在React Native中实现对两个可拖动平面列表的搜索,可以通过以下步骤完成:
以下是一个简单的示例代码:
import React, { useState } from 'react';
import { View, TextInput, FlatList, PanResponder, Animated } from 'react-native';
const data = [
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' },
// ...
];
const SearchableDraggableList = () => {
const [searchKeyword, setSearchKeyword] = useState('');
const [listData, setListData] = useState(data);
const handleSearch = (keyword) => {
setSearchKeyword(keyword);
const filteredData = data.filter(item => item.name.includes(keyword));
setListData(filteredData);
};
const panResponder = PanResponder.create({
onStartShouldSetPanResponder: () => true,
onPanResponderMove: (e, gestureState) => {
// Update the position of the dragged item
// ...
},
onPanResponderRelease: () => {
// Save the updated list data
// ...
},
});
const renderItem = ({ item }) => (
<Animated.View {...panResponder.panHandlers}>
<View>
{/* Render the item */}
</View>
</Animated.View>
);
return (
<View>
<TextInput
placeholder="Search"
value={searchKeyword}
onChangeText={handleSearch}
/>
<FlatList
data={listData}
renderItem={renderItem}
keyExtractor={item => item.id.toString()}
/>
</View>
);
};
export default SearchableDraggableList;
这个示例代码实现了一个可拖动的平面列表,并且可以根据搜索框中的关键字对列表进行搜索过滤。你可以根据实际需求进行修改和扩展。
