Question

我正在尝试使用泛型来调用API，但不会显示它们，也无法检索它们。但是，如果我在MainActivity类中完成所有“脏”工作，它可以正常工作吗？我确实在它破裂之前就收到了一个奇怪的错误。

MainActivity.java

listView = (ListView) findViewById(R.id.pagination_list);

    Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl("https://api.github.com/")
            .addConverterFactory(GsonConverterFactory.create());

    Retrofit retrofit = builder.build();

    GitHubClient c = ServiceGenerator.createService(GitHubClient.class);

    GitHubClient client = retrofit.create(GitHubClient.class);
     //Call<List<GitHubRepo>> call = client.reposForUser("fs-opensource");
    // Call<List<GitHubRepo>> call = client.reposForUser("Ricardo96MC");
    //Call<List<GitHubRepo>> call = c.reposForUser("Ricardo96MC");
   Call<List<GitHubRepo>> call = c.reposForUser("fs-opensource");


    call.enqueue(new Callback<List<GitHubRepo>>() {
        @Override
        public void onResponse(Call<List<GitHubRepo>> call, Response<List<GitHubRepo>> response) {
             List<GitHubRepo> repos = response.body();

            Log.e("Repos found"," Should be displaying on device");
            listView.setAdapter(new GitHubRepoAdapter(MainActivity.this, repos));
        }

        @Override
        public void onFailure(Call<List<GitHubRepo>> call, Throwable t) {
            Log.e("onFailure", "WHYYYYYYY");
            Toast.makeText(MainActivity.this, "error: ", Toast.LENGTH_LONG).show();
        }
    });
}

使用GitHub客户端取得了成功，但...... ServiceGenerator.java

 private static final String BASE_URL = "https://api/github.com/";

//Make static so theres one instance for entire app
private static Retrofit.Builder builder =  new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create());

//One instance for entire app
public static Retrofit retrofit = builder.build();

//Uses generics to make API call dynamic
public static<T>T createService(Class<T> serviceClass){

    Log.e("createService() : "," service created?");
    return retrofit.create(serviceClass);
}

导致空白UI和以下日志..

使用泛型调用API进行改造，调用结果onFailure（）
