改版删除Android

Question

我真的是第一次更新，我正在努力弄清楚如何删除

我要说的是：

interface DeleteNote {
        @DELETE("/staff/users/note")
        Response deleteResponse(
            @Query("note_id") String note_id
        );
    }

这里是我使用它的地方

RestAdapter restAdapter = new RestAdapter.Builder()
                                                .setEndpoint(Utils.getApiBaseUrl())
                                                .build();

 // Create an instance of our GitHub API interface.
    DeleteNote dn = restAdapter.create(DeleteNote.class);
    Response response = dn.deleteResponse(n.note_id);

这就是我所犯的错误：

编辑:我没有包括在更新页面上提到的okhttp --我会尝试一下，然后再回来。

要么使用Retrofit CallBack，要么在AsyncTask中包装您的方法。请检查Synchronous Vs. Asynchronous Vs. Observable

来自他们的网站的会话。

回叫的代码应该是这样的，

interface DeleteNote {
    @DELETE("/staff/users/note") 
    Response deleteResponse(
        @Query("note_id") String note_id, 
        Callback<YourObjectHere> myCallBack
    );
  }

或者，如果您根本不需要CallBack，只需将现有代码包装在AsyncTask的doInBackground方法中并执行任务即可。

会是这样的。

  public class MyTask extends AsyncTask<Void, Void, Response> {
    @Override protected String doInBackground(Void... params) {
      RestAdapter restAdapter = new RestAdapter.Builder()
                                    .setEndpoint(Utils.getApiBaseUrl()) 
                                    .build(); 

   // Create an instance of our GitHub API interface. 
      DeleteNote dn = restAdapter.create(DeleteNote.class);
      Response response = dn.deleteResponse(n.note_id);  
      return response  
    }

    @Override protected void onPostExecute(Response s) {
      super.onPostExecute(s);
    }
  }

  // Execute the task
  new MyTask().execute();
