预先导入数据模式：
/*** Created by lenovo on 2018/5/18.*/public class DeivceListData {private DeivceListData(){}//创建点击接口public interface ClickEvent{public abstract void onClick(Context c);}//创建数据单例的内部类public class Item{//添加需要的属性private int image;private String name;private ClickEvent click;public ClickEvent setClick(){if(this.click != null){return this.click;}return null;}public int getImage(){return this.image;}public String getName(){return this.name;}public Item (int image,String name,ClickEvent click){this.image = image;this.name = name;this.click = click;}}//创建listprivate List<Item> list = new ArrayList<Item>();//添加数据，并且返回集合public List<Item> initdata(){list.clear();list.add(new Item(R.mipmap.default_avatar, "儿子", new ClickEvent() {@Overridepublic void onClick(Context c) {Toast.makeText(c,"你点击了儿子",Toast.LENGTH_SHORT).show();}}));list.add(new Item(R.mipmap.default_avatar, "女儿", new ClickEvent() {@Overridepublic void onClick(Context c) {Toast.makeText(c,"你点击了女儿",Toast.LENGTH_SHORT).show();}}));return this.list;}//实现class的单例模式private static DeivceListData deivceListData ;public static DeivceListData I (){if(deivceListData == null){deivceListData = new DeivceListData();}return deivceListData;}
}
2.将数据导入适配器
DeivceListAdapter deivceListAdapter = new DeivceListAdapter(DeivceListData.I().initdata(),this);recyclerView.setAdapter(deivceListAdapter);
3.在适配器里实现的点击事件，回调：
@Overridepublic ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.device_list_row_layout,parent,false);final ViewHolder holder = new ViewHolder(view);/*添加选中的打勾显示*/holder.mListLayout.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//将点击的位置传出去mposition = holder.getAdapterPosition();//将点击回调出去mList.get(mposition).setClick().onClick(mContext);}});return holder;}
另一种形式，这种形式可以只需要一个position值（positon值可以从ListView的适配器里的点击事件用接口传出）就可以在任意的activity去操作remove或者clear在或者add，也可以直接修改某个item的值，但是需要注意clear否则在某些activity的listView里可能重复导入数据。
