How to Show Modal on half of screen and not the full screen-CodePudding

I am trying to create a Modal in react native so that when i click the transfer button, it prompts for a user password to complete the transaction. The challenge i have is that, it does not work as expected.

The screen looks thus :

after the modal has been triggered by clicking the transfer button the modal covers the whole screen like so

honestly, i dont know what and where to start from.

My code is looking thus :

import {
  ImageBackground,
  Modal,
  ScrollView,
  StyleSheet,
  Text,
  TextInput,
  TouchableOpacity,
  View,
} from 'react-native';
import {Picker} from '@react-native-picker/picker';
import React, { useState } from 'react';
import { useNavigation } from '@react-navigation/native';

const LocalPayments = () => {
  const navigation = useNavigation();
  const [modalVisible, setModalVisible] = useState(false);

  return (
    <View style={styles.container}>
      <View style={styles.space} />
      <ScrollView
        contentContainerStyle={{
          justifyContent: 'space-between',
          alignItems: 'center',

        <ImageBackground
          source={{
            uri: 'asset:/logo/bg.JPG',
          }}
          imageStyle={{borderRadius: 6}}
          style={{
            top: -30,

CodePudding user response：

Use top and height to control Modal position. Something like this would work:

<Modal
  animationType="slide"
  transparent={true}
  visible={modalVisible}>
  <View style={styles.modal}>
    <Button
      onPress={() => setModalVisible(!modalVisible)}
      title="Hide modal"/>
  </View>
</Modal>

const styles = StyleSheet.create({
  modal: {
    top: '50%',
    height: '50%',
...
  }
});
