<h1>React-Native入门指南</h1>
<h2>第4篇React-Native布局实战</h2>
<pre><code>前辈教导我们,掌握一门新技术的最快方法是练习。因此,我找了下比较有爱,暖气的界面。当然不是给美团打广告了,只是觉得页面蛮清新的。下面就是要显示的效果:
</code></pre>
<p><img src="pic/4_1.png" alt="美团" /></p>
<pre><code>第三篇文章基本上对React-Native的布局基本上有个大致的认识,现在开工吧。总体上,该页面分三个部分:(1)我们约会吧及其右边3栏;(2)1元吃大餐及其底下的4栏;(3)红火来袭的三栏。
</code></pre>
<h4>一、实现第一部分</h4>
<pre><code>1、首先,我们创建一个项目
现在我们需要创建一个React-Native的项目,因此可以按照下面的步骤:
打开终端,开始React-Native开发的旅程吧。
(1)安装命令行工具(已经安装了就不用再安装了):sudo npm install -g react-native-cli
(2)创建一个空项目:react-native init HelloWorld
(3)找到创建的HelloWorld项目,双击HelloWorld.xcodeproj即可在xcode中打开项目。xcodeproj是xcode的项目文件。
(4)在xcode中,使用快捷键cmd + R即可启动项目。
2、清除其余多余的代码,剩下的代码如下:
/**
* 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 (
&lt;View&gt;&lt;/View&gt;
);
}
});
var styles = StyleSheet.create({
});
AppRegistry.registerComponent('HelloWorld', () =&gt; HelloWorld);
3、此时,除了闪屏外,看到应该是空白的页面。开工,分析页面:
(1)大致有4个板块
(2)先是左右两栏(1/3和2/3);后是上下两栏(1/2)。我们先用View组件布局。
</code></pre>
<p><img src="pic/4_2.png" alt="美团" /></p>
<pre><code>4、完成初步布局
看如下代码,应该很清楚了,View里面嵌入并列的两栏。
</code></pre>
<p><img src="pic/4_3.png" alt="美团" /></p>
<pre><code>实现效果如下:
</code></pre>
<p><img src="pic/4_4.png" alt="美团" /></p>
<pre><code>5、添加内部图片和文字
其实做这种布局,还是有很多的细节,粗糙的效果如下,这块代码暂时不贴了,最后一并贴出来:
</code></pre>
<p><img src="pic/4_5.png" alt="美团" /></p>
<h4>二、按照第一部分原理,完成整个页面</h4>
<pre><code>完成的效果如下:
</code></pre>
<p><img src="pic/4_6.png" alt="美团" /></p>
<pre><code>整个代码如下:
/**
* Sample React Native App
* https://github.com/facebook/react-native

'use strict';
var React = require('react-native');
var {
AppRegistry,
