BaseRecycleViewAdapter 、BaseQuickAdapter、BaseAdapter 的用法区别
BaseRecycleViewAdapter 和BaseQuickAdapter的用法类似，只是quickAdapter可以设置当列表下拉到底部的时候刷新获取到更多的数据，在代码中设置adapter的开启如下方法即可：adapter.openLoadAnimation();
adapter.setOnLoadMoreListener(CloudPhotosActivity.this);、
adapter.openLoadMore(pageSize, true);
而baseRecycleViewAdapter是没有如此方法实现这样的，只能手动获取其它页的数据然后再添加到之前数据列表的后面。这两种adapter在自定义撰写代码的时候，它们的代码逻辑内涵是一模一样的，仔细对照代码即可领会。
BaseAdapter 的最简单容易的Adapter，五个重要点掌握：
1、 public int getCount() {
return mediaInfoList.size();
}
2、public Object getItem(int position) {
return mediaInfoList.get(position);
}
3、public CloudPhotosGridViewAdapter(Context c, List<CloudPhotosMediaInfo> mediaInfoList) {
this.context = c;
this.mediaInfoList = mediaInfoList;
stringList = new ArrayList<>();
}
4、/**
* 存放列表项控件句柄
*/
private class ViewHolder {
ImageView iv_check;
TextView tv_duration;
ImageView iv_content;
}
5、 public View getView(int position, View convertView, ViewGroup parent) {
viewHolder = null;
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(
R.layout.cloudphotos_gridview_item, parent, false);
...
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
.....
return convertView;
}
