React native flat list not rendering items

I hope you're doing okay
I'm experiencing something weird with my react-native project, The FlatList items in some of the pages aren't displayed, even though I can see them when I console.log(json.items).
Earlier today, everything worked fine. all the pages displayed their lists as they should on my device. then I started working on a new search page on snack & I added status bar, I tested and it worked on snack before adding the new code and creating the new files in my app.
The issue I'm having now is, the list on the first page is displayed, subsequent pages after that do not show list items. including the new search page that works on snack
I'll go ahead and post my code now, the first set is for the page whose listitems are displayed correctly:
App.js
class ProfileActivity extends Component
{
// Setting up profile activity title.
static navigationOptions = ({ navigation }) =>
{
return {
title: 'Home',
headerStyle : {
backgroundColor: '#00b47a',
elevation: 0
},
headerTitleStyle: {
color: 'white'
},
cardStyle: { backgroundColor: '#fff' },
headerLeft: null,
headerRight: (
<View style={{ alignSelf: 'center', alignItems: 'center', display: 'flex', flexDirection: 'row', justifyContent: 'space-evenly'}}>
<Icon containerStyle={{ paddingRight: 10 }}
color='#fff' onPress={()=> navigation.getParam('openBottomSheet')()}
name="menu" />
<Icon containerStyle={{ paddingRight: 15 }}
color='#fff' onPress={()=> navigation.getParam('openSearchPage')()}
name="search" /></View>
)
}
};
constructor () {
super()
this.state = { toggled: false }
}
componentDidMount() {
this.props.navigation.setParams({ openBottomSheet: this.onOpenBottomSheet });
this.props.navigation.setParams({ openSearchPage: this.onOpenSearchPage });
}
onOpenBottomSheet = () => {
this.Standard.open();
}
onOpenSearchPage = () => {
this.props.navigation.navigate('sixth');
}
render() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center'}}>
<StatusBar
animated={true}
backgroundColor="#00b47a"
barStyle={'light-content'}
showHideTransition={'slide'}
hidden={false} />
<MarketList navigation={this.props.navigation} />
<RBSheet
ref={ref => {
this.Standard = ref;
}}
>
...
</RBSheet>
</View>
);
}
}
Market.js
export default class MarketList extends React.Component {
constructor(props) {
super(props)
this.state = {
items: '',
};
this.animateList = new Animated.Value(0);
}
componentDidMount() {
Animated.timing(this.animateList, {
toValue: 1,
duration: 500,
}).start();
}
render() {
const rowStyles = [
styles.itemList,
{ opacity: this.animateList },
{
transform: [
{ scale: this.animateList },
],
},
];
fetch('https://mvmarket.xyz/nativeuserapp/home.php')
.then((response) => response.json())
.then((json) => {
this.setState({
items: json.items,
})
})
.catch((error) => {
console.error(error);
});
return (
<View style={styles.container}>
<FlatList
data={this.state.items}
renderItem={({item}) => <TouchableOpacity onPress={()=>this.props.navigation.navigate("fourth",{market:item.name})}><Animated.View style={rowStyles}><View style={styles.item}><Text style={styles.market}>{item.name}</Text><Text style={styles.location}>{item.Location}</Text></View><View style={styles.go}><Icon name="arrow-right" color="#00b47a" /></View></Animated.View></TouchableOpacity>}
/>
</View>
);
}
}
This next set is for one of the pages that don't show list items
App.js
class ProductsActivity extends Component {
static navigationOptions =
{
title: 'Products',
headerStyle : {
backgroundColor: '#00b47a',
elevation: 0
},
cardStyle: { backgroundColor: '#fff' },
headerTitleStyle: {
color: 'white'
},
};
render() {
return(
<View>
<StatusBar
animated={true}
backgroundColor="#00b47a"
barStyle={'light-content'}
showHideTransition={'slide'}
hidden={false} />
<ProductsList navigation={this.props.navigation} />
</View>
);
}
}
Products.js
export default class ProductsList extends React.Component {
constructor(props) {
super(props)
this.state = {
items: '',
};
}
render() {
fetch('https://mvmarket.xyz/nativeuserapp/products.php')
.then((response) => response.json())
.then((json) => {
this.setState({
items: json.items,
})
}).catch((error) => {
console.error(error);
console.log(error);
});
return (
<View style={styles.container}>
<FlatList
data={this.state.items}
renderItem={({item}) => <TouchableOpacity onPress={()=>this.props.navigation.navigate("fifth",{market: this.props.navigation.state.params.market, type:item.type})} style={styles.itemList}><View style={styles.item}><Text style={styles.market}>{item.type}</Text></View><View style={styles.go}><Icon name="arrow-right" color="#00b47a" /></View></TouchableOpacity>}
/>
</View>
);
}
}
I'm leaving the URL there so you can confirm yourself that the data is actually fetched. Its driving me crazy, been on it for like 4 hrs.
Thank you

I think you don't really understand lifecycle methods of a React Component. It's important to understand those concepts before jumping into code. You can check here
When you put your fetch call in render, and on then you do a setState() you are making this infinitely. This happens because you are always providing new values to items.
The ideal is to have a model layer to handle those type of calls, but this is an architecture thing, to be less complex, you can use Container/Presentation pattern.
In the Container/Presentation pattern, you have a ContainerComponent which is responsible to do requests, handle callbacks, and provide data to the Presentation component, which would be responsible to just render things.
If you don't want to use this pattern, at least put this fetch call in componentDidMount method.

Thank you all for your suggestions, duly noted and appreciated.

I've fixed it, by changing
class SearchMarketActivity extends Component {
static navigationOptions = {
headerShown: false,
cardStyle: {
backgroundColor: 'white'
}
}
render() {
return(
<View>
<StatusBar
animated={true}
backgroundColor="#585858"
barStyle={'light-content'}
showHideTransition={'slide'}
hidden={false} />
<SearchMarket navigation={this.props.navigation} />
</View>
)
}
}
to
class SearchMarketActivity extends Component {
static navigationOptions = {
headerShown: false,
cardStyle: {
backgroundColor: 'white'
}
}
render() {
return(
<SearchMarket navigation={this.props.navigation} />
)
}
}
After, I added the StatusBar to the <SearchMarket /> component being imported

How do i get specific elements from webservice

I want to get specific the first two elements from a webservice and print it to a console it is returning me 1000 items. Can anyone guide me on how I can print only the first two elements
import React from "react";
import {StyleSheet,View,ActivityIndicator,FlatList,Text,TouchableOpacity} from "react-native";
export default class Source extends React.Component {
static navigationOptions = ({ navigation }) => {
return {
title: "Source Listing",
headerStyle: {backgroundColor: "#fff"},
headerTitleStyle: {textAlign: "center",flex: 1}
};
};
constructor(props) {
super(props);
this.state = {
loading: false,
items:[]
};
}
FlatListItemSeparator = () => {
return (
<View style={{
height: .5,
width:"100%",
backgroundColor:"rgba(0,0,0,0.5)",
}}
/>
);
}
renderItem=(data)=>
<TouchableOpacity style={styles.list}>
<Text style={styles.lightText}>{data.item.name}</Text>
<Text style={styles.lightText}>{data.item.email}</Text>
<Text style={styles.lightText}>{data.item.company.name}</Text>
</TouchableOpacity>
render(){
{
if(this.state.loading){
return(
<View style={styles.loader}>
<ActivityIndicator size="large" color="#0c9"/>
</View>
)}}
return(
<View style={styles.container}>
<FlatList
data= {this.state.dataSource}
ItemSeparatorComponent = {this.FlatListItemSeparator}
renderItem= {item=> this.renderItem(item)}
keyExtractor= {item=>item.id.toString()}
/>
</View>
)}
}
const parseString = require('react-native-xml2js').parseString;
fetch('http://192.168.200.133/apptak_service/apptak.asmx/Get_Item_Master')
.then(response => response.text())
.then((response) => {
parseString(response, function (err, result) {
console.log(response[0],response[1])
});
}).catch((err) => {
console.log('fetch', err)
})
const styles = StyleSheet.create({
container: {

flex: 1,
justifyContent: "center",
alignItems: "center",
backgroundColor: "#fff"
},
list:{
paddingVertical: 4,
margin: 5,
backgroundColor: "#fff"
}
});
I want it to be print on the console then I will modify it later to display it on the app. I am struggling to get this done Please help

You are parsing the response as string. If you want to print the first two item in console, you can do it like this bellow:
fetch('http://192.168.200.133/apptak_service/apptak.asmx/Get_Item_Master')
.then((response) => {
console.log(response.data[0],response.data[1])
}).catch((err) => {
console.log('fetch', err)
})

Perhaps what you need is the result?
parseString(response, function (err, result) {
console.log(result) // not console.log(response)?
});
Using JavaScript
fetch("http://192.168.200.133/apptak_service/apptak.asmx/Get_Item_Master")
.then((r) => r.text())
.then((t) => (new window.DOMParser()).parseFromString(t, "text/xml"))
.then((d) => console.log(d))
.catch((e) => console.error(e));

I am pretty new to react native and development in general i would highly apprecitate any help .I need to seprate the elements and display specific elements in the app.

As far as I can tell from your code, you are not passing the fetched data into your state. You're only logging it in the console:
parseString(response, function (err, result) {
console.log(response)
});
I think you should add the following pieces to your component:
1 . First of all set up the function to be called in your constructor, so it can access the state:
constructor(props) {
super(props);
this.state = {
loading: false,
items:[]
};
this.fetchRequest = this.fetchRequest.bind(this)
}
Create the actual function inside render:
fetchRequest() {
fetch('http://192.168.200.133/apptak_service/apptak.asmx/Get_Item_Master')
.then(response => response.text())
.then((response) => {
parseString(response, function (err, result) {
this.setState({ items: response });
});
}).catch((err) => {
console.log('fetch', err)
})
}
You need to call the fetchRequest function. You can do that in a lifecycle method of your component:
componentDidMount() {
fetchRequest();
}
Last thing is to create your Flatlist correctly:
<FlatList
data= {this.state.items}
renderItem={({ item }) => <Item title={item.title} />}
keyExtractor= {item=>item.id.toString()}
/>
Your data source is this.state.items, and not this.state.dataSource.
Unfortunately I have no idea what your data looks like, so I don't know how the keyExtractor and <Item> should be written. What I can tell you is that you will need unique IDs for your items.
You can read more about Flatlist in the React Native docs.

undefined is not an object (evaluating 'this.props.navigation")

My navigation suddenly broke down. So there are 3 screens/components, I am using react-navigation to navigate between them. First screen is to enter mobile phone number and password, it is sent to api, and some data is saved into state and passed to second screen, where i am enter code from sms and send another request to api, if response.status == 200, it goes to third screen. Navigation from 1st screen to 2nd works, but from 2nd to third is not. Error occurs when i am going to third screen.
FirstPage.js
export default class FirstPage extends React.Component {
constructor(props) {
super(props);
this.state = {
text: '',
password: '',
password2: ''
}
}
state = {
uuid: null
}
getCode(text, psw) {
fetch('url', {

'Content-Type': 'application/json'
},

})
.then(response => response.json())
.then(response => {

SecondPage.js
export default class SecondPage extends React.Component {
input = React.createRef();
constructor(props) {
super(props);
this.state = {

};
}
state = {

}
sendCode(uid, code) {
const body = new FormData
body.append("authentication", uid)
body.append("code", code)
fetch('url', {

Token: "2f30743e-014d-4f0f-8707-73ae550d8f14"
}
}).then(function (response) {
console.log(uid + "code is " + code)
console.log(response);
if (response.ok) {
this.props.navigation.navigate('ThirdPage');
} else {
console.log(response.status)
}
})
.catch((error) => {
console.error(error);
});
}
render() {
return (

ThirdPage.js
export default class ThirdPage extends React.Component {
render() {
return (
<View style={styles}>
<Text>
Hi there
</Text>
</View>
)
}
}
And finally App.js
class App extends React.Component {
render() {
return (<AppStackNavigator />)
}
}
const AppStackNavigator = createStackNavigator({
FirstPage: {
screen: FirstPage
},
SecondPage: {
screen: SecondPage
},
ThirdPage: {
screen: ThirdPage
}
}, {initialRouteName: 'FirstPage'})
export default createAppContainer(AppStackNavigator);
I don't really why it happens, because react-navigation says that all then screens from App.js is sent to every screen as this.props.navigation, so I can access them from anywhere.

The issue is because you have lost scope by not binding your functions, this means that you are no longer accessing the correct value of this. You can fix this issue by using arrow functions.
Rewrite your sendCode function in the following way, noticing the use of arrow functions
sendCode = (uid, code) => { // <- arrow function
const body = new FormData();
body.append('authentication', uid);
body.append('code', code);
fetch('url', {
method: 'POST',
body,
headers: {
Token: '2f30743e-014d-4f0f-8707-73ae550d8f14'
}
}).then(response => { // <- arrow function
console.log(uid + 'code is ' + code);
console.log(response);
if (response.ok) {
this.props.navigation.navigate('ThirdPage');
} else {
console.log(response.status);
}
}).catch((error) => {
console.error(error);
});
}
And finally update the code in your button to be.
<Button
title="send code"
onPress={() => this.sendCode(this.state.uuid, this.state.codeConf)} />

you need to bind and pass function definition to onPress prop of Button component in SecondPage.js.
<Button
title="send code"
onPress={()=>this.sendCode(this.state.uuid,this.state.codeConf)} />

Error: Cannot read property 'push' of undefined React Native

I'm currently trying to learn React Native based on this Tutorial: http://www.appcoda.com/react-native-introduction/
While copying most of the Code (small changes in text) I got this error:
Error: Cannot read property 'push' of undefined
This error occurs if I try to push a new Navigator View. Here is the striped down code (full code at the end but thought it's more readable to have just a short version here):
<TouchableHighlight onPress={() => this._rowPressed(eve)} >
_rowPressed(eve) {
this.props.navigator.push({
title: "Property",
component: SingleEvent,
passProps: {eve}
});
}
Maybe somebody can explain me why the this.props.navigator is undefined and how I can use it. I'm sorry for this basic question but I searched a lot and couldn't find a answer to this problem yet. I tryed to .bind(this) to the _rowPressed function and also rewrote everything to a NavigatorIOS View but nothing worked yet.
Would be nice if somebody could explain it to me.
All the best
Daniel

AppRegistry.registerComponent('allNightClub', () => allNightClub);

in your index.ios.js you're referencing a navigator here which isn't set at that moment.
<Dates navigator={navigator} />
So, as I've understood you have to options to work with NavigatorIOS:
1. NavigatorIOS as a child of your Tab
You need to define a navigator as a child of your TabViewItems which itself loads the appropriate view:
var styles = StyleSheet.create({
container: {
flex: 1,
}
});
<TabBarIOS.Item>
<NavigatorIOS
style={styles.container}
initialRoute={{
title: 'Dates',
component: Dates,
}}
/>
</TabBarIOS.Item>
2. NavigatorIOS as the root Element
class allNightClub extends Component {
render() {
return (
<NavigatorIOS
style={styles.container}
initialRoute={{
title: 'Index',
component: Index
}}
/>
);
}
}
That's the way it's worked for me. I put the original code of index.ios.js into Index.js and also did the following changes:
Index.js
<Dates
navigator={this.props.navigator}
/>
Dates.js
<TouchableHighlight onPress={() => this._rowPressed(eve)} underlayColor='#dddddd'>

From what I can deduct, your call to this.props.navigator should work, even without the bind-statements.
My first thoughts would be: is the navigator item passed to your Dates component from its parent?
return (
<Dates
navigator={navigator}
... />
Probably inside a renderscene function where you render your navigator..
What does your output look like from your console statement?
console.log(eve, this.props)

I ran into this issue today, the reason is that you need to call the screen where you're using this.props.navigator.push with the NavigatorIOS component. That will set the navigator prop. E.g.
<NavigatorIOS
style={styles.container}
initialRoute={{
title: '',
component: DemoScreen
}}
/>
Now in your DemoScreen you can use this.props.navigator.
