Fetch Data Retrofit/OkHttp With Response List

问题

我从API apiServices.getPromo获取了一些数据，你可以看到URL如下，JSON如下所示：

MainActivity.java

  1. apiServices.getPromo(intentData.getStringExtra("event_id"), dataBooking.getString("total_buyer"), prefManager.getIdUser(), intentData.getStringExtra("ticket_id")).enqueue(new Callback<List<Promo>>() {
  2.     @Override
  3.     public void onResponse(@NonNull Call<List<Promo>> call, @NonNull Response<List<Promo>> response) {
  4.         if (response.isSuccessful()) {
  5.             if (!response.body().isEmpty()) {
  6.                 List<Promo> jsonData = response.body();
  7.                 Log.i("TESTER", "" + jsonData);
  8.             } else {
  9.                 Toast.makeText(PaymentActivity.this, "Maaf, belum ada promo yang tersedia.", Toast.LENGTH_SHORT).show();
  10.             }
  11.         }
  12.     }
  13. });

ApiUrl.java

  1. @FormUrlEncoded
  2. @POST("promopublic")
  3. Call<List<Promo>> getPromo(
  4.         @Field("id_event") String id_event,
  5.         @Field("total_buyer") String totalBuyer,
  6.         @Field("id_user") String id_user,
  7.         @Field("id_ticket") String id_ticket);

带有以下结构的POJO：

Promo.java

  1. public class Promo {
  2.     @SerializedName("id_promo")
  3.     private String id_promo;
  4.     @SerializedName("promo_name")
  5.     private String promo_name;
  6.     @SerializedName("promo_type")
  7.     private String promo_type;
  8.     @SerializedName("value_based")
  9.     private String value_based;
  10.     @SerializedName("quota")
  11.     private String quota;
  12.     @SerializedName("id_event")
  13.     private String id_event;
  14.     @SerializedName("description")
  15.     private String description;
  17.     public String getId_promo() {
  18.         return id_promo;
  19.     }
  21.     public void setId_promo(String id_promo) {
  22.         this.id_promo = id_promo;
  23.     }
  25.     public String getPromo_name() {
  26.         return promo_name;
  27.     }
  28. }

日志显示如下图所示，我的问题是如何提取这些数据并使用数组中的对象？谢谢。

获取数据 Retrofit/OkHttp 与响应列表

MainActivity.java

  1. apiServices.getPromo(intentData.getStringExtra(&quot;event_id&quot;),dataBooking.getString(&quot;total_buyer&quot;),prefManager.getIdUser(),intentData.getStringExtra(&quot;ticket_id&quot;)).enqueue(new Callback&lt;List&lt;Promo&gt;&gt;() {
  2.                 @Override
  3.                 public void onResponse(@NonNull Call&lt;List&lt;Promo&gt;&gt; call, @NonNull Response&lt;List&lt;Promo&gt;&gt; response) {
  4.                     if (response.isSuccessful()){
  5.                         if (!response.body().isEmpty()){
  6.                             List&lt;Promo&gt; jsonData = response.body();
  7.                             Log.i(&quot;TESTER&quot;,&quot;&quot;+jsonData);
  8.                         }else{
  9.                             Toast.makeText(PaymentActivity.this, &quot;Maaf, belum ada promo yang tersedia.&quot;, Toast.LENGTH_SHORT).show();
  10.                         }

ApiUrl.java

  1. @FormUrlEncoded
  2.     @POST(&quot;promopublic&quot;)
  3.     Call&lt;List&lt;Promo&gt;&gt; getPromo(
  4.             @Field(&quot;id_event&quot;) String id_event,
  5.             @Field(&quot;total_buyer&quot;) String totalBuyer,
  6.             @Field(&quot;id_user&quot;) String id_user,
  7.             @Field(&quot;id_ticket&quot;) String id_ticket);

with POJO that looks like this,

Promo.java

  1. public class Promo  {
  2.     @SerializedName(&quot;id_promo&quot;)
  3.     private String id_promo;
  4.     @SerializedName(&quot;promo_name&quot;)
  5.     private String promo_name;
  6.     @SerializedName(&quot;promo_type&quot;)
  7.     private String promo_type;
  8.     @SerializedName(&quot;value_based&quot;)
  9.     private String value_based;
  10.     @SerializedName(&quot;quota&quot;)
  11.     private String quota;
  12.     @SerializedName(&quot;id_event&quot;)
  13.     private String id_event;
  14.     @SerializedName(&quot;description&quot;)
  15.     private String description;
  17.     public String getId_promo() {
  18.         return id_promo;
  19.     }
  21.     public void setId_promo(String id_promo) {
  22.         this.id_promo = id_promo;
  23.     }
  25.     public String getPromo_name() {
  26.         return promo_name;
  27.     }

The Log show like the picture below, my question is how can I extract those data and use the object inside the array? Thanks.

得分: 1

  1. List<Promo> jsonData = response.body();
  2. Log.i("TESTER", "" + jsonData);
  3. String name = jsonData.get(0).getPromo_name();
  4. Log.i("TESTER", "" + name);
英文:

Nevermind, this is the trick I used

  1. List&lt;Promo&gt; jsonData = response.body();
  2. Log.i(&quot;TESTER&quot;,&quot;&quot;+jsonData);
  3. String name = jsonData.get(0).getPromo_name();
  4. Log.i(&quot;TESTER&quot;,&quot;&quot;+name);
