<p>ListView - A core component designed for efficient display of vertically scrolling lists of changing data. The minimal API is to create a <a href="listviewdatasource.md"><code>ListView.DataSource</code></a>, populate it with a simple array of data blobs, and instantiate a <code>ListView</code> component with that data source and a <code>renderRow</code> callback which takes a blob from the data array and returns a renderable component.</p>
<p>Minimal example:</p>
<pre><code class="hljs"><span class="hljs-class"><span class="hljs-keyword">class</span> <span class="hljs-title">MyComponent</span> <span class="hljs-keyword">extends</span> <span class="hljs-title">Component</span> </span>{
<span class="hljs-keyword">constructor</span>() {
<span class="hljs-keyword">super</span>();
<span class="hljs-keyword">const</span> ds = <span class="hljs-keyword">new</span> ListView.DataSource({<span class="hljs-attr">rowHasChanged</span>: <span class="hljs-function">(<span class="hljs-params">r1, r2</span>) =></span> r1 !== r2});
<span class="hljs-keyword">this</span>.state = {
<span class="hljs-attr">dataSource</span>: ds.cloneWithRows([<span class="hljs-string">'row 1'</span>, <span class="hljs-string">'row 2'</span>]),
};
}
render() {
<span class="hljs-keyword">return</span> (
<span class="xml"><span class="hljs-tag"><<span class="hljs-name">ListView</span>
<span class="hljs-attr">dataSource</span>=<span class="hljs-string">{this.state.dataSource}</span>
<span class="hljs-attr">renderRow</span>=<span class="hljs-string">{(rowData)</span> =></span> <span class="hljs-tag"><<span class="hljs-name">Text</span>></span>{rowData}<span class="hljs-tag"></<span class="hljs-name">Text</span>></span>}
/>
);
}
}
</span></code></pre>
<p>ListView also supports more advanced features, including sections with sticky section headers, header and footer support, callbacks on reaching the end of the available data (<code>onEndReached</code>) and on the set of rows that are visible in the device viewport change (<code>onChangeVisibleRows</code>), and several performance optimizations.</p>
<p>There are a few performance operations designed to make ListView scroll smoothly while dynamically loading potentially very large (or conceptually infinite) data sets:</p>
<ul>
<li><p>Only re-render changed rows - the rowHasChanged function provided to the data source tells the ListView if it needs to re-render a row because the source data has changed - see ListViewDataSource for more details.</p></li>
<li><p>Rate-limited row rendering - By default, only one row is rendered per event-loop (customizable with the <code>pageSize</code> prop). This breaks up the work into smaller chunks to reduce the chance of dropping frames while rendering rows.</p></li>
</ul>

<p>(rowData, sectionID, rowID, highlightRow) => renderable</p>
<p>Takes a data entry from the data source and its ids and should return a renderable component to be rendered as the row. By default the data is exactly what was put into the data source, but it's also possible to provide custom extractors. ListView can be notified when a row is being highlighted by calling <code>highlightRow(sectionID, rowID)</code>. This sets a boolean value of adjacentRowHighlighted in renderSeparator, allowing you to control the separators above and below the highlighted row. The highlighted state of a row can be reset by calling highlightRow(null).</p>
