I have xml, which consits of DrawerLayout, CoordinatorLayout with custom views, AppBarLayout, NestedScrollView.
Problem: When content in NestedtScrollView fills, NestedtScrollView scrolls down itself.
All researches like scrollView.setScrollY(0) or custom class for layout_behavior = FixedScrollingViewBehavior didn't help me.
How do i prevent this scrolling

Try to set android:descendantFocusability="blocksDescendants" to the LinearLayout inside NestedScrollView. It works for me.
UPD: beware of using into the layout descendant elements like EditText, which should take a focus: that elements will not take a focus. If you know how to solve this, please let us to know.
An alternative to blocking the focus, is to add a new View that will steal the focus. Put it anywhere above the NestedScrollView, and it should work:
<!--focusStealer, to avoid NestedScrollingView to scroll due to dynamically created views that take the focus-->
<View
android:layout_width="0px" android:layout_height="0px" android:focusable="true"
android:focusableInTouchMode="true"/>
This working for me:
mNestedScrollViewChat.post(new Runnable(){
#Override
public void run(){
mNestedScrollViewChat.fullScroll(View.FOCUS_DOWN);
}
});
This worked for me in Kotlin
nestedScrollView.post { nestedScrollView.fullScroll(View.FOCUS_DOWN) }
add android:descendantFocusability="beforeDescendants" and add and android:focusableInTouchMode="true"android:focusableInTouchMode="true"' in children view of Nested ScrollView
becase nestedScrollView need focus a view before scroll. i try focus a Edittext from children of view to get focus

My problem is delayed response when i slide up the screen to load data. The link is a video of the issue.https://www.youtube.com/watch?v=VaaAl-omBiY
I think this problem is setting behavior.This touch event is a delay passed to RecyclerView.
Please help me this problem has been bothering me for a long time.
this is a bug of supportlibrary,and not fixed in 27.1.0
https://issuetracker.google.com/issues/66996774
try https://gist.github.com/chrisbanes/8391b5adb9ee42180893300850ed02f2, it works
I'm testing the use of Snackbar for the first time and I'm finding a behaviour which I don't understand. My Activity is composed of a Fragment, which is composed of a FrameLayout with a RecyclerView. I'm using Toolbar and Appbar.
When the Snackbar appears it moves the recyclerView up, I don't want it to behave like this, I want the Snackbar to show OVER the RecyclerView without moving it. I can however remove this from the Layout that contains the fragment:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
and then the Snackbar displays as I intend it to but of course my fragment overlaps with the Toolbar. I'm new to CoordinatorLayout so I fail to see how to get the behaviour I want. My full code is below.

We can see here last item is partially visible. How can i fix this?

I'm also having the same problem. In my opinion this happened because you set the AppBarLayout XML attribute android:fitsSystemWindows="true". To solve this i give the RecyclerView margin bottom equal to action bar size
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/recyclerView"
android:layout_marginBottom="?attr/actionBarSize">
#Lester was right problem was RecyclerView's wrap_content height. But changing match_parent was not working because. This layout was added to a fragment and that fragment was declared wrap_content. So I have changed fragment's height and recyclerview's height to match_parent and now problem solved.
<fragment
android:id="#+id/fragment"
android:name="com.example.fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
I had this problem with a RecyclerView inside a ConstraintLayout, and i changed my recyclerview constriants to "0dp" (match_constraint) and had no further trouble.
have a look
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<!-- Title -->
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="#dimen/view_with_press_height"
android:text="#string/taxes_fees_charges"
android:gravity="center_vertical"
android:layout_marginStart="#dimen/general_side_margin"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
/>
<!-- Details Recyclerview-->
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#+id/title"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_marginBottom="#dimen/general_bottom_margin"
app:layout_constraintVertical_bias="0.0"
tools:itemCount="28"
tools:listitem="#layout/tax_details_row" />
</android.support.constraint.ConstraintLayout>
if you want to use the tools:itemCount="28" you will have to import xmlns:tools="http://schemas.android.com/tools" in your XMLfile.
I tried all the available option from most of possible site but I didn't get the solution.
Then, I think can I use bottom padding? And Yes, It's work for me.
I am sharing the code to you.
Nothing more attribute required other than height, width & padding.
android:paddingBottom="?attr/actionBarSize"
<android.support.v7.widget.RecyclerView
android:id="#+id/your id name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="?attr/actionBarSize"
app:layout_constraintTop_toBottomOf="#+id/your field" />
Use RelativeLayout instead of ConstraintLayout.It's working for me.
I'm showing some solution but didn't work
Now I find one easy solution for this cutting off the last item in recycler view
Add your recycler view into LinearLaout
After adding recycler view into Linearlayout add these two Attributes into recycler view.
android:paddingBottom="?attr/actionBarSize"
android:clipToPadding="false"
Now, Your Recyclerview looks like this,
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvQuotes"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginStart="#dimen/_10sdp"
android:layout_marginEnd="#dimen/_10sdp"
android:background="#color/white"
android:paddingBottom="?attr/actionBarSize"
android:paddingTop="#dimen/_10sdp"
android:clipChildren="false"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
tools:listItem="#layout/item_dessert"
android:clipToPadding="false"/>
Easiest but not the best solution. Still works;
Return +1 in the getItemCount() method of your RecyclerView.Adapter implementation and wrap your code in onBindViewHolder method override with a try-catch block.
For others.Disabling nested scrolling in recyclerview also causes this problem in CoordinatorLayout with scrollable toolbar or tablayout. Because when you scroll recyclerview, toolbar or tablayout doesn't scroll.
don't align recyclerview with respect to any view.. simply make it match parent and provide margin from top....this worked for me
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerViewAddresses"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
android:layout_marginTop="#dimen/dimen_120dp"
/>
I'm using android library Android-ObservableScrollView from ksoichiro. I use his sample Flexible Space with viewpager and i modify it.
But there's some problem. You can see in my xml there is 2 android:fitsSystemWindows. One in LinearLayout, and the other in Toolbar. In LinearLayout working good. but in Toolbar is not working. Why this happen?
Thank you. Sorry for my bad english

</FrameLayout>
The android:fitsSystemWindows attribute sets a padding. This means the fitting applies to the child views. You would have to apply this either to your FrameLayout or put the Toolbar into a nested Layout
It's really tricky to make a proper fullscreen layout with views fitted to the screen. I subclassed Fragment where I can declare a content-view which will get padding depending on Status- and/or Navigationbar
I have Activity with bottom navigation bar (via roughike BottomBar library). It's look like this:
When i'm trying to scroll page, bottom bar hides automatically. So, I get this:
I want avoid this effect. I do not want hide bottom bar when I'm just trying to scroll content but all content lies on screen.
But if page contains content more than one screen then bottom bar must hides on scroll (and now it's works fine).
My code doesn't have any listeners for scroll and my xml file looks like this:

</android.support.design.widget.CoordinatorLayout>
I'm looked for solution for my problem but found nothing. What can i do for avoid this effect?
UPDATED:
FAB is inside ViewPager. Layout for tab on screenshot look like this:
<?xml version="1.0" encoding="utf-8"?>

app:bb_behavior="underNavbar"
You have an issue in the following code
<com.roughike.bottombar.BottomBar
android:id="#+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
app:bb_tabXmlResource="#xml/bottom_bar_tabs"
app:bb_activeTabColor="#color/white"
app:bb_inActiveTabColor="#color/bottom_bar_inactive_tab"
app:bb_inActiveTabAlpha="1"
app:bb_behavior="shy|shifting" />
replace the
app:bb_behavior="shy|shifting"
with
app:bb_behavior="underNavbar"
Hope this works for you!
Check your manifest FILE and make sure you're not using full screen theme...However, you can use the following code to hide and show the bar on android higher than API 19. To hide the bar, just change VISIBLE to GONE, and make sure you call the showNavBar() method in both your onCreate() and onResume() method
public void showNavBar() {
View view = getWindow().getDecorView();
view.setSystemUiVisibility(View.VISIBLE);
}
I had the same issue, I fixed it by doing this:
In activity_main.xml add this to the CoordinatorLayout:
android:fitsSystemWindows="true"
The viewpager should be like this:
<android.support.v4.view.ViewPager
android:background="#color/colorPrimary"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
And in all your Fragments, they should start with NestedScrollView and must contain (fillViewport):
<android.support.v4.widget.NestedScrollView 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/constraintLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:context="com.khan.junaid.phonefans.MainActivity">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fans_list_view"
/>
</android.support.v4.widget.NestedScrollView>
These settings will make the fragments scrollable, and the content will no more be hiding behind the Navigation bar buttons.
