Adding justifyContent to a component's style determines the distribution of children along the primary axis. Should children be distributed at the start, the center, the end, or spaced evenly? Available options are flex-start, center, flex-end, space-around, and space-between.

Adding alignItems to a component's style determines the alignment of children along the secondary axis (if the primary axis is row, then the secondary is column, and vice versa). Should children be aligned at the start, the center, the end, or stretched to fill? Available options are flex-start, center, flex-end, and stretch.
For stretch to have an effect, children must not have a fixed dimension along the secondary axis. In the following example, setting alignItems: stretch does nothing until the width: 50 is removed from the children.

The ListView component displays a vertically scrolling list of changing, but similarly structured, data.
ListView works well for long lists of data, where the number of items might change over time. Unlike the more generic ScrollView, the ListView only renders elements that are currently showing on the screen, not all the elements at once.
The ListView component requires two props: dataSource and renderRow. dataSource is the source of information for the list. renderRow takes one item from the source and returns a formatted component to render.
This example creates a simple ListView of hardcoded data. It first initializes the dataSource that will be used to populate the ListView. Each item in the dataSource is then rendered as a Text component. Finally it renders the ListView and all Text components.
A rowHasChanged function is required to use ListView. Here we just say a row has changed if the row we are on is not the same as the previous row.

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