I have used this code and its working.
But I want to do the same process by saving the page in different .js file
and navigate using navigator.
Please add sample code I am new to React Native...
var React = require('react-native');
var {
AppRegistry,
StyleSheet,
Text,
View,
Navigator,
TouchableOpacity,
} = React;
var SCREEN_WIDTH = require('Dimensions').get('window').width;
var BaseConfig = Navigator.SceneConfigs.FloatFromRight;
var CustomLeftToRightGesture = Object.assign({}, BaseConfig.gestures.pop, {
// Make it snap back really quickly after canceling pop
snapVelocity: 8,
// Make it so we can drag anywhere on the screen
edgeHitWidth: SCREEN_WIDTH,
});
var CustomSceneConfig = Object.assign({}, BaseConfig, {
// A very tighly wound spring will make this transition fast
springTension: 100,
springFriction: 1,
// Use our custom gesture defined above
gestures: {
pop: CustomLeftToRightGesture,
}
});
var PageOne = React.createClass({
_handlePress() {
this.props.navigator.push({id: 2,});
},
render() {
return (
<View style={[styles.container, {backgroundColor: 'green'}]}>
<Text style={styles.welcome}>Greetings!</Text>
<TouchableOpacity onPress={this._handlePress}>
<View style={{paddingVertical: 10, paddingHorizontal: 20, backgroundColor: 'black'}}>
<Text style={styles.welcome}>Go to page two</Text>
</View>
</TouchableOpacity>
</View>
)
},
});
var PageTwo = React.createClass({
_handlePress() {
this.props.navigator.pop();
},
render() {
return (
<View style={[styles.container, {backgroundColor: 'purple'}]}>
<Text style={styles.welcome}>This is page two!</Text>
<TouchableOpacity onPress={this._handlePress}>
<View style={{paddingVertical: 10, paddingHorizontal: 20, backgroundColor: 'black'}}>
<Text style={styles.welcome}>Go back</Text>
</View>
</TouchableOpacity>
</View>
)
},
});
var SampleApp = React.createClass({
_renderScene(route, navigator) {
if (route.id === 1) {
return <PageOne navigator={navigator} />
} else if (route.id === 2) {
return <PageTwo navigator={navigator} />
}
},
_configureScene(route) {
return CustomSceneConfig;
},
render() {
return (
<Navigator
initialRoute={{id: 1, }}
renderScene={this._renderScene}
configureScene={this._configureScene} />
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
color: 'white',
},
});
AppRegistry.registerComponent('SampleApp', () => SampleApp);
module.exports = SampleApp;
To navigate between pages, you will need 3 component (react class). One for the navigator (SampleApp here), one for pageOne and one for pageTwo. It is recommended to have one component per js file. So you need to create a file named PageOne.js, PageTwo.js and SampleApp.js. When you want to render a component stored in another file, you need to import it like this import PageOne from './path/PageOne'; The only way to access a variable from another file is by importing it, but it won't work if you don't export the variable first. Exporting a variable is basically saying to react that this block of code can be used in another file. You can export multiple variables from a file. Here is some additional info to help you understand the concept of import/export:
Import
Export
Video
Your code is perfectly fine like this. Here's what each file may look like.
SampleApp.js
var React = require('react-native');
import PageOne from './PageOne';
import PageTwo from './PageTwo';
var {
AppRegistry,
StyleSheet,
Text,
View,
Navigator,
TouchableOpacity
} = React;
var SCREEN_WIDTH = require('Dimensions').get('window').width;
var BaseConfig = Navigator.SceneConfigs.FloatFromRight;
var CustomLeftToRightGesture =
Object.assign(
{},
BaseConfig.gestures.pop,
{ snapVelocity: 8, edgeHitWidth: SCREEN_WIDTH }
);
var CustomSceneConfig = Object.assign({}, BaseConfig, {
springTension: 100,
springFriction: 1,
gestures: { pop: CustomLeftToRightGesture }
});
var SampleApp = React.createClass({
_renderScene(route, navigator) {
if (route.id === 1) {
return <PageOne navigator={navigator} />
} else if (route.id === 2) {
return <PageTwo navigator={navigator} />
}
},
_configureScene(route) {
return CustomSceneConfig;
},
render() {
return (
<Navigator
initialRoute={{id: 1, }}
renderScene={this._renderScene}
configureScene={this._configureScene} />
);
}
});
AppRegistry.registerComponent('SampleApp', () => SampleApp);
module.exports = SampleApp;
PageOne.js
var PageOne = React.createClass({
_handlePress() {
this.props.navigator.push({id: 2,});
},
render() {
return (
<View style={[styles.container, {backgroundColor: 'green'}]}>
<Text style={styles.welcome}>Greetings!</Text>
<TouchableOpacity onPress={this._handlePress}>
<View style={{paddingVertical: 10, paddingHorizontal: 20,
backgroundColor: 'black'}}>
<Text style={styles.welcome}>Go to page two</Text>
</View>
</TouchableOpacity>
</View>
)
},
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
color: 'white',
},
});
// This is important because without exporting PageOne,
// you cannot import it in SampleApp.js
export default PageOne;
PageTwo.js
var PageTwo = React.createClass({
_handlePress() {
this.props.navigator.pop();
},
render() {
return (
<View style={[styles.container, {backgroundColor: 'purple'}]}>
<Text style={styles.welcome}>This is page two!</Text>
<TouchableOpacity onPress={this._handlePress}>
<View style={{paddingVertical: 10, paddingHorizontal: 20, backgroundColor: 'black'}}>
<Text style={styles.welcome}>Go back</Text>
</View>
</TouchableOpacity>
</View>
)
},
});
var styles = StyleSheet.create({
container: {

alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {

},
});
export default PageTwo;

I am creating an application for android and ios in react-native(0.57.7) and using react-native-video to play videos uploaded into vimeo. After integrate react video plugin, tested in both device. In ios it works perfectly but in android, I am not able to play video in full-screen mode. Here is my code for Android:

and this is the output screen where I can not play video in full screen:
Please help, What I'm doing wrong ?
I have solved fullscreen of video frame just adding resizeMode on Video component:
<Video source={{ uri:this.state.videoFileArr[0].link}} // Can be a URL or a local file.
ref={ ref =>
this.player = ref
} // Store reference
onBuffer={this.onBuffer} // Callback when remote video is buffering
onError={this.videoError} // Callback when video cannot be loaded
style={styles.backgroundVideo}
controls={true}
paused={false}
fullscreen={true}
resizeMode="cover"
/>
I was struggling with the same problem couple of days ago but I made it work for me in android. I hope this will help you also.
You will need to install some other package as well that is
1. react-native-video-controls
2. react-native-orientation
now In your Screen where the video will be played.

Most of suggestion involves adding additional libraries to achieve fullscreen in react-native-vide for android. Its not really needed.
What we need is set the height and width of to full screen to achieve this. we need to use variable instead of fixed value then setState to refresh the view.
Below is the sample typescript code that works for react-native-video fullscreen:
import React, {Component} from 'react';
import {
View,
StyleSheet,
TouchableWithoutFeedback,
Dimensions,
} from 'react-native';
import Video from 'react-native-video';
import Icon from 'react-native-vector-icons/FontAwesome';
import MaterialIcon from 'react-native-vector-icons/MaterialCommunityIcons';
interface Props {}
interface States {
paused: boolean;
inFullScreen: boolean;
}
export default class Sandbox extends Component<Props, States> {
player: any;
videoStyle: {minWidth: number; minHeight: number};
constructor(props: Props) {
super(props);
this.state = {
paused: true,
inFullScreen: false,
};
this.videoStyle = {minWidth: 400, minHeight: 400};
}
render() {
return (
<View style={{height: 400, width: 400}}>
<Video
source={{
uri:
'https://www.radiantmediaplayer.com/media/big-buck-bunny-360p.mp4',
}} // Can be a URL or a local file.
ref={(ref: any) => {
this.player = ref;
}} // Store reference
controls={false}
paused={this.state.paused}
resizeMode={'cover'}
style={this.videoStyle}
/>
<View style={styles.controls}>
<TouchableWithoutFeedback
onPress={() => {
this.setState({paused: !this.state.paused});
}}>
<Icon name={'play'} size={30} color="#FFF" />
</TouchableWithoutFeedback>
<TouchableWithoutFeedback
onPress={() => {
if (!this.state.inFullScreen) {
//Orientation.lockToLandscape();
this.videoStyle = {
minHeight: Dimensions.get('window').height,
minWidth: Dimensions.get('window').width,
};
} else {
this.videoStyle = {
minHeight: 400,
minWidth: 400,
};
}
this.setState({inFullScreen: !this.state.inFullScreen});
}}>
<MaterialIcon name={'fullscreen'} size={30} color="#FFF" />
</TouchableWithoutFeedback>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
controls: {
backgroundColor: 'rgba(0, 0, 0, 0.5)',
height: 48,
top: 20,
left: 0,
bottom: 0,
right: 0,
position: 'absolute',
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'space-around',
paddingHorizontal: 10,
},
});
As #Selva answered we can use variables for video sizes i.e width & height and make it occupy full screen and use a stack to place the video in a stack screen above the current screen and pop it when needed. Even if it's in a flat list.
Had same issue fix it by removing the wrapping and setting just the height to the player, no other library needed and no need to manage the orientation.
<Video source={{uri: this.props.videoData.uri}}
onEnd={this.onVideoEnd}
style={styles.player}
controls={true} />
<View
onStartShouldSetResponder={() => setPaused(!paused)}
style={{
marginHorizontal: 10,
backgroundColor: "black",
position: "relative",
transform: [{ rotate: "90deg" }],
// justifyContent:'center',
// alignItems:'center'
}}
>
<Video
onEnd={onEnd}
onLoad={onLoad}
onLoadStart={onLoadStart}
posterResizeMode={"cover"}
onProgress={onProgress}
paused={paused}
ref={(ref) => (videoPlayer.current = ref)}
resizeMode={'stretch'}
source={{
uri: "url",
}}
style={{
...styles.backgroundVideo,
height: width,
aspectRatio:2
// width: "100%"
// alignSelf:'center'
// transform: [{ rotate: '90deg'}]
}}
/>
just give it a width of
width:'100%'
This may be dumb question but as a beginner am struggling with this don't know where am making mistake when am trying to fetch jsonarray value from api am getting Requested keys of a value that is not an object don't know where am making mistake now let me post what i have tried so far
this is the index.android code

Getting requested keys of a value that is not an object can anyone help me am struggling with this. Thanks in advance!!
I am learning react-native programming where I have one component in index.android.js. I have a TouchableOpacity in that component. I want to start next component on click on TouchableOpacity.
<TouchableOpacity style={{ height: 40, marginTop: 10 , backgroundColor: '#2E8B57'}} onPress={}>
<Text style={{color: 'white', textAlign: 'center', marginTop: 10, fontWeight: 'bold'}}>LOGIN</Text>
</TouchableOpacity>
Can anyone suggest that How can I set click listener in onPress and how to start next component on clicking on this.
Thanks in advance.
Try like this
'use strict';
var React = require('react-native');
var {
AppRegistry,
StyleSheet,
Text,

The entire point of touchable opacity is to touch it.
Put your Business Logic in a seperate class and call it from the Touchable opacity event. Then use that logic in your code where ever you want!
You can do conditional rendering in a single component depending on state/props, so maybe something like this:
render() {
return state.displayComponent?
<NewComponent /> :
<TouchableOpacity ... onPress={() => this.setState({displayComponent: true})} />
}
, but if you're looking for something more robust, read up on react-native-router-flux
I have this screen in react native
import React, { Component } from 'react';
import { AppRegistry,TouchableOpacity, Text ,Button,Image,TextInput,PropTypes,StyleSheet,View,NavigatorIOS,TouchableHighlight} from 'react-native';
class LoginView extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.title}>
HYGEX
</Text>
<View>
<TextInput
placeholder="Username"
style={styles.formInput}
/>
<TextInput
placeholder="Password"
secureTextEntry={true}
style={styles.formInput1}
/>
<TouchableHighlight style={styles.button}
onPress={() => this.move()}>
<Text style={styles.buttonText}>Login</Text>
</TouchableHighlight>
</View>
</View>
);
}
move() {
//what i can do here to go to Socrce screen ???
}
}
Something like login screen, now when I click into TouchableHighlight
I need to open this screen
'use strict';
import React, { Component } from 'react';
import { AppRegistry, ListView, Text, View } from 'react-native';
class HygexListView extends Component {
constructor(props) {
super(props);
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
this.state = {
dataSource: ds.cloneWithRows([
'John', 'Joel', 'James', 'Jimmy', 'Jackson', 'Jillian', 'Julie', 'Devin'
])
};
}
render() {
return (
<View style={{flex: 1, paddingTop: 22}}>
<ListView
dataSource={this.state.dataSource}
renderRow={(rowData) => <Text>{rowData}</Text>}
/>
</View>
);
}
}
module.exports = HygexListView;
I tried to implement move method but I failed! Any idea why?
Does react-native have a method to change the screen when click into TouchableHighlight?
As others pointed out, you have to use an instance of Navigator to transition between screens. Maybe you can have a look at the example apps in the React Native repo. I also find this router package quite easy to set up, and it also includes an example app that you can use as a starting point.
Edit
As a simple example using react-native-router-flux, you can edit the Example.js file in the Example directory to look like this:
import React, {
Component,
} from 'react';
import {
StyleSheet,
Text,
View,
} from 'react-native';
import LoginView from './LoginView';
import HygexListView from './HygexListView';
import {
Scene,
Router,
Actions,
} from 'react-native-router-flux';
const styles = StyleSheet.create({
container: { flex: 1, backgroundColor: 'transparent', justifyContent: 'center',
alignItems: 'center',
},
tabBarStyle: {
backgroundColor: '#eee',
},
tabBarSelectedItemStyle: {
backgroundColor: '#ddd',
},
});
// define this based on the styles/dimensions you use
const getSceneStyle = (/* NavigationSceneRendererProps */ props, computedProps) => {
const style = {
flex: 1,
backgroundColor: '#fff',
shadowColor: null,
shadowOffset: null,
shadowOpacity: null,
shadowRadius: null,
};
if (computedProps.isActive) {
style.marginTop = computedProps.hideNavBar ? 0 : 64;
style.marginBottom = computedProps.hideTabBar ? 0 : 50;
}
return style;
};
class Example extends Component {
render() {
return (
<Router getSceneStyle={getSceneStyle}>
<Scene key="login" component={LoginView} initial={true}/>
<Scene key="hygex" component={HygexListView } />
</Router>
);
}
}
export default Example;
Then, in your component's move function, you have to do the following:
move(){
Actions.hygex(); // This will perform a slide transition, but you can customize it. Have a look at the docs for that.
I have not tested the code, so there might be some typos/missing imports/code, but it should give you an idea of what you have to do.
}
You have to implement a Navigator, which is roughly a component that manages all stuff related to screens, and header bar with back button and etc.
As you are a beginner, I suggest you to look at the docs on this link:
https://facebook.github.io/react-native/docs/navigator.html
Sorry for the short answer, I'm on my phone.
Good luck!

You have to use navigator. please read the documentation as mentioned below. and if you will need then i will share you my code.
Here is an example: NavigatorExample
Hi everyone,
I am new to Android development using react-native and I got this error which I have no idea where this come from because I am not using ScrollView at all!
I am trying to render a list on the initial screen and its data is coming from an api call.
My code is
import React, { Component } from 'react';
import {
Image,
ListView,
TouchableHighlight,
Text,
View,
StyleSheet
} from 'react-native';
import Api from '../../Utils/api';
import CategoryRow from './CategoryRow';
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 12,
flexDirection: 'row',
alignItems: 'center',
},
text: {
marginLeft: 12,
fontSize: 16,
},
photo: {
height: 40,
width: 40,
borderRadius: 20,
},
separator: {
flex: 1,
height: StyleSheet.hairlineWidth,
backgroundColor: '#8E8E8E',
}
});
class Main extends React.Component {
constructor(props){
super(props);
const ds = new ListView.DataSource({rowHasChanged: (r1, r2) => r1 !== r2});
this.state = {
dataSource: ds.cloneWithRows(['row 1', 'row 2'])
}
}
componentDidMount(){
Api.getCategories()
.then((res) => {
this.setState({
dataSource: ds.cloneWithRows(res)
})
})
.catch();
}
render() {
return(
<ListView
style={styles.container}
dataSource = {this.state.dataSource}
renderRow={(data) => <CategoryRow {...data} />}
/>
)
}
}
module.exports = Main;
And the code for categoryRow is:
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 12,
flexDirection: 'row',
alignItems: 'center',
},
text: {
marginLeft: 12,
fontSize: 16,
},
photo: {
height: 40,
width: 40,
borderRadius: 20,
},
});
const CategoryRow = (props) => (
<View style={styles.container}>
<Text style={styles.text}>
${props.name}
</Text>
</View>
);
export default CategoryRow;
Example of data :
[
{
"categoryId": 1,
"code": "15",
"name": "Photography",
"description": "Are you a photo junkie? Then join the “snap pack” and travel to some of the most photogenic places on earth. Our photography trips put you on an itinerary specially geared towards getting the perfect pic, with a group of like-minded travellers. Learn new tricks, share your knowledge, and never worry about taking the time to get the shot. Bonus: someone always has an extra lens cap.",
"categoryTypeId": 1,
"categoryType": {
"categoryTypeId": 1,
"name": "Activity"
}
}
]
Can someone please help me to find out where is the problem and how to resolve this error?
I think ListView uses the ScrollView props. See here http://facebook.github.io/react-native/releases/0.35/docs/listview.html#scrollview
From the error, it seems you should specify alignItems: 'center' in the contentContainerStyle prop of the ListView. Remove it from styles.container
<ListView contentContainerStyle={{alignItems: 'center'}}>
....
</ListView>
render() {
return(
<View style={{
alignItems: 'center'
}}>
<ListView
style={styles.container}
dataSource = {this.state.dataSource}
renderRow={(data) => <CategoryRow {...data} />}
/>)
</View>
}
