How to create custom tabs in the centre of the screen in React Native - react-native

Question

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
style={styles.menuIcon}
source={MenuImage}
/>
</TouchableOpacity>
</View>
</View>
<View style ={styles.somestyles}>
<View style={styles.somestyles}>
<Text style= {styles.somestyles}>
Some Text
</Text>
<Text style= {styles.somestyles}>
Some Text
</Text>
<Text style= {styles.somestyles} >
<Text style= {styles.somestyles}>
Some Text
</Text>
<Text style ={styles.somestyles}>
Some Text
</Text>
</Text>
</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()}
}
}
