第4篇React-Native布局實戰(zhàn)

前輩教導我們,掌握一門新技術(shù)的最快方法是練習。因此,我找了下比較有愛,暖氣的界面。當然不是給美團打廣告了,只是覺得頁面蠻清新的。下面就是要顯示的效果:

第三篇文章基本上對React-Native的布局基本上有個大致的認識,現(xiàn)在開工吧??傮w上,該頁面分三個部分:(1)我們約會吧及其右邊3欄;(2)1元吃大餐及其底下的4欄;(3)紅火來襲的三欄。

一、實現(xiàn)第一部分

1、首先,我們創(chuàng)建一個項目
現(xiàn)在我們需要創(chuàng)建一個React-Native的項目,因此可以按照下面的步驟:
打開終端,開始React-Native開發(fā)的旅程吧。
(1)安裝命令行工具(已經(jīng)安裝了就不用再安裝了):sudo npm install -g react-native-cli
(2)創(chuàng)建一個空項目:react-native init HelloWorld
(3)找到創(chuàng)建的HelloWorld項目,雙擊HelloWorld.xcodeproj即可在xcode中打開項目。xcodeproj是xcode的項目文件。
(4)在xcode中,使用快捷鍵cmd + R即可啟動項目。

2、清除其余多余的代碼,剩下的代碼如下:
/**
* Sample React Native App
* https://github.com/facebook/react-native
*/
'use strict';

var React = require('react-native');
var {
    AppRegistry,
    StyleSheet,
    Text,
    View,
} = React;

var HelloWorld = React.createClass({
    render: function() {
        return (
            <View></View>
        );
    }
});
var styles = StyleSheet.create({

});

AppRegistry.registerComponent('HelloWorld', () => HelloWorld);

3、此時,除了閃屏外,看到應該是空白的頁面。開工,分析頁面:
(1)大致有4個板塊
(2)先是左右兩欄(1/3和2/3);后是上下兩欄(1/2)。我們先用View組件布局。

4、完成初步布局
看如下代碼,應該很清楚了,View里面嵌入并列的兩欄。

實現(xiàn)效果如下:

5、添加內(nèi)部圖片和文字
其實做這種布局,還是有很多的細節(jié),粗糙的效果如下,這塊代碼暫時不貼了,最后一并貼出來:

二、按照第一部分原理,完成整個頁面

完成的效果如下:

http://wiki.jikexueyuan.com/project/react-native-lesson/images/4_6.png" alt="美團" />

整個代碼如下:
/**
* Sample React Native App
* https://github.com/facebook/react-native
*/
'use strict';

var React = require('react-native');
var {
    AppRegistry,
    StyleSheet,
    Text,
    View,
    Image,
} = React;

var HelloWorld = React.createClass({
    render: function() {
        return (
            <View style={{}}>
