React Native - Justify Content not Working

Asked 2021-Jun-15 at 21:59

I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:

https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js

Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the "alignItems: center" style property. I would expect that I could also center them vertically within their spaces by setting "justifyContent: center", but that doesn't seem to work for me.

Am I fundamentally misunderstanding something?

...

ANSWER

Answered 2021-Jun-15 at 21:59

The problem is that you are not aligning the text within the individual Views. Your example mistakenly aligns the inner View elements within the larger View element rather than aligning the text.

To center-align the text vertically within their Views you just need to add justifyContent: "center" to those individual three green Views.

Here's an example: https://codesandbox.io/s/recursing-kirch-n8one?file=/src/App.js:393-417

To further explain why you were experiencing the issue you did, see this screenshot with boxes outlining the space the elements were taking up on-screen:

You can see the inner Views are only taking up the needed width of the text elements inside, but are using the max height available to them.

QUESTION

Align item to full parent's width minus margin

Asked 2021-Jun-15 at 16:01

How can I stretch my subview across 100% width of its parent, minus 20px margin on each side? In other words, I need it to fill the width of the parent, with 20px open on each side.

I know in React-Native I can use width: '80%' to make my subview's width relative to that of its parent, but then it's not always precisely 20px on the sides. I also know that I can use alignSelf: 'stretch', however that is not working for me - it has unexpected / unreliable results. I don't want to use Dimensions, as the parent will not always be the device's screen, so Dimensions.get('window').width is inadequate for this problem.

What other options do I have?

Solution 1

Make Sure "http://" is in your URL Address .

change from localhost to your ip
add http://

http://192.168.43.49:3000/user/

Solution 2

I faced same issue, it happens in Android, but works well in IOS. I guess this issue about Flipper Network.

For while, I commented

initializeFlipper(this, getReactNativeHost().getReactInstanceManager())

in this file /android/app/src/main/java/com/{your_project}/MainApplication.java

Solution 3

Whoever is still struggling with this issue. it's happening because of Flipper network plugin. I disabled it and things work just fine.

My workaround to make this work is commenting out line number 43

QUESTION

If statement with props react native

Asked 2021-Jun-15 at 09:10

For a project for my study I am working on a React Native project, but I am stuck. I want to give the prop 'Score' to Card.js and based on that score a color has to be defined; 'transparancyColor'. Currently, the props are passed from Home.js to Card.js and the transparencyColor is defined there. Is this a smart way, or do I have to do this at Home.js? And how?

The code of Card.js looks as follows:

Regarding the code structure question, it's fine, especially initially, to pass props down one or two levels.

In terms of code, something like that (note the convention is to start variable names with lowercase):

Check the render method of `ExpoRootComponent`

Asked 2021-Jun-15 at 04:13

I'm trying to use react-native navigation. I installed the app, everything went alright. Now I'm having this problem with Expo when I try and create a navigation in both ios and web:

Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of ExpoRoot.

You called the API in componentWillMount() which is only triggered just before mounting occurs. To reuse the fetch API, make it a method and call it where necessary.

ANSWER

Answered 2021-Jan-28 at 10:26

On an Android 11 device your app has access to the folder you mention but it will not see files that belong to other apps. Only subfolders.

So the owner of the file is important on an Android 11 device.

For testing at home you can request all files access with MANAGE_EXTERNAL_STORAGE.
