如何从PhP服务器安卓应用程序获取JsonArray

我相信你需要时间来研究。看起来你才刚刚开始。

他们有很多方法可以做到这一点。

您可以随意使用Rest API或SOAP API。或者你可以在android上建立自己的http客户端，从web服务器请求和接收数据。

一切都好。

对于SOAP，您可以使用Ksoap2

对于实现Volley来说，这是最好的来源。

使用以下代码解析json数组

               JSONParser jParser = new JSONParser();
                JSONObject json = jParser.getJSONFromUrl(url);
                JSONArray jArrayVersion = json.getJSONArray("result");
                for (int j = 0; j < jArrayVersion.length(); j++) {
                    JSONObject items = jArrayVersion.getJSONObject(j);
                    String namesv = items.getString("name");
                    String message = items.getString("message");
                   }
