前言

React Native出来一年多了，受到各大开发人员的喜爱，但是由于只是专注于View层的开发，因此在很多深层次上还需要结合原生app做一定的兼容，还有就是现在好多控件，如Android中已是系统的控件的sidemenu、checkbox、gridview等，这些在react native中 系统是没有给我们提供的，这时候就借助了第三方开源的力量。
那么我们今天说说在React Native项目开发中常见的一些第三方库。

常见的第三方库

组件篇

CheckBox（多选按钮）

react-native-check-box CheckBox
基本用法：

 <CheckBox
     style=
     onClick={()=>this.onClick(data)}
     isChecked={data.checked}
     leftText={leftText} />;

当然我们也可以自定义样式，主要是对选中和未选中的样式做修改：

renderCheckBox(data) {
    var leftText = data.name;
    return (
        <CheckBox
            style=
            onClick={()=>this.onClick(data)}
            isChecked={data.checked}
            leftText={leftText}
            checkedImage={<Image source={require('../../page/my/img/ic_check_box.png')} style={this.props.theme.styles.tabBarSelectedIcon}/>}
            unCheckedImage={<Image source={require('../../page/my/img/ic_check_box_outline_blank.png')} style={this.props.theme.styles.tabBarSelectedIcon}/>}
        />);
}

RadioButton（单选按钮）

react-native-flexi-radio-button
使用也很简单，就是在中嵌套下就行：

 <RadioGroup
                   onSelect = {(index, value) => this.onSelect(index, value)}
                >
                     <RadioButton value={'item1'} >
                         <Text>This is item #1</Text>
                     </RadioButton>

                    <RadioButton value={'item2'}>
                         <Text>This is item #2</Text>
                     </RadioButton>

                     <RadioButton value={'item3'}>
                         <Text>This is item #3</Text>
                    </RadioButton>
                </RadioGroup>

sidemenu （侧滑栏）

react-native-side-menu
使用：

<SideMenu menu={menu}>
        <ContentView/>
      </SideMenu>

splashscreen

react-native-splash-screen
使用也很简单，就是添加一个闪屏的xml

imagepicker

这个组件帮助我们选取图片和调用相机等，这个组件同时支持photo和video，也就是照片和视频都可以用这个组件实现。
用法：

 import ImagePickerManager from ‘NativeModules‘;

var options = {
  title: ‘Select Avatar‘, // 选择器的标题，可以设置为空来不显示标题
  cancelButtonTitle: ‘Cancel‘,
  takePhotoButtonTitle: ‘Take Photo...‘, // 调取摄像头的按钮，可以设置为空使用户不可选择拍照
  chooseFromLibraryButtonTitle: ‘Choose from Library...‘, // 调取相册的按钮，可以设置为空使用户不可选择相册照片
  customButtons: {
    ‘Choose Photo from Facebook‘: ‘fb‘, // [按钮文字] : [当选择这个按钮时返回的字符串]
  },
  mediaType: ‘photo‘, // ‘photo‘ or ‘video‘
  videoQuality: ‘high‘, // ‘low‘, ‘medium‘, or ‘high‘
  durationLimit: 10, // video recording max time in seconds
  maxWidth: 100, // photos only默认为手机屏幕的宽，高与宽一样，为正方形照片
  maxHeight: 100, // photos only
  allowsEditing: false, // 当用户选择过照片之后是否允许再次编辑图片
};

ImagePickerManager.showImagePicker(options, (response) => {
  console.log(‘Response = ‘, response);

  if (response.didCancel) {
    console.log(‘User cancelled image picker‘);
  }
  else if (response.error) {
    console.log(‘ImagePickerManager Error: ‘, response.error);
  }
  else if (response.customButton) {
    // 这是当用户选择customButtons自定义的按钮时，才执行
    console.log(‘User tapped custom button: ‘, response.customButton);
  }
  else {
    // You can display the image using either data:

    if (Platform.OS === ‘android‘) {
        source = {uri: response.uri, isStatic: true};
    } else {
        source = {
            uri: response.uri.replace(‘file://‘, ‘‘),
            isStatic: true
        };
    }

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

然后在页面展示的时候：

<Image source={this.state.avatarSource} style={styles.uploadAvatar} />

说到这里，我们要说一下另一个控件picker

picker-Android

Picker就是ReactNative界的Spinner,其常用的属性有：

• onValueChange 这个方法在方法在选择Picker某一项时调用 可传两个参数 选择的value和position
• selectedValue 这个属性是选择的值
• enabled 设置是否可点击 Android属性
• mode 设置样式 Android属性 dropdown下拉样式和dialog弹窗样式 默认是dialog
• prompt 设置Picker标题 Android属性 并且只有是mode为dialog才会显示
• itemStyle 设置每一项的样式 iOS属性

用法：

/**
 * Created by Administrator on 2016/9/7.
 */
import React, {Component} from 'react';
import {
    AppRegistry,
    View,
    Picker,

} from 'react-native';

class PickerG extends Component {

    constructor(porp) {
        super(porp);
        this.state= {
            selectedValue: ''
        }
    }

    render() {
        return (
            <Picker
                //Picker样式 dialog弹窗样式默认  dropdown显示在下边
                // mode = {'dropdown'}
                //显示选择内容
                selectedValue={this.state.selectedValue}
                //选择内容时调用此方法
                onValueChange={(value)=>this.setState({selectedValue: value})}
                //设置Title 当设置为dialog时有用
                prompt={'请选择'}
            >
                <Picker.Item label='Android' value='android'/>
                <Picker.Item label='IOS' value='ios'/>
                <Picker.Item label='ReactNative' value='reactnative'/>
            </Picker>
        )
    }
}

module.exports = PickerG;

easy-toast

react-native-easy-toast
这个组件兼容了Android和iOS的toast,使用也很简单。
用法：

render() {
         return (
             <View style={styles.container}>
                 ...
                 <Toast ref="toast"/>
             </View>
         );
 }

最后在需要调用的地方：

this.refs.toast.show('hello world!');
