I am developing a project with react native. I have a header with a Text and an Icon.
const Header = ({ navigation, state }) => (
<View style={styles.header}>
<View style={styles.identidadeAppContainer}>
<View style={styles.nomeAppContainer}><Text style={styles.nomeAppText}>BigodeAPP</Text></View>
<View style={styles.logoAppContainer}><Image style={styles.imageLogo} source={Images.logoBigodeApp}></Image></View>
</View>
<View style={styles.iconContainer}>
{
!state ?
<Icon name="angle-down" size={25} color={colors.secundary} />
:
<Icon name="cut" size={25} color={colors.secundary} />
}
</View>
</View>
)
I call the Header inside my APP:
<Header state={stateMenu} />
stateMenu is a boolean variable which changes according to the user's actions.
However, even with stateMenu changing value, I am not able to re-embed the header to make the Icon later.
How can I do it?
I think, you can do by using this way:
const Header = ({ navigation, state }) => (
<View style={styles.header}>
<View style={styles.identidadeAppContainer}>
<View style={styles.nomeAppContainer}><Text style={styles.nomeAppText}>BigodeAPP</Text></View>
<View style={styles.logoAppContainer}><Image style={styles.imageLogo} source={Images.logoBigodeApp}></Image></View>
</View>
<View style={styles.iconContainer}>
<Icon name={state ? "cut" : "angle-down"} size={25} color={colors.secundary} />
</View>
</View>
)
Theres a one line if statement on the name prop

I'm trying to wrap my flat list and trying to show an Icon after last index of Flatlist. I had tried but it works fine on a single row. when we data goes to next row it would not work.
Here is my flat list code. Modal and Input both are my custom component.
const renderItem = ({item}) => {
return (
<TouchableOpacity style={[styles.tagPostContainer, styles.viewTagContainer]}>
<AppText
type={'input'}
label={`#${item}`}
color={colors.placeholder}
containerStyle={[styles.tagPostInactiveTxt, styles.BgAddedTag]}
/>
</TouchableOpacity>
);
};
return(
<>
<View style={{flexDirection:'row',justifyContent:'flex-start'}}>
<FlatList
data={tags}
renderItem={renderItem}
keyExtractor={keyExtractor}
contentContainerStyle={styles.TagFlatlist}
/>
<TouchableOpacity
style={styles.plusIconContainer}
onPress={() => setVisible(true)}>
<CreateBuildIconFocus height={13} width={13} />
</TouchableOpacity>
</View>
<Modal
visible={visible}
buttonLabel={'Done'}
containerWidth={width / 1.7}
onCancel={onCancel}
onSubmit={onClick}
containerHeight={Platform.OS === 'android' ? 200 : 200}>
<Input
placeholder={'Add Tags'}
autoFocus={true}
minWidth={120}
maxWidth={150}
value={tag}
onChangeText={text => setTag(text)}
/>
</Modal>
</>
)
FlatList styles:
TagFlatlist: {
flexDirection: 'row',
flexWrap: 'wrap',
alignItems: 'center',
},
Here is my design screen.
I find a solution for this. You can implement ListFooterComponent that used for showing something on end of flatlist. Here you can see more details of ListFooterComponent.
Here are the code of Flatlist.
return(
<FlatList
data={tags}
renderItem={renderItem}
keyExtractor={keyExtractor}
ListFooterComponent={
<TouchableOpacity
style={styles.plusIconContainer}
onPress={() => setVisible(true)}>
<CreateBuildIconFocus height={13} width={13} />
</TouchableOpacity>
}
contentContainerStyle={styles.TagFlatlist}
/>
)
I'm making an app with expo react native, and I made a collapse that shows profile information about all users on my SQLite database.
I added a button (touchableopacity) inside the collapse and my idea is to edit information in the input where I'm showing information, but i don't know how to link the button press to the profile where is being touched.
so my code is as follows (i deleted styles to make it cleaner to see):
render(){
const miLista = this.state.datos.map((item) => //this is "list" and it works(show information of each profile and shows the button of each profile when i open the collapse of each on of them)
<ScrollView style={styles.container}>
<Collapse>
<CollapseHeader>
<Text>{item.id} {item.nombre}</Text> //here shows id and name (from sqlite data)
</CollapseHeader>
<CollapseBody >
<View key={item.id} >
<Text >Nombre</Text>
<TextInput
value={item.nombre}
onChangeText={(val) => this.setState({ nombre: val})}/>
<Text style=>Rut</Text>
<TextInput
value={item.rutPersona}
onChangeText={(val) => this.setState({ rutPersona: val})}/>
<Text >Clave</Text>
<TextInput
value={item.clave}
onChangeText={(val) => this.setState({ clave: val})}/>
{this.boton(item.id)}
</View>
</CollapseBody>
</Collapse>
</ScrollView>
);
return(
<View >
<SafeAreaView >
<TouchableOpacity
onPress={() => this.props.navigation.openDrawer()}>
<FontAwesome5 name="bars" size={24} color="#161924"/>
</TouchableOpacity>
</SafeAreaView>
<Text>Perfiles</Text>
<ScrollView>
{miLista}
</ScrollView>
</View>
);
};
so i needed to add .bind to the onpress of my button and pass the data: like this
boton(id,nombre,rutPersona,clave){
return(
<TouchableOpacity
key={id}
style={styles.boton}
onPress={this.funcionBoton.bind(this,nombre,rutPersona,clave,id)}
>
<Text>SAVE </Text>
</TouchableOpacity>
);
};
I've been trying to use Tap Gesture Handler in my React Native project but I'm facing some problem with nested gestures. I've one parent TapGestureHandler(let's call it A) and and child TapGestureHandler(let's call it B). When I click on B then A is also getting executed. Please help me to solve this problem.
Here's my code for TapGestureHandler A:
<TapGestureHandler
ref={ref}
onHandlerStateChange={() => console.log("1")}>
<Animated.View>
<View style={styles.container}>
<View style={styles.leftContainer}>
<ProfilePic image={user.image} />
</View>
<View style={styles.rightContainer}>
<PostCardHeader user={user} />
<Discription discription={discription} />
<View style={styles.gridContainer}>
<ImageGrid waitFor={ref} images={attachedfiles} />
</View>
<Footer />
</View>
</View>
</Animated.View>
</TapGestureHandler>
Here's my code for TapGestureHandler B:
const ImageGrid = ({waitFor}) => {
return (
<TapGestureHandler
waitFor={waitFor || undefined}
onHandlerStateChange={() => console.log("2")}>
<Animated.View style={{ flex: 1 }}>
<Image
style={styles.image}
source={images[0]} />
</Animated.View>
</TapGestureHandler>
)
}
I am trying to implement the modal component in this app and for some reasons, I cant make it work. I have done it in another app and even though everything looks as it should in this one, it still doesn't work, it just doesn't toggle!
Here is my code (i call toogleModal() here ):
<TouchableOpacity
activeOpacity={1}
style={styles.slideInnerContainer}
//onPress={() => { alert(`You've clicked '${rest_name}'`); }}
onPress={() => this.toggleModal(rest_name)}
>
<View style={styles.shadow} />
<View style={[styles.imageContainer, even ? styles.imageContainerEven : {}]}>
{this.image}
<View style={[styles.radiusMask, even ? styles.radiusMaskEven : {}]} />
</View>
<View style={[styles.textContainer, even ? styles.textContainerEven : {}]}>
<View style={{ flexDirection: 'row' }}>
{uppercaseTitle}
{ratings}
</View>
<Text
style={[styles.subtitle, even ? styles.subtitleEven : {}]}
numberOfLines={2}
>
{rest_location}
</Text>
</View>
</TouchableOpacity>
Now here is the toggleModal() which should set the state and then call the onPressItem() :
toggleModal = (item) => {
this.setState({ isModalVisible: !this.state.isModalVisible });
this.onPressItem(item);
};
and onPressItem() :
onPressItem = (item) => {
return (
<ThemeProvider theme={theme}>
<Modal animationIn="rubberBand" animationOut={"bounceOut"}
isVisible={this.state.isModalVisible}
onBackdropPress={() => this.setState({ isModalVisible: false })}
>
<View style={{ flex: 1 }}>
{item}
</View>
<View style={{ flex: 1 }}>
<Button title="Hide modal" onPress={this.toggleModal} />
</View>
</Modal>
</ThemeProvider>
)
};
Now, remember this code is taken from another app where modal is working perfectly!
Most probably your issue with click option is connected with incorrect import TouchableOpacity from correct module. Check if you are importing from react-native:
import { TouchableOpacity } from 'react-native';
change this line
onPress={() => this.toggleModal(rest_name)}
to this:
onPress={() => {this.toggleModal(rest_name)}}
you only need to put the function call in brackets
I am doing react native application. In that, One screen have custom tabs in centre of the screen.
My screen is like,
top view around 200px height with some text lines showing.
After that, Custom tabs as picture attached.
After that, I am showing for first tab on tap flat list data.
I have checked online forums and tutorials, According to tab bar, We can show either top or bottom screen with tabs.
But, How to show tabs with customisation like my requirement.
I have 4 tabs, and each tab has same top view which I mentioned in above (some text lines), And if I tap on each tab, different data bottom page should show.
Like,
First tab with some flat list,
second tab with some text lines,
likewise all tabs has different layout in bottom screen.
As I am very new to react native. How to achieve this?
Due to privacy policy, I am unable to post complete screenshot.
Here is my code.
Screen.js
onClickTelugu = () => {
alert("you clicked onClickTelugu")
}
onClickTamil = () => {
alert("you clicked onClickTamil")
}
onClickHindi = () => {
alert("you clicked onClickHindi")
}
onClickEnglish = () => {
alert("you clicked onClickEnglish");
}
render(item) {
return (
<View style={styles.container}>
<View style ={styles.Container}>
<Text style={styles.textStyle}>
Some Text
</Text>
<View style={styles.somestyles}>
<TouchableOpacity onPress={this.onClick}>
<Image
style={styles.somestyles}
source={MenuImage}
/>
</TouchableOpacity>
<TouchableOpacity onPress={this.onClick}>
<Image

</TouchableOpacity>

</View>
<View style={styles.somestyles}>
<Text style={styles.somestyles}>some text</Text>
<Text style={styles.somestyles} >some text</Text>
<Text style={styles.somestyles}>date</Text>
<Text style={styles.somestyles}>some other date</Text>
</View>
</View>
</View>
<View style = {styles.tabContainer}>
<View style ={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={this.onClickTelugu}>
<Image
style={styles.tabItemsImages}
source={image}
/>
</TouchableOpacity>
<Text style={styles.tabTextItems} onPress={this.onClickTelugu}>Telugu</Text>
</View>
<View style={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={this.onClickTamil}>
<Image
style={styles.tabItemsImages}
source={image}
/>
</TouchableOpacity>
<Text style={styles.tabTextItems} onPress={this.onClickTamil}>Tamil</Text>
</View>
<View style={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={this.onClickHindi}>
<Image
style={styles.tabItemsImages}
source={image}
/>
</TouchableOpacity>
<Text style={styles.tabTextItems} onPress={this.onClickHindi}>Hindi</Text>
</View>
<View style={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={this.onClicEnglish}>
<Image
style={styles.tabItemsImages}
source={image}
/>
</TouchableOpacity>
<Text style={styles.tabTextItems} onPress={this.onClicEnglish}>English</Text>
</View>
</View>
<View style = {styles.flatListContainer}>
<FlatList style = {styles.flatList}
showsVerticalScrollIndicator = {true}
data = {this.state.dataArray}
renderItem = {({item}) => (
<TouchableWithoutFeedback onPress={ () => this.flatListItemHandler(item)}>
<Image
style={styles.flatListArrowImage}
source={image}
/>
</View>
<View style={styles.flatListItemInsideSeparator}>
)
}
ItemSeparatorComponent = {() => (
<View style={{height:15, backgroundColor:'#F8F8F8'}}/>
)}
/>
</View>
</View>
);
}
}
And I have to show overlay tab images too. If 1st tab tapped, 2,3,4
tabs images should be like delighted images. Like
highlighted/delighted images.
Ok you need to give this component it's own state to keep track of what you want to show in the lower section. then you should replace all of your onClick events with just one onClick event that you pass different languages to. For Example this.onClickTelugu becomes () => this.onClick('telugu'), then your onClick event should be:
onClick = (language) => {
this.setState({selectedLanguage: language})
}
then in your renderBottomContent function, you can render different things depending on what this.state.selectedLanguage is.
something like...
class MyComponent extends Component {
constructor(props) {
super(props)
this.state = { selectedLanguage: null}
}
onClick = (language) => {
this.setState({selectedLanguage: language})
}
renderBottomContent = () => {
const {selectedLanguge} = this.state
switch(selectedLanguage) {
case "telugu":
return <View><Text>Telugu</Text></View>
case "tamil":
return <View><Text>Tamil</Text></View>
case "hindi":
return <View><Text>Hindi</Text></View>
case "english":
return <View><Text>English</Text></View>
default:
return <View><Text>No Language Selected...</Text></View>
}
}
render() {
...
<View style ={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={() => this.onClick('telugu')}>
<Image style={styles.tabItemsImages} source={image} />
<Text style={styles.tabTextItems}>
Telugu
</Text>
</TouchableOpacity>
</View>
<View style ={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={() => this.onClick('tamil')}>
<Image style={styles.tabItemsImages} source={image} />
<Text style={styles.tabTextItems}>
Tamil
</Text>
</TouchableOpacity>
</View>
...
// after all the other tab buttons, render bottom content depending on the component state
{this.renderBottomContent()}
}
}
