谁能告诉我如何通过 Json Array 或 Json Object 获取数据？在这里我也放了 url，我把我尝试过的所有数据都放入了一个变量中......这是我想要搜索的 src 名称对象，如下所示：http://i.ytimg.com/vi/cpqLJrFNBSY/0.jpg

首先，您的 JSON 响应无效，其次

你的代码行，

 jArray=jObject.getJSONArray("Guru");

您的回复中没有名为“Guru”的元素。

理想的方式应该是，

String jsonItem = JSONObject.getJSONArray("Array Name").getString("string name");

您可以使用此链接来验证您的 json 的有效性并查看树结构。

这是您的解决方案，

String href = JSONResponse.getJSONObject("feed").getJSONArray("entry").getJSONObject("0").getJSONArray("link").getJSONObject("0").getString("href");

对于其他值，您可以以相同的方式解析树。希望这可以帮助。

这是您的 j-son 链接获取标题的解决方案。这样您可以获得 href 和您想要的所有内容。

看一下这个：

String str = "<assign your json string>"
        try {
            JSONObject jObject=new JSONObject(str);
            jObject = jObject.getJSONObject("feed");
            JSONObject jObject1 = jObject.getJSONObject("title");
            Log.d("$t==", jObject1.getString("$t"));
            Log.d("type==", jObject1.getString("type"));
            JSONArray jArrayObject = new JSONArray(jObject.getString("link"));
            for (int i = 0; i<jArrayObject.length(); i++) {
                Log.d("href==", jArrayObject.getJSONObject(i).getString("href").toString());
            }
            JSONArray jArrayObject5 = new JSONArray(jObject.getString("entry"));
            for (int i = 0; i<jArrayObject5.length(); i++) {
                JSONObject jObject3 = jArrayObject5.getJSONObject(i).getJSONObject("title");
                Log.d("$t==", jObject3.getString("$t"));
                Log.d("type==", jObject3.getString("type"));
                JSONArray jArrayObject6 =  new JSONArray(jArrayObject5.getJSONObject(i).getString("link").toString());
                for (int j = 0; j<jArrayObject6.length(); j++) {
                    Log.d("href==", jArrayObject6.getJSONObject(j).getString("href").toString());
                }

            }
        } catch (Exception e) {
