当数据准备就绪时，从改造的警报Mainthread

我有一个改造请求，当我在onResponse中获取数据时，我在上面的代码中称为繁重工作的文本视图中插入了倍数，我从OnReponse得到结果，否则我会从数据库中得到结果，所以问题是我在OnResponse和OnFailure中有相同的代码，所以有任何方法可以将我繁重的工作放在改进之外，并等待响应只从OnResponse或OnFailure获得一个结果？当数据准备就绪时，从改造的警报Mainthread

call.enqueue(new Callback<Dashboard>() { 
        @Override 
        public void onResponse(Call<Dashboard> call, Response<Dashboard> response) { 
         realm.beginTransaction(); 
         dashboard = realm.copyToRealmOrUpdate(response.body()); 
         realm.commitTransaction(); 
         // heavy work : insert in data in multiple text views 
        } 
        @Override 
        public void onFailure(Call<Dashboard> call, Throwable t) { 
         Log.e("error ", "" + t.getMessage()); 
         dashboard = realm.where(Dashboard.class).findFirst(); 
         // heavy work : insert in data in multiple text views 
        } 
       }

试试这个.. 首先创建一个接口..Let称之为OKCallback。

public interface OKCallback { 
void onSuccess(String result); 
void onFailure(String result);

}在方法启动改造要求

然后，通过最终OKCallback okCallback这样的..

public void NetworkCall(final OKCallback okCallback){ 
........... 
call.enqueue(new Callback<Dashboard>() { 
      @Override 
      public void onResponse(Call<Dashboard> call, Response<Dashboard> response) { 
       realm.beginTransaction(); 
       dashboard = realm.copyToRealmOrUpdate(response.body()); 
       realm.commitTransaction(); 
       // heavy work : insert in data in multiple text views 
       okCallback.onSuccess(parcel); 
}

最后只需在任何类或活动（ActivityX实现OKCallback）和您应该可以在那里完成繁重的工作。您还可以使用Handler将数据包装在onSuccess方法中，如图所示。

@Override 
public void onSuccess(String result) { 
    Handler handler = new Handler(ActivityX.this.getMainLooper()); 
    //process result and 
    handler.post(new Runnable() { 
     @Override 
     public void run() { 
      //heavy work done here will run on UI thread 
     } 
    }); 
}

你可以改变它这样

//create a interface 
    public interface ConfirmationCallback { 
      void onSuccess(YourResponseClass value); 
      void onError(); 
    } 
    //call this method from your class 
    yourApiCall(new ConfirmationCallback() { 
       @Override 
       public void onSuccess(YourResponseClass value) { 
        realm.beginTransaction(); 
        dashboard = realm.copyToRealmOrUpdate(value); 
        realm.commitTransaction(); 
        // heavy work : insert in data in multiple text views 
       } 
       @Override 
       public void onError() { 
        dashboard = realm.where(Dashboard.class).findFirst(); 
        // heavy work : insert in data in multiple text views 
       } 
      }); 
     public void yourApiCall(final ConfirmationCallback confirmationCallback){ 
      call.enqueue(new Callback<Dashboard>() { 
       @Override 
       public void onResponse(Call<Dashboard> call, Response<Dashboard> response) { 
        confirmationCallback.onSuccess(response.body()); 
       } 
       @Override 
       public void onFailure(Call<Dashboard> call, Throwable t) { 
        Log.e("error ", "" + t.getMessage()); 
        confirmationCallback.onError(); 
       } 
      } 
     }
