public class MyRecyclerViewAdapter extends RecyclerView.Adapter implements View.OnClickListener { private Context context; private List list; private List booleanlist=new ArrayList<>(); public MyRecyclerViewAdapter(Context context) { this.context=context; list=new ArrayList<>(); }public MyRecyclerViewAdapter(Context context,List list) { this.context=context; this.list=list; for (int i = 0; i < list.size(); i++) { //设置默认的显示 booleanlist.add(false); } }public void addData(List strings){list.addAll(strings); for (int i = 0; i < strings.size(); i++) { booleanlist.add(false); } notifyDataSetChanged(); }//更改集合内部存储的状态 public void initCheck(boolean flag) {for (int i = 0; i < list.size(); i++) { //更改指定位置的数据 booleanlist.set(i,flag); } }@Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { MyViewHolder holder = new MyViewHolder(LayoutInflater.from( context).inflate(R.layout.list_item1, parent, false)); return holder; }@Override public void onBindViewHolder(final MyViewHolder holder, final int position) { holder.tv.setText(list.get(position)); holder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {@Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { //用集合保存当前的状态 booleanlist.set(position,isChecked); } }); holder.cb.setChecked(booleanlist.get(position)); }@Override public int getItemCount() { return list.size(); }//清空所有数据 public void deleteAllData() {list.clear(); booleanlist.clear(); notifyDataSetChanged(); }//删除选中的数据 public void deletingData() {int y=0; for (int i = 0; i < list.size(); i++) { if(booleanlist.get(i)!=null && booleanlist.get(i) ) { list.remove(i); booleanlist.remove(i); y++; i--; } } notifyDataSetChanged(); if(y==0){ Toast.makeText(context, "没有选中的要删除的数据", Toast.LENGTH_SHORT).show(); } }public void selectAll(){ initCheck(true); notifyDataSetChanged(); } public void unSelectAll(){ initCheck(false); notifyDataSetChanged(); }/** * ViewHolder的类，用于缓存控件 */ class MyViewHolder extends RecyclerView.ViewHolder {CheckBox cb; TextView tv; public MyViewHolder(View view) { super(view); cb = (CheckBox) view.findViewById(R.id.list_item1_cb); tv = (TextView) view.findViewById(R.id.list_item1_tv); }} }
