Question

Java代码看起来像下面; 在这里，我想要在活动中显示要显示的字符串所以，任何人都可以帮助我从JSONArray中找到结果字符串

try {
JSONArray productJsonArray = new JSONArray(result);
int count = productJsonArray.length();
if (count != 0) {
for (int i = 0; i < productJsonArray.length(); i++) {
JSONObject productObject = productJsonArray
                .getJSONObject(i);
String pID = productObject.getString("ID");
String pTitle = productObject.getString("title");
String pSDesc = productObject.getString("content");
String pImgSrc = productObject
                                .getJSONArray("featured_image")
                                .optJSONObject(0).getString("source");
NewsModel model = new NewsModel();
        model.setName(pTitle);
        model.setDesc(pSDesc);
        model.setId(pID);
        model.setImageName(pImgSrc);
newsArrayList.add(model);
}

这是JSON Rsult：

[2]
        0:  {
        ID: 216
        title: "New Farcry 4 release"
        status: "publish"
        modified_gmt: "2014-09-24T07:15:18"
        meta: {...}-
        featured_image: {
            ID: 217
            title: "Far-Cry-2-1422"
            status: "inherit"
            type: "attachment"

所以我想知道如何处理这个来从这个JSOn结果中获取源名称

Answer 1

featured_image不是数组而是对象。

更改行

String pImgSrc = productObject.getJSONArray("featured_image").optJSONObject(0).getString("source");

到

String pImgSrc = productObject.getJSONObject("featured_image").getString("source");

我正在处理wordpress后端服务，我想获得JSONArray结果
