我正与Android的新RecyclerView，但我不能让我的自定义适配器刷新每当我称之为的通知的方法之一。

I'm working with Android's new RecyclerView but I can't get my custom adapter to refresh whenever I call one of the "notify" methods.

我已经打过电话notifyDataSetChanged，notifyItemRangeInserted和notifyItemInserted和他们都不工作。

I've tried calling notifyDataSetChanged, notifyItemRangeInserted and notifyItemInserted and none of them seem to work.

这里的code我的自定义适配器。我基本上是试图刷新字符串列表：

Here's the code for my custom adapter. I'm basically trying to refresh a list of Strings:

package com.mycompany.myapp.adapters;

import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.mycompany.myapp.R;

import java.util.List;

public class FeedAdapter extends RecyclerView.Adapter<FeedAdapter.ViewHolder> {

    private List<String> mDataset;

    public FeedAdapter(List<String> dataset) {
        super();
        mDataset = dataset;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int i) {
        LinearLayout v = (LinearLayout) LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_item_feed, parent, false);
        v.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT));
    return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.setText(mDataset.get(position));
    }

    @Override
    public int getItemCount() {
        return mDataset.size();
    }

    public void setDataset(List<Status> dataset) {
        mDataset = dataset;
        // This isn't working
        notifyItemRangeInserted(0, mDataset.size());
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        private TextView mFeedText;

        public ViewHolder(View v) {
            super(v);
            mFeedText = (TextView) v.findViewById(R.id.feed_text);
        }

        private void setText(String text) {
            mFeedText.setText(text);
        }
    }
}

任何人有这个问题？

Anyone else having this issue?

谢谢！

推荐答案

我的问题是，我没有通知主线程上的变化，所以变化是不可见的时候了。这是同样的问题，指出here.

My issue was that I was not notifying the change on the main thread, therefore the change was not visible right away. It is the same issue pointed out here.
