All props are passed through to the underlying ListViewso you can specify all the available props for ListView normally - except the following, which are defined internally and will be overwritten:.

Note: If the data your are providing to the component is an array, the section list will automatically be hidden. Is required if a header element is used, so the positions can be calculated correctly. Defaults to false This is an experimental feature.

For it to work properly you will most likely have to experiment with different values for scrollRenderAheadDistancedepending on the size of your data set. These props are automatically passed to your component. In addition to these, your cell will receive all props which you specified in the object you passed as cellProps prop to the listview.

I fixed some issues with the scrolling not working correctly and exposed the main listview component as AtoZList. The scroll performance is great for large lists which is why I switched to using brentvatne's implementation.

This package provides an alphabetical scrolling capable FlatList. It supports thousands of items and runs smoothly on phones.

It works the same as native FlatList works, has the same props, and we add a vertical sidebar where the user can slide to quickly navigate the list by letter.

Check out the example page and the the example page source for examples of different configurations. A function that receives an index and a key and returns the content to be rendered for the item at that index. A function that receives the rendered items and a ref. A function that receives an item index and the cached known item sizes and returns an estimated size height for y-axis lists and width for x-axis lists of that item at that index.

This prop is only used when the prop type is set to variable and itemSizeGetter is not defined. Use this property when you can't know the exact size of an item before rendering it, but want it to take up space in the list regardless. A function that receives an item index and returns the size height for y-axis lists and width for x-axis lists of that item at that index.

This prop is only used when the prop type is set to variable. The minimum number of items to render at any given time. This can be used to render some amount of items initially when rendering HTML on the server.

The number of items to batch up for new renders. Does not apply to 'uniform' lists as the optimal number of items is calculated automatically.

A function that returns a DOM Element or Window that will be treated as the scrolling container for the list. In most cases this does not need to be set for the list to work as intended.

It is exposed as a prop for more complicated uses where the scrolling container may not initially have an overflow property that enables scrolling.

A function that returns the size of the scrollParent's viewport. Provide this prop if you can efficiently determine your scrollParent's viewport size as it can improve performance. It will not cache item sizes or remove items that are above the viewport. This type is sufficient for many cases when the only requirement is incremental rendering when scrolling. Supply the itemSizeGetter when possible so the entire length of the list can be established beforehand.

Otherwise, the item sizes will be cached as they are rendered so that items that are above the viewport can be removed as the list is scrolled. The advantage here is that the size of the entire list can be calculated ahead of time and only enough items to fill the viewport ever need to be drawn. The size of the first item will be used to infer the size of every other item. Multiple items per row are also supported with this type.

Set to true if the item size will never change as a result of responsive layout changing or otherwise.

Oct 22, 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.

When true, the scroll view bounces vertically when it reaches the end even if the content is smaller than the scroll view itself. The default value is true. When true, the scroll view bounces when it reaches the end of the content if the content is larger then the scroll view along the axis of the scroll direction. When false, once tracking starts, won't try to drag if the touch moves. When true, the scroll view automatically centers the content when the content is smaller than the scroll view bounds; when the content is larger than the scroll view, this property has no effect.

The default value is false. These styles will be applied to the scroll view content container which wraps all of the child views. The amount by which the scroll view content is inset from the edges of the scroll view.

This property specifies how the safe area insets are used to modify the content area of the scroll view. The default value of this property is "never". Available on iOS 11 and later. A floating-point number that determines how quickly the scroll view decelerates after the user lifts their finger.

When true, the ScrollView will try to lock to only vertical or horizontal scrolling while dragging. When true, the scroll view stops on the next index in relation to scroll position at release regardless of how fast the gesture is. This can be used for horizontal pagination when the page is less than the width of the ScrollView. When true, the default JS pan responder on the ScrollView is disabled, and full control over touches inside the ScrollView is left to its child components.

This is particularly useful if snapToInterval is enabled, since it does not follow typical touch patterns. Do not use this on regular ScrollView use cases without snapToInterval as it may cause unexpected touches to occur while scrolling. Sometimes a scrollview takes up more space than its content fills. When this is the case, this prop will fill the rest of the scrollview with a color to avoid setting a background and creating unnecessary overdraw.

This is an advanced optimization that is not needed in the general case. If the value is greater than 0, the fading edges will be set accordingly to the current scroll direction and position, indicating if there is more content to show. When true, the scroll view's children are arranged horizontally in a row instead of vertically in a column.

If sticky headers should stick at the bottom instead of the top of the ScrollView. This is usually used with inverted ScrollViews.

When set, the scroll view will adjust the scroll position so that the first child that is currently visible and at or beyond minIndexForVisible will not change position.React Native provides a suite of components for presenting lists of data. Generally, you'll want to use either FlatList or SectionList. The FlatList component displays a scrolling list of changing, but similarly structured, data. FlatList works well for long lists of data, where the number of items might change over time.

Unlike the more generic ScrollViewthe FlatList only renders elements that are currently showing on the screen, not all the elements at once. The FlatList component requires two props: data and renderItem.

SectionList

This example creates a basic FlatList of hardcoded data. Each item in the data props is rendered as a Text component. If you want to render a set of data broken into logical sections, maybe with section headers, similar to UITableView s on iOS, then a SectionList is the way to go.

One of the most common uses for a list view is displaying data that you fetch from a server. To do that, you will need to learn about networking in React Native.
