Hello I'm attempting to simply put my content below the toolbar but at the moment when I run my application some of the content is hidden behind it when it should be below it.
I have read up about using a frame layout to attempt to separate it but I have come a little stuck. I'm currently using a basic android studio navigation drawer template provided with the software and was wondering what changes I have to make.
My coordinator layout
<android.support.design.widget.AppBarLayout
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:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.design.widget.CoordinatorLayout>
My drawer layout
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
What changes do I need to make?
Many ViewGroups allow their children to overlap. These include FrameLayout, RelativeLayout, CoordinatorLayout, and DrawerLayout. One that does not allow its children to overlap is LinearLayout.
The answer to your question really depends on what the end result should be. If you are trying to just have a Toolbar that is always on screen and some content below it, then you don't need a CoordinatorLayout and AppBarLayout at all, you can just use a vertical LinearLayout with two children:
<LinearLayout android:orientation="vertical" ...>
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
... />
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
... />
</LinearLayout>
Note layout attributes of the FrameLayout.
If you want to do the fancy stuff where the toolbar scrolls on and off the screen as you scroll the content, then you need an AppBarLayout and you need to give your content area a special attribute like this:
<android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
... >
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll"
... />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
... />
</android.support.design.widget.CoordinatorLayout>
app:layout_behavior="#string/appbar_scrolling_view_behavior"
Add this code to your frame tag
As #Brian Hoang and #Karakuri said using the layout_behaviour property:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
seems to be a very good solution. Even if you don't have any animations at the moment but you plan to have in the future then you can still keep the CoordinatorLayout and an AppBarLayout in case you want to add animations in the future.
What the property seems to do in general from my understanding, is to calculate the height of the whole AppBarLayout UI component. The UI component that uses the layout_behaviour property with the #string/appbar_scrolling_view_behaviour will automatically be shown exactly below the AppBarLayout regardless of what the height is.
In this way there is no need to hardcode any top margins in the UI that is supposed to be under the AppBarLayout.
In the code below the include_app_bar_with_tabs_layout (AppBarLayout) has a fixed height of 200dp (it can be wrap_content or anything else). Then the RelativeLayout that contains the content of the screen uses the layout_behaviour property.
Have a look at the code and UI image below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<include
layout="#layout/include_app_bar_with_tabs_layout"
android:layout_width="match_parent"
<!-- this can be anything, even wrap_content -->
android:layout_height="200dp" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/Green"
<!-- this tells it to be below the include_app_bar_with_tabs_layout (AppBarLayout) -->
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/adView" />
<com.google.android.gms.ads.AdView

</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

So far I've managed to implement AppBarLayout and Toolbar with scroll flags and AppBar scrolling behavior and it all works great. My final goal is to implement something like this:
Netflix App Example
As you can see AppBar is transparent and the content is behind it. And everything else works perfectly.
From my observations when I put app:layout_behavior="#string/appbar_scrolling_view_behavior" (In my case I used app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior") tag CoordinatorLayout does not let me overlap Views (In this case AppBar should overlap my content).
This is my XML:
<androidx.drawerlayout.widget.DrawerLayout
android:id="#+id/drawerLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:fitsSystemWindows="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior">
<fragment
android:id="#+id/fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:navGraph="#navigation/root_nav_graph"
app:defaultNavHost="true"
/>
</FrameLayout>
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$Behavior"
>
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolBar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways|snap"
/>
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
The fragment holds layout with NestedScrollView as a Root.
Remove the attribute
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"
from the Frame Layout. Also, set the attribute android:background="#android:color/transparent" to your toolbar.
I am using a CoordinatorLayout that contains an AppBarLayout and a FrameLayout that will hold different fragments at runtime. I need the FrameLayout to always be below the AppBarLayout without using the appbar_scrolling_view_behavior attribute. For reasons (namely trying to get a RecyclerView and a floating footer button to work on the Fragments) I am applying this attribute on the RecylerView in the Fragment. Scrolling works fine except the FrameLayout thinks it should have the full height of the screen. This is usually fixed by the appbar_scrolling_view_behavior, but I cannot use that here. I tried layout_anchor and layout_anchorGravity to literally no effect.
Any ideas?

app:layout_behavior="com.material.widget.MyFloatingActionButtonBehavior" />
</android.support.design.widget.CoordinatorLayout>
Now everything work as expected if I scroll inside the framelayout that contains the fragments, the toolbar slides in and out as I want
Now the point is that I would like to disable the toolbar sliding in and out if I scroll the NavView which is on the side of the framelayout (and inside the relativelayout)
But no matter if I remove all scrolling behaviors the toolbar keeps on sliding in and out (only way to disable it is remove the scroll flags form the appbarlayout, but that disable all sliding in and out of the tolbar)
Please what am I missing here? Aren't the scolling behaviours supposed to pass the scroll events to the CoordinatorLayout?
Unfortunately, NavigationView contains NavigationMenuView which is RecyclerView and so it supports nested scrolling and moves AppBarLayout when scrolled. The best way to solve this problem would be to move NavigationView out of CoordinatorLayout. If it's not possible you can try the following code, which I haven't tested.
final RecyclerView navigationMenuView =
(RecyclerView) findViewById(R.id.design_navigation_view);
navigationMenuView.setNestedScrollingEnabled(false);
Please take into account that even if this code works it can break when the Design library is updated.
Move your NavigationView inside a DrawerLayout and the CoordinatorLayout inside the main content of the DrawerLayout.
From docs:
NavigationView is typically placed inside a DrawerLayout.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

Remove this line of codeapp:layout_scrollFlags="scroll|enterAlways" from your ToolBar. Worked in my case.
For anybody who might be interested this is how I dealt with the issue.
I created my custom version of the NavigationView by copying the relevant files form the source,
they are:
NavigationView.java
NavigationMenuItem.java
NavigationMenuPresente.java
NavigationMenuView.java
ThemeUtils.java
Fix the imports so that the new NavigationView points to the newly copied files.
And finally add this setNestedScrollingEnabled(false) to the constructor of NavigationMenuView.
This is because, how #Michael correctly pointed out the NavigationMenuView is a RecyclerView, and as such it passes its scrolling events to the NestedScrollingParent (the CoordinatorLayout), by setting setNestedScrollingEnabled(false) we disable this behaviour and we get the desired result (scrolling the NavView does not expand/collapse the AppBar)
I have search the Stack Overflow beforewise, but haven't found an appropriate answer to my problem.
I have an Android application with the coordinator layout that has a nested ViewPager inside. If I scroll a RecyclerView that is inside of the first fragment in a View pager, the Toolbar is hidden and shown as intended. However, my other fragments in the ViewPager do not have nested scroll, so I would like to show Toolbar if it is hidden on ViewPager page change. I wonder if I can extend the CoordinatorLayout behavior to have it nicely done.
Thanks in advance! I will be happy to provide more details if needed.
The approximate code is (tried to strip all the unnecessary stuff): main_activity.xml
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways" />
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/toolbar" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/tab_layout"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
and a scrolling fragment: fragment.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.v7.widget.CardView
android:id="#+id/add_word_card"
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<RelativeLayout
android:id="#+id/add_word_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/highlight">
<!-- some unrelated stuff -->
</RelativeLayout>
</android.support.v7.widget.CardView>
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_below="#id/add_word_card"
android:layout_width="match_parent"
android:layout_height="match_parent"

I have found a couple of related questions like: this or this. But they focus mostly on layout problems, while I want to understand if it is real to have a nice solution to triggering Toolbar movement on demand.
So it seems that the answer is the following: wrap the Toolbar in AppBarLayout and in the code use something like: appBarLayout.setExpanded(false, true);
This does the trick for me.
I'm trying to use the newest design library to make my toolbar hide/show on scroll. My issue is the scrolling content I have is in the fragment, I'm just injecting it into the FrameLayout container and it doesn't work. Here's my activity:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/layout_toolbar" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
<FrameLayout
android:id="#+id/navigation_drawer_container"
android:layout_width="#dimen/navigation_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
tools:layout="#layout/fragment_nav_drawer_anon" />
and my fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/pull_to_refresh"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout>
<TextView
android:id="#android:id/empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="18sp"
android:fontFamily="sans-serif"
android:color="#color/dark_grey"
android:padding="60dp"/>
and toolbar:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
style="#style/Widget.MyApp.ActionBar" />
I'm following official doc and this demo, and still can't figure out how to make it work.
Replace your FrameLayout with android.support.v4.widget.NestedScrollView
NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
Link to doc
Using FrameLayout as child of CoordinatorLayout works quite well. The toolbar is collapsing like it's supposed to. I had a problem in the beginning, when I used outdated libraries.
Here are the gradle dependencies I'm using right now:
compile 'com.android.support:appcompat-v7:22.2.1'
compile 'com.android.support:cardview-v7:22.2.0'
compile 'com.android.support:recyclerview-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
I'm using FrameLayout with the attribute app:layout_behavior="#string/appbar_scrolling_view_behavior" as a child of CoordinatorLayout in an activity's layout. The FrameLayout serves as container for fragments. My fragment layouts' root elements are either a RecyclerView or a NestedScrollView.
Here is the layout of the activity:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/..."
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
<android.support.design.widget.AppBarLayout
android:layout_height="192dp"
android:layout_width="match_parent"
>
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
>
<ImageView
android:id="#+id/.."
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="#drawable/..."
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_sessions"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
My first fragment's layout looks like this:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="..."
/>
My second fragment's layout looks like this:
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="..."
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="..."
>
...
</android.support.v4.widget.NestedScrollView>
The reason for that behaviour is that the Framelayout doesn't specify a Behaviour. The CoordinatorLayout relies on the child view to handle the Behaviour.
You can read at the bottom here
http://android-developers.blogspot.in/2015/05/android-design-support-library.html
It states that
CoordinatorLayout and custom views
One thing that is important to note is that CoordinatorLayout doesn’t
have any innate understanding of a FloatingActionButton or
AppBarLayout work - it just provides an additional API in the form of
a Coordinator.Behavior, which allows child views to better control
touch events and gestures as well as declare dependencies between each
other and receive callbacks via onDependentViewChanged().
Views can declare a default Behavior by using the
CoordinatorLayout.DefaultBehavior(YourView.Behavior.class)
annotation,or set it in your layout files by with the
app:layout_behavior="com.example.app.YourView$Behavior" attribute.
This framework makes it possible for any view to integrate with
CoordinatorLayout.
Edit: Although FrameLayout is not a custom view, it doesnt specify a behaviour which CoordinateLayout seeks.
In my app it works only with RecyclerView. Maybe you should use RecyclerView instead of ListView.
You can achieve scrolling with Framelayout inside your CoordinatorLayout. For it you have to use app:layout_behavior="#string/appbar_scrolling_view_behavior" inside your frameLayout as well as inside the scrolling view with which you want this collapsing effect.
For ex- If you are inflating RecyclerView inside your frameLayout, then you have to use app:layout_behavior="#string/appbar_scrolling_view_behavior" inside your recyclerrView also.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</Relativelayout>
or,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/bNext"
android:fillViewport="true"
android:scrollbars="none"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!-- your content -->
</android.support.v4.widget.NestedScrollView>
</Relativelayout>
Thus, using this process you can achieve scrolling with frameLayout whether it contains recycler or nestedScrollview.
It's a good question. I too had the same.
Your container FrameLayout is defined right the problem lies with the Fragment. The Fragment should have RecyclerView & not ListView as it is now deprecated.
Example:
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingTop="#dimen/activity_vertical_margin"/>
I use the same structure in my app & it works perfect.
ListView does not implement NestedScrollingChild so it does not work.
RecyclerView does, so it can propagate the scroll to the NestedScrollingParent (the CoordinatorLayout).
You only need to replace
FrameLayout
to
android.support.v4.widget.NestedScrollView
in this way:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/root_coordinator"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways">
<ImageView
android:layout_width="match_parent"
android:layout_height="192dp"
android:scaleType="centerCrop"
android:src="#drawable/header"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<!-- This was before FrameLayout -->
<android.support.v4.widget.NestedScrollView
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="16dp"
android:src="#drawable/ic_drawer_alertas"
app:borderWidth="0dp"
app:fabSize="mini" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_drawer"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_header"
app:itemIconTint="#color/colorAccent"
app:itemTextColor="#color/colorSecondaryText"
app:menu="#menu/menu_main" />
Move the app:layout_scrollFlags="scroll|enterAlways" from the toolbar to the Framelayout. Sorry for being late.
You must add behavior to the scroll view:
<android.support.v4.widget.SwipeRefreshLayout
android:layout_marginTop="5dp"
android:id="#+id/swipe_main"
android:enabled="false"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
android:id="#+id/rvUserProfile"
app:recyclerviewEmptyView ="#layout/ev_home"
app:recyclerviewClipToPadding="false"
android:layout_width="match_parent"
android:layout_height="match_parent"></com.marshalchen.ultimaterecyclerview.UltimateRecyclerView>
</android.support.v4.widget.SwipeRefreshLayout>
