import React, {Component } from 'react';
import {
    StyleSheet,
    View,
    Text,
    Image,
    AlertIOS
} from 'react-native';

import ImagePicker from 'react-native-image-picker'
import NavigationBar from './NavigationBar'


//图片选择器参数设置
const options = {
    title: '请选择图片来源',
    cancelButtonTitle:'取消',
    takePhotoButtonTitle:'拍照',
    chooseFromLibraryButtonTitle:'相册图片',
    customButtons: [
        {name: '自定义', title: '自定义图片'},
    ],
    storageOptions: {
        skipBackup: true,
        path: 'images'
    }
};

export default class ImagePickerExample extends Component {

    constructor(props) {
        super(props);
        this.state = {
            avatarSource: null
        };
    }

    render(){

        return(
            
                

                选择照片
                
            
        );
    }

    doChoose(){

        ImagePicker.showImagePicker(options,(response)=>{

            if(response.didCancel) {
                console.log('用户取消了选择！');
            } else if (response.error) {
                alert("ImagePicker发生错误：" + response.error);
            } else if (response.customButton){
                alert("自定义按钮点击：" + response.customButton)
            } else {
                let source = {uri:response.uri};

                this.setState({
                    avatarSource:source
                });
            }

        });
    }
}


const styles = StyleSheet.create({

    container:{
        flex:1
    },

    image:{
        paddingTop:10,
        height:198,
        width:300,
        alignSelf:'center',
    },

    item:{

        marginTop:10,
        marginLeft:5,
        marginRight:5,
        height:30,
        borderWidth:1,
        padding:6,
        borderColor:'#ddd',
        textAlign:'center'
    },
});

3 直接启动相机或访问相册
