我amtrying做的是：

What I amtrying to do is:

for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject jsonObject = jsonArray.getJSONObject(i);
        System.out.println(jsonObject.getString("title"));
}

非常感谢你的帮助。

Thank you very much for your help.

推荐答案

看起来你是不是很挖得足够深，让您的数据。你有什么是含有多个阵列，其每一个包含一个对象的阵列。试试这个：

It looks like you aren't digging quite deep enough to get to your data. What you have is an array containing multiple arrays, each of which contains an object. Try this:

for (int i = 0; i < jsonArray.length(); i++) {
        JSONArray innerJsonArray = jsonArray.getJSONArray(i);
        JSONObject jsonObject = innerJsonArray.getJSONObject(0);
        System.out.println(jsonObject.getString("title"));
}
