android notifyItemRangeInserted禁用自动滚动 [英] android notifyItemRangeInserted disable autoscroll

问题描述

我正在使用RecyclerView作为数据列表的基础. 我已经实现了基于ArraList的自定义RecyclerView.Adapter.从互联网上获取数据时，我正在运行的代码是:

I'm using RecyclerView as the base for my data list. i've implemented custom RecyclerView.Adapter which is based on ArraList. on fetching data from the internet the code that i'm running is:

public void addItems(List<Item> items){

    final int size = data.size();
    data.addAll(items);
    notifyItemRangeInserted(size, items.size());
}

问题在于，运行此代码后，我将自动滚动到列表的底部(现在可以看到最后一个元素)

Problem is that for after running this code i'm getting an autoscroll to the bottom of the list (last element is now visible)

是否可以禁用此功能?找不到任何类似的问题.

Is there a way to disable this? couldn't find any similar questions.

相关信息:我的适配器具有2个viewHolders-对于位置0，它具有一个视图(viewType为0) 对于列表的其余部分，其视图类型为viewType 1

relevant information: my adapter have 2 viewHolders - for position 0 it has a view (with viewType 0) and for the rest of list it has view with viewType 1

感谢您的帮助！

推荐答案

问题就在您的positionStart中.应该是:

Problem is in your positionStart. Should be:

public void addItems(List<QuestItem> items){    
    final int positionStart = data.size() + 1;
    data.addAll(items);
    notifyItemRangeInserted(positionStart, items.size());
}
