private interface ResourcesApi {
        @POST("/synchronize")
        void getResources(@Body Map<String, Map<String, Object>> map,
                          Callback<DataModel> callback);
    }

与调用代码:

mApi.getResources(data, this);

该类实现了Callback,因此定义了成功/失败.

@Override
public void onResume() {
 super.onResume();
 recyclerView.post(new Runnable() {
  @Override
  public void run() {
    ((LinearLayoutManager) recyclerView.getLayoutManager()).scrollToPositionWithOffset(position, viewTopDistance);
  }
 });
}

当用户单击启动另一个活动的视图时，位置和 viewTopDistance 会正确保存和保留。返回回收器视图后，大约 2/3 的时间列表看起来正确，另外 1/3 的时间它仅在顶部显示前 4 或 5 次（scrollToPositionWithOffset 不起作用）

关于为什么有时会失败的任何想法？
