1) Swiper

Swipeable · React Native Gesture Handler

예시 코드를 보고 따라하면 됨! 아주 쉽다. 조금 쉽게 바꿔보면

import React from 'react';
import {Animated} from 'react-native';
import {RectButton} from 'react-native-gesture-handler';
import Swipeable from 'react-native-gesture-handler/Swipeable';
import {SSafeAreaView} from '../components/StyledComponents/Basic';
import {cWidth} from '../utils/constants';

export default () => {
  const renderLeftActions = (progress, dragX) => {
    const trans = dragX.interpolate({
      inputRange: [0, 50, 100, 101],
      outputRange: [-20, 0, 0, 1],
    });
    return (
      <RectButton
        style={{
          // flex: 1,
          width: cWidth,
          backgroundColor: 'cyan',
          justifyContent: 'center',
        }}
        onPress={console.log('Pressed')}>
        <Animated.Text
          style={[
            {
              color: 'black',
              fontSize: 16,
              transform: [{translateX: trans}],
            },
          ]}>
          Swiped!!
        </Animated.Text>
      </RectButton>
    );
  };
  return (
    <SSafeAreaView>
      <Swipeable renderLeftActions={renderLeftActions}>
        <RectButton
          style={{
            width: '100%',
            height: 80,
            backgroundColor: 'blue',
          }}
        />
      </Swipeable>
    </SSafeAreaView>
  );
};

 

renderLeftActions가 왼쪽으로 스와이프하면 보여지는 View를 그려준다!
