我试图填充observersIDs ArrayList，然后将其作为参数放入我的TicketModel对象的设置器ticket.setObserverIDs(observersIDs)中。
在调用设置器之前，我正在按照DisplayArrayList(observersIDs)的顺序显示ArrayList内容。幸运的是，该列表包含了我想要的值。
但是，当我在填充ListView（在循环外部）并显示其内容后调用吸气剂时，ArrayList为空。我很确定这是因为我要在每个TicketModels.add(ticket);之后清除我的ArrayList（我确实需要该指令），但这并没有意义，因为我没有显示该ArrayList，而是打电话给我已填充的TicketModek对象的getter。
这是我的课程：

Statut = statut;
}
public String getTitreTicket() {
return titreTicket;
}
public String getSlaTicket() {
return slaTicket;
}
public String getDateTicket() {
return DateTicket;
}
public String getUrgenceTicket() {
return UrgenceTicket;
}
public void setUrgenceTicket(String urgenceTicket) {
UrgenceTicket = urgenceTicket;
}
public void setTempsRestantTicket(String tempsRestantTicket) { TempsRestantTicket = tempsRestantTicket; }
public String getTempsRestantTicket() {
return TempsRestantTicket;
}
public boolean isTicketEnRetard() {
return ticketEnRetard;
}
public void setTicketEnRetard(boolean ticketEnRetard) {
this.ticketEnRetard = ticketEnRetard;
}
public String getIdTicket() { return idTicket; }
public String getStatut() { return Statut; }
public String getTempsResolution() {
return TempsResolution;
}
public void setTempsResolution(String tempsResolution) {
TempsResolution = tempsResolution;
}
public String getTempsRetard() {
return TempsRetard;
}
public void setTempsRetard(String tempsRetard) {
TempsRetard = tempsRetard;
}
public void setDescription(String description) {
this.description = description;
}
public String getDescription() {
return description;
}
public void setDemandeurID(String demandeurID) {
this.demandeurID = demandeurID;
}
public String getDemandeurID() {
return demandeurID;
}
public void setObserverIDs(ArrayList<String> observerIDs) {
this.observerIDsss = observerIDs;
}
public ArrayList<String> getObserverIDs() {
return observerIDsss;
}
}
有人可以向我解释为什么在调用吸气剂时我没有得到正确的值吗？
