If you don't already have a JSONArray object, call

<pre><code>JSONArray jsonArray = new JSONArray(jsonArrayString);
</code></pre>

Then simply loop through that, building your own array. This code assumes it's an array of strings, it shouldn't be hard to modify to suit your particular array structure.

<pre><code>List&lt;String&gt; list = new ArrayList&lt;String&gt;();
for (int i=0; i&lt;jsonArray.length(); i++) {
 list.add( jsonArray.getString(i) );
}
</code></pre>

blocks|key|1182134|text|尝试使用Jackson或GSON，而不是使用捆绑在一起的org.json库，这是一行程序。与杰克逊，f.ex：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1182135|List<String>+list+=+new+ObjectMapper().readValue(json,+List.class);

Instead of using bundled-in <code>org.json</code> library, try using Jackson or GSON, where this is a one-liner. With Jackson, f.ex:

I know that the question was for <code>Java</code>. But I want to share a possible solution for <code>Kotlin</code> because I think it is useful.

With Kotlin you can write an extension function which converts a <code>JSONArray</code> into an native (Kotlin) array:

<pre><code>fun JSONArray.asArray(): Array&lt;Any&gt; {
 return Array(this.length()) { this[it] }
}
</code></pre>

Now you can call <code>asArray()</code> directly on a <code>JSONArray</code> instance.
