类似于解析json数据的框架有很多，常用的就是Gson，使用起来特别的方便，同时，还拥有很好的可操作性，今天就来说说怎么用Gson去解析一个json数组。使用Gson之前，需要下载一个gson.jar的jar包。具体的自己去网上下载，有很多。

首先看看数据源

这个是一个比较具有代表性的json数据。先大体的分析一下数据，最外面的是一个json对象，里面有四个json数组。那么进行第一、步，先建立实体类，当然了，这么多的数据，不可能让我们一个个的去写，我们这里要引用一个工具，他会帮我生成实体类。
网址如下：http://www.bejson.com/json2javapojo/

这里为了方便，我就把这个数据放在了assets目录下，取名为text.txt 。

好了，数据源有了，实体类也建好了，那么就可以开始我们的编码了。首先是从assets取出数据，代码如下：

<code class="hljs cs has-numbering"><span class="hljs-keyword">try</span> {    String data;    InputStream <span class="hljs-keyword">is</span>;    <span class="hljs-keyword">is</span>=getResources().getAssets().open(<span class="hljs-string">"text.txt"</span>);            <span class="hljs-keyword">byte</span>[] b = <span class="hljs-keyword">new</span> <span class="hljs-keyword">byte</span>[<span class="hljs-keyword">is</span>.available()];            <span class="hljs-keyword">is</span>.read(b);            data = <span class="hljs-keyword">new</span> String(b);        } <span class="hljs-keyword">catch</span> (Exception e) {            <span class="hljs-comment">// TODO Auto-generated catch block</span>            e.printStackTrace();        }</code><ul class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li><li>6</li><li>7</li><li>8</li><li>9</li><li>10</li><li>11</li></ul><div class="save_code tracking-ad" style="display: none;" data-mod="popu_249"><a target=_blank target="_blank"><img src="http://static.blog.csdn.net/images/save_snippets.png" alt="" /></a></div>

这个data就是我们的json数据了，接下来就是实现解析的操作了。这里我写成了一个方法。具体代码如下：

<code class="hljs lasso has-numbering"><span class="hljs-comment">/*     * 解析数据     */</span>    <span class="hljs-keyword">public</span> <span class="hljs-literal">void</span> analysisData(<span class="hljs-built_in">String</span> <span class="hljs-built_in">data</span>) {        try {            <span class="hljs-comment">// Type listType = new TypeToken<List<Root>>() {</span>            <span class="hljs-comment">// }.getType();</span>            oList <span class="hljs-subst">=</span> <span class="hljs-literal">new</span> ArrayList<span class="hljs-subst"><</span><span class="hljs-built_in">Map</span><span class="hljs-subst"><</span><span class="hljs-built_in">String</span>, Object<span class="hljs-subst">>></span>();
