Design wrong of navigation drawer in tabbed Activity

I have a problem with my navigationdrawer of my tabbedActivity.
I have a problem of design if I can say like that.
When I open the navigation drawer, I'd like that he opens like this (this is another activity of my app) :
But instead it opens like this in my tabbed activity :
How can I move down my navigation drawer so it doesn't cut the title of my activity ?
my xml file

You should move your toolbar to outside of the drawerLayout.
Since now the toolbar is having drawerLayout as its parent, that's why its showing like this.

add margin top to your NavigationView

Make this change to your navigation view.

Hide Toolbar on scroll

I know this has been asked before a lot of times, but I’m still not able to get it working. The app:layout_scrollFlags="scroll|enterAlways" parameter exists, but I think it’s got something to do with the nesting. My XML file below:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:fitsSystemWindows="true"
android:id="#+id/mDrawerLayout"
android:layout_height="match_parent"
android:layout_width="match_parent"
tools:context=".MainActivity">
<android.support.design.widget.CoordinatorLayout

android:layout_width="match_parent">
<LinearLayout

app:itemBackground="#color/colorPrimaryLight"
app:itemIconTint="#color/colorText"
app:itemTextColor="#color/colorText"
app:menu="#menu/drawer"/>
</android.support.v4.widget.DrawerLayout>

Remove LinearLayout and add android.support.design.widget.AppBarLayout as a container of ToolBar.
Keep FrameLayout outside of android.support.design.widget.AppBarLayout.
Add app:layout_behavior="#string/appbar_scrolling_view_behavior" to FrameLayout
Update your activity_main.xml as below:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

Hope this will help!

Thanks in advance .

Try to use below code in the RecyclerView.
android:layout_gravity="fill_vertical"

I im just facing the same problem. It seems that this is space is reserved for the upper indicator bar.
For the moment, I have solved with android:fitSystemWindows="false" in the DrawerLayout itself, and in (this is important, you have to change the both) in the first layout content.

FloatingAction default behavior doesn't work

I'm creating an app with a navigation drawer. And over all my fragments there needs to be a Floating Action button. But when I create a Snackbar the floatingactionbutton goes up, but never goes back down.
I don't know what I have done wrong.
My CODE:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

Error with Toolbar

Sorry my bad English.
I have the following "activity_main.xml" file, the problem is that the Toolbar NOT appears, someone tells me how to make her look?
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_height="wrap_content"

</RelativeLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"

android:layout_gravity="start"
app:elevation="4dp"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/menu_main"/>
</android.support.v4.widget.DrawerLayout>
with this other "activity_main.xml" Toolbar appears, but lacks the Navigation Drawer
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res /android"

xmlns:ads="http://schemas.android.com/apk/res-auto"

Try this way it will work
