【问题描述】:
我有以下来自服务器的 json。它是一个包含不同对象的 json 数组。我想根据键“类型”识别用户对象并将它们添加到用户哈希图中并获取用户以在我的视图中显示包含“付款”对象的信息。我正在使用 gson 和改造。 TIA
"included":[
{
"id":"1",
"type":"payments",
"attributes":{
"amount_cents":100,
"amount_currency":"INR",
"description":"Test description!!",
"created_at":"2016-03-01T11:30:53Z",
"status":"paid",
"paid_at":null,
"charged_at":null,
"formatted_amount":"Rs1.00"
},
"relationships":{
"sender":{
"data":{
"id":"2",
"type":"users"
}
},
"receiver":{
"data":{
"id":"1",
"type":"users"
}
}
}
},
{
"id":"2",
"type":"users",
"attributes":{
"first_name":"Rob",
"last_name":"Thomas"
}
},
{
"id":"1",
"type":"users",
"attributes":{
"first_name":"Matt",
"last_name":"Thomas"
}
}]
我的课是
public class ActivityFeedItem implements IFeedItem {
@SerializedName("id")
String id;
@SerializedName("type")
String type;
@SerializedName("attributes")
Attributes attributes;
protected class Attributes {
double amount_cents;
String amount_currency;
String description;
String created_at;
String status;
String paid_at;
String charged_at;
String formatted_amount;
Relationships relationships;
public double getAmount_cents() {
return amount_cents;
}
public String getAmount_currency() {
return amount_currency;
}
public String getDescription() {
return description;
}
public String getCreated_at() {
return created_at;
}
public String getStatus() {
return status;
}
public String getPaid_at() {
return paid_at;
}
public String getCharged_at() {
return charged_at;
}
public String getFormatted_amount() {
return formatted_amount;
}
public Relationships getRelationships() {
return relationships;
}
}
}
和
public class UserFeedItem implements IFeedItem {
@SerializedName("id")
String id;
@SerializedName("type")
String type;
@SerializedName("attributes")
Attributes attributes;
public class Attributes {
@SerializedName("first_name")
String first_name;
@SerializedName("last_name")
String last_name;
}
}
【问题讨论】:
-
循环遍历
included数组并将其添加到您的用户哈希图中。就像@NoChinDeluxe 做的那样,但现在使用 gson 类数组。 -
在 JSON 对象中,第一个对象的属性与第二个和第三个对象相比是不同的,在这种情况下您可以如何检索。在迭代中它会找到不同的键。
