I'm building a simple Android app with a viewpager. When I add a floating button in the main activity, he is well placed at the bottom-right of the screen.
But when I add this exact same button inside a fragment of a viewPager, the button goes BEHIND the virtual "soft keys" of my HTC One M8. Look at that (screenshoot with the two buttons):
screenshoot of the app with the floating buttons
So I've find the origin of the problem, but I don't know how to resolve it: the coordinator layout is OK (it stop before the soft keys) but the viewpager inside is not OK (it continues behind the soft keys). How to make it stop at the end of his container, the coordinator layout ? Why the Viewpager is doing that ?

I share with you the code of the mainActivity, containing the viewpager. I've used "match_parent" so I don't understand why it don't stop at the end of the parent:

I am using the following code to hide my toolbar when I scroll on my main activity and it works perfectly. Though, I want to change its behavior a little:

I want the toolbar to only show when the user reaches the far top of the view. I have a recyclerview that has a lot of rows. I want the user to be able to go up and down without being bothered by the toolbar unless he reaches the very top of the view. How can this be done? Thanks.
Edit: edited the code.
in content_main.XML use android.support.v4.widget.NestedScrollView instead of ScrollView.
also use app:layout_behavior="#string/appbar_scrolling_view_behavior" inside android.support.v4.widget.NestedScrollView like below.
<android.support.v4.widget.NestedScrollView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/textone"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="hello world"
android:textSize="25dp"
android:textStyle="bold" />
/// Add your other code here
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
reference from hear : How to hide ToolBar when i scrolling content up in android
I'm using the layout below, The CoordinatorLayout holds inside it AppBarLayout (With Toolbar and TabLayout inside it) and a placeholder RelativeLayout, so I could add and replace fragments on it.
I'm experiencing margin errors, the fragments I add on the RelativeLayout will always over expand beyond the bottom of the screen (in the amount similar to the size of the AppBarLayout height), I've tried setting it's height to wrap_content and match_parent, in both cases it goes overboard.
if I remove the app:layout_behavior="#string/appbar_scrolling_view_behavior" from the RelativeLayout the top of it will be under the AppBarLayout which is also not the desired outcome.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

I have figured out the problem on showing fragment below toolbar when using the coordinator layout. The problem in my case is:
In this image it shows the Fragment is overlapped by Toolbar.
Now just put your AppBarLayout and FrameLayout inside LinearLayout like below,
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/mainappbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Now your problem is solved. And it will be like this.
The final image.
You will also see this issue if you have a ScrollView inside the fragment. So make sure you use a NestedScrollView instead:
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
Had the same issue. Changing RelativeLayout to FrameLayout with parameter app:layout_behavior="#string/appbar_scrolling_view_behavior" solved my problem.
<FrameLayout
android:id="#+id/main_fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
The issue has been solved by updating the recyclerview library (to com.android.support:recyclerview-v7:22.2.0)
The fragment I was loading had a recyclerview in it.
I have spent some time trying to implement this, and did my fair bit of research but couldn't make it work.
In the cheesesquare example by Chris Banes, he makes the toolbar scroll away when the ViewPager is scrolled. The ViewPager is included directly in his drawer layout, just before the NaviagtionView.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fitsSystemWindows="true">
<!-- THIS CONTAINS COORDINATOR LAYOUT with APPBAR LAYOUT + VIEWPAGER -->
<include layout="#layout/include_list_viewpager"/>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header"
app:menu="#menu/drawer_view"/>
</android.support.v4.widget.DrawerLayout>
The include_list_viewpager file is this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
android:layout_width="match_parent"

<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_done"/>
</android.support.design.widget.CoordinatorLayout>
I would like to have a FrameLayout (or NestedScrollView) instead of the ViewPager. Then, I could dynamically load fragments in it as the user clicks on the drawer layout items, and all of them would have a nice animated Toolbar. So far, I'm not able to make the Toolbar scroll away when operating in the invoked fragments. I wonder if it is at all possible.
Has anybody achieved this? Any pointer is greatly appreciated.

CoordinatorLayout must be the parent of all views. DrawerLayout gets the layout_behavior. Since you want to interact with the elements of viewpager, it needs to be in the top view of the DrawerLayout.
I need my main activity to have a drawer menu which switches between different fragments. I also need the main fragment have 3 tabs, each for a different fragment.
With the new design support library, I got confused about how to accomplish such structure by XML (Because the TabLayout is inside the AppBarLayout but the viewPager which holds the different Tab fragments is not).
Right now what I have is the tabs switching fragments (using a FragmentPageAdapter) and a drawer that does nothing...
Here's the code of the main layout:

I use getSupportFragmentManager().beginTransaction().replace(container, fragment).commit to display the fragment, but the drawer did not display correctly like the pic.
How to fix this problem?

The second fragment in ViewPager is transparent, so we can see the drawer is under the fragment.
I'm not sure why that happened since I've also have the same structure but never encountered that bug.
First make sure your container var is pointing to the correct container ID (I assume it is, though just to be sure).
Also try setting android:fitsSystemWindows="true" in your DrawerLayout.
