首先，创建InspectionLibrary对象
class InspectionLibrary
{
int id;
String desc;
String system;
int systemId;
boolean inspectionFlag;
String firebaseKey;
String systemFirebaseKey;
}
然后是内容对象（不要忘记创建InspectionList对象）。
class ResultContent
{
String customer;
String vehicle;
InspectionLibrary[] inspectionLibrary;
InspectionList[] inspectionList;
String zoneTime;
}
然后是结果对象：
class ApiResult
{
ResultContent content;
String status;
}
最后，从Api界面添加此方法（别忘了重新放置POST批注中的文本）：
@POST("Path")
Call<ApiResult> getResult();

我的理解...您正在进行改造，并希望以json解析的形式获得响应。
为此，首先必须使用http://www.jsonschema2pojo.org/内部包来创建模型类：定义应用程序根包名称。班级名称：提供您想保留的班级名称。但是，请确保该给定的类名将成为模型的根类。如您所见，您的json具有分层模型。
目标语言：Java源类型：Json批注类型：Gson检查：使用双数并包含getter和setter。
这是使用将能够创建Model类的配置。
让我们了解您的json：它将如何工作？假设我使用了包名：com测试示例类名：TestDao
之后，我下载了TestDao-source.zip
现在解压缩此内容：您将看到文件夹代码->测试->示例->文件
Content.java InspectionalLibrary.java TestDao.java
所以我希望你对此有所了解。让我解释一下：看一下您的json。
第1步：在json中，您有两件事内容和状态，即json的根键值。因此，这两件事进入TestDao.java
第2步：下一步是什么？参见...第二层次结构是具有顾客，车辆，inspectionLibrary，inspectionList，zoneTime的“内容”。所有这些键值都位于“ content”中，这就是为什么另一个模型类名称为content.java
第3步：第三个层次是“ inspectionLibrary”，其中包含id，desc，system，systemId，inspectionFlag，firebaseKey，systemFirebaseKey。所有这些键值都位于“ Inspectional Library”中，这就是为什么另一个模型类名称为“ inspectionalLibrary.java”的原因。
第4步：四个层次结构是“ inspectionList”，当前没有任何数据表示空值。因此，一旦将有数组格式的数据，然后像InspectionalLibrary一样，您将不得不制作另一个类并编写这些类的getter setter方法。
@SerializedName（“ content”）@Expose
每个模型类的每个变量都具有这些注释。这表示serializedName，它表示一旦在改造中使用了该模型类，则GSON Parser将会以“ SerializedName（“ Key_Name”）”为目标。意思是括号内的内容只不过是json的键而已，它可以帮助GSON解析您的值。
@Expose有助于使用定义的变量公开解析后的值。
我希望你理解这就是我们必须阅读json的方式。

现在让我们谈谈改造。
RestAPI.java 这基本上是用于make api的调用。
public class RestClient {
private static TestWebService gitApiInterface ;
private static String baseUrl = "https://example.com" ; // your api base url
public static TestWebService getClient() {
if (gitApiInterface == null) {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BASIC);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(logging);
httpClient.connectTimeout(30, TimeUnit.SECONDS);
Retrofit client = new Retrofit.Builder()
.baseUrl(baseUrl)
.client(httpClient.build())
.addConverterFactory(GsonConverterFactory.create())
.build();
gitApiInterface = client.create(TestWebService.class);
}
return gitApiInterface ;
}
public interface TestWebService
{
@POST("/subtypeindex/{param1}/{param2}/")
Call<TestDao> getSampleApiResponse(@Path(value = "param1") String param1,
@Path(value = "param1") String param2);
}
}
请参见接口TestWebService的内部，我编写了一个方法“ getSampleApiResponse”，该方法返回TestDao（之前我曾解释过这是模型的根类）。在@POST中，您可以修改其余的api url，但在类开始时定义的基址除外。您可以根据需要定义参数。可以使用不同形式的参数分配。供参考，请通过改造官方网站。
这是您可以从活动或片段中调用的方法。现在在这里，您需要确保从接口返回的任何内容都与Call中具有映射的类相同。这就是它将与您的界面链接并帮助您调用定义api的方式。
private void callTestApi()
{
RestClient.TestWebService service = RestClient.getClient();
Call<TestDao> callTestApi = service.getSampleApiResponse("param1", "param2");
callTestApi.enqueue(new Callback<TestDao>()
{
@Override
public void onResponse(Call<TestDao> call, Response<TestDao> response)
{
if(response.raw().code()==200)
{
if(response.body().getStatus().toString().equalsIgnoreCase("1"))
{
mUserMenuAdapter = new UserMenuViewAdapter(MainActivity.this,
response.body().getContent().getInspectionList());
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new
LinearLayoutManager(MainActivity.this));
mRecyclerView.setAdapter(mUserMenuAdapter);
}
else
{
Toast.makeText(getApplicationContext(),"Prompt Error
Msg",Toast.LENGTH_SHORT).show();
}
}
else
{
Toast.makeText(getApplicationContext(),"Prompt Error
Msg",Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call<TestDao> call, Throwable t)
{
t.printStackTrace();
}
});
}
我希望这可以帮助您了解使用翻新的api调用的基本流程以及如何在使用前读取json。
