        RefreshLayout refreshLayout =view.findViewById(R.id.refreshLayout);//绑定那个刷新的布局
        refreshLayout.setOnRefreshListener(this::onRefresh);//设置下拉监听，当下拉的时候调用函数
        refreshLayout.setOnLoadMoreListener(this::onLoadMore);//设置上拉监听，当上拉时候调用函数

                        .start();
            }
        });


    }

    private void onRefresh(@NonNull RefreshLayout refreshLayout) {
        mPage = 1;
        OkHttp.create().getHotPhotoList(mPage).enqueue((call, httpRes)->{
            if (httpRes.isSuccessful()){
                List data=httpRes.dataFromList(DiscoverAlbum.class);
                discoverAlbumAdpter.addAll(data);
                for (DiscoverAlbum datum : data) {

    }

    private void onLoadMore(@NonNull RefreshLayout refreshlayout) {
        mPage++;
        OkHttp.create().getHotPhotoList(mPage).enqueue((call, httpRes)->{
            if (httpRes.isSuccessful()){
                List data=httpRes.dataFromList(DiscoverAlbum.class);
                if (data.size()==0) {

                }else {
                    for (DiscoverAlbum datum : data) {
                        mThumbViewInfoList.add(new UserViewInfo(datum.getUinfo().getAvatar()));
                    }

                    discoverAlbumAdpter.addAll(data);
                }

            }
        });
    }

    
    private void computeBoundsBackward(int firstCompletelyVisiblePos) {
        for (int i = firstCompletelyVisiblePos; i < mThumbViewInfoList.size(); i++) {
            View itemView = mGrid.getChildAt(i - firstCompletelyVisiblePos);
            Rect bounds = new Rect();
            if (itemView != null) {
//                //需要显示过度控件
//                ImageView thumbView = (ImageView) itemView.findViewById(R.id.iv_al);
//                //拿到在控件屏幕可见中控件显示为矩形Rect信息
//                thumbView.getGlobalVisibleRect(bounds);
            }
            mThumbViewInfoList.get(i).setBounds(bounds);
        }
    }
}

下面这个就是设置监听了

       //设置监听,点击item查看图片
        mGrid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView adapterView, View view, int i, long l) {
//                DiscoverAlbum item=discoverAlbumAdpter.getItem(i);
//                mPhotoId =item.getId();
//                Log.v("mVideoId", String.valueOf(mPhotoId));
                GPreviewBuilder.from(AlbumFragment.this)
                        .setData(mThumbViewInfoList)
                        .setCurrentIndex(i)
                        .setType(GPreviewBuilder.IndicatorType.Number)
                        .start();
            }
        });
