Клас для ArrayList & ArrayAdapter
class RequestClass {
private String Id;
private String BookingTime;
private String UserName;
private String Rating;
public RequestClass(String Id,String bookingTime,String userName,String rating){
this.Id=Id;
this.BookingTime=bookingTime;

this.Rating=rating;
}
public String getId(){return Id; }
public String getBookingTime(){return BookingTime; }
public String getUserName(){return UserName; }
public String getRating(){return Rating; }
}
Основна діяльність:
ArrayList<RequestClass> _requestList;
_requestList=new ArrayList<>();
try {
JSONObject jsonobject = new JSONObject(result);
JSONArray JO = jsonobject.getJSONArray("Record");
JSONObject object;
for (int i = 0; i < JO.length(); i++) {
object = (JSONObject) JO.get(i);
_requestList.add(new RequestClass( object.optString("playerID"),object.optString("booking_time"),
object.optString("username"),object.optString("rate") ));
}
RequestCustomAdapter adapter = new RequestCustomAdapter(context, R.layout.requestlayout, _requestList);
listView.setAdapter(adapter);
