在打开键盘设备之前,回收器不显示任何数据

我有recyclerview并从网络服务获取信息。

public void Load() {
    counter = 0;
    adapterComment = new AdapterComment(G.context, comments);
    mRecyclerView.setAdapter(adapterComment);

    VolleyRequestHelper volleyRequestHelper = new VolleyRequestHelper(Request.Method.POST, G.URL_ADDRESS_MUSIC + "get_song_comment/page/" + counter, map, new Response.Listener<String>() {
      @Override
      public void onResponse(String response) {
      //get data
          }
          adapterComment.notifyDataSetChanged();

        } catch (JSONException e) {
          e.printStackTrace();
        }
      }
    }, new Response.ErrorListener() {
      @Override
      public void onErrorResponse(VolleyError error) {
      }
    });
Volley.newRequestQueue(G.context).add(volleyRequestHelper);

} 每次回收者显示20项时我都会使用无限滚动,如果数据较大则没有问题如果数据较小20回收者在打开键盘设备之前不显示数据(我在图层中有edittext)。

public void LoadMore() {
    counter = (counter + 1);
    adapterComment = new AdapterComment(G.context, comments);
    mRecyclerView.setAdapter(adapterComment);
    VolleyRequestHelper volleyRequestHelper = new VolleyRequestHelper(Request.Method.POST, G.URL_ADDRESS_MUSIC + "get_song_comment/page/" + counter, map, new Response.Listener<String>() {
      @Override
      public void onResponse(String response) {
       //get data
          }
          adapterComment.notifyDataSetChanged();

        } catch (JSONException e) {
          e.printStackTrace();
        }
      }
    }, new Response.ErrorListener() {
      @Override
      public void onErrorResponse(VolleyError error) {

      }
    });
    Volley.newRequestQueue(G.context).add(volleyRequestHelper);
  }

并在onCreatView中:

Load();
    mRecyclerView.addOnScrollListener(new EndlessRecyclerOnScrollListener(linearLayoutManager) {
      @Override
      public void onLoadMore(int current_page) {
        int lastFirstVisiblePosition = ((LinearLayoutManager) mRecyclerView.getLayoutManager()).findFirstVisibleItemPosition();
        ((LinearLayoutManager) mRecyclerView.getLayoutManager()).scrollToPosition(lastFirstVisiblePosition);
        LoadMore();
      }
    });
