全选及反选

  public void  getcheck(boolean a){
    getGetcheck(a);
    notifyDataSetChanged();
}


public void getGetcheck(boolean a) {
    map.clear();
    for(int i=0;i<list.size();i++){

有参构造中
getGetcheck(false);

  //设置全不选及全选
String s = list.get(i).getCommodityId() + "";
viewholder.check.setChecked(map.get(s));




 //在点击事件中设置反选功能
viewholder.check.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        String s = list.get(i).getCommodityId() + "";
        map.put(s,  viewholder.check.isChecked());
        boolean flag=true;

         }
       if (flag){
           bool.getdate(flag);

activity中
//设置全选及全不选
check.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (check.isChecked()){
            shoppAdapter.getcheck(true);
        }else

            shoppAdapter.getcheck(false);
        }
    }
});


//设置反选
shoppAdapter.setBool(new ShoppAdapter.Bool() {
    @Override
    public void getdate(boolean flag) {
        check.setChecked(flag);
    }
