在Android中解析JSON数组而无需密钥 [英] Parse JSON Array without Key in Android

问题描述

我将如何在Android中解析类似于以下内容的数组?

How would I parse an array like the following in Android?

[
 5,
 10,
 15,
 20
]

如您所见，像其他示例数组一样，没有定义数组的键，例如:

As you can see, there is no key defining the array, like other example arrays have, such as this:

{
 "items": [
   5,
   10,
   15
   ]
}

对于第二个数组，我可以轻松地创建一个JSONObject并仅使用:

For the second array, I can easily make a JSONObject and just use:

JSONArray itemArray = jsonObject.getJSONArray("items")

但是，很明显，第一个数组没有键.那么，人们将如何处理呢?标准的Android库甚至可能吗?

But, as is obvious, there is no key for the first array. So how would one go about this? Is it even possible with standard Android libraries?

推荐答案

您是否尝试过这样做?

try {
    // jsonString is a string variable that holds the JSON 
    JSONArray itemArray=new JSONArray(jsonString);
    for (int i = 0; i < itemArray.length(); i++) {
        int value=itemArray.getInt(i);
        Log.e("json", i+"="+value);
    }
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
