android - 如何在android中解析没有json对象标题的json数组？

Question

   [
    {
        "name":           "The Universe & The Earth"
      , "imagename":      "cat1.jpg"
      , "active":         "Y"
      , "createdon":      "1901-01-01"
      , "lastmodifiedon": "1901-01-01 00:00:00"
      , "description":    "Knowledge of Earth location in the universe has been shaped by 400 years of telescopic observations, and has expanded radically in the last century.\n"
      , "id":             "1"
    }
  , {
        "name":           "Life on Earth"
      , "imagename":      "cat2.jpg"
      , "active":         "Y"
      , "createdon":      "1901-01-01"
      , "lastmodifiedon": "1901-01-01 00:00:00"
      , "description":    "Over the last 3.7 billion years or so, living organisms on the Earth have diversified and adapted to almost every environment imaginable."
      , "id":             "2"
    }
]

这是我的 json 值。现在我想解析并显示在自定义 ListView 中我该如何 做这个？我关注了http://www.androidhive.info/2012/01/android-json-parsing-tutorial/这是链接，但无法实现。我怎样才能做到这一点？谁能告诉我？提前致谢。

Answer 1

这是一个 JSONArray 而不是 JSONObject - 要从中创建一个 JSONObject，请使用

JSONObject jsonObject = jsonArray.getJSONObject(0);

从这个 JSONArray 获取第一个 JSONObject。

如果你有多个 JSONObjects，使用这个:

JSONObject jsonObject;
for(int n = 0; n < jsonArray.length(); n++)
{
    jsonObject = jsonArray.getJSONObject(n);
}

获取值:

jsonObject.getString("name");
