How to remove scrolling behavior for child AppBarLayout/TabLayout only? - android

I have a main activity that I use for all my activities which has this layout:
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
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="wrap_content">
<android.support.v7.widget.Toolbar
style="#style/ToolBar"
android:id="#+id/toolbar"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
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.design.widget.CoordinatorLayout>
And inside of one of my fragments I have this layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<android.support.design.widget.AppBarLayout
android:id="#+id/tabs_app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
style="#style/TabLayout"
app:tabIndicatorHeight="0dp"/>
</android.support.design.widget.AppBarLayout>
</LinearLayout>
Is it possible I can disable the Scrolling View Behavior for the #+id/tabs_app_bar_layout only? Basically I have two AppBarLayouts, one for the Toolbar and one for bottom navigation tabs. I want the scrolling view behavior to only affect the Toolbar.
What is the best way I can disable the scrolling behavior for only certain child views?

Toolbar overlaps other content

I have a ViewPager that horizontally scrolls through multiple fragments, however, I've added a toolbar but it overlaps the ViewPager content.
I know there are other similar questions asked here, nothing worked for me, unfortunately.
this is the main_view.xml
<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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
Probably I should add another layout somewhere, but I'm not sure where. A hint would be nice, since I've been struggling with this for the last couple of hours.
Implement like this
<?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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/appbarlt">
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_below="#+id/appbarlt"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
Give relation to your viewpager with appbar when using Relative Layout.
RelativeLayout is a view group that displays child views in relative positions. The position of each view can be specified as relative to sibling elements (such as to the left-of or below another view) or in positions relative to the parent RelativeLayout area (such as aligned to the bottom, left or center).
Try this code:
<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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary" />
</android.support.design.widget.AppBarLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/appbar"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</RelativeLayout>
use this in below layout of Toolbar layout
android:layout_marginTop="?attr/actionBarSize"

AppBarLayout overlaps ConstraintLayout

I have an AppBarLayout nested inside of a CoordinatorLayout
<?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"
tools:context="com.example.michael.blemanager.Activities.ColorPickerActivity.Color1">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBar"
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>
<include layout="#layout/content_color1"/>
</android.support.design.widget.CoordinatorLayout>
Here is the included layout content_color1
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.michael.blemanager.Activities.ColorPickerActivity.Color1"
tools:showIn="#layout/activity_color1">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/default_background"
>
/....
</LinearLayout>
</android.support.constraint.ConstraintLayout>
Now for some reason the AppBarLayout overlaps the ConstraintLayout
See where the tool bar overlaps the color circle? How do I prevent the overlap?
Wrap your include tag inside a FrameLayout using layout_behavior of appbar_scrolling_view_behavior like this:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<include layout="#layout/content_color1"/>
</FrameLayout>
Change CoordinatorLayout to ConstraintLayout.
I had the same problem and that worked for me.

Hiding toolbar & tablayout tabs on scrolling up

I've tried to clone the Google Playstore UI.
So, I've a NavigationView, CoordinatorLayout -> AppBarLayout -> Toolbar, TabLayout, ViewPager. A tab has a layout where there are n horizontal RecyclerViews within 1 vertical RecyclerView.
My questions:
Toolbar gets hidden on scrolling up iff the areas of the vertical list where the horizontal list items aren't visible (the gray background in the screenshot attached) are touched to scroll. If I am scrolling up by touching the inner list the scrolling takes place but the toolbar doesn't hide.
How do I hide the tab header as well on scroll up.

How to use Custom Toolbar in entire app

I have made Toolbar using coordinate toolbar in my app so that i can hide toolbar while scrolling . I also have ViewPager inside it . So when user scroll only Toolbar hides and tabs stick to the top . But in other activity i just want to display toolbar what is the better way to that ?
I am sharing my coordinator layout 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.design.widget.AppBarLayout
android:id="#+id/AppBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<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="?attr/actionBarSize"
android:background="#color/orange"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#color/white">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/MyTabLayout"
style="#style/TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
app:tabTextAppearance="#style/AppTabTextAppearance">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/MyViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/MyTabLayout"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
></android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>
Create a separate layout for toolbar only.
toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<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="70dp"
android:background="#color/white"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#color/white">
</android.support.v7.widget.Toolbar>
Then now its in anywhere in your layout.
<?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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/AppBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include
layout="#layout/toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<android.support.design.widget.TabLayout
android:id="#+id/MyTabLayout"
style="#style/TabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
app:tabTextAppearance="#style/AppTabTextAppearance">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/MyViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/MyTabLayout"
app:layout_behavior="#string/appbar_scrolling_view_behavior"></android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>
If you just want to display Toolbar inside other Activities, you can add the Toolbar to any root layout of the respective Activity like LinearLayout or RelativeLayout (which ever suits your app's needs).

<include> FrameLayout and App/Action Bar Colliding

I have weird problem of colliding
My main xml
<?xml version="1.0" encoding="utf-8"?>
<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">
<include
layout="#layout/content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="250dp"
android:background="#DDDDDD"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="#menu/activity_main_drawer"/>
</android.support.v4.widget.DrawerLayout>
My content.xml
<?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"
tools:context=".main.MainActivity">
<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">
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
Adding android:layout_marginTop="?attr/actionBarSize" this to all fragment layouts solves the problem but why? I think it is because of include technique that is used in main layout but since toolbar is always there and framelayout is another widget, but it starts calculationg from top of app bar.
Because you are using a CoordinatorLayout as parent of your Fragment layout.
You haven't any explicit behavior defined there so it will use his default behavior, that's why the Fragment layout is "under" your AppBarLayout.
A simple way to solve this is to add the layout_behavior attribute to fragment_container:
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
