Whenever I select a new color and alert it, it shows me the color selection but, doesn't update the background color of my list.
Any idea what I am doing wrong.
Try this:
Instead of storing the color in a global variable, you should store it in the component's state. If you don't know what state means in React, consider reading this article.
I see you call a setColor function to change the variable my. Instead you could call
this.setState({currentColor: 'red'})
and then in a render() method, you could append it to an array to overwrite the default style:
<SomeComponent style={[styles.myStyle, {backgroundColor: this.state.currentColor}]}/>
The point of doing this is that setState triggers a new UI rendering.

I have an array of items which I have retrieved from an Object. The array has 5 items. It looks like this:
I have saved the array in my state as :
this.state={
serviceDetails: planDetails[0].nbs_plans.map(service => service.extension_attributes.productServicetList.map(name=>name.name)),
}
Now, I am trying to render the array in my component using map function like :
{
this.state.serviceDetails.map((serviceName) => {
return (
<SelectableChips initialChips={serviceName} />
);
})
}
But the problem is all the arrays are coming together at the same place as shown below:
The way it should be is : The first "See more" should be at the first section, the 2nd at the 2nd and so on.
My complete code for this component looks like this:
//This is an example code for FlatList//

};
var result = planDetails.filter(d => {
return d.nbs_plans[0].name = "TruComplete℠ Lawn Care Plan";
});
// alert(Object.keys(planDetails).length);

Can someone please guide me how to proceed.
As each plan has as productServicetList, create a object serviceDetails where the key is the planName and the value is productServicetList.
this.state={
serviceDetails: planDetails[0].nbs_plans.reduce(
(acc, service) => ({
...acc,
[service.name]: service.extension_attributes.productServicetList.map(
name => name.name
)
}),
{}
);
}
Then render the serviceDetail as follows
{
this.state.serviceDetails[item].map(serviceName => {
return <SelectableChips initialChips={serviceName} />;
});
}

I am a beginner coder on react native and would like to have some help here. The code works on iOS emulator with EXPO but doesnt work on my Android Device.
Thanks in Advance!
Most likely posts is not a array, check the type of posts.
I am using react-native-simple-picker in my app which works fine in my project if I use the default show button but I would like to show the picker when I use a different button in my project. It looks like this.refs.picker.show() in ProposalPicker.js is the function that needs to be called, but I am not sure how to access this from another component file. Currently my code results in the following error - `Cannot read property 'show' of undefined. Appreciate any help.

To call methods via refs you need to have a ref assigned to an already mounted component. Therefore you can't say new ProposalPicker().refs.picker.show() because refs.picker does not exist until the component is mounted. You Should have your button and picker components in the same parent, that way you can easily create a ref in that parent, assign it, and call methods from it:
Also you should use callback refs instead of string refs because string refs are deprecated. In that case it would look like:
constructor(props){
super(props)
this.state = ...
this.picker = React.createRef() // make the ref
}
Then assign the ref:
<SimplePicker
ref={this.picker}
And then you can make an function to call when your button is pressed:
showPicker = () => {
if (this.picker.current) {
this.picker.current.show()
}
}

You can use Flexbox's justifyContent feature to force the TextInput to the left and the search icon to the right. If you put a border on the container and not the TextInput, the entire thing will appear as there is a search icon fixed onto the right of the TextInput, when, in reality, they are two separate components.
// styles
const styles = StyleSheet.create({
searchBox: {
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
borderWidth: 1,
borderColor: 'black',
},
});
// the component
<View style={styles.searchBox}>
<TextInput ...yourprops />
<Avatar ...yourprops />
</View>
If you want to read more about justifyContent and how godly Flexbox is, you should check out Chris Coyier's Flexbox guide.
There seems to be a un-changeable margin on views using the react-native-scrollable-tab-view module. I can seem to get my code to fit to page on the views nested inside the scrollable-tab-view component. Any ideas? here's the code of the page presented:
'use strict';
import React from 'react';
import {
StyleSheet,
View,
Image,
Text,
TextInput
} from 'react-native';
//dimensions
var Dimensions = require('Dimensions');
var window = Dimensions.get('window');
//modules/pages
var StepImage = require('../components/StepImage');
import Icon from 'react-native-vector-icons/FontAwesome';
import {Actions} from "react-native-router-flux";
var NavHeader = require('../components/Header');
var UserStat = require('../components/UserStat');
var UserCircle = require('../components/UserCircle');
var Button = require('../components/Button');
var Data = require('../stores/userDiets');
var NavigationBar = require('react-native-navbar');
var Profile = React.createClass({
getInitialState: function() {
return {
};
},
render: function() {
var Keywords = Data.diets;
return (
<View style={[styles.container]}>

var styles = StyleSheet.create({

module.exports = Profile;
And here's what it looks like:
You have to set automaticallyAdjustContentInsets={false} in your ListView (or ScrollView). Details here:
