I am want to make a draggable section list. Where I can drag one item from the section list and move it to another section.
I am try to do this using.
react-native-draggable-flatlist
Issue is that when I select an item and drage it. It takes the whole list.
import React, { FC, useState } from "react";
import { Text, View, StyleSheet, TouchableOpacity } from "react-native";
import DraggableFlatList, {
RenderItemParams,
ScaleDecorator,
} from "react-native-draggable-flatlist";
import { GestureHandlerRootView } from "react-native-gesture-handler";
import { Data } from "./data";
import Example from "./example";
interface Item {
header: string;
data: string[];
}
const DATA: Item[] = [
{
header: "A",
data: ["A1", "A2", "A3", "A4", "A5", "A6", "A7", "A8", "A9", "A10"],
},
{
header: "B",
data: ["B1", "B2", "B3", "B4", "B5", "B6", "B7", "B8", "B9", "B10"],
},
];
interface IList {
item: string;
selected: (item: string) => void;
active: boolean;
}
const List: FC<IList> = ({ item, selected, active }) => {
const getSelected = () => {
console.log("item", item);
selected(item);
};
return (
<TouchableOpacity
style={[
styles.draggableContainer,
{
backgroundColor: active ? "blue" : "white",
},
]}
onLongPress={getSelected}
onPress={getSelected}
>
<Text style={styles.text}>{item}</Text>
</TouchableOpacity>
);
};
export default function App() {
const renderContent = (item: Item, drag: () => void, isActive: boolean) => {
return (
<View style={styles.item}>
{item?.data?.map((seat) => (
<List key={seat} item={seat} selected={drag} active={isActive} />
))}
</View>
);
};
const renderSectionHeader = (section: Item) => (
<View style={styles.header}>
<Text style={styles.headerText}>{section.header}</Text>
</View>
);
const renderItem = ({ item, drag, isActive }: RenderItemParams<Item>) => (
<View style={{ flex: 1 }}>
<View>{renderSectionHeader(item)}</View>
<View style={{ flex: 1 }}>{renderContent(item, drag, isActive)}</View>
</View>
);
return (
<GestureHandlerRootView style={{ flex: 1 }}>
<View style={styles.container}>
<DraggableFlatList
data={DATA}
renderItem={renderItem}
keyExtractor={(item, index) => `draggable-item-${item?.header}`}
/>
</View>
</GestureHandlerRootView>
);
}
const styles = StyleSheet.create({
item: {
borderRadius: 5,
marginVertical: 8,
marginHorizontal: 16,
},
header: {
backgroundColor: "#f9c2ff",
height: 30,
justifyContent: "center",
paddingLeft: 10,
},
headerText: {
fontSize: 16,
fontWeight: "bold",
},
text: {
fontSize: 18,
},
draggableContainer: {
flexDirection: "column",
flex: 1,
paddingVertical: 10,
},
draggable: {
flex: 1,
},
container: {
flex: 1,
},
});
I have tryed using draxList but I was getting peformace issues. Draggable flat list has the best performance.
I have so many times react-native-draggable-flatlist
and I have the code for this below.
it works for me fine you can update your code like this.
<DragableFlatlist
ItemSeparatorComponent={() => (
<View style={styles.itemSeprator} />
)}
data={drag}
keyExtractor={(item) => item.id}
nestedScrollEnabled
onDragEnd={({ data }) => setDrag(data)}
renderItem={renderItemDrag}
showsVerticalScrollIndicator={false}
/>

I am unable to delete items.
This is App.js file main file:
import { useState } from "react";
import {
StyleSheet,
Text,
View,
Button,
TextInput,
FlatList,
} from "react-native";
import Goalresults from "./Componets/Goalresult";
export default function App() {
const [comingdata, SetData] = useState("");
const [listdata, setlistdata] = useState([]);
function fetchText(enteredText) {
SetData(enteredText);
}
function buttonPress() {
setlistdata((newdata) => [
...newdata,
{ text: comingdata, id: Math.random.toString() },
]);
}
I am passing id as parameter here and used filter method so that it filter all the id and delete id from the array list.
function deleteitem(id) {
setlistdata((newdata) => {
return newdata.filter((goal) => goal.id !== id);
});
}
return (
<View style={styles.container}>
<View>
<Text style={styles.goalsc}>Your Goals</Text>
</View>
<View style={styles.container1}>
<TextInput
style={styles.textInput}
placeholder="Add Your Goals here..."
onChangeText={fetchText}
/>
<Button title="Add Goal" onPress={buttonPress} />
</View>
<View style={styles.hello}>
<FlatList
data={listdata}
renderItem={(itemdata) => {
return (
<Goalresults
id={itemdata.item.id}
onDeleteItem={deleteitem}
text={itemdata.item.text}
/>
);
}}
keyExtractor={(item, index) => {
return item.id;
}}
/>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
paddingTop: 50,
paddingHorizontal: 16,
},
container1: {
flex: 1,
height: 120,
// paddingTop: 10,
flexDirection: "row",
justifyContent: "space-between",
alignItems: "center",
marginBottom: 20,
borderBottomWidth: 1,
borderBottomColor: "#808080",
},
textInput: {
width: "70%",
borderWidth: 1,
borderRadius: 10,
marginRight: 10,
padding: 8,
},
hello: {
flex: 3,
},
goalsc: {
fontSize: 20,
fontWeight: "bold",
paddingLeft: 140,
},
});
Second separated file:
import { View, Text, StyleSheet,Pressable} from "react-native";
function Goalresults(props) {
I used bind there to bind id:
return (
<Pressable onPress={props.onDeleteItem.bind(this,props.id)}>
<View style={styles.goalInput}>
<Text style={styles.textcolor}>{props.text}</Text>
</View>
</Pressable>
);
}
export default Goalresults;
const styles = StyleSheet.create({
goalInput: {
flex: 5,
borderRadius: 5,
paddingTop: 10,
backgroundColor: "#A020F0",
padding: 10,
margin: 10,
},
textcolor: {
color: "white",
},
});
There are a few issues with your code. I will list them as follows.
Inside Goalresults function change the bind on Pressable as
follows: <Pressable onPress={props.onDeleteItem.bind(props, props.id)}>
Inside buttonPress function correct this line { text: comingdata, id: Math.random().toString() }, you missed '()' paranthesis on random
Also on Goalresults add a key={itemdata.item.id}. It will help resolve the warning "duplicate keys".
Following is the complete code
App.js
export default function App() {
const [comingdata, SetData] = useState("");
const [listdata, setlistdata] = useState([]);
function fetchText(enteredText) {
SetData(enteredText);
}
function buttonPress() {
setlistdata((newdata) => [
...newdata,
{ text: comingdata, id: Math.random().toString() },
]);
}
function deleteitem(id) {
console.log('id: ', id)
setlistdata((newdata) => {
return newdata.filter((goal) => goal.id !== id);
});
}
return (
<View style={styles.container}>
<View>
<Text style={styles.goalsc}>Your Goals</Text>
</View>
<View style={styles.container1}>
<TextInput
style={styles.textInput}
placeholder="Add Your Goals here..."
onChangeText={fetchText}
/>
<Button title="Add Goal" onPress={buttonPress} />
</View>
<View style={styles.hello}>
<FlatList
data={listdata}
renderItem={(itemdata) => {
return (
<Goalresults
key={itemdata.item.id}
id={itemdata.item.id}
onDeleteItem={deleteitem}
text={itemdata.item.text}
/>
);
}}
keyExtractor={(item, index) => {
return item.id;
}}
/>
</View>
</View>
);
}

function Goalresults(props) {
return (
<Pressable onPress={props.onDeleteItem.bind(props, props.id)}>
<View style={styles.goalInput}>
<Text style={styles.textcolor}>{props.text}</Text>
</View>
</Pressable>
);
}
I'm new here and in react-native.
I want render some data from IMDB Api with the "hook" method.
So I try to render data in a flatlist, I can see in the console that the data is retrieved properly in a jSon format witch is a good thing but when I open my app I don't see any rendering on the screen.
I try to use the 'Hook' method and not the 'classes' and I'm pretty sure that I don't use properly the useState method.
So any help or advices are welcome.
My code:
App
import React, { useState } from "react";
import {

FlatList,
} from "react-native";
// import films from "../Helpers/filmsData";
import FilmsItem from "./FilmsItem";
import getFilmsFromApiWithSearchedText from "../Api/TMDBApi";
const Search = () => {
const [films, setFilms] = useState([]);
const _loadFilms = () => {
getFilmsFromApiWithSearchedText("White").then(
(data) => setFilms({ film: data.results }),
console.log(films)
);
};
return (
<View style={styles.container}>
<TextInput style={styles.input} placeholder="Titre du film" />
<Button
style={styles.button}
title="Rechercher"
onPress={() => _loadFilms()}
/>
<FlatList
data={setFilms.films}
keyExtractor={(item) => item.id.toString()}
renderItem={({ item }) => <FilmsItem films={item} />}
/>
</View>
);
};
const styles = StyleSheet.create({

};
export default getFilmsFromApiWithSearchedText;
FilmItem:
import React from "react";
import { View, Text, StyleSheet, Image } from "react-native";
const FilmsItem = (props) => {
const film = props.film;
return (

});
export default FilmsItem;
const _loadFilms = () => {
getFilmsFromApiWithSearchedText("White").then(
(data) => setFilms({ film: data.results }),
console.log(films)
);
};
setFilms({ film: data.results }) will set an object, but you need an array in there.
Try to do something like this: setFilms(data.results)
use useState in this way
const _loadFilms = () => {
getFilmsFromApiWithSearchedText("White").then(
(data) => setFilms(data.results),
console.log(films)
);
};
then in Flatlist you can use like this
return (
<View style={styles.container}>
<TextInput style={styles.input} placeholder="Titre du film" />
<Button
style={styles.button}
title="Rechercher"
onPress={() => _loadFilms()}
/>
<FlatList
data={films}
keyExtractor={(item) => item.id.toString()}
renderItem={({ item }) => <FilmsItem films={item} />}
/>
</View>
);
I'm not getting how to get the current item object of a flat list
I used react-native-swipeout and react-native-swipe-list-view and in both examples I stuck.
And on google I found very big answers. Which are not pointing only the particular issue which confused me a lot.
the below is the deleted function when I used react-native-swipeout plugin
const swipeSettings = {
left: [
{
text: 'Delete',
onPress: () => {
console.log('-----delete-----');
},
type: 'delete',
},
}
All I need is to get the current item object data like below inside onpress() when i tapped the delete button .
{
id: 1,
prodName : "abcdefg",
}
That's all, I came from native script background and in that framework I never faced such issue. Because the documentation was crystal clear. But here In react native everything seems to be complicated for me.
Kindly any one help me.
<FlatList
data={data}
keyExtractor={(item) => item.id}
renderItem={({item, index}) => (
<Swipeout {...swipeSettings}>
<View style={styles.listView}>
<Text style={styles.listViewText}>{item.prodName}</Text>
</View>
</Swipeout>
)}
/>

So if I get you right you have one generic swipe setting that you want to adjust to each element in the list.
Try changing the renderItem of the Flatlist like this and let me know how it worked for you:
<FlatList
data={data}
keyExtractor={(item) => item.id}
renderItem={({ item, index }) => {
let right = [...swipeSettings.right]; <---- ADDED
let left = [...swipeSettings.left]; <---- ADDED
right[0].onPress = () => console.log('edit', item.prodName); <---- ADDED
left[0].onPress = () => console.log('delete', item.prodName); <---- ADDED
<Swipeout {...swipeSettings} {...{ right, left}} > <---- CHANGED
<View style={styles.listView}>
<Text style={styles.listViewText}>{item.prodName}</Text>
</View>
</Swipeout>
}}
/>
So what I have done here is sending the generic swipe settings to each instance of Swipeout but changed their "Left" and "Right" in order to overwrite their "onPress" function and adjust it to the rendered item.
I know it is hard to understand it like this and it's probably not the best explanation but I hope it will help you somehow.

This program is supposed to change the background color of each individual item from this list when it is clicked. For example, when one item is pressed it will turn from pink to blue. My main issue is figuring out how to make/ connect a function with the item so that it will change its background color.
import React, { useState } from 'react'; import { StyleSheet, Text, View, FlatList, TouchableOpacity } from 'react-native';
export default function App() {
const [people, setPeople] = useState([
{ name: 'Day 1', id: '1' },
{ name: 'Day 2', id: '2' },
{ name: 'Day 3', id: '3' },
]);
const pressHandler = (id) => {
setPeople((prevPeople) => {
return prevPeople.{/*changeColorfunction*/};
});
};
return (
<View style={styles.container}>
<Text>Task 1</Text>
<FlatList
numColumns={5}
keyExtractor={(item) => item.id}
data={people}
renderItem={({ item }) => (
<TouchableOpacity onPress={() => pressHandler(item.id)}>
<Text style={styles.item}>{item.name}</Text>
</TouchableOpacity>
)}
/>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
paddingTop: 40,
paddingHorizontal: 20,
backgroundColor: '#fff',
},
item: {
flex: 1,
marginHorizontal: 10,
marginTop: 24,
padding: 7,
backgroundColor: 'pink',
fontSize: 14,
},
});
I would suggest you wrap the item into its own component and handle the logic internally for each item.
// ListItem.js
export default function ListItem(props) {
const { name } = props;
const [pressed, setPressed] = useState(false);
const onPress = () => {
setPressed(prevPressed => !prevPressed);
}
return (
<TouchableOpacity onPress={onPress}>
<View style={{ backgroundColor : pressed ? 'red' : 'blue' }}>
<Text style={styles.item}>{props.name}</Text>
</View>
</TouchableOpacity>
);
}
const styles = StyleSheet.create({
item: {
flex: 1,
marginHorizontal: 10,
marginTop: 24,
padding: 7,
fontSize: 14,
}
});
// App.js
export default function App() {
const [people, setPeople] = useState([
{ name: 'Day 1', id: '1' },
{ name: 'Day 2', id: '2' },
{ name: 'Day 3', id: '3' }
]);
return (
<View style={styles.container}>
<Text>Task 1</Text>
<FlatList
numColumns={5}
keyExtractor={(item) => item.id}
data={people}
renderItem={({ item }) => (
<ListItem name={item.name} />
)}
/>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
paddingTop: 40,
paddingHorizontal: 20,
backgroundColor: '#fff',
}
});
I have a TabView inside a ImageBackground in react-native app. The TabView does not show up but it is displayed when given as a parent element.
<ImageBackground source={require('../assets/images/loginBg.png')} style={styles.container}>
<TabView
navigationState={this.state}
renderScene={SceneMap({
first: FirstRoute,
second: SecondRoute,
})}
onIndexChange={index => this.setState({ index })}
initialLayout={{ width: Dimensions.get('window').width }}
style={innerStyles.innerContainer}
/>
</ImageBackground >
);
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#ffffff',
alignItems: 'center',
justifyContent: 'center',
width: '100%',
height: '50%',
},
});
const innerStyles = StyleSheet.create({
innerContainer: {
flex: 1,
},
scene: {
flex: 1,
},
});
You have to reconstruct the headers using the RenderTabBar function. I made an example of using the imageBackground that you want in the answer.
import * as React from 'react';
import { View, TouchableOpacity, StyleSheet, ImageBackground } from 'react-native';
import { TabView, SceneMap } from 'react-native-tab-view';
import Animated from 'react-native-reanimated';
const FirstRoute = () => (
<View style={[styles.container, { backgroundColor: '#ff4081' }]} />
);
const SecondRoute = () => (
<View style={[styles.container, { backgroundColor: '#673ab7' }]} />
);
export default class TabViewExample extends React.Component {
state = {
index: 0,
routes: [
{ key: 'first', title: 'First' },
{ key: 'second', title: 'Second' },
],
};
_handleIndexChange = index => this.setState({ index });
_renderTabBar = props => {
const inputRange = props.navigationState.routes.map((x, i) => i);
return (
<View style={styles.tabBar}>
{props.navigationState.routes.map((route, i) => {
const color = Animated.color(
Animated.round(
Animated.interpolate(props.position, {
inputRange,
outputRange: inputRange.map(inputIndex =>
inputIndex === i ? 255 : 0
),
})
),
0,
0
);
return (
<ImageBackground
source={{uri: "https://cdn.pixabay.com/photo/2015/07/27/19/47/turtle-863336__340.jpg"}}
style={{flex:1}}
>
<TouchableOpacity
style={styles.tabItem}
onPress={() => this.setState({ index: i })}>
<Animated.Text style={{ color }}>{route.title}</Animated.Text>
</TouchableOpacity>
</ImageBackground>
);
})}
</View>
);
};
_renderScene = SceneMap({
first: FirstRoute,
second: SecondRoute,
});
render() {
return (
<TabView
navigationState={this.state}
renderScene={this._renderScene}
renderTabBar={this._renderTabBar}
onIndexChange={this._handleIndexChange}
/>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
tabBar: {
flexDirection: 'row',
paddingTop: 24,
},
tabItem: {
flex: 1,
alignItems: 'center',
padding: 16,
},
});
