Component - ViewPager

一个允许在子视图之间左右翻页的容器。每一个ViewPagerAndroid的子容器会被视作一个单独的页，并且会被拉伸填满ViewPagerAndroid。

注意所有的子视图都必须是纯View，而不能是自定义的复合容器。你可以给每个子视图设置样式属性譬如padding或backgroundColor。

关键代码： <View style={[styles.flex,{marginTop:45}]}> </View>

third-party lib

有很多开源的库支持左右翻页

1. React-Native-ViewPager

ViewPager and Indicator component for react-native on both android and ios.

ViewPager’s props is the same as ViewPagerAndroid.

2. react-native-scrollable-tab-view

This is probably my favorite navigation pattern on Android,

I wish it were more common on iOS! This is a very simple JavaScript-only implementation of it for React Native.

For more information about how the animations behind this work, check out the Rebound section of the React Native Animation Guide

异步网络数据

ReactNative不同于android的handler，AsyncTask。他是通过this.state 来触发UI更新。

RN中的网络请求：XMLHttpRequest， Fetch post get；

关键代码：

// get json data from network
fetchData(){
    fetch(REQ_URL)
        .then((response) => response.json())
        .then((responseData) => {
            this.setState({
                movies: responseData.movies
            });
        })
        .done();
}
