A Modal allow to display a component on top of another and you can read more about it on this link (https://reactnative.dev/docs/modal).
import React, { useState } from "react";
import {
Alert,
Modal,
StyleSheet,
Text,
TouchableHighlight,
View
} from "react-native";
const App = () => {
const [modalVisible, setModalVisible] = useState(false);
return (
<View style={styles.centeredView}>
<Modal
animationType="slide"
transparent={true}
visible={modalVisible}
onRequestClose={() => {
Alert.alert("Modal has been closed.");
}}
>
<View style={styles.centeredView}>
<View style={styles.modalView}>
<Text style={styles.modalText}>Hello World!</Text>
<TouchableHighlight
style={{ ...styles.openButton, backgroundColor: "#2196F3" }}
onPress={() => {
setModalVisible(!modalVisible);
}}
>
<Text style={styles.textStyle}>Hide Modal</Text>
</TouchableHighlight>
</View>
</View>
</Modal>
<TouchableHighlight
style={styles.openButton}
onPress={() => {
setModalVisible(true);
}}
>
<Text style={styles.textStyle}>Show Modal</Text>
</TouchableHighlight>
</View>
);
};
const styles = StyleSheet.create({
centeredView: {
flex: 1,
justifyContent: "center",
alignItems: "center",
marginTop: 22
},
modalView: {
margin: 20,
backgroundColor: "white",
borderRadius: 20,
padding: 35,
alignItems: "center",
shadowColor: "#000",
shadowOffset: {
width: 0,
height: 2
},
shadowOpacity: 0.25,
shadowRadius: 3.84,
elevation: 5
},
openButton: {
backgroundColor: "#F194FF",
borderRadius: 20,
padding: 10,
elevation: 2
},
textStyle: {
color: "white",
fontWeight: "bold",
textAlign: "center"
},
modalText: {
marginBottom: 15,
textAlign: "center"
}
});
export default App;
