I'm developing an social apps whereby user can simply attach a website URL, and when other user click on it it will show a webpage within the apps.
For example as below
I'm using react navigation, is there a way can achieve this ?
RN > 0.59
Use react-native-webview.
Use WebView.
Example from official link.
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
class MyWeb extends Component {
render() {
return (
<WebView
source={{uri: 'https://github.com/facebook/react-native'}}
style={{marginTop: 20}}
/>
);
}
}
It will be better use WebView in your component having header and basic control as backbutton and closebutton.

I have seen this issue posted on stack overflow many times with no clear answer. I'm hoping this question can help me and others out.
I wish to render a URL in react native using react-native-webview
I started a blank react native project using expo init my-app. I ran npm i react-native-webview and react-native link react-native-webview. I then created a file defined as the following
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
class WebViewTest extends Component {
render() {
return (
<WebView
source={{ uri: 'https://www.google.com/' }}
style={{ marginTop: 20, width: 400, height: 400 }}
/>
);
}
}
export default WebViewTest;
My app.js imports and renders that file like the following
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
import WebViewTest from './Components/WebViewTest';
export default function App() {
return (
<WebViewTest />
);
}
I test this code by running expo start and I open up my project in a web browser.
I then see the following in the browser
I don't get any errors or warnings so where am I going wrong?
As Per The Expo Docs For WebView -
https://docs.expo.io/versions/latest/sdk/webview/
https://www.npmjs.com/package/react-native-webview
It Doesn't Work On Web Using EXPO
I am new to React Native and i am trying to implement the Instagram auth login in my app. I created the project using expo cli.
I have tried 2 solutions so far-
i used the instagram api provided for authentication https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=code...
this api returns me a HTML template, when i render that template inside WebView component of react native, it just shows the instagram splash screen with thumbnail icon and nothing more.
i used react-native-instagram-login npm module but that didn't work coz it's probably a native module and not supported by expo.
I have also looked upon auth0 module, but i guess it also is a native module itself.
Have you configured uri correctly with webView?
example.js
import React, { Component } from 'react';
import { WebView } from 'react-native';
class MyWeb extends Component {
render() {
return (
<WebView
source={{uri: 'https://github.com/facebook/react-native'}}
style={{marginTop: 20}}
/>
);
}
}
I'm trying to make the UI for my app in the below picture:
My App's UI
I follow the instruction of React Navigation to make the Custom Navigator according to the UI but it doesn't work in Android. The red screen appears with the message "Cannot Add a child that doesn't have a YogaNode to a parent without a measure function". Here is my code:
import React, { Component } from 'react';
import { createStackNavigator } from 'react-navigation';
import TabAboutScreen from './TabAbout';
import TabMyLessonScreen from './TabMyLesson';
import TabTeacherScreen from './TabTeacher';
import { ScrollView, View, Text } from '../../../components';
import TabNavigator from './TabNavigator';
import TopBar from './TopBar';
import styles from './styles';
import CourseHeader from './CourseHeader';
import theme from '../../../theme';
import i18n from '../../../i18n';
export const CourseDetailStackNavigator = createStackNavigator({
TabAbout: TabAboutScreen,
TabMyLesson: TabMyLessonScreen,
TabTeacher: TabTeacherScreen,
}, {
headerMode: 'none',
initialRouteName: 'TabAbout',
});
export default class TabCourseDetail extends Component {
static router = CourseDetailStackNavigator.router;
constructor(props) {
super(props);
this._handleOnBackButtonPress = this._handleOnBackButtonPress.bind(this);
}
_handleOnBackButtonPress() {
// do something
}
render() {
return (
<View style={styles.container}>
<TopBar textButton={i18n.t('CMBack')} title={i18n.t('CDCourseDetail')} onPress={this._handleOnBackButtonPress} />
<ScrollView
style={styles.scrollContainer}
stickyHeaderIndices={[1]}
showsVerticalScrollIndicator={false}
alwaysBounceVertical={false}
>
<CourseHeader />
<TabNavigator />
<View style={styles.test}>
<CourseDetailStackNavigator navigation={this.props.navigation} />
</View>
</ScrollView>
</View>
);
}
}
My evironment: react-navigation: 2.12.1, react-native: 0.55.4
I found out that the problem was that I put inside component by following the document of react navigation. It works well in iOS but doesn't work in Android.
Have you ever faced this problem. I'm looking forward to your solutions. Best regard.
Make sure you have not left any commented code in the return method and also have not left any text (string) without Text tag of react native.
I'm using the StatusBar component in react native (Android). Here is an example code from my App.js component:
import React, { Component } from 'react';
import { View, StatusBar } from 'react-native';
import { RootNavigator } from './components/Router';
export default class MainApp extends Component {
render() {
return (
<View style={{flex: 1}}>
<StatusBar backgroundColor='black' barStyle="light-content"/>
<RootNavigator />
</View>
);
}
}
The StatusBar is working properly when you launch the app, when you navigate through the entire app and when put in background and then return.
It's NOT working when exiting the app by pressing back button. When you launch the app again, the statusbar backgroundColor is suddenly grey (default color).
Is this a known bug or something? I can't figure out how to fix this.
Alright, shortly after submitting the question I found out about another strategy, using imperative API. I avoided it at first since according to official documentation:
For cases where using a component is not ideal, there
is also an imperative API exposed as static functions on the
component. It is however not recommended to use the static API and the
component for the same prop because any value set by the static API
will get overriden by the one set by the component in the next render.
Here is my revised code:
import React, { Component } from 'react';
import { View, StatusBar } from 'react-native';
import { RootNavigator } from './components/Router';
export default class MainApp extends Component {
componentWillMount() {
StatusBar.setBackgroundColor('black');
}
render() {
return (
<View style={{flex: 1}}>
<StatusBar backgroundColor='black' barStyle="light-content"/>
<RootNavigator />
</View>
);
}
}
It seems like this works properly now. When I press the back button and launch the app again the statusbar remains black. I won't declare this as the correct answer just yet in case someone has an explanation why this happens or a better solution.
Edit: This also appears to work only 90% of the time or so. I've noticed, once in a while, when pressing back button and returning the statusbar remained grey. It is absolutely boggling at this point, I suppose componentWillMount isn't always triggered?
Edit2: After switching to componentDidMount instead of componentWillMount as suggested, it seems to be working 100% of the time now.
I try to implement the hero animation like in the shoutem About extension. Basically, I add animationName to NavigationBar and the Image like in the extension. I also had to add ScrollDriver because it would error-ed otherwise. But it seems the NavigationBar does not pass the driver down to its child components, so I still got this error. Is it possible to implement the hero animation like what was demonstrated here? https://medium.com/shoutem/declare-peace-with-react-native-animations-e947332fa9b1
Thanks,
import { ScrollDriver } from '#shoutem/animation';
getNavBarProps() {
const driver = new ScrollDriver();
return {
hasHistory: true,
driver: driver,
title: 'Title',
navigateBack: () => this.props.navigation.dispatch(NavigationActions.back()),
styleName: 'fade clear',
animationName: 'solidify',
};
}
render () {
const driver = new ScrollDriver();
return (
<Screen styleName=" paper">
<View style={{height:68}}>
<NavigationBar {...this.getNavBarProps()} />
</View>
<ScrollView style={styles.container}>
<Image
styleName="large"
source={require('../Images/spa2.jpg') }
defaultSource={require('../Images/image-fallback.png')}
driver={driver}
animationName="hero"
/>
...
I'm the author of the article, from you question, I'm not sure are you trying to create an extension on shoutem or you just want to recreate animation in any other React Native app.
If you are creating an extension or CardStack from #shoutem/ui/navigation, you don't event need to care for ScrollDriver. It would be pushed throught the context to the ScrollView (imported from #shoutem/ui) and NavigationBar (imported from #shoutem/ui/navigation).
If you are creating your own React Native project to be able to do it like in article I suggest the following. At the root component of your app:
import ScrollView from '#shoutem/ui';
class App extends Component {
...
render() {
return (
<ScrollView.DriverProvider>
<App />
</ScrollView.DriverProvider>
);
}
}
Then you don't have to take care of initialization of ScrollDriver on each screen, if you use our components and a ScrollView it will push the driver where it needs to be. :) So your screen at the end would look like this:
import {
ScrollView,
NavigationBar,
Image
} from '#shoutem/ui';
class MyScreen extends Class {
render() {
return (
<Screen>
<NavigationBar animationName="solidify" />
<ScrollView>
<Image animationName="hero" />
</ScrollView>
</Screen>
);
}
}
The whole working example is here https://github.com/shoutem/ui/tree/develop/examples/RestaurantsApp/app
