這裏是代碼: 我想根據時間和/或日期對它們進行排序: 它們已經被顯示,只是不按順序顯示。現在,我所擁有的是將json對象解析爲xml的代碼。我想要做的就是根據時間和/或日期來解析它們。下面的產品,其中有不同的日期和時間(2分鐘前,5分鐘前等)根據時間對json對象進行排序解析後的順序
try {
// Create the root JSONObject from the JSON string.
JSONObject jsonRootObject = new JSONObject(myjsonstring);
//Get the instance of JSONArray that contains JSONObjects
JSONArray jsonArray = jsonRootObject.getJSONArray("Postdetails");
//Iterate the jsonArray and print the info of JSONObjects
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
//Collections.sort(jsonValues);
String text = jsonObject.optString("number_of_likes").toString();
String minute = jsonObject.optString("min_ago").toString();
//float salary = Float.parseFloat(jsonObject.optString("salary").toString());
time += minute + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n";
data += text;
}
output.setText(data);
timeago.setText(time);
} catch (JSONException e) {
e.printStackTrace();
}
JSON文件JSON文件的例子:
{
"Postdetails": [
{
"min_ago": "2 min ago",
"number_of_likes": "63",
"number_of_comments": "92",
"date": "7 March 2017"
},
{
"min_ago": "5 min ago",
"number_of_likes": "72",
"number_of_comments": "123",
"date": "7 March 2017"
},
{
"min_ago": "9 min ago",
"number_of_likes": "123",
"number_of_comments": "9123",
"date": "10 March 2017"
},
{
"min_ago": "6 min ago",
"number_of_likes": "133",
"number_of_comments": "9123",
"date": "9 March 2017"
}
]
}
當你提取日期來訂購它們時,你已經解析了它。對你的應用程序有意義(或不知道你的用例)是在第一次解析之後緩存結果,可能是使用某種數據庫,但如果你的數據結構如此簡單,甚至可能會過度作爲這一個。 –
如何緩存結果? –
