I try set padding on my ScrollView that contain LinearLayout, but i noticed that the first/last items cutting off.
Its seem like the ScrollView padding himself with the background, but don't notify a LinearLayout about that.

Thanks..
My code:
<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"
android:padding="20dp"
tools:context="com.example.aviad.scrollview.MainActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="40dp"
android:focusable="false"
android:focusableInTouchMode="false"
android:fillViewport="true"
android:background="#54d45f"
android:paddingTop="15dp"
android:paddingBottom="15dp">
<LinearLayout
android:id="#+id/conteiner"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"/>
</ScrollView>
</android.support.constraint.ConstraintLayout>
Result:
enter image description here

Just add android:clipToPadding="false" to your LinearLayout

Scroll View is not working with relative layout

I tried to make a scroll view. However,it does not display the viewPager inside the scroll view. I don't know which part is wrong.
This is my xml file
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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.qianonnphoon.tradeal.displaytrade.DisplayTradeActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="#drawable/tab_selector"
app:tabGravity="center"
app:tabIndicatorHeight="0dp">
</android.support.design.widget.TabLayout>
</android.support.v4.view.ViewPager>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="23dp"
android:layout_below="#+id/view_pager"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="#+id/tvOwnItemName"/>
</RelativeLayout>
</ScrollView>
This is the output
The viewPager is not displayed. The viewPager will be displayed only when I removed the scroll view

try this out:
<ScrollView
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical">
android:fillViewport="true" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
</RelativeLayout>
</ScrollView>

Try adding this piece of code before loading your viewPager
NestedScrollView scrollView = (NestedScrollView) findViewById
(R.id.nest_scrollview);
scrollView.setFillViewport (true);

Add
android:fillViewport="true"
to scrollview and set scrollview height to
android:layout_height="300dp"
solve my problem.
However, I dont know why the height cannot set as wrap_content

layout_weight is not working in scroll view

I am trying to use this code but its not working when i put layout weight.If i remove layout weight and enter height for image view,it works fine.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="10">
<ImageView
android:id="#+id/informative_image_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3.7"
android:scaleType="fitXY"></ImageView>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view_option_menu"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="6.3" />
</LinearLayout>
</ScrollView>

Actually you don't need scrollview. Remove it. And if you are using recyclerview inside scrollview then you need to specify height in dp of list to make it work properly.

NestedScrollView could not scroll with match_parent height child

I implement NonSwipeableViewPager with a fragment has NestedScrollView like this, what I expect is that the scrollview can scroll up and show 2 textviews:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="#layout/header" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="16dp"
android:src="#drawable/ic_up" />
</RelativeLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text 1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text 2" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
But it could not scroll, I tried many ways but still did not get any solution

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
This linearlayout should have android:layout_height="wrap_content".
Reason for that is that if the scrollview's child is the same size as the scrollview itself (both match_parent for height) it means that there is nothing to scroll through, since they are of same size and the scrollview will only be as high as the screen.
If the linearlayout has a height of wrap_content then the height is not related to the height of the screen and the scrollview will be able to scroll through it.
Just remember that a scrollview can only have 1 direct child, and that child needs android:layout_height="wrap_content"

In my case app:layout_behavior="#string/appbar_scrolling_view_behavior" this is working only if some one face problem will be try it and may be solve your problem too. you should add also android:fillViewport="true" but without this my code working.
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#drawable/subscription_background"
app:layout_behavior="#string/appbar_scrolling_view_behavior">

For me it worked when i added "android:layout_marginBottom="100dp"" for last child in androidx.core.widget.NestedScrollView

if you have used netedscrollview as follow you have to use
android:scrollbars="vertical"
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#id/toolbar_updateUserDetails"
app:layout_constraintBottom_toBottomOf="parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:scrollbars="vertical"
>
</LinearLayout>
</androidx.core.widget.NestedScrollView>

You have to calculate your other child because last child binding on nestedScrollView. You add margin like child height. It is working.

Horizontal ScrollView in fragment Android

I would like to make my ScrollView filling out the full layout of a fragment and scrolling horizontally, not vertically.
How can I achieve that?!
Like the album covers
Thanks

Its not vertically, it is horizontally
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
// Add your ImageButtons
</LinearLayout>
</HorizontalScrollView>

You have to set the scrollview to
android:fillViewport="true"
Below is the complete code
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/myscrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
</ScrollView>
