我想开发一个网站的Android应用程序！在这个网站上，任何页面显示10个帖子，其他帖子转到页面。我可以只显示10个帖子（第1页），并在向下滚动时显示 ，在以下页面上显示更多帖子将显示10个条目 。
对于展示帖子，我使用RecyclerView组件。
Json（来自网站）：

当向下滚动时，如何在10个帖子下方显示其他页面？ 注意：我是业余开发者，请不要给我负面评价。我真的需要你的教程和指南。谢谢所有＆lt; 3

使用RecyclerView尝试这样的事情：
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
.
.
.
private boolean loading = true;
int pastVisiblesItems, visibleItemCount, totalItemCount;
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener()
{
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy)
{
if(dy > 0){
visibleItemCount = layoutManager.getChildCount();
totalItemCount = layoutManager.getItemCount();
pastVisiblesItems = layoutManager.findFirstVisibleItemPosition();
if (loading)
{
if ( (visibleItemCount + pastVisiblesItems) >= totalItemCount)
{
loading = false;
//load new data
}
}
}
}
});
