Thank you so much to @Code in another answer. I can read any JSON file thanks to your code. Now, I'm trying to organize all the elements by levels, for could use them!

I was working with Android reading a JSON from an URL and the only I had to change was the lines

<code>Set&lt;Object&gt; set = jsonObject.keySet(); 
Iterator&lt;Object&gt; iterator = set.iterator();</code>

for

<code>Iterator&lt;?&gt; iterator = jsonObject.keys();</code>

I share my implementation, to help someone:

<pre><code>public void parseJson(JSONObject jsonObject) throws ParseException, JSONException {

 Iterator&lt;?&gt; iterator = jsonObject.keys();
 while (iterator.hasNext()) {
 String obj = iterator.next().toString();

 if (jsonObject.get(obj) instanceof JSONArray) {
 //Toast.makeText(MainActivity.this, "Objeto: JSONArray", Toast.LENGTH_SHORT).show();
 //System.out.println(obj.toString());
 TextView txtView = new TextView(this);
 txtView.setText(obj.toString());
 layoutIzq.addView(txtView);
 getArray(jsonObject.get(obj));
 } else {
 if (jsonObject.get(obj) instanceof JSONObject) {
 //Toast.makeText(MainActivity.this, "Objeto: JSONObject", Toast.LENGTH_SHORT).show();
 parseJson((JSONObject) jsonObject.get(obj));
 } else {
 //Toast.makeText(MainActivity.this, "Objeto: Value", Toast.LENGTH_SHORT).show();
 //System.out.println(obj.toString() + "\t"+ jsonObject.get(obj));
 TextView txtView = new TextView(this);
 txtView.setText(obj.toString() + "\t"+ jsonObject.get(obj));
 layoutIzq.addView(txtView);
 }
 }
 }
}
</code></pre>

I have JSON object as follows:

<pre><code>member = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";
</code></pre>

In Java I want to parse the above json object and store the values in an arraylist.

I am seeking some code through which I can achieve this.

Parsing JSON Object in Java

Android

JSON

Java

我有如下的JSON对象：member = "{interests : [{interestKey:Dogs}, {interestKey:Cats}]}";在Java中，我想解析上面的json对象，并将值存储在一个数组列表中。我正在寻找一些代码，通过它我可以实现这一点。
