I am new in Android Development after reading so many tutorials and documentation and spending some time finally i managed to create a navigation drawer with the toolbar. but currently the problem is i can only open drawer by swiping from left side of the screen (not capable open/close drawer with toolbar) i don't know how in onCreateView i can access to navigation drawer id which is not set in onCreateView's setContentView but it is set in onCreate's SetContentView of that class. I use Fragments. i attach my entire code , would appreciate if somebody would say with the button in toolbar ( id burger_btn) how can i change my code to open and close the drawer. Thanks

PS:my intent is with id of burger_btn (the layout of dashboard_activity) open and close the navigation drawer. would appreciate if somebody could help me what changes in code i need to do so.
If you want to open/close Navigation Drawer from Toolbar, then try to change your layout of navigation_drawer
to be:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:height="@dimen/activity_header_height"
android:background="@color/light_green"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.Toolbar>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context=".DashboardActivity">
<FrameLayout android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<fragment android:id="@+id/navigation_drawer"
android:layout_width="240dp" android:layout_height="match_parent"
android:layout_gravity="start"
android:name="com.packageName.NavigationDrawerFragment"
tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
and accordingly, move toolbar related codes from Fragment to Activity
