Unable to hide Toolbar while scrolling RecyclerView, possible cause?

Unable to hide Toolbar while scrolling RecyclerView, possible cause? - android

I am trying to hide the ToolBar as the RecyclerView gets scrolled, however, ToolBar doesn't hide or move at all. This is how I implemented it:
<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">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:background="?colorPrimary"
android:elevation="#dimen/margin_8"
android:layout_width="match_parent"
android:id="#+id/appbar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
app:layout_scrollFlags="scroll|enterAlways"
android:layout_marginLeft="#dimen/list_toolbar_side_margin"
android:layout_marginRight="#dimen/list_toolbar_side_margin"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:background="?attr/colorPrimary">
<TextView
android:id="#+id/titleText"
android:text="#string/app_name"
android:gravity="start|center"
android:textSize="19sp"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/homeTeamRView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:scrollbarStyle="outsideOverlay"
android:paddingLeft="#dimen/list_side_margin"
android:paddingRight="#dimen/list_side_margin"
android:paddingBottom="#dimen/margin_16" />
</FrameLayout>
How to fix ?

To solve this issue please add in Toolbar widget (android.support.v7.widget.Toolbar):
app:layout_scrollFlags="scroll|enterAlways"

<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"
app:layout_scrollFlags="scroll|enterAlways"
/>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_eez_dine_home" />
As like above

How to fix a gap between AppBarlayout and TabLayout

I'm trying to use a AppBarLayout with Toolbar a TabLayout component and a Viewpager, but I'm getting a black gap between toolbar and tablayout, and not really sure why. I've taken a look some examples of here and they don't work.
I put an image of my problem.

That doesn't seem to be a good practice-design in my view. You used CoordinatorLayout and TabLayout inside it and so much more issues.
Instead, use CoordinatorLayout as the root layout and after AppBarLayout as it's child, then Toolbar and TabLayout inside AppBarLayout.
So, the structure will be:
<CoordinatorLayout
<AppBarLayout
<Toolbar/>
<TabLayout/>
</AppBarLayout>
<ViewPager/>
<CoordinatorLayout/>
After that, use ViewPager inside CoordinatorLayout like this and add the following line of code:
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>

It's actually because of two AppBarLayouts you have which android might not recognize the layout you have written.
Simply, remove the other AppBarLayout and make your layout like this:
<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="#color/colorToolbar"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp">
<ImageView
android:layout_width="#dimen/_40sdp"
android:layout_height="match_parent"
android:src="#drawable/logo_shopline" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="ShopLine"
android:gravity="center"
android:textSize="#dimen/_18sdp"
android:textColor="#color/colorShopLineText"
android:paddingLeft="#dimen/_2sdp" />
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="#dimen/custom_tab_layout_height"
android:layout_gravity="bottom"
app:tabMode="fixed"
app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>

Please correct the line "layout_below"
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/appBarLayout"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

make BottomNavigationView in bottom even if i use layout_scrollFlags to scroll Tollbar

My problem is BottomNavigationView never shows unless I scroll up.
So when I scroll up toolbar is hidden and my BottomNavigationView shows up.
I want it to stay at then bottom.
So i think my problem is with app:layout_scrollFlags.
main.xml

Move your BottomNavigationView outside of your CoordinatorLayout. It worked for me.
Something like:
<RelativeLayout 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:background="#color/colorPrimary"
app:itemIconTint="#color/cardview_light_background"
app:itemTextColor="#color/cardview_light_background"
app:layout_scrollFlags="scroll|snap"
app:menu="#menu/personal_navigation_items"/>
<android.support.design.widget.CoordinatorLayout

ViewPager with Toolbar and TabLayout has wrong height

I have a ViewPager below an AppBarLayout (with a Toolbar and a TabLayout). I cannot understand why the height of the loaded fragments is more than the available space, even if there are no elements so big, making the tab scrollable.
This is the main layout 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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
As you can see in my Fragment I have a Button with a layout_alignParentBottom but I guess it's stretching the height of the viewpager too much.
Here the layout from the design view:

you can try to add a LinearLayout between AppBarLayout and ViewPager. It works for me. :)
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"/>
</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" />
</LinearLayout>

Adding a padding to the ViewPager did the trick for me:
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="?attr/actionBarSize"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
Note that the padding has the exact same size as the toolbars height.
Instead of ?attr/actionBarSize, ?actionBarSize is also valid.

Try with this.
Here you need to declare android:fillViewport="false" property in Tab Bar.
<android.support.design.widget.CoordinatorLayout 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">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Do change here in Tab Bar.
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="false" />
EDIT 1:
This is what working for me Refer this.

If you need a fixed toolbar without scrolling, then you can remove CoordinatorLayout and AppBarLayout from the layout design and use RelativeLayout instead. It is support library bug, and has no solution upto this date. You can simply use following layout code for ViewPager along with Toolbar and TabLayout. ViewPager won't overflow in this case as it has been pointed out in question.

Hope it helps someone!

I have used Relative layout inside of CoordinatorLayout
<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/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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|snap"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="false" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/appbar"
/>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

You have to keep the TabLayout outside the AppBarLayout.
Something like this.
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/home_tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
app:tabGravity="fill"
app:tabIndicatorColor="#color/primary_blue_dark"
app:tabMode="fixed"
app:tabSelectedTextColor="#color/primary_blue"
app:tabTextColor="#color/primary_blue_light"
app:tabTextAppearance="#style/tab_layout_font_style"/>
<android.support.v4.view.ViewPager
android:id="#+id/home_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_horizontal"/>
This worked for me.

For me the only sollution that worked with a Coordinator Layout, so that Viewpager layout_height stays within limits was adding layout_behaviour to the Toolbar, like this:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/colorPrimary"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:popupTheme="#style/AppTheme.AppBarOverlay">
Probably too late for you, but maybe it helps someone else.
This didn't bother me when I started my app, but later when I wanted to add a snackbar on another tab, the snackbar was only visible if I scrolled the page.

I solved this problem by changing android:layout_height="wrap_content" to
android:layout_height="0dp"
and setting
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#id/tl_WelcomeTabs"
in the ViewPager's XML attributes. 0dp in this case means something like match_constraint.
For example this layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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.support.design.widget.TabLayout
android:id="#+id/tl_WelcomeTabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"
>
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start"
/>
<android.support.design.widget.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Mission"
/>
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="#+id/vp_welcomePager"
android:layout_width="wrap_content"
android:layout_height="0dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#id/tl_WelcomeTabs"
/>
</android.support.constraint.ConstraintLayout>
Left image: android:layout_height="wrap_content" right image: android:layout_height="0dp"
tldr;
Change
android:layout_height="wrap_content"
to
android:layout_height="0dp"
and set layout_constraintBottom_toBottomOf and layout_constraintBottom_toBottomOf in the ViewPager's XML attributes.

Override behavior of your view pager wit, and add your view pager to this.layouts
override fun onDependentViewChanged(parent: CoordinatorLayout, child: View, dependency: View): Boolean =
super.onDependentViewChanged(parent, child, dependency).also {
layouts.forEach { it.setPadding(it.paddingLeft, it.paddingTop, it.paddingRight, it.top) }
}

AppBarLayout cannot scroll

android:layout_height="match_parent"
tools:layout="#layout/fragment_hotpost"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
when I use this layout,AppBarLayout cannot scroll,I think the key of this problem is that I set windowTranslucentNavigation to true; How to make it when I still want the navigation be transluncet.
If I set the appBarLayout "android:fitsSystemWindows="true",the AppBar just show half although at this time, it can scroll.
appbar show half when enter
translucent navigation
