解析 JSON 的最佳方法是使用GSON。你要做的是
- 下载 GSON jar 并添加到您的构建路径
- 现在创建代表 JSON 数据结构的类
- 仅在一行中解析数据。GSON 会为您做到这一点
只解析一行
String json = "{\"code\":200,\"error\":null,\"data\":{\"fixtures\":[{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-07-14\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64933\",\"awayteam\":\"Team 4\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-07-14\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64935\",\"hometeam\":\"Team 6\",\"awayteam_id\":\"64937\",\"awayteam\":\"Team 8\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-07-28\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64931\",\"awayteam\":\"Team 2\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-07-28\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64931\",\"awayteam\":\"Team 2\"}]}}";
MatchDetails matchDetails=new Gson().fromJson(json,MatchDetails.class);
System.out.println(matchDetails);
- 现在这
MatchDetails门课有Fixture Lists你需要的一切
- 通过访问夹具阵列
matchDetails.getData().getFixtures();

编辑具有功能的
编辑Fixtures类。sortFixtures如下使用它
String json = "{\"code\":200,\"error\":null,\"data\":{\"fixtures\":[{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-05-14\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64933\",\"awayteam\":\"Team 4\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-07-14\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64935\",\"hometeam\":\"Team 6\",\"awayteam_id\":\"64937\",\"awayteam\":\"Team 8\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-12-28\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64931\",\"awayteam\":\"Team 2\"},{\"kickoff\":\"15:00:00\",\"matchdate\":\"2012-01-28\",\"homescore\":null,\"awayscore\":null,\"attendance\":null,\"homepens\":null,\"awaypens\":null,\"division_id\":\"5059\",\"division\":\"Testing 1\",\"comp\":\"LGE\",\"location\":null,\"fixture_note\":null,\"hometeam_id\":\"64930\",\"hometeam\":\"Team 1\",\"awayteam_id\":\"64931\",\"awayteam\":\"Team 2\"}]}}";
