我想解析下面的json.However但我沒有得到我想要的結果。我不明白爲什麼有不匹配。org.json.JSONException在at org.json.JSON.typeMismatch

但我沒有得到顯示的標題。無所事事。從討論

您發佈的內容不是有效的JSON。給我們/將我們鏈接到您正在處理的整個文件版本。 – poss

這裏：http://pastebin.com/84iitz3v –

文件看起來像一個JsonArray，所以首先你應該將字符串提取到JSonArray，然後使用JSonObject作爲「顯示」對象。 – itwasntme

答：

訪問show對象JSONArray在JSONArray jsonArray = jsonObject.getJSONArray("show");會導致typeMismatch，因爲它是一個對象。

要循環儘管響應對象，並得到例如標題，我們可以使用

for (int i = 0; i < response.length(); i++){ 
    JSONObject wholeObject = response.getJSONObject(i); 
    JSONObject showObject = wholeObject.getJSONObject("show"); 
    String title = showObject.getString("title"); 
    Log.d("",title); 
}

併爲人們從谷歌絆這裏：基本規則objects和JSON arrays區分：對象在關閉{}，陣列關閉在[]（我們通常使用循環來通過陣列）
