Is there a way to be able to interact with the background components when Modal is visible?

as the title states, I am attempting to implement a modal in such way that it only takes up some part of the screen so as to allow the user to be able to interact with some of the background components. For reference I am using the react-native-modal library. The current screen looks like this:
I would like to be able to interact with the icons in the header (both are already wrapped in Touchable components so already clickable). However when the Modal is visible I am unable to interact with those.
My implementation is as such:
<Modal
isVisible={showModal}
style={styles.modalContainer}
customBackdrop={<CustomBackdrop />}
onBackdropPress={() => setShowModal(false)}
animationIn="fadeInDown"
animationOut="fadeOutUp"
>
<View style={styles.container}>
<TouchableOpacity style={styles.itemContainer}>
<Text style={styles.label}>A</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.itemContainer}>
<Text style={styles.label}>B</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.itemContainer}>
<Text style={styles.label}>C</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.itemContainer}>
<Text style={styles.label}>D</Text>
</TouchableOpacity>
<TouchableOpacity
style={[
styles.itemContainer,
{ borderBottomLeftRadius: 16, borderBottomRightRadius: 16 },
]}
>
<Text style={styles.label}>E</Text>
</TouchableOpacity>
</View>
</Modal>
And my custom background looks like this:
<View
style={{
marginTop: hp("50%"),
flex: 1,
}}
>
<TouchableWithoutFeedback onPress={() => setShowModal(false)}>
<View
style={{ backgroundColor: "#000", height: hp("50%"), width: wp("100%") }}
/>
</TouchableWithoutFeedback>
</View>

Placement of text and toggle button

I want to place a text and a toggle button in such a manner that the Text should be there at flex-start and the toggle would be there at the flex end. I have come up with the following code :
<TouchableRipple onPress={() => { }}>
<View style={{flexDirection: 'row'}}>
<Text style={{ fontSize: 18, fontWeight: "bold" }}>
<FontAwesome5 name="bookmark" size={16} /> Booked
</Text>
<View pointerEvents="none" style={{justifyContent: "flex-end"}}>
<Switch value={true} />
</View>
</View>
</TouchableRipple>
But the view is coming as follows:
How can I put the same at the end ?
Any help would be appritiated.
Here try this
<TouchableRipple onPress={() => { }}>
<View style={{flexDirection: 'row'}}>
<View style={{flex:1}}> //wrap Text inside view with flex 1
<Text style={{ fontSize: 18, fontWeight: "bold" }}>
<FontAwesome5 name="bookmark" size={16} /> Booked
</Text>
</View>
<View pointerEvents="none" style={{flex:1,justifyContent: "flex-end"}}> //add flex 1 here
<Switch value={true} />
</View>
</View>
</TouchableRipple>

ScrollView isn't appering

I was messing with my code and suddenly the ScrollView decided to disappear.
For some reason, the ScrollView works "properly" inside the Character bar View
but when it is inside of the base View it just isn't there.
export default class CharacterSheet extends Component {
render() {
return (
<View style={{flex:1}}>
<View style={styles.TopBar}>
<View>
</View>
</View>
<View style={{flex:1}}>
<View style={styles.CharacterBar}>
</View><View style={styles.Base}>
<ScrollView style={styles.scroll}>
<View style={{paddingTop:72}}>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>e</Text>
</View>
<View style={styles.spellsBox}>
<Text>a</Text>
</View>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
</View>
</ScrollView>
</View>
<Animated.View style={styles.CharacterStatsBar}>
</Animated.View>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
CharacterBar:{
height:72,
backgroundColor:'#242527'
},
CharacterStatsBar:{
position:'absolute',
top: 72,
left: 0,
right: 0,
height:72,
backgroundColor:'#404040',
borderBottomWidth:2,
borderBottomColor:'#c53131',
borderTopWidth:1,
borderTopColor:'#838383',
},
Base:{
flex:1,
backgroundColor:'#fff',
},
scroll:{
width:'95%',
alignSelf:'center'
},
spellsBox:{
height:80,
marginTop:10,
paddingVertical:10,
borderColor:'#777',
borderWidth:3,
justifyContent:'center'
}
});
I'm trying to run this in an android device
this problem is pretty annoying and is stressing me a little bit.
Try Like this , don't wrap ScrollView inside multiple Views.
<View style={{flex:1}}>
<View style={styles.TopBar}>
<View>
</View>
</View>
<ScrollView style={styles.scroll}>
<View style={{paddingTop:72}}>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>e</Text>
</View>
<View style={styles.spellsBox}>
<Text>a</Text>
</View>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>Hi</Text>
</View>
<View style={styles.spellsBox}>
<Text>byee</Text>
</View>
</View>
</ScrollView>
</View>

View is not showing on screen

I have the code below:
<ImageBackground style={{flex:1, width: null, height: null}} source={require('../img/bg.png')}>
<View style={{flex:1, backgroundColor:'red'}}>
</View>
<View style={{flex:1, backgroundColor:'yellow'}}>
<Text style={{fontSize:40}}>RESULTADOS</Text>
</View>
<View style={{flex:6, backgroundColor:'red'}}>
<ScrollView style={{flex:1, backgroundColor:'blue'}}>
<View style={{flex:1, backgroundColor:'white'}}>
//THIS NOT SHOW
</View>
<View style={{flex:1, backgroundColor:'green'}}>
//THIS NOT SHOW
</View>
</ScrollView>
</View>
</ImageBackground>
The View whit background color white and green is not showing on the screen.
Anybody help?
TheScrollView component has a special prop to set style for the content. It's the contentContainerStyle
Instead of using
<ScrollView style={{flex:1, backgroundColor:'blue'}}>
Just use
<ScrollView contentContainerStyle={{flex:1, backgroundColor:'blue'}}>
