I get an array from firebase, it is now sorted alphabetically. If an object contains 'routes' then it will get the text 'Bekijk' button otherwise the text 'coming soon' button, what I would like is that the objects with the name 'Bekijk' are displayed first and then the other objects alphabetically order, does anyone know if that is possible?
This is my code:
import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View, Image, ImageBackground, StatusBar, ScrollView, Dimensions, TouchableOpacity} from 'react-native';
import { Header, Icon,Button,Rating, AirbnbRating } from 'react-native-elements';
import firebase from 'react-native-firebase';
class routeScreen extends Component {
constructor(props){
super(props);
this.state = {
goverments: [],
}
}
getGovermentData = () => {
let ref = firebase.database().ref('Goverments');
ref.on('value' , snapshot =>{
var state = snapshot.val();
this.setState({
goverments: state,
})
console.log(state);
})
}
componentWillMount(){
this.getGovermentData();
}
render() {
const width = {
width: (Dimensions.get('window').width / 2),
};
return (
<ScrollView>
{
this.state.goverments.sort(function(a, b) {
if(a.name.toLowerCase() < b.name.toLowerCase()) return -1;
if(a.name.toLowerCase() > b.name.toLowerCase()) return 1;
return 0;
}).map((item, i) => (
<View style={[styles.cards, { backgroundColor: (i % 2 == 0) ? '#D1A96E' : '#A58657' }]}>
<View style={styles.leftcolum}>
<Text style={styles.title}>{item.name}</Text>
<Text style={styles.undertitle}>4km - 5km - 7km</Text>
<Image source={require('./assets/images/stars.png')} style={styles.stars}/>
<Button buttonStyle={{

/>
</View>
<View style={styles.rightcolum}>
<Image source={{uri: item.logoUrl}} style={{width: 150, height: 68}}/>
</View>
</View>
))
}
</ScrollView>
);
}
}
const styles = StyleSheet.create({

});
export default routeScreen;
Structure of array:
what I would like:
now the array is shown in alphabetical order, that is good, I would only like to show object 1 of Goverments at the top because it contains the value routes, with the others the value routes being empty. so if it is filled, it must show it at the top
const Goverments = [
{
name: 'Valkenburg',
},
{
name: 'Eijsden-Margeaten',
},
{
name: 'Gulpen',
routes: [],
},
];
const SortedGoverments = Goverments.sort(function(a, b) {
if(a.routes) return -1; // new check
if(b.routes) return 1; // new check
if(a.name.toLowerCase() < b.name.toLowerCase()) return -1;
if(a.name.toLowerCase() > b.name.toLowerCase()) return 1;
return 0;
});
console.log("Goverments : ", Goverments);
console.log("SortedGoverments : ", SortedGoverments);

onChangeText={this.handleValueChange}
onFocus={this.handleFocus}
onBlur={this.handleBlur}
blurOnSubmit
/>
</View>
)
}
}
export default BliszFloatingLabel;
Instead of passing onChangeText like this onChangeText={this.handleValueChange} pass in a callback in BliszFloatingLabel and also in Login component.
onChangeText={(text)=>this.handleValueChange(text)}

Description
I am working on a react-native project using expo SDK36.
I want to do a swipe left/right list view. I use react-native-swipe-list-view to achieve it.
So far everything worked perfectly, the default example uses a fixed height: 50 per row, while I want to set the height of each row dynamically.
Every attempt where a failure, note that I already use <SwipeListView recalculateHiddenLayout={true} />
This is bad for the UX, since the default line is having a small height: 50, it is nearly impossible to drag the line on iOS and android properly.
Reproduction

import { Card } from 'react-native-paper';

Expect
I expect when using recalculateHiddenLayout={true}, to get the hidden row height calculated dynamically
Result Screenshots
On the web, I am able to set the height:
but I when using iOS and Android, the height is forced.
Environment
OS: ios/android/web
RN Version: expo SDK36
How can I set the height of each row dynamically?
Important edit
The problem is the fixed value here in the animation:
height: this.rowTranslateAnimatedValues[data.item.key].interpolate({
inputRange: [0, 1],
outputRange: [0, 200], // <--- here
})}]}
I have replaced it in the example with props.minHeight:
height: this.rowTranslateAnimatedValues[data.item.key].interpolate({
inputRange: [0, 1],
outputRange: [0, this.props.minHeight],
})}]}
It doesn't permit dynamic height, how can I get the row height dynamically?
Not sure where I go about declaring the array with which I want to search from, any assistance would be appreciated. I believe my issue is that I am declaring the "services' array in the incorrect area but I am not sure where else to put it! Or if the commas are the right character to be using in between strings/services

First, you are assigning an object to services array.
Second, you are not accessing the query state properly. It should be
const { query } = this.state

I am using axios to fetch the api, the api response is coming as an Array inside the array but nothing is coming on the screen.
I can get it with storing response upto message but then I can't have the loop on messages.
Please help.
Thanks in advance
When doing a GET request to the endpoint in your code the response looks as follows:
{
"status":{
"code":200,
"message":"Success"
},
"totalMessage":6,
"recentMessageId":228,
"response":[
...
]
}
Inside the response object there's an array of message objects so you can't use response.data.response.message when setting state. That part of your code needs to be:
this.setState({ group_msgs: response.data.response });
Now you should be able to iterate through the group_msgs object to get the message key value for each item in the array.
Also in the FlatList component you should have
keyExtractor={item => {
return item.message.m_id;
}}
Your renderItem seems to be wrong as well, see should be something like this:
renderItem={ ({item}) => {
let inMessage = (item.sender.usedId === this.state.userid) ? 'in' : 'out';
let itemStyle = inMessage ? styles.itemIn : styles.itemOut;
return (
<View style={[styles.item, itemStyle]}>
<View style={[styles.balloon]}>
<Text>{item.message.message}</Text>
</View>
</View>
);
}}
I strongly suggest you take a look at the structure of the response object since that's where you are failing at the moment.
