React Native 图片选择器组件for Android , 基于react-native-image-crop-picker

import React, { useState } from 'react';
import { View, Button, StyleSheet, Image, Platform } from 'react-native';
import ImagePicker from 'react-native-image-crop-picker';
 
const ImagePickerComponent = () => {
  const [selectedImage, setSelectedImage] = useState(null);
 
  const pickImage = () => {
    const options = {
      mediaType: 'photo',
      ...Platform.select({
        ios: {
          allowsEditing: true,
        },
      }),
    };
 
    ImagePicker.openPicker(options)
      .then((image) => {
        const { path, uri, width, height } = image;
        setSelectedImage({ path, uri, width, height });
      })
      .catch(e => console.log(e));
  };
 
  return (
    <View style={styles.container}>
      <Button title="选择图片" onPress={pickImage} />
      {selectedImage && <Image source={{ uri: selectedImage.uri }} style={styles.image} />}
    </View>
  );
};
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  image: {
    width: 200,
    height: 200,
    marginTop: 20,
  },
});
 
export default ImagePickerComponent;

这段代码展示了如何在React Native应用中使用react-native-image-crop-picker库来实现一个简单的图片选择器组件。用户点击按钮后，会打开系统的图片库或相机，选择并裁剪图片，然后将选定的图片显示在界面上。
