Toolbar doesn't hiding while scrolling - android

trying to hide toolbar on listview scroll by using appbar_scrolling_view_behavior + scroll flags, but has no result, this is xml code, can't understand what's wrong with this

The ListView doesn't have the nested scrolls enabled by default. Use
ViewCompat.setNestedScrollingEnabled(listView, true);
to enable it.
Be aware that this will from from lollipop onwards . If you want to support older versions of android you should use a RecyclerView

ListView doesn't support nested scrolling
Use RecyclerView instead of ListView and enable nested scrolling in RecyclerView

Best practice is to use RecyclerView with app:layout_behavior="#string/appbar_scrolling_view_behavior" inside CoordinatorLayout.

Toolbar doesn't responsive to scroll events

I want to hide/show the Toolbar when ListView is scrolling. I have CorrdinatorLayout with Toolbar included in. I add the app:layout_scrollFlags="scroll|enterAlways" attribute to the Toolbar. Then I have Listview inside content_min layout with RelativeLayout with app:layout_behavior="#string/appbar_scrolling_view_behavior" attribute. I included the content_main layout inside CoordinatorLayout -Toolbar not responsive to scroll events on listview. Does this Feature work with RecyclerView only and not listview?

The scrolling behavior works with RecyclerView but not out-of-box with ListView. This is because the scrolling behavior needs a scrolling component that implements the NestedScrollingChild interface. This interface is implemented by RecyclerView but not ListView.
My recommendation would be to convert your ListView adapter to a RecyclerView adapter and use RecyclerView.
Supposedly there are some ways to put a ListView inside a NestedScrollView which will give the scrolling behavior. I don't recommend this, but if you search SO you can find some solutions for wrapping your ListView inside a NestedScrollView and getting the toolbar to scroll.

Recycler view Inside NestedScrollView with CoordinatorLayout

Below is the code snippet, can someone please help me? My collapsing toolbar is not collapsing at all. Intended behavior is : as I scroll up, the toolbar should collapse from 168dp to 56dp. But it is not collapsing at all.
Thanks in advance.

EDIT:
I played with your layout. You have to use NestedScrollView in order to make your layout follow scroll behavior of CollapsingToolbarLayout. Following is the working xml code:
<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:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/one_primaryColor">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="168dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="parallax">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/app_name"
android:src="#drawable/logo" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_vertical"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
But there is an issue with this approach. If you put RecyclerView inside NestedScrollView when root parent is CoordinatorLayout. Recycler's content won't be displayed, although all the adapter methods are called. Reason behind is the nesting of scroll layout inside scroll. Most probably Recycler's layout is not rendered due to this reason. For that, work around has been followed from this post.
In your code, use WrappingLinearLayoutManager class as layout manager for recycler view.
//Your custom adapter
Adapter adapter = new Adapter(cursor);
adapter.setHasStableIds(true);
mRecyclerView.setAdapter(adapter);
mRecyclerView.setNestedScrollingEnabled(false);
int columnCount = getResources().getInteger(R.integer.list_column_count);
WrappingLinearLayoutManager wrappingLinearLayoutManager =
new WrappingLinearLayoutManager(columnCount, LinearLayout.VERTICAL);
mRecyclerView.setLayoutManager(wrappingLinearLayoutManager);
This should solve your problem. If it still doesn't work, I can upload it somewhere for you.
Just in case anybody else bumped into the same problem, I'm gonna post the solution to my issue. The problem was with the support-library version, I was using 22.0.0. In this version, the SwipeRefreshLayout does not support CollapsibleToolbar behavior, it was a bug that got resolved in the 23.0 version. So, I updated my support - libaries to 23.0.0 and it got resolved! yeay!

Disable toolbar scrolling

I have the current setup:
<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/coordiator_layout_in_main"
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:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.design.widget.NavigationView
android:layout_width="170dp"
android:layout_height="match_parent"
android:fitsSystemWindows="true"/>
<FrameLayout
// I place a fragment containing a viewpager containing fragments that contain a recyclerview....
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#+id/nav_view">
</FrameLayout>
</RelativeLayout>
<FrameLayout
android:id="#+id/settings_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible">
</FrameLayout>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_refresh"
app:layout_anchor="#id/coordiator_layout_in_main"
app:layout_anchorGravity="bottom|right|end"
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.

tools:showIn="#layout/app_bar_home_screen"
android:id="#+id/content_frame"
android:background="#android:color/white"
tools:context="com.test.app.HomeScreenActivity">
</RelativeLayout>
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)

Android Design Library: SwipeRefreshLayout don't detect swipe over CollapsingToolbarLayout

Has anybody used this sort of thing?
As stated in AppBarLayout docs, it has to be direct child of CoordinatorLayout
This view depends heavily on being used as a direct child within a
CoordinatorLayout. If you use AppBarLayout within a different
ViewGroup, most of it's functionality will not work.
Thus, I'm not sure where the SwipeToRefreshLayout has to be included to work together with the CollapsingToolbar, as NestedScrollView has to be direct child too.
Here is another response that helps to attach the SwipeRefreshLayout and activate it only when the appBar is uncollapsed, but they are not using a NestedScrollView, which doesn't work for me :(
EDIT I found a solution for my problem: The ListView I used, had to be set as nested scroll instead of put it inside a NestedScrollView, or replaced with RecycleView:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
listView.setNestedScrollingEnabled(true);
}
So, a solution for your issue should be to wrap the NestedScrollView inside the SwipeRefreshLayout.

AppBarLayout with FrameLayout container as scrolling content doesn't work

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"

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

and toolbar:

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>
