我正在使用Android的新RecyclerView,但是当我调用任何一个“notify”方法时,我的自定义适配器无法刷新。
我尝试过调用notifyDataSetChanged、notifyItemRangeInserted和notifyItemInserted,但似乎都不起作用。
以下是我自定义适配器的代码。我基本上正在尝试刷新一组字符串列表:
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);
}
}
}
还有其他人遇到这个问题吗?
谢谢!
