I have it all set up to load a uri its basically the exact same as the example in the expo docs. I cant figure out how to use my local file system instead. I have the mp4 in my file system but when I link the path to the file system the screen goes blank and nothing shows. I'll include the snippet of code that I'm using but can't seem to get it to work
import * as React from "react";
import { View, StyleSheet, Button } from "react-native";
import { Video, AVPlaybackStatus } from "expo-av";
export default function App() {
const video = React.useRef(null);
const [status, setStatus] = React.useState({});
return (
<View style={styles.container}>
<Video
ref={video}
style={styles.video}
source={{
videoURL: require("../assets/videos/TestVideo.mp4"),
}}
useNativeControls
resizeMode="contain"
isLooping
onPlaybackStatusUpdate={(status) => setStatus(() => status)}
/>
<View style={styles.buttons}>
<Button
title={status.isPlaying ? "Pause" : "Play"}
onPress={() =>
status.isPlaying
? video.current.pauseAsync()
: video.current.playAsync()
}
/>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
video: {
flex: 1,
},
});
There is no mention of videoURL bit in the docs so just drop it and you'll see the video:
source={require("../assets/videos/TestVideo.mp4")}

I'm trying to use the last child selector remove the bottom border from the last Text tag here.
I've used both the EStyleSheet and the StyleSheet but it doesn't seem to be working – the last Text tag still has a bottom border.
I've wrapped the Text tags in View and applied the 'opt' style to the View instead and that also doesn't work.
What am I doing something wrong?
import React from 'react';
import EStyleSheet from 'react-native-extended-stylesheet';
import {
Text,
View,
Image,
} from 'react-native';
EStyleSheet.build()
const styles = EStyleSheet.create({
container:{
flex:1,
},
options:{
},
opt:{
padding:5,
fontSize:25,
borderWidth:1,
borderColor:'black',
},
'opt:last-child': {
borderBottomWidth:0,
}
});
const Settings = () => {
return <View style={styles.container}>
<View style={styles.options}>
<Text style={styles.opt}>Edit profile</Text>
<Text style={styles.opt}>Preferences</Text>
<Text style={styles.opt}>Account settings</Text>
</View>
</View>
};
export default Settings;
To accomplish an item-order aware styling, try something that makes use of EstyleSheet.child like this way:
const items = ['Edit profile', 'Preferences', 'Account settings'];
const Settings = () => (
<View style={styles.container}>
<View style={styles.options}>
{items.map((text, i) => {
const style = EStyleSheet.child(styles, 'opt', i, items.length);
return <Text style={style}>{text}</Text>;
})}
</View>
</View>
);
I am trying to change the default Mapbox pin icon on Android as in iOS I'm getting the expected result.
Issue
Not able to change PointAnnotation Icon(Using PNG format)
Callout image is also not loading(Using PNG format)
Not able to click on callout.
All the above issues I'm facing in Android only, iOS is working fine.
import React from 'react';
import {
View,
Image,
} from 'react-native';
import MapboxGL from '#react-native-mapbox-gl/maps';
const currentLatLng = [
[-74.00597, 40.71427]
];
class BugReportExample extends React.Component {
render() {
return (
View style={{flex: 1}}>
<MapboxGL.MapView
ref={c => (this._map = c)}
logoEnabled={false}
style={{flex: 1}}>
<MapboxGL.Camera
ref={c => (this.camera = c)}
zoomLevel={14}
centerCoordinate={currentLatLng}
/>
{/* User location */}
<MapboxGL.PointAnnotation
key={'9090'}
ref={ref => (this.userAnnotationRef = ref)}
id={'9090'}
coordinate={currentLatLng}
title="">
<View style={{ width: 45,height: 45,alignItems: 'center',justifyContent: 'center',overflow: 'hidden',}}>
<Image
source={{uri:'https://reactnative.dev/img/tiny_logo.png'}}
resizeMode={'contain'}
style={{height: wp('10%'), width: wp('10%')}}
onLoad={() => this.userAnnotationRef.refresh()}
/>
</View>
<MapboxGL.Callout title={'You'} />
</MapboxGL.PointAnnotation>
</MapboxGL.MapView>
</View>
);
}
}
This is working fine on iOS.
iOS Result
Android - Issue
const ImageMarker = ({ children }) =>
Platform.select({
ios: children,
android: (
<Text
style= {{
lineHeight: 60, // there is some weird gap, add 40+ pixels
// backgroundColor: '#dcdcde',
}}>
{ children }
< /Text>
),
});
<ImageMarker>
<Image
source={IMAGE_LINK}
style={{width: 45, height: 55}}

</ImageMarker>
Load image before assigning it to the PointAnnotation.
const [imagesLoaded, setImagesLoaded] = useState(false);
setTimeout(() => {
setImagesLoaded(true);
}, 500);
const Example = () => {
render() {
return (
{imagesLoaded ?
// Your mabox code with PointAnnotation
:

/>
);
}

I'm making a view in react native but my component has a webview to display HTML, below the webview is a flatlist( list of items)
The parent component is supposed to be scrollable based on the webview & the flatlist.
I tried to put them together but it doesn't work as I want.
Therefore I would appreciate all of your advice & suggestions. Thank you
Updated:
I found out a solution here after the owner of the lib has been updated
https://github.com/iou90/react-native-autoheight-webview/issues/81
You can use WebView as a header component of FlatList as this:
<View style={styles.container}>
<FlatList
data={[
{ key: 'a' },
{ key: 'b' },
{ key: 'c' },
{ key: 'd' },
]}
renderItem={({ item }) => <Text>{item.key}</Text>}
ListHeaderComponent={
<View style={{ height: 200 }}>
<WebView
originWhitelist={['*']}
source={{ html: '<h1>Hello world</h1>' }}
/>
</View>
}
/>
</View>
But there is still a limitation, you have to specify the height of the view that wraps WebView as done above.
Hope, you got the idea ?
Maybe this will help.
import React, { Component } from 'react';
import { Text, View, StyleSheet, WebView, FlatList } from 'react-native';
export default class App extends Component {
onNavigationStateChange = navState => {
if (navState.url.indexOf('https://www.google.com') === 0) {
const regex = /#access_token=(.+)/;
let accessToken = navState.url.match(regex)[1];
console.log(accessToken);
}
};
render() {
const url = 'https://api.instagram.com/oauth/authorize/?client_id={CLIENT_ID}e&redirect_uri=https://www.google.com&response_type=token';
return (
<View style={{flex: 1}}>
<WebView
source={{
uri: url,
}}
scalesPageToFit
javaScriptEnabled
style={{ flex: 1 }}
/>
<FlatList data={[1, 2, 3]} renderItem={(item) => <Text>item</Text>}/>
</View>
);
}
}
I am developing an application where I have a button (TouchableHighlight) when pressing this button it is necessary to capture a screeshot of the current screen and save the file in the device.
My code does not show error, but when I press the button (TouchableHighlight) I get the message:
Image saved to file: ///data/user/0/com.appcamerav4/cache/ReactNative-snapshot-image8525057299267209213.jpg through Remote JS Debugging .
I can not open this directory and need to save the image to the device.
I'm new to react-native.
Follow my code below:
import React, { Component } from 'react';
import { Text, View, Image, StyleSheet, TouchableHighlight, WebView, StatusBar, Button } from 'react-native';
import { captureScreen } from "react-native-view-shot";
const zooMais = require('../imgs/zooMais.png');
const zooMenos = require('../imgs/zooMenos.png');
const imgScreeshot = require('../imgs/screeshot.png');
const btnZooMais = ()=>{
alert("Zoo Mais");
console.log("Zoom +");
}
const btnZooMenos = ()=>{
alert("Zoo Menos");
console.log("Zoom +");
}
const capitureScreen = ()=>{
captureScreen({
format: "jpg",
quality: 0.8,
}).then(
uri => console.log("Image saved to", uri),
error => console.error("Oops, snapshot failed", error)
);
}
export default class Monitor extends Component {
render() {
return (
<View style={ style.viewPrincipal }>
<StatusBar hidden />
<View style={ style.viewImagem } >
<WebView
style={style.video}
automaticallyAdjustContentInsets={true}
scalesPageToFit={true}
startInLoadingState={false}
contentInset={{top: 0, right: 0, left: 0, bottom: 0}}
scrollEnabled={true}
source={{uri: 'https://facebook.github.io/react/logo-og.png'}}
onNavigationStateChange = {this.handleNavigationStateChange}
/>
</View>
<View style={ style.viewRodape }>
<View style={style.viewMenu}>
<View >
<TouchableHighlight onPress={ btnZooMais } >
<Image style={style.imgMenu} source={zooMais } />
</TouchableHighlight>
</View>
<View>
<TouchableHighlight onPress={ capitureScreen }>
<Image style={style.imgMenu} source={ imgScreeshot } />
</TouchableHighlight >
</View>
<View>
<TouchableHighlight onPress={ btnZooMenos } >
<Image style={style.imgMenu} source={ zooMenos } />
</TouchableHighlight>
</View>
</View>
</View>
</View>
);
}
}
const style = StyleSheet.create({
viewPrincipal:{
flex: 1
},
viewImagem:{
flex:10,
justifyContent:'center',
alignItems:'stretch'
},
viewRodape:{
flex:1.3
},
viewMenu:{
flexDirection:'row',
justifyContent: 'space-between'
},
imgMenu:{
margin: 0,
marginBottom:0
},
video:{
flex:1
}
});
Make sure react-native-view-shot is correctly linked in XCode (might require a manual installation,
refer to React Native doc).
import React, { useRef } from "react"; // import useRef hook on top
const cardRef = useRef(); // Use this hook inside your func. component *important
// Define a function like this
const saveAsImage = async () => {
try {
const result = await captureRef(cardRef, {
result: "tmpfile",
quality: 1,
format: "png",
});
MediaLibrary.saveToLibraryAsync(result);
} catch (e) {
console.log(e);
}
};
Apply a prop eg. parentRef={cardRef} to your component, make sure the ref name matches which in this case is "cardRef".
Give any Button/TouchableOpacity
onPress={() => {saveAsImage();}}
To solve this problem you have to go on your App permission on your real mobile and allow for camera storage then you can easily save your ViewShot on Your Mobile.
go to App Permisssion in your App.info
allow Camera accesss storage
To save the screenshot to the camera roll, use this one: https://facebook.github.io/react-native/docs/cameraroll.html#savetocameraroll
More info: https://github.com/gre/react-native-view-shot Check the FAQ section
The Error has been resolved as per your guidelines.
But still can not take and save the screeshot of the desired ViewShot, where it has a react image.
I need to take and save the screeshot in the memory of my device.
Can you tell me if I'm on the right track or would I have another way to do it? Thanks!
Follow my current code.
import React, { Component } from 'react';
import { Text, View, Image, StyleSheet, TouchableHighlight } from 'react-native';
import { captureScreen } from "react-native-view-shot";
import ViewShot from "react-native-view-shot";
const zooMais = require('../imgs/zooMais.png');
const zooMenos = require('../imgs/zooMenos.png');
const imgScreeshot = require('../imgs/screeshot.png');
const btnZooMais = ()=>{
alert("Zoo Mais");
}
const btnZooMenos = ()=>{
alert("Zoo Menos");
}
const capitureScreen = ()=>{
captureScreen({
format: "jpg",
quality: 0.9,
}).then(
uri => console.log("Image saved to", uri),
error => console.error("Oops, snapshot failed", error)
);
}
export default class Monitor extends Component {
componentDidMount () {
this.refs.viewShot.capture().then(uri => {
console.log("do something with ", uri);
});
}
render() {
return (
<View>
<ViewShot ref="viewShot" options={{ format: "jpg", quality: 0.9 }} >
<Image source={{uri: 'https://facebook.github.io/react/logo-og.png'}} style={ style.video } />
</ViewShot>
<View style={style.menu}>
<View>
<TouchableHighlight onPress={ btnZooMais } >
<Image style={style.imgMenu} source={zooMais } />
</TouchableHighlight>
</View>
<View>
<TouchableHighlight onPress={ capitureScreen }>
<Image style={style.imgMenu} source={ imgScreeshot } />
</TouchableHighlight >
</View>
<View>
<TouchableHighlight onPress={ btnZooMenos } >
<Image style={style.imgMenu} source={ zooMenos } />
</TouchableHighlight>
</View>
</View>
</View>
);
}
}
const style = StyleSheet.create({
corpo: {
},
menu:{
flexDirection:'row',
justifyContent: 'space-between'
},
imgMenu:{
//margin: 15
},
video: {
width: 400,
height: 450
}
});
Looks like you may not have either linked the package or rebuilt the app after linking.
Try
$ react-native link react-native-view-shot
$ react-native run-{ios|android}
