Is there any way to blur a background in react-native without using any external library.
for example, the below code blurs in web versions,
div {
background-color: rgba(28, 28, 28, 0.8);
backdrop-filter: blur(14px);
}
I tried using blurRadius and backdropfilter to but none works.
if I understood correctly, I think you can use View has low opactiy
<View style={{height:200, width:200 ,opacity:0.5,backgroundColor:'gray'}}>
<Text>Blur</Text>
</View>
Or you can use ImageBackground
<ImageBackground
source={require('YOUR_BACKGROUND_IMAGE')}
blurRadius={90}>
....
</ImageBackground>

I'm trying to render an Image as background, but is not working, I don't know why. Here is my code.

resizeMode="cover"
style={styles.style}>
</ImageBackground>
React Native does not directly support using SVG format images. In order to use SVG Images you must use 3rd party libraries. I suggest using react-native-svg. Which is a great library and here is a tutorial you can use to set it up.
Your use case is to set it as a background image. It would be better to use png or jpg formats for use with Image Background component in react native. If you only have svg format of the image, then you can set it in View and control the view
You should use react-native-svg to display SVGs.
if you want a svg in background you can do this example below
import { View, Text, Dimensions } from 'react-native'
import React from 'react'
import AFCIcon from '../assets/images/logos/AFC.svg'
const SCREEN = Dimensions.get("screen");
const App = () => {
return (
<View style={{ flex: 1 }}>
<View style={{
position: "absolute",
width: "100%",
height: "100%",
bottom: 0,
zIndex: -1,
}}>
<AFCIcon width={SCREEN.width} height={SCREEN.height} />
</View>
{/* your code here */}
</View>
)
}
export default App
I implemented a bottom half modal view in react native, which is sliding in from the bottom . I set the background of the modal view to transparent so the previous view is still visible, but the modal view is in focus. This is working fine and once it is open it also looks how I want it to look. My problem is, that the transparent background is also sliding in from the background and this does not look like a native implementation at all. What I want to achieve is, that the transparent background just appears while the modal view slides in from the bottom. Any idea on how to solve this?
Note: Iam using Modal from inbuilt react native, hence not using any npm module or package.
My code:
import { View, Text, Modal } from 'react-native';
function DurationModal(props) {
<View>
<Modal
visible={props.isVisible}
transparent
animationType='slide'
statusBarTranslucent
>
<View>
<View style={{ backgroundColor: 'rgba(0,0,0,0.1)', height: hp('60%') }}></View>
<View style={{ backgroundColor: Colors.whiteBackgroundColor, height: hp('40%') }}>
<Text>Hello</Text>
</View>
</View>
</Modal>
</View>
);
}
I have a problem with ScrollView in React-Natives. I've already looked for it in the react-native docs, but still unable to find it. Because of this I need to include an image since I don't even know how to call it.
Is it possible to change the "purple" color in this picture? How? And what is this "purple" thing called?
Here's my code to give a clue.
The ScrollView:
<ScrollView
horizontal={true}
showsHorizontalScrollIndicator={false}
style={style.scrollContainer}
endFillColor="#000"
>
The styles
scrollContainer: {
marginTop: 20,
marginHorizontal: 10,
color: "#fff",
},
Thank you
This is the overScroll glow effect on android devices and can be disabled using the overScrollMode prop. You need to set it to never as follows.
<ScrollView
horizontal={true}
showsHorizontalScrollIndicator={false}
style={style.scrollContainer}
endFillColor="#000"
overScrollMode="never"
>
I have created a little snack that showcases this prop. Notice that I have disabled this for the horizontal scrollview and enabled it for the vertical scrollview.
Changing the color is only possible by adding <item name="android:colorEdgeEffect">#E53644</item> to your styles.xml as discussed here, whereby #E53644 is the hexcode of the color of choice.
I have problems with the transparency of a View in React Native Expo, within the View I have text but this is not seen on iphone devices and on androids the text is seen with transparency but it is not what I want.
Code:
<View style= {{paddingHorizontal:30, borderRadius:1, marginTop:5}}>
<View style={{alpha = 1.0, alignItems:'center', borderRadius:10, backgroundColor: 'white', alignContent:'center', paddingVertical:10}}>
<Text style={{fontSize:15, color:'white', fontWeight: 'bold'}}>Iniciar SesiĆ³n</Text>
</View>
</View>
What I want to do:
enter image description here
What i get:
enter image description here
The alpha on the style is applied to the entire view and as a result also causes the all child components to become transparent. You want to apply your alpha only to the background color of the parent view. In react-native you can achieve that by defining your backgroundcolor rgba format
Color documentation can be found
https://reactnative.dev/docs/colors
And here is an expo snack to demonstrate the behavior.

I'm trying to use the KeyboardAvoidingView component from react native.
I want to display a little dot at the bottom of my screen. that dot is an absolut positioned element. When the keyboard appear, it hide it. I would like to know how to use that KeyboardAvoidingView component in my case :
<NetworkContext.Provider value={network}>
{props.children}
<KeyboardAvoidingView behavior={Platform.select({android: undefined, ios: "padding"})}>
{!network && <ConnectionAlert
style={{
position: "absolute",
bottom: 10,
right: 10
}}/>}
</KeyboardAvoidingView>
</NetworkContext.Provider>
There is something I did wrong ?
