayout
<!-- The navigation drawer -->
<ListView android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
