Examples of org.json.JSONArray.optJSONObject()

org.json.JSONArray.optJSONObject()
Get the optional JSONObject associated with an index. Null is returned if the key is not found, or null if the index has no value, or if the value is not a JSONObject. @param index The index must be between 0 and length() - 1. @return A JSONObject value.

      jsonArray = jsonObject.optJSONArray("tweet");
    }
    if (jsonArray != null) {
      List<TweetInfo> tweets = new ArrayList<TweetInfo>();
      for (int i = 0; i < jsonArray.length(); i++) {
        tweets.add(TweetInfo.parse(jsonArray.optJSONObject(i)));
      }
      obj.tweets = tweets;
    }
    obj.tweetNum = Result.parseInteger(jsonObject.opt("tweetnum"));
    obj.verifyInfo = Result.toString(jsonObject.opt("verifyinfo"));
