调用startRefresh以后，当reyclerview的adapter初始数据list为空的时候，onRefresh会调用两次？

[lcodecorex]

@fjzboy 只会调用一次啊

[fjzboy]

前提是，recyclerview的adapter数据初始化为空的情况下，调用startRefresh

public class TwinklingRefreshLayoutDemo extends AppCompatActivity {

public static final String TAG = "TRL";

TwinklingRefreshLayout trl;
RecyclerView rv;
MyAdapter adapter;
private List<String> data = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_twinkling_refresh_layout_demo);

    initViews();
}

private void initViews() {

    rv = (RecyclerView) findViewById(R.id.recyclerview);

    rv.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
    adapter = new MyAdapter(this);
    adapter.setData(data);
    rv.setAdapter(adapter);

    trl = (TwinklingRefreshLayout) findViewById(R.id.twinklingrefreshlayout);
    trl.setOnRefreshListener(new RefreshListenerAdapter() {
        @Override
        public void onRefresh(TwinklingRefreshLayout refreshLayout) {
            Log.e(TAG, "on refresh");

        }

        @Override
        public void onLoadMore(TwinklingRefreshLayout refreshLayout) {
            super.onLoadMore(refreshLayout);
            Log.e(TAG, "on loadmore");
        }
    });
    trl.post(new Runnable() {
        @Override
        public void run() {
            trl.startRefresh();
        }
    });
}

class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {

    private List<String> data;
    private Context context;
    private LayoutInflater inflater;

    public MyAdapter(Context context) {
        inflater = LayoutInflater.from(context);
    }

    public void setData(List<String> data) {
        this.data = data;
        notifyDataSetChanged();
    }

    @Override
    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.list_item, parent, false);
        return new ViewHolder(view);
    }

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

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

    public class ViewHolder extends RecyclerView.ViewHolder{

        public TextView tv;

        public ViewHolder(View itemView) {
            super(itemView);
            tv = (TextView) itemView.findViewById(R.id.tv);
        }
    }
}

@fjzboy 不好意思，现在电脑出了点问题。我稍晚一些查下问题，给你答复

[fjzboy]

好的，多谢

[timshinlee]

我好像也碰到这种情况了，打日志会接收到两次数据

[lcodecorex]

疏忽了。小问题。还有其它几个小问题一起修复之后会发布一个紧急发布的版本。感谢反馈！

[lcodecorex]

@fjzboy @timshinlee 问题已解决

[fjzboy]
