帶有Android的JSONArrays

Question

我有一個可以解析JSONArray的程序，但前提是jsonarray中包含jsonobject，例如：

"weather":[{"id":803,"main":"Clouds","description":"broken clouds","icon":"04d"}]

我正在嘗試解析一個像這樣的jsonarray：

"messages":["This is a demo message.  Enjoy!","Another demonstration message stored in JSON format.","JSON stands for JavaScript Object Notation (I think)","hello"]

所以我想知道的是，如何轉換現在可以解析這種json數組的代碼。 這是我當前的解析jsonarray的代碼：

 @Override
    protected Boolean doInBackground(String... urls) {
        try {

            //------------------>>
            HttpGet httppost = new HttpGet(urls[0]);
            HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = httpclient.execute(httppost);

            // StatusLine stat = response.getStatusLine();
            int status = response.getStatusLine().getStatusCode();

            if (status == 200) {
                HttpEntity entity = response.getEntity();
                String data = EntityUtils.toString(entity);


                JSONObject jsono = new JSONObject(data);
                JSONArray jarray = jsono.getJSONArray(/*"actors"*/"weather");


                for (int i = 0; i < jarray.length(); i++) {
                    JSONObject object = jarray.getJSONObject(i);

                    Actors actor = new Actors();

                    actor.setName(object.getString("id"));


                    actorsList.add(actor);

                }

如果您需要查看更多代碼，請詢問，我們將很樂意提供。 謝謝。

您可以這樣：

if (status == 200)
    {
        HttpEntity entity = response.getEntity();
        String data = EntityUtils.toString(entity);

        JSONObject jsono = new JSONObject(data);
        JSONArray jarray = jsono.getJSONArray("messages");
        for (int i = 0; i < jarray.length(); i++)
        {
            String message = jarray.getString(i);
        }
    }
