Suppose we have a json ：
{
"total_count": 132,
"page_size": 2,
"page_index": 1,
"twitter_posts": [
{
"created_on": 1465935152,
"tweet_id": 210462857140252672,
"tweet": "Along with our new #Twitterbird, we've also updated our Display Guidelines",
"url": "https://twitter.com/twitterapi/status/210462857140252672"
},
{
"created_on": 1465995741,
"tweet_id": 735128881808691200,
"tweet": "Information on the upcoming changes to Tweets is now on the developer site",
"url": "https://twitter.com/twitterapi/status/735128881808691200"
}
]
}We can parse this array into a Custom Tweets (tweets list container) object manually, but it is easier to do it with fromJson method:
Gson gson = new Gson();
String jsonArray = "....";
Tweets tweets = gson.fromJson(jsonArray, Tweets.class);Suppose we have two classes below:
class Tweets {
@SerializedName("total_count")
int totalCount;
@SerializedName("page_size")
int pageSize;
@SerializedName("page_index")
int pageIndex;
// all you need to do it is just define List variable with correct name
@SerializedName("twitter_posts")
List<Tweet> tweets;
}
class Tweet {
@SerializedName("created_on")
long createdOn;
@SerializedName("tweet_id")
String tweetId;
@SerializedName("tweet")
String tweetBody;
@SerializedName("url")
String url;
}and if you need just parse a json array you can use this code in your parsing:
String tweetsJsonArray = "[{.....},{.....}]"
List<Tweet> tweets = gson.fromJson(tweetsJsonArray, new TypeToken<List<Tweet>>() {}.getType());
