我怎样才能parsing这个Android的JSON？
我想拉出用户块。 JSON结果总是会改变，有时会有4个用户返回，有时候会有10个。
{ "results": [ { "user": { "avatar_url_thumb": "http://avatars.stocktwits.com/production/9998/thumb-1270014645.png?1270014645", "avatar_url_medium": "http://avatars.stocktwits.com/production/9998/medium-1270014645.png?1270014645", "created_at": "2010-03-15T05:44:51Z", "following_count": 14, "updated_at": "2010-08-30T18:22:15Z", "id": 9998, "updates_count": 31, "avatar_url_large": "http://avatars.stocktwits.com/production/9998/large-1270014645.png?1270014645", "investor_relations": false, "last_name": "Reporter", "followers_count": 25, "recommended": false, "bio": "Apple News & AAPL Stock Analysis, visit Apple Digest blog link above", "login": "AppleReporter", "first_name": "Apple" } }, { "user": { "avatar_url_thumb": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_thumb.jpg", "avatar_url_medium": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_medium.jpg", "created_at": "2010-04-14T01:02:05Z", "following_count": 0, "updated_at": "2010-08-30T18:29:56Z", "id": 12924, "updates_count": 1, "avatar_url_large": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_large.jpg", "investor_relations": false, "last_name": "Shareholder", "followers_count": 0, "recommended": false, "bio": null, "login": "Imurphit", "first_name": "Apple" } }, { "user": { "avatar_url_thumb": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_thumb.jpg", "avatar_url_medium": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_medium.jpg", "created_at": "2010-04-17T20:52:09Z", "following_count": 0, "updated_at": "2010-08-30T18:31:23Z", "id": 13234, "updates_count": 0, "avatar_url_large": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_large.jpg", "investor_relations": false, "last_name": "Apple", "followers_count": 0, "recommended": false, "bio": null, "login": "apple11", "first_name": "John" } }, { "user": { "avatar_url_thumb": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_thumb.jpg", "avatar_url_medium": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_medium.jpg", "created_at": "2010-07-12T19:04:51Z", "following_count": 0, "updated_at": "2010-08-30T20:12:15Z", "id": 18691, "updates_count": 0, "avatar_url_large": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_large.jpg", "investor_relations": false, "last_name": "Smith", "followers_count": 0, "recommended": false, "bio": null, "login": "apple", "first_name": "Jacob" } }, { "user": { "avatar_url_thumb": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_thumb.jpg", "avatar_url_medium": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_medium.jpg", "created_at": "2010-07-13T17:06:27Z", "following_count": 0, "updated_at": "2010-08-30T20:12:30Z", "id": 18808, "updates_count": 3, "avatar_url_large": "http://api.stocktwits.comhttp://img.dovov.comdefault_avatar_large.jpg", "investor_relations": false, "last_name": "apple", "followers_count": 0, "recommended": false, "bio": null, "login": "applejames", "first_name": "James" } } ], "page": 1, "symbol": false, "per_page": 20, "response": { "status": 200 }, "total_pages": 1, "total_entries": 6 } 使用JSONObject
// Get some JSON from wherever String json = getJSONFromServer(); // Parse the JSON response into an object JSONObject object = new JSONObject(json); // Get the results array JSONArray users = object.getJSONArray("results"); for(int i = 0; i < users.length(); i++) { // Each element in the results array is a JSONObject with a single // property "user" which is a JSONObject that contains the user data JSONObject user = users.getJSONObject(i).getJSONObject("user"); // Do something with the user String firstName = user.getString("first_name"); }
