ScrollView not scrolling at all

Question

I can't make a ScrollView properly scrolling. It always cut off the content on the bottom, as if it were a normal LinearLayout.

My code

<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:id="@+id/scroll_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:isScrollContainer="true"
        android:orientation="vertical" >

Of course, I already tried to add / remove the "fillViewport" and "isScrollContainer" properties, and it did not change anything at all.

This is for ScrollView (VERTICAL ONLY)

HorizontalScrollView must be used for horizontal scrolling.

can you please paste the complete xml, maybe is something related with your LinearLayout. – Monjan

Try changing the android:layout_height="match_parent" to android:layout_height="0dp" and add android:layout_weight = "1" on the ScrollView. – Syman

Just tried and no luck. – Derwent

For users of Constraint layout, see this link – Alpinist

As @SiddharthLele suggested, setting the layout_height to 0dp did the trick for me – Contradistinction

I converted my ConstraintLayout to LinearLayout, adding margins, and I think that's what caused the problem. I just dragged a new scrollview and moved everything to it, fixing my problem. – Zither

Answer 1

Answer: the ScrollView is not working when used as the root element of an XML layout. It has to be wrapped inside a LinearLayout.

Solution then :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ScrollView android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true" >

        <LinearLayout android:id="@+id/scroll_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

        </LinearLayout>
    </ScrollView>
</LinearLayout>

Thanks! However stupid of Android this is, I wouldn't have figured out ever that this can be one of the reasons too -_- – Burberry

Also need to update the scrollView's layout_height to wrap_content – Hubris

This is not true that you cant use ScrollView as your root element, you can use ScrollView as your Root element of XML there is no problem to use it as root element. – Grande

I think this was true in 2013,but now it works on newer Android versions – Ardell

If your main view is ConstraintLayout and it has a padding - in my case was bottom padding -, scroll won't work. What I did is, I added another layout and pinned it to the main one top, bottom ,right, left and then added the scrollview as child of the second layout and pinned it again to four sides and set height to 0dp, it works – Minorca

Answer 2

❌Tried all the above mentioned answers, but still my issue was unsolved. And after some debugging and changes, my issue got fixed that is the ScrollView is getting scrolled.

• We need not to add any parent element to the ScrollView to make it scroll (as mentioned in some of the other answers here).

✔️The Fix was for my issue✔️

• changed the height of the ScrollView to 0dp

  android:layout_height="0dp"

• Constrained the Top and Bottom to parent/respective views/elements

  app:layout_constraintTop_toBottomOf="@+id/imageView4" app:layout_constraintBottom_toBottomOf="parent"

The final xml looks like this

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:layout_constraintTop_toBottomOf="@+id/imageView4"
    app:layout_constraintBottom_toBottomOf="parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

           <!-- Loong content -->

    </LinearLayout>
</ScrollView>

Scroll View as Parent has no issues. I faced such issue when we add padding/margin to the direct child of scrollview. Keep the child of scrollview with just height and width properties, den it will work fine.

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:animateLayoutChanges="true"
        android:fillViewport="true">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:animateLayoutChanges="true"
            android:orientation="vertical">
</LinearLayout>
</ScrollView>

OMG I've been struggling with this for like an hour now. This is gold. – Evocation

Worked for me as well! Thank you! – Mandamus

Answer 4

The selected answer IS NOT CORRECT!

You CAN use ScrollView as the root view, it doesnt work for you because you are missing the padding.

Add something like:

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"

Grand

How will one know how much padding will be enough? I mean since all devices are different wouldn't it cause problems? – Promethium

Answer 5

remove the android:isScrollContainer in LinearLayout. As per the documentation android:isScrollContainer is used to set the view scrollable. I hope it helps you. Refer this link for definition.

Answer 6

Android Studio adds a NestedScrollView to the activity file of some of its templates (e.g. Master-Detail). Having a ScrollView in the fragment file and another one in that fragment’s activity file prevents the scroll view from working. Removing the ScrollView in my fragment file and leaving the one in the activity file solved the issue for me.

Answer 7

Try this solution, just delay your scroll using post delayed method.

fragment_test.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootRelativeLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:fresco="http://schemas.android.com/apk/res-auto">

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="40dp"
        android:fillViewport="true"
        android:scrollbars="none">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            ...
        </RelativeLayout>

    </ScrollView>

</RelativeLayout>

TestFragment.java

...
private ScrollView mScrollView;
...
mScrollView = (ScrollView) mView.findViewById(R.id.scrollView);
mScrollView.setSmoothScrollingEnabled(true);
...
new Handler().postDelayed(new Runnable() {
    @Override
     public void run() {
         if(isAdded()) {
             // Scroll 1000px down
             mScrollView.smoothScrollTo(0, 1000);
         }
     }
}, 150);

This worked for me, hope this helps.

Try this,

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:fillViewport="true" >

<LinearLayout android:id="@+id/scroll_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

I finally figured it out took me literally 5 hours building everything step by step and testing it every step at a time ugh....

Anyway if you have a problem with this i found out that setOntouch listener is messing up your code - at least in my case it was...

i have to figure a way around it, but try to delete your ontouch listener and test your code - it has to work

This fixed my problem: I added android:isScrollContainer="true" to a LinearLayout and Removed the ScrollView Code Before:

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<ScrollView
    android:id="@+id/scrollViewRecords"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <LinearLayout
        android:id="@+id/sheepList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

    </LinearLayout>
</ScrollView>
</LinearLayout>

Code After

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:isScrollContainer="true">

    <LinearLayout
        android:id="@+id/sheepList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

    </LinearLayout>
</LinearLayout>

Answer 11

Is there a way to close this question? it is old and currently the answer marked as valid doesn't have sense. The only valid thing regarding ScrollView right now is this:

A view group that allows the view hierarchy placed within it to be scrolled. Scroll view may have only one direct child placed within it. To add multiple views within the scroll view, make the direct child you add a view group, for example LinearLayout, and place additional views within that LinearLayout. Never add a RecyclerView or ListView to a scroll view. Doing so results in poor user interface performance and a poor user experience.

Don't add any margin and padding in the layouts – Strobilaceous

The accepted answer already answers the question. Also the closing xml tag should be added - this could be mistaken as 2 layouts inside the parent layout. Also add some description to it. – Brockington

Answer 13

Looks like you're not using some of the properties and rules.

android:layout_height="0dp"
android:scrollbars="none"
android:fillViewport="true"

Also, after this try to wrap all your scrolling content in Constraint Layout.

<tech.loung.views.SlidingScrollView
android:id="@+id/scrollview_settings"
android:layout_width="match_parent"
android:layout_height="0dp"
android:scrollbars="none"
android:fillViewport="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="@+id/top_layout">

In my scenario it worked when I update Linear layout inside the scroll view with Padding=10dp. That's it scroll view Scrolled successfully

<ScrollView
    android:id="@+id/mainScrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize">


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/top_layout"
        android:orientation="vertical"
        android:layout_margin="10dp"
        android:padding="10dp">

Answer 16

Wasted an hour with this issue my findings are listed below ,hope will help someone.

1. You can have ScrollView as root tag
2. You can have ScrollView child of any other layouts.
3. You can only have single child ScrollView (I prefer LinearLayout)
4. I prefer keeping height of scroll view to 0dp
5. When your root is ConstraintLayout set layout_constraintBottom_toBottomOf="parent"
6. The child view of ScrollView should not have margin or padding.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
