We are building dynamic app and we can't know in advanced what kind of styles will user set for components, or even what components will be created as a ScrollView children or parent. I solved this by wrapping ScrollView inside View, converting width and height percentage to number logical pixels and passing it to child components:. Skip to content.

Solution : Make the wrapper fill the entire screen. I also changed your code minimally to make it useful for people who don't have your image and to better see what's happening I named the values differently. In my case the issue wasn't flex: 1 or flexGrow: 1but using padding on ScrollView styles. So if you want to add padding to your ScrollViewcreate a View inside it and apply padding to it instead.
Adding marginBottom to the scrollview 's style fixed the issue for me. We need to increase the marginBottom value until we can scroll to see the full content. Learn more. Asked 2 years, 9 months ago. Active 1 month ago.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I would like to find a way to programmatically scroll to the bottom of a scrollView. I am aware of the scrollTo method after looking at the source code for ScrollView, however I cannot seem to find a way to measure the content size of the scrollView. After looking around, I came across this github issue that mentions to look at how "UIManager. However after searching several times through the source code, I cannot quite seem to find where these methods are used.

From the data, you can get the contentsize of the scrollview whose height is the fourth element of data. Of course you can get the content offset from it. If you want to get the ScrollView's frame, you should use React.
If you want to replace According to the documentation: If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right. This event will fire once the inner child components finish laying out and upon change. This works for me and I recommend this supported approach when determining content bounds. Use a ListView to render the chat.
Add a footer to the list with renderFooter that uses onLayout to save its y position. The footer doesn't have to render anything visible, just an empty View. All you're looking for is where the bottom of the list is. Add an onLayout handler to the ListView itself that saves the lists height.

I tried what you said, however the data parameter always comes back as 0 zerorather than an object or array. Any ideas? I think I've found the source code you are talking about github.
The first parameter of measure seems to be a reactTag but I'm not entirely sure what that tag refers to. I had updated my answer. Ok thanks for that, now I am able to receive the scollView content size height, however there seems to be another problem. This happens whether I call this.
Am I doing something wrong?Component that wraps platform ScrollView while providing integration with touch locking "responder" system. Keep in mind that ScrollViews must have a bounded height in order to work, since they contain unbounded-height children into a bounded container via a scroll interaction.
In order to bound the height of a ScrollView, either set the height of the view directly discouraged or make sure all parent views have bounded height. Doesn't yet support other contained responders from blocking this scroll view from becoming the responder. ScrollView renders all its react child components at once, but this has a performance downside. Imagine you have a very long list of items you want to display, maybe several screens worth of content.
Creating JS components and native views for everything all at once, much of which may not even be shown, will contribute to slow rendering and increased memory usage.
This is where FlatList comes into play. FlatList renders items lazily, when they are about to appear, and removes items that scroll way off screen to save memory and processing time. FlatList is also handy if you want to render separators between your items, multiple columns, infinite scroll loading, or any number of other features it supports out of the box.
When true, the scroll view bounces horizontally when it reaches the end even if the content is smaller than the scroll view itself. These styles will be applied to the scroll view content container which wraps all of the child views. Handler function is passed the content width and content height as parameters: contentWidth, contentHeight.
It's implemented using onLayout handler attached to the content container which this ScrollView renders. Fires at most once per frame during scrolling. The frequency of the events can be controlled using the scrollEventThrottle prop. When true, the scroll view stops on multiples of the scroll view's size when scrolling. This can be used for horizontal pagination. The default value is false. A RefreshControl component, used to provide pull-to-refresh functionality for the ScrollView.
Only works for vertical ScrollViews horizontal prop must be false. Experimental: When true, offscreen child views whose overflow value is hidden are removed from their native backing superview when offscreen.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

When you scroll in a ScrollView and it reaches its end, it will leave a small gap below the ScrollView note the white space above the Android navigation bar.
I think it's because the bounce animation gets cut off. It only happens when you scroll inertially - if you reach the end with your finger still on the screen, it works as expected. I also tried giving the ScrollView flex: 1wrapping it in a View with flex: 1disabling removeClippedSubviews - all the "tricks" I could find in other issues, but still no go.
I expect the ScrollView to have the same bounce effect at its start and its end and to not leave any gaps behind. What's actually happening is that the ScrollView bounce effect only works at the top. At the bottom, it gets chopped off and leaves a gap behind. Here is a sample project :. If you set backgroundColor on the ScrollView directly, it solves the problem, eg:. I'm pretty sure that it wasn't an issue with v0. I'm gonna go back and test out the different versions of RN on the sample project and get back with the results.

I built a view that is populated dynamically using array mapping. After doing this, I realized that the View would be too large to contain all the array items on one screen.
This does add some scrollability to the view, but it's still cutting off a portion of the last object in the array. ScrollView is intended for showing scrollable content at once. Since you are populating content dynamically, you should be using FlatList. Something similar to the following would work:. Detailed explanation is available in the docs. If you are by any reason still forced to stick to Scrollviewthe problem is probably related to the styling. I suppose styles. Learn more. ScrollView cuts off last object on the page Ask Question.

It could be that you need to add flex: 1, or if there's a component below it, it might be due to the styling of that component overlapping the scrollview.

The docs make it sound as if only the height of the ScrollView itself needs to be set in order to function. I could be implementing it wrong but rendering a plain ScrollView with a set height that's not nested produces a ScrollView that bounces but does not scroll. Experiencing the same thing. This sure seems like a bug to me, but if it's not the docs should definitely reflect that you need to nest it in another View and can't set height on the ScrollView directly.
After you see the full screen ScrollView, just wrap the ScrollView in an unstyled view to see it display at the correct height. Neither my profile component or the dashboard component is scrolling.
Even when i cut and paste the code from Branch 13 in this egghead. This is the component code which works for rendering the data but does not scroll the data. Anything stand out here? How is this not trivial? I only get a working scrollView with fixed height so far no specific scrollview wrapper neededsetting flex:1 on contentContainerStyle, style or wrapper style, setting it on any or all of them does not work for me.
It just renders the entire view, overflowing the screen, no scroll. In my case, there was another flex element above the scroll view that made things weird. The component that holds that dynamic content is resizing correctly, but it's as though the parent isn't taking that height change into account and I can't scroll to the bottom of our list. Do I need to do something with onLayout to notify that parent ScrollView of the height change?
Thanks ospfranco I got it working. I ended up with a static height on something that was causing the issue. Totally my fault :s.React Native ScrollView example + ScrollView Infinite Scroll
Takes the full height and goes deep down the screen. But with this solution you cannot really rely on "flex" in direct children. If the screen isn't initially filled with content you'll have some unused spaces. I tried to set up a bounded height scrollview, but it seems like to automatically take up all remaining height of parent, the only way to do it for me is to use a wrapper view outside of scrollview.
I also experience the same thing. Except that scrolling to bottom would not be actual bottom, I would have content cut off. Setting flexGrow:1 on the view did not fix it for me. I would get this content cut off bug when adding a marginVertical to the ScrollView or FlastList too. In my case also the scrollview doesnot scrolls inside a view conmponent. Any solutions for it?
Just ran into this. I wanted a horizontal ScrollView to take as little height as possible. The ScrollView by itself displayed as if it had flex: 1 specified, which it didn't.
