Json解析代码是这样的
@Override
protected Void doInBackground(Void... arg0) {
News news = new News();
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String url = "http://api.steampowered.com/ISteamNews/GetNewsForApp/v0002/?appid=466560&count=3&maxlength=300&format=json";
String jsonStr = sh.makeServiceCall(url);
;
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONArray contacts = jsonObj.getJSONArray("appnews");
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
news.setTittle( c.getString("title"));
news.setContent(c.getString("content"));
news.setDate(c.getString("date"));
news.setFeed(c.getString("feedlabel"));
news.setUrl(c.getString("url"));
newsList.add(news);
}
} catch (final JSONException e) {
runOnUiThread(new Runnable() {
@Override
public void run() {
}
});
}
} else {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Couldn't get json from server",
Toast.LENGTH_LONG).show();
}
});
}
return null;
}
