在react-native-modal dropdown中单击图像时显示下拉列表,可以通过以下步骤实现:
npm install react-native-modal react-native-image-picker
import React, { useState } from 'react';
import { View, TouchableOpacity, Image } from 'react-native';
import ModalDropdown from 'react-native-modal-dropdown';
import ImagePicker from 'react-native-image-picker';
const ImageDropdown = () => {
const [imagePath, setImagePath] = useState(null);
const selectImage = () => {
ImagePicker.showImagePicker({}, (response) => {
if (response.didCancel) {
console.log('User cancelled image picker');
} else if (response.error) {
console.log('ImagePicker Error: ', response.error);
} else {
setImagePath(response.uri);
}
});
};
return (
<View>
<TouchableOpacity onPress={selectImage}>
{imagePath ? (
<Image source={{ uri: imagePath }} style={{ width: 100, height: 100 }} />
) : (
<Image source={require('path/to/placeholder/image')} style={{ width: 100, height: 100 }} />
)}
</TouchableOpacity>
<ModalDropdown options={['Option 1', 'Option 2', 'Option 3']} />
</View>
);
};
export default ImageDropdown;
import React from 'react';
import { View } from 'react-native';
import ImageDropdown from './ImageDropdown';
const App = () => {
return (
<View>
<ImageDropdown />
</View>
);
};
export default App;
这样,当用户单击图像时,将会显示一个下拉列表,其中包含选项"Option 1"、"Option 2"和"Option 3"。用户可以从下拉列表中选择一个选项。
请注意,以上代码示例中的图像选择器和占位图像路径需要根据实际情况进行调整。此外,还可以根据需要自定义下拉列表的样式和选项。
