Ovelay react native flatlist items - react-native

Guys why my flatlist items are not rendering over the succeeding text input. I can see my white background text input rendering over the flatlist items. I wan't to have the flatlist items over the text input.
const SearchScreen = () => {
return (
<SafeAreaView>
<View>
<TextInput
style={styles.textInput}
placeholder={placeholder}
value={place}
onChangeText={(str) => handlePlace(str)}/>
<FlatList style={styles.flatList}
data={data}
keyExtractor={item => item.place_google_id}
renderItem={({item}) => (
<View style={{backgroundColor: "#000"}}>
<Text style={{color: "#FFF"}}>{item.description}</Text>
</View>
)}
/>
</View>
<TextInput style={{backgroundColor: "white"}}/>
</SafeAreaView>
)
};
flatList: {
flex: 1,
left: 10,
position: "absolute",
right: 10,
top: 50,
}

you can add zIndex to your flatlist styles :
flatList: {
flex: 1,
left: 10,
position: "absolute",
right: 10,
top: 50,
zIndex:4 // add this
}
Hope it helps . feel free for doubts

Horizontal Flatlist Re-Render changes ListHeaderComponent

I'm banging my head on this one. I am using a horizontal flat list. And putting a view in ListHeaderComponent to act as padding. You can see it as a blue box in the first image below. That works great. Trouble is, when I refresh the flatlist from elsewhere in my app, the padding seems to break. See the blue box in image 2 below. Code below images. Any help appreciated.
OnLoad:
After props refresh:
<FlatList
ref={(ref) => { this.flatListRef = ref; }}
horizontal={true}
showsHorizontalScrollIndicator={false}
data={this.props.store.allBookData}
ListHeaderComponent={<View style={{ width: itemOffset / 2, height: 200, backgroundColor: 'blue' }}></View>}
ListFooterComponent={<View style={{ width: itemOffset /2 }}></View>}
renderItem={({ item }) =>(
<TouchableWithoutFeedback onPress={() => this.gotoBook(item)}>
<Animatable.View
animation={"fadeIn"}
easing={"ease-in-out"}
duration={320}
delay={240}
useNativeDriver={true}
style={[styles.bookItem, { width: itemWidth, height: itemHeight, marginTop: itemMarginTop, opacity: 1, marginRight: 24 }]}>
{/* cover */}
<View style={[styles.bookCover, { width: itemWidth, height: bookHeight, backgroundColor: global.setBookItemColor(item.color)}]}>
<View style={styles.bookBindingHolder}>
<View style={styles.bookBinding}></View>
</View>
<View style={styles.bookCoverPhotoHolder}>
<View style={styles.bookCoverPhoto}>
<FastImage style={styles.bookCoverFrame} resizeMode={'contain'} source={Images.coverFrameWithTape}/>
{(() => {
//display cover
if (item.cover == 'temp') {
//temp
return (<FastImage style={styles.bookCoverImg} resizeMode={'cover'} source={Images.tempCover} />)
}else{
//photo
return (
<FastImage
style={[styles.bookCoverImg, {opacity: 0.88}]}
resizeMode={'cover'}
source={{uri: item.cover}}>
</FastImage>
)
}
})()}
</View>
</View>
</View>
{/* title */}
<View style={styles.bookTitleHolder}>
<Text style={[global.TextStyles.h3, global.TextStyles.darkText, global.TextStyles.alignCenter]}>{item.title}</Text>
</View>
{/* count */}
<View style={styles.bookPhotoCountHolder}>
<View style={styles.bookPhotoCount}>
{(() => {
if (item.photoCount == global.maxPhotos){
var itemCount = 'Full'
}else{
var itemCount = item.photoCount + '/' + global.maxPhotos
}
return(
<Text style={[global.TextStyles.lightText, global.TextStyles.smallerLabel]}>{itemCount}</Text>
)
})()}
</View>
</View>
</Animatable.View>
</TouchableWithoutFeedback>
)}/>
It's hard to say where the problem comes from even though there's a good chance it comes from your itemOffset that you apply as width to your HeaderComponent.
However, I have the impression that you can make it easier to define paddings, instead of defining a header and footer component, you could simply apply paddings to the content of your list by passing to your list the props: contentContainerStyle
like that
<FlastList
...
contentContainerStyle={{
paddingHorizontal: itemOffset / 2
}}
/>
but I think you should look in your calcul of itemOffset

Last odd flatlist item stretches along screen

I'm displaying some data items with Flatlist in two columns. But when there is an odd item at the last place, it stretches all along the screen. I don't want that, how can I make it to take only %50 of screen space like even items? Thanks a lot.
CategoryGridTile Component:
return (
<View style={styles.PlaceItem}>
<TouchableCmp onPress={props.onSelect}>
<View>
<View style={{ ...styles.placeRow, ...styles.placeHeader }}>
<ImageBackground
source={{ uri: props.image }}
style={styles.bgImage}
>
<View style={styles.titleContainer}>
<Text style={styles.title} numberOfLines={2}>
{props.title}
</Text>
</View>
</ImageBackground>
</View>
</View>
</TouchableCmp>
</View>
)
}
const styles = StyleSheet.create({
PlaceItem: {
flex: 1,
height: 125,
width: '80%',
backgroundColor: '#f5f5f5',
borderRadius: 5,
overflow: 'hidden',
margin: 6
},
placeRow: {
flexDirection: 'row'
}
})
Screen:
const renderGridItem = itemData => {
return (
<CategoryGridTile
image={itemData.item.image}
title={itemData.item.title}
onSelect={() => {
props.navigation.navigate({
routeName: 'CategoryPlaces',
params: {
categoryId: itemData.item.title,
locationId: locations
}
})
}}
/>
)
}
return (
<FlatList
keyExtractor={(item, index) => item._id}
data={displayedCategories}
renderItem={renderGridItem}
numColumns={2}
/>
)
Changing PlaceItem flex: 1 to flex: 1/2 at CategoryGridTile component solved the problem.

React Native Flatlist zIndex not working with overflow: 'visible' on iOS

I'm trying to implement a bottom-up Flatlist on iOS. To do that; I had to reverse the items, flip the list and flip the list again. It works fine but when I try to use overflow: 'visible', it goes on top of everthing (including the StatusBar) and I cannot hide it.
The code of FlatList:
render() {
let data = renderMessages(this.props.comments, this.props.postId) //??
return (
<FlatList
ref="listRef"
data={data}
keyExtractor={this._keyExtractor}
renderItem={this._renderItem}
style={{ position: 'absolute', transform: [{ scaleY: -1 }], flexGrow: 0, overflow: 'visible', zIndex: -9999}}
onEndReached={this.onEndReached}
onEndReachedThreshold={0.01}
enableEmptySections={true}
onScrollBeginDrag={() => { this.onEndReachedCalledDuringScroll = false; }}
/>
)
}
Parent:
<View style={{ flex: 1, width: Dimensions.get('window').width }}>
<CommentList
count={this.props.commentCounter[post.id] || 10}
postId={post.id}
/>
</View>
Is there a way to fix that behaviour. I would really appreciate the help. Thank you.

How do i set a background image to custom DrawerNavigator in react-navigation

My issue is, that i want the image is overflowing the Drawer
and does not fit the view width
I use contentComponent to have a custom Drawer.
the answer in the link below shows kinda what i want to achieve.
The issue though is, that width and heigth are given in absolute
values. This won't be working for tablet, iphones and android phones.
Any ideas?
export default StyleSheet.create({

container: {
//marginTop: Metrics.navBarHeight,

right: 0,
bottom: 0,
opacity: 0.05,
backgroundColor: 'green'
// resizeMode: "stretch"
},
render () {
const { navigation } = this.props
return (
<View style={styles.container}>
<Image source={Images.drawerBackground} style={styles.drawerImage}/>
<ScrollView style={styles.contentContainer}>

React-Native: how to fill fullsize screen without explicit Width and Height?

I want to create a fullsize-screen with the child-view (a video player) that is rendered over the full size of the screen. I only get it work when i pass explicitly width and height to the component.
But i know that there is a property called "flex". In many tutorials they do something like "flex: 1", but for me it nowhere does what it is supposed to.
(For the sake of completeness, the video-player is not part of the question. I can also replace the <video> tag with <Image> or each other kind of view and get the same results)
render() {
const uri = this.props.uri
return (
<KeyboardAwareScrollView keyboardShouldPersistTaps="always" >
<TouchableWithoutFeedback onPress={RouterActions.pop}>
<Video source={{uri: uri}}
ref={(ref) => {
this.player = ref
}}
style={s.fullsize}
/>
</TouchableWithoutFeedback>
<TouchableOpacity onPress={RouterActions.pop} style={s.closeBtn}>
<Icon name="times-circle-o" size={20} color="white" />
</TouchableOpacity>
</KeyboardAwareScrollView>
)
}
My styles:
This is only working when i pass the width and height:
const s = StyleSheet.create({
fullsize: {
backgroundColor: 'black',
//flex: 1,
width: Dimensions.get('window').width,
height: Dimensions.get('window').height,
},
closeBtn: {
position: 'absolute',
left: 20,
top: 25,
},
});
I only tried out this one, but then the screen will be empty because of the -Component has a width and height of 0 each.
const s = StyleSheet.create({
fullsize: {
backgroundColor: 'black',
flex: 1, // this is not working
left: 0,
right: 0,
top: 0,
bottom: 0
},
});
I believe doing flex: 1 will make it take up all the space provided by it's parent element. In your case, none of your parent elements have any styling so try this out:
render() {
const uri = this.props.uri
return (
<View style={{ flex: 1 }}>
<TouchableWithoutFeedback style={{ flex: 1 }} onPress={RouterActions.pop}>
<Video source={{uri: uri}}
ref={(ref) => {
this.player = ref
}}
style={{ flex: 1 }}
/>
</TouchableWithoutFeedback>
<TouchableOpacity onPress={RouterActions.pop} style={s.closeBtn}>
<Icon name="times-circle-o" size={20} color="white" />
</TouchableOpacity>
</View>
)
}
