android activity调用Adapter方法刷新列表UI，RecyclerView.Adapter

在adapter中创建被调用方法cleckAll

public class JYfkleixinAdapter extends RecyclerView.Adapter<JYfkleixinAdapter.ViewHolder> {private Context context;private OnItemClickListener mOnItemClickListener;private List<JyfkEntity> entityList;public JYfkleixinAdapter(Context context, List<JyfkEntity> entities) {this.context = context;this.entityList = entities;}@Overridepublic JYfkleixinAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_jyfk, null);JYfkleixinAdapter.ViewHolder holder = new JYfkleixinAdapter.ViewHolder(view);return holder;}@Overridepublic void onBindViewHolder(final JYfkleixinAdapter.ViewHolder holder, int position) {JyfkEntity entity = entityList.get(position);//        ImageManager.loadBitmap(context, entity.getBimage(), R.mipmap.itemx_03, holder.item_intnb_image);try{holder.jyfkte.setText(entity.getName());//网吧名称if (entity.isIfselect()){holder.jyfkimage.setSelected(true);}else {holder.jyfkimage.setSelected(false);}}catch(Exception e){e.printStackTrace();}//判断是否设置了监听器if (mOnItemClickListener != null) {//为ItemView设置监听器-holder.itemView.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {int position = holder.getLayoutPosition(); // 1mOnItemClickListener.onItemClick(holder.itemView, position); // 2}});}}@Overridepublic int getItemCount() {return entityList.size();}public class ViewHolder extends RecyclerView.ViewHolder {@BindView(R.id.jyfkte)TextView jyfkte;@BindView(R.id.jyfkimage)ImageView jyfkimage;public ViewHolder(View itemView) {super(itemView);ButterKnife.bind(this, itemView);}}public interface OnItemClickListener {void onItemClick(View view, int position);}public void setOnItemClickListener(OnItemClickListener onItemClickListener) {this.mOnItemClickListener = onItemClickListener;}//  删除 打勾 全选public void cleckAll(int  is_checked) { //全选 删除多少那里要删除全部for (int a = 0;a<entityList.size();a++){if (is_checked==a){entityList.get(a).setIfselect(true);}else {entityList.get(a).setIfselect(false);}}notifyDataSetChanged();}}

在activity中调用刷新UI

public void initrecyclerview(){barAdapter = new JYfkleixinAdapter(JYfkActivity.this,barEntityList);barAdapter.setOnItemClickListener(new JYfkleixinAdapter.OnItemClickListener() {@Overridepublic void onItemClick(View view, int position) {barAdapter.cleckAll(position);jylx = barEntityList.get(position).getName();}});jyfkrecyclerview.setLayoutManager(new LinearLayoutManager(JYfkActivity.this));jyfkrecyclerview.setAdapter(barAdapter);jyfkrecyclerview.setNestedScrollingEnabled(false);//禁止滑动jyfkrecyclerview.setFocusable(false);//导航栏切换不再focuse
}

ShebeilistAdapter adapter;

adapter = new ShebeilistAdapter(this);

adapter.setNewData(list);

helper.setText(R.id.tx_username, item.getNickname()).setText(R.id.tx_time, NewsTimeChangeUtil.getTimeFormatText(new Date(item.getCtime() * 1000))).setText(R.id.tx_content, item.getContent()).setText(R.id.tx_discuss_num, item.getComment() + "").setText(R.id.cb_zan_num, item.getLikes() + "").addOnClickListener(R.id.cb_collect)
