我想将元素添加到Android的回收者视图显示的项目列表中。
到目前为止,在我的代码中,当列表接近结尾时,我获取了更多项目,并将新项目列表附加到显示的当前列表中。然后,我调用notifyDataSetChanged(),但出现以下错误:
java.lang.IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling android.support.v7.widget.RecyclerView...
当回收者停留在当前显示的项目上时,我如何更新列表以显示?
这是我的代码:
private class StatusRecyclerAdapter extends RecyclerView.Adapter<StatusRecyclerHolder> { private List<Status> statues; private int size; private final int LOAD_POSITION = 3; public StatusRecyclerAdapter() { statues = feed.getStatuses(); } @NonNull @Override public StatusRecyclerHolder onCreateViewHolder(ViewGroup viewGroup, int i) { LayoutInflater layoutInflater = LayoutInflater.from(getActivity()); return new StatusRecyclerHolder(layoutInflater, viewGroup); } @Override public void onBindViewHolder(@NonNull StatusRecyclerHolder statusRecyclerHolder, int i) { statusRecyclerHolder.bind(statues.get(i)); if(size - i == LOAD_POSITION){ getContentNextPage(); } } @Override public int getItemCount() { size = 0; if(statues == null){ Log.i(TAG, "List of status null" ); } else{ size = statues.size(); } return size; } private void getContentNextPage(){ this.statues = Feed.getNextPage(); } notifyDataSetChanged(); } }
谢谢!
