java - Need some assistance trying to parse this JSON response from our backend server -


currently working on android app , need on how can go extracting subfields within responses field of json object:

pic of json object

currently doing following extract of other fields:

 jsonobject json = new jsonobject(response2);  int id = json.getint("id");  string desc = json.getstring("description");  jsonobject json2 = json.getjsonobject("owner");  string username = json2.getstring("username");

you need create logic parse data. every item json string in jsonobject created 

jsonobject json = new jsonobject(response2);

you're on right track you're doing. use corresponding methods available in jsonobject , jsonarray classes move through object.

start main object 

{                              // <-- main object (aka jsonobject json = new jsonobject(response2))     "id": 1,                   // pull id use json.getint("id");     "title": "some text here",  // pull title use json.getstring("title");     ...     "owner": {                 // here's logic part, owner itself, json object. must extract , parse through it.                                // pull "owner" json object, use jsonobject ownerobject = json.getjsonobject("owner");         "userid": 1,           // use ownerobject pull it's values. ownerobject.getint("userid");         "username": "testinguser",  // pull username use ownerobject.getstring("username");         ...     } ... }

if it's array, example:

"somejsonarray": [{ "id": 1, "username": "testinguser1" }, { "id": 2, "username": "testinguser2" }]

then call:

jsonarray somejsonarray = getjsonarray("somejsonarray"); // each object array. jsonobject object1 = somejsonarray.getjsonobject(0); jsonobject object2 = somejsonarray.getjsonobject(1);

or if array contains string, example:

"somekey": [ 23, 435, 123, 6345, 123 ]

then call:

jsonarray somekeyarray = getjsonarray("somekey"); (int = 0; < somekeyarray.length(); i++) {     // extract value.     int itemvalue = somekeyarray.getint(i); }

the data there, have parse it.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
