JSON字符串更新的TextView

我想提取從數據庫的JSON字符串和更新textview.My JSON字符串看起來是這樣的：
JSON字符串更新的TextView

[ 
    { 
     "meaning": "A boy or young man (often as a form of address)", 
     "examples": [ 
      "I read that book when I was a <em>lad</em>", 
      "come in, <em>lad</em>, and shut the door" 
     ] 
    }, 
    { 
     "meaning": "A group of men sharing recreational, working, or other interests", 
     "examples": [ 
      "she wouldn't let him go out with the <em>lads</em> any more" 
     ] 
    }, 
    { 
     "meaning": "A man who is boisterously macho in his behavior or actions, esp. one who is interested in sexual conquest", 
     "examples": [ 
      "Tony was a bit of a <em>lad</em>âalways had an eye for the women" 
     ] 
    }, 
    { 
     "meaning": "A stable worker (regardless of age or sex)", 
     "examples": [] 
    } 
]

我只是想提取「意義」。我怎樣才能做到這一點？

[** ** jsonlint（http://jsonlint.com/）是一個用於格式化JSON所以它是清晰的一個很好的工具。我繼續爲您格式化您的JSON。 – 2012-04-29 04:15:49

首先，這是一個JSON數組，其中包含許多meaning。

可以遍歷它這樣：

JSONArray jarr = new JSONArray(theJsonString); 
for (int i = 0; i < jarr.length(); ++i) 
{ 
    JSONObject jCell = jarr.getJSONObject(i); 
    String meaning = cell.getString("meaning"); 
    // set it as text? concatenate the strings? 
}

注：

爲了保持代碼清晰，我沒有處理異常，做在你的代碼。
瞭解更多關於JSON format。
以下類是android的一部分：JSONArray,JSONObject。
值得一讀的，下次你就不會要問:)
