Hi and welcome to our tutorial on the view component in React native
for beginners. React native provides a set of core components that can be used
to create the layout and behavior of your app.
In this video we'll be discussing the view component and providing examples of how it
is used in React native to create a layout and why it is important
component. The view component in React
native is a fundamental building block for creating layout of React native app.
It works similarly to the div element
in web development in that it can be used as a container for other components
and can be used to apply styles to the layout.
The view component can be used to create
different types of layouts such as a grid or a stack.
For example, you can use multiple view components to create a grid of items or
you can use a single view component to create a stack of items.
The view component can also be used
to create a responsive design which is important for ensuring that your app look
good on different devices and screen sizes.
We're going to discuss this topic more once we dive into Flexbox
layout for React native.
In React native the layout of an app is
defined using a tree like structure of components where the view component
acts as the container for other components.
This allows you to create nested structure
of components where each component defines a specific part of the layout.
The view component can also be used
to apply styles to the layout using the style prop.
This allows you to easily control the layout and appearance of your app.
Now I quickly want to demonstrate the use of view component in React native.
Now you're looking at my screen where I have my simulator open,
I have my metro running and you see my editor here and in my editor we're
exactly at the point where we left off the last time.
Now what I want to do is divide our screen
into different layouts because that's one of the main uses of the view component.
So let's say that we want our app
to contain a header, we want our app to have the main body
section and then we want it to have the footer.
What we're going to be doing for this is
we're going to be creating the containers using the view component.
So let's first import the view component here and then let's use this view
component to say that this is going to be our header.
Now if we were to save this,
you're going to see that nothing is changing in our simulator.
We still are going to have our green text displayed exactly as we did before
and the view component is not going to take any space.
However, if we were to use this view
component to say that this is our header, we could just put in a text here saying
that this is going to be our header container.
Okay, now we're going to get error because I haven't imported the text.
So this is going to be our header container.
Now what we want to do is also create
a body container where our main content is going to go.
We can just create this view component
here and pretend that the text that we have here, hello, react native world is
the thing that we want to have in our body.
And now we're going to have a container
for our main content which is going to be this.
We can also copy and paste this component multiple styles, which is going to be one
of the main benefits of reusability that our components offer us.
And you're going to see multiple text appear here.
And we can also create another view
component that's going to have a text as well inside it
and we're going to say that this is going to be our footer saying that all rights
reserved. You have an ability to apply styles to these views as well.
We could create a style and say that we
want the background color for this to be blue.
Now you're going to see that our header is blue.
You can also give it some height,
let's say 100, and this is how much space is going to take.
You can do the same to these view containers here.
For example, if we were to say that we want our background color here to be gray,
we'll be seeing the gray background for our container.
That's it for our tutorial.
On the view component in react native, you should now have a basic understanding
of what the view component is, how it is used to create a layout,
and why it is an important component for react native.
Remember that the view component is a fundamental building block and it can be
used to create a consistent and responsive layout for your app.
