SearchView搜索

Question

我有一个RecylerView，它具有SearchView小部件以及包含复选框和播放器名称的项目列表。当我滚动项目并选择项目复选框时，没有问题。但是，当我按名称搜索项目然后选择它们时，就会出现问题，当我尝试搜索另一个项目时，先前的项目会被取消选中。

当我键入BAT并显示带有蝙蝠的玩家列表时，我选择了2位玩家

然后我从搜索视图中删除了BAT，您可以看到两个选中的球员都被取消了选择

您必须为此使用循环。

    if (players.get(position).isselected) {
        chk.setChecked(true);

        for(PlayersPool item: searchdata){
            if(players.get(position).getName().equals(item.getName())){
                item.setIsselected(true);
            }
        }

    } else {
        chk.setChecked(false);
    }
