在React-Native中创建Action-Sheet/Bottom-Sheet样式的抽屉可以通过使用第三方库来实现。以下是一种常见的实现方式:
npm install react-native-actionsheet react-native-animations --save
import React, { useState } from 'react';
import { View, TouchableOpacity, Text } from 'react-native';
import ActionSheet from 'react-native-actionsheet';
import { createAnimation } from 'react-native-animations';
const DrawerExample = () => {
const [isDrawerVisible, setIsDrawerVisible] = useState(false);
// 显示抽屉
const showDrawer = () => {
setIsDrawerVisible(true);
};
// 隐藏抽屉
const hideDrawer = () => {
setIsDrawerVisible(false);
};
return (
<View>
<TouchableOpacity onPress={showDrawer}>
<Text>Show Drawer</Text>
</TouchableOpacity>
<ActionSheet
visible={isDrawerVisible}
onCancel={hideDrawer}
title={'Options'}
options={['Option 1', 'Option 2', 'Cancel']}
cancelButtonIndex={2}
onPress={(index) => {
if (index === 0) {
// 处理选项1的逻辑
} else if (index === 1) {
// 处理选项2的逻辑
}
hideDrawer();
}}
/>
</View>
);
};
export default DrawerExample;
const DrawerExample = () => {
// ...
const showDrawer = () => {
setIsDrawerVisible(true);
};
const hideDrawer = () => {
setIsDrawerVisible(false);
};
const slideInAnimation = createAnimation({
from: { translateY: 300 },
to: { translateY: 0 },
duration: 200,
});
const slideOutAnimation = createAnimation({
from: { translateY: 0 },
to: { translateY: 300 },
duration: 200,
});
return (
<View>
<TouchableOpacity onPress={showDrawer}>
<Text>Show Drawer</Text>
</TouchableOpacity>
<ActionSheet
visible={isDrawerVisible}
onCancel={hideDrawer}
title={'Options'}
options={['Option 1', 'Option 2', 'Cancel']}
cancelButtonIndex={2}
onPress={(index) => {
if (index === 0) {
// 处理选项1的逻辑
} else if (index === 1) {
// 处理选项2的逻辑
}
hideDrawer();
}}
containerStyle={{
position: 'absolute',
bottom: 0,
left: 0,
right: 0,
backgroundColor: 'white',
...slideInAnimation,
}}
overlayStyle={{
backgroundColor: 'rgba(0, 0, 0, 0.5)',
}}
onAnimationStart={() => {
if (isDrawerVisible) {
slideInAnimation.start();
} else {
slideOutAnimation.start();
}
}}
/>
</View>
);
};
export default DrawerExample;
通过上述步骤,你可以在React-Native中创建一个类似Action-Sheet/Bottom-Sheet样式的抽屉。你可以根据需要自定义样式和动画效果。请注意,以上示例中使用的是react-native-actionsheet和react-native-animations库,你可以根据实际需求选择其他适合的库来实现相似的效果。
