I am using List from NativeBase to render data.
I have tried to setup it like this:
body = <List
dataArray={data}
renderRow={(rowData) =>
<Person
key={rowData.ID}
searchText={searchText}
person={rowData}
onSelect={this.onSelect}
/>}
onEndReached={this.onEndReached}
onEndReachedThreshold={10}
contentContainerStyle={{
flex: 1,
justifyContent: 'center',
flexDirection: 'row',
flexWrap: 'wrap',
alignItems: 'flex-start'}}
/>
to simply display "Persons" in gird. Person is simply Card from NativeBase:
<Card style={{width: deviceWidth>320 ? 320 : deviceWidth,flexGrow: 1}}>
...
</Card>
However this does not work as I expected and flexWrap is not doing anything. Everything is rendered in one row instead of wrapping into grid.
This worked for me:
Wrap the Card with a View:
<View style={ styles.itemStyle} >
<Card>
<CardItem>
.....
</CardItem>
</Card>
<View>
const styles = {
itemStyle:
width: 150,
height: 100
}

I'm using a Card from react-native-elements. Turns out I want to add an icon next to its title but I can't get it to look nice.
Here's my code:
<Card
//title={this.props.item.offer.amount + " " + this.props.item.request.good}
title={
<View style={{justifyContent: 'center'}}>
<View style={{display: "flex",flexDirection: "row", justifyContent: 'center'}}>
<Text style={{fontSize: 18, justifyContent: 'center', fontWeight: 'bold'}}>{this.props.item.offer.amount + " " + this.props.item.request.good}</Text>
<View style={{flexGrow: 1}} />
<Button
buttonStyle={styles.localize}
icon={<Ionicons name="md-locate" color={'white'} size={28} style={{alignSelf: 'center'}}/>}
onPress={() => this.props.navigation.push('Rastrear')}
/>
</View>
<View
style ={{
borderWidth: 0.5,
borderColor:'grey',
margin:2,
}}
/>
</View>
}
titleStyle={{textAlign: 'left'}}
containerStyle={{width: Dimensions.get('window').width-25}}>
...
</Card>
Turns out that looks like this:
What I want is to align the title and the icon vertically. How can I achieve this?
If comment out that "title" line you see inside of the Card and comment my personalized one it looks like this:
As you see the title here's centered vertically.
Update. styles.localize looks like this:
localize: {
padding: 4,
backgroundColor: '#FF5733',
borderColor: '#FF5733',
borderWidth: 2,
width: Dimensions.get('window').width-370,
borderRadius: 10,
justifyContent: 'center'
}
Actually, once you have already declared justifyContent to be center in the parent View, this would have effected the rest of the child Views to have this styling prop. What you can do is to replace justifyContent in the second View housing your Text and Icon components with alignItems. This should vertically align them in the space provided by your parent View.
Also, you can set a height constraint in the parent View and textAlignVertical in the Text for better alignment.
<View style={{justifyContent: 'center', height: 60}}>
<View style={{display: 'flex', flexDirection: 'row', alignItems: 'center'}}>
<Text style={{fontSize: 18, textAlignVertical: 'center', fontWeight: 'bold'}}>12 Mouses</Text>
<View style={{flexGrow: 1}} />
<Button
buttonStyle={styles.localize}
icon={<Icon name="md-locate" color={'white'} size={28} style={{alignSelf: 'center'}}/>}
onPress={() => {}}
/>
</View>
<View
style ={{
borderWidth: 0.5,
borderColor:'grey',
margin:2,
}}
/>
</View>
I have included a Snack here for testing. :)
When I click on my FlatList I can drag and move it in all directions (up/down/right left). Although the list appears to be vertical (maybe because of the styling), the scroll bar still appears horizontally. How can I disable this dragging?
This is how I am using the FlatList:
<FlatList
data={data.me.friends.nodes}
//horizontal={false}
//scrollEnabled={false}
renderItem={({ item }) => (
<FriendItem friend={item} originatorId={data.me.id}/>
)}
keyExtractor={(item) => item.id.toString()}
ListEmptyComponent={NoFriendsContainer}
/>
This is from the FriendItem's return
return (
<View style={styles.item}>
<TouchableOpacity
onPress={() =>
navigation.navigate('FriendDetails')
}>
<Thumbnail
style={styles.thumbnail}
source={{
uri:
'https://cdn4.iconfinder.com/person-512.png',
}}></Thumbnail>
</TouchableOpacity>
<View style={styles.nameContainer}>
<Text style={styles.userName}>{userName}</Text>
</View>
<View style={styles.deleteButtonContainer}>
<Button
rounded
style={styles.deleteButton}
onPress={() => onDeleteFriend(originatorId, friend.id)}>
<Icon name="trash-o" size={moderateScale(20)} color="black" />
</Button>
</View>
</View>
);
};
Styles for FriendItem:
export const styles = StyleSheet.create({
item: {
backgroundColor: 'white',
borderRadius: moderateScale(20),
padding: moderateScale(20),
marginVertical: moderateScale(8),
marginHorizontal: 16,
height: moderateScale(110),
width: moderateScale(360),
justifyContent: 'space-between',
flexDirection: 'row',
},
userName: {
paddingRight: 55,
paddingLeft: 10,
paddingTop: 20,
},
deleteButton: {
backgroundColor: '#31C283',
width: moderateScale(45),
justifyContent: 'center',
},
deleteButtonContainer: {
paddingTop: 12,
marginRight: 2,
},
thumbnail: {
height: 85,
width: 85,
marginLeft: 2,
paddingRight: 0,
position: 'relative',
},
nameContainer: {
flexDirection: 'row',
},
});
I also tried removing the TouchableOpacity but it made no difference.
What you can try. is below :
UPDATE:
<Flatlist
bounces={false}/>
try this here, or add bounces={false} in the top scrollView if its there
Hope it helps. feel free for doubts
This issue happened because of some times you have given a width to the parent view of flat list. like below.
<View style={{width: '90%'}}>
<FlatList/>
</View>
simply add the flatlist to the same width with bounces false.
<View style={{width: '90%'}}>
<FlatList
contentContainerStyle={{width: '90%'}}
bounces={false}
/>
</View>
by adding bounces=false, your flatlist will not be able drag to different directions.
I have a problem with KeyboardAvoidingView where my container seems to be overlapping my header when I clicked the text input like this
and I'm using header from react native elements
here is my code
<KeyboardAvoidingView style={styles.container} behavior="padding" enabled>
<Header
left={<IconWrapper
image={<Image source={img.icons.menu} style={{ width: normalize(26), resizeMode: 'contain', paddingHorizontal: normalize(5), marginHorizontal: normalize(5) }} />}
onPress={() => Actions.drawerOpen()} />}
title={'Activity Log'}
right={<View style={{ width: normalize(30) }} />}
/>
<View style={styles.innerContainer}>
<Text style={styles.dialogText}>{`Log my activity at ${time} as...`}</Text>
<View style={{marginVertical: 10}}>
{columns}
</View>
<TextInput
placeholder={"Additional Notes"}
/>
</View>
</KeyboardAvoidingView>
const styles = StyleSheet.create({
container: {
flex:1,
justifyContent: 'center'
},
innerContainer: {
justifyContent: 'center',
alignItems: 'center'
},
})
Here, I am displaying "icon="check-decagram" type="MaterialCommunityIcons" in center, but its just coming in center and 20 padding from top. I have to display it middle of the mobile screen. I tried may be I am doing some wrong .Please correct me .
return(
<ImageBackground source={BG} style={styles.imgBG}>
<ScrollView>
<View>
<Header title={title} icon={icon} navigation={navigation} />
</View>
<View style={{ flexDirection: 'column', backgroundColor: '#ffff',}}>
<View style={{
flexDirection:'column', backgroundColor:'#fff',alignItems:'center',paddingTop:20,justifyContent: 'center'}}>
<IconXL icon="check-decagram" type="MaterialCommunityIcons" style={{ color: 'green' }}/>
</View>
<View style={{
flexDirection:'row', backgroundColor:'#ffff',padding:20,flexWrap:'wrap'}}>
<SmallText textColor="grey" text={`v${updateResponse.updateStatusList.currentAppVersion} `}/>
<SmallText textColor="grey" text={`${updateResponse.updateStatusList.desc}`}/>
</View>
</View>
</ScrollView>
</ImageBackground>
)}
// Thanks
try to add two more property height: '100%' and width: '100%' in superview of icon,
like,
<View style={{flexDirection:'column',height: '100%',width: '100%',backgroundColor:'#fff',alignItems:'center',paddingTop:2,justifyContent: 'center'}}>
<IconXL icon="check-decagram" type="MaterialCommunityIcons" style={{ color:'green' }}/>
</View>
Hope this works for you,
Good luck.
You can try something like.
<View style={{
flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'blue'
}}>
<Text style={{backgroundColor: 'red'}}>
Your Text
</Text>
I am trying to set an icon inside a text input.
I know, there is this answer.
But it is not working as expected since the icon is outside of the TextInput, I need it to be inside.
This is what I am obtaining so far:
This is my code:
<View style={styles.InputContainer}>
<Ionicons
style={styles.IconWithinInput}
name="ios-search"
size={24}
/>
<TextInput
style={styles.AddEditInputs}
onChangeText={text => this.setState({ text })}
value={this.state.text}
/>
</View>
And the styles:
AddEditInputs: {
flex: 1,
height: 40,
borderWidth: 1,
},
IconWithinInput: {
padding: 10,
},
InputContainer: {
flexDirection: 'row',
},
I made the input borders like a rectangle to show you better what I meant to say.
The last design will be like this:
And as you may see, the input border is at the bottom of the icon too.
What else do I need to achieve what I need?
You cannot directly put icon on the textInput. What you can do is wrap the icon and textInput with the view with flexDirection set to row and provide the left padding to the icon so that it seems to appear as in textInput. If you want to do so you can use something like this
<View
style={{
flex: 1,
justifyContent: 'center',
alignItems: 'center'
}}>
<View style={{ flexDirection: 'row' }}>
<View style={{justifyContent: "center", marginRight: 5 }}>
<Image
source={{
uri: 'https://facebook.github.io/react-native/docs/assets/favicon.png',
}}
style={{ width: 10, height: 10 }}
/>
</View>
<TextInput placeholder="Enter your name" />
</View>
</View>
But my suggestion is to use the Input component of react-native-elements as it has leftIcon as props. You can find more information at here
<View style={{flex: 1, flexDirection: 'row'}}>
<Image
source={{uri: 'https://facebook.github.io/react-native/docs/assets/favicon.png'}}
style={{borderWidth: 1,width: 40, height: 40}}
/>
<TextInput
onChangeText={(text) => this.setState({text})}
value={this.state.text}
style={{borderWidth: 1, height: 40, borderColor: 'grey'}}
/>
<View>
Wrap the component with flex and provide width for the icon. You can set the icon by having some wrapper around since it can not be included inside textbox.
