Question

我需要通过改造来实现简单的例子。我用下一个

gradle dependensy：

public interface TestService {
        @GET("test")
        Test getUser();
    }

接口：

button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl("http://localhost:8080")
                        .addConverterFactory(GsonConverterFactory.create())
                        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                        .build();

                TestService service = retrofit.create(TestService.class);
                Test test = service.getUser();
                Log.d("button_click", "test: "+ test);
            }
        });

主要活动中的

java.lang.IllegalArgumentException: Could not locate call adapter for class mydomain.nfpclient.models.Test.
  Tried:
   * retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory
   * retrofit2.ExecutorCallAdapterFactory

错误

.getElementsByTagName()

您必须更改界面：

public interface TestService {
    @GET("test")
    Call<Test> getUser(); //Call<Test> instead of just Test
}

然后，像这样使用它：

<强>同步

Response<Test> response = service.getUser().execute();

<强>异步

service.getUser().enqueue(new Callback<Test>() {
    @Override
    public void onResponse(Response<Test> response) {
        //handle successful response
    }

    @Override
    public void onFailure(Throwable t) {
        //handle error
    }
});

您可以通过致电Test从Response<Test>获取response.body()。

如果您使用的是RxJava集成，请使用Observable代替Call：

public interface TestService {
    @GET("test")
    Observable<Test> getUser();
}

和

service.getUser().subscribe(
    user -> ,//do something with your user,
    error -> //something wrong happened
);

带有retrofit2的java.lang.IllegalArgumentException
