滚动时，两个复选框处于recyclerview更改状态 [英] Two checkbox in recyclerview changing state when scrolling
本文介绍了滚动时，两个复选框处于recyclerview更改状态的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
编辑
通过删除两行来解决问题
holder.checkbox.setChecked（mListenerList.get（position）.isSelected（））;
holder.checkbox.setChecked（mListenerList.get（position）.isSelected2（））;
并通过添加
@Override
public long getItemId（int position）{
返回位置；
}
@Override
public int getItemViewType（int position）{
返回位置；
}
我不为将来的开发人员编辑原始代码。
编辑之前的主要问题从这里开始
我正在研究幻想板球应用程序，我从11名球员的列表中选择队长和副队长。
我正在使用一个复选框来选择队长和副队长。
复选框的选择与我的代码配合正常，但是问题是当我选择第一名玩家作为队长（C），第二名玩家选择为副队长（VC），然后滚动列表时，复选框的状态正在改变
那么有什么正确的方法去做那件事吗？
我尝试了很多方法来解决这个问题单个复选框，但在我的情况下，只有两个复选框。
请参阅底部的屏幕截图以清楚查看。

选择C和VC
从上到下滚动后并自下而上
请忽略广播组。我的代码与复选框配合正常，只会在滚动时产生问题。
解决方案
对于 复选框 ，则需要使用 checkbox.OnCheckedChangeListener（） 而不是 checkbox.setOnClickListener（）
执行以下步骤
在您的 BeanDBTeam 类中添加一个新的布尔变量
public class BeanDBTeam
{
boolean isChecked;
public boolean getisChecked（）{
return isChecked;
}
public void setIsChecked（boolean flag）{
isChecked = flag;
}
}
现在在您的内心 onBindViewHolder（） 添加以下代码
@Override
public void onBindViewHolder（@NonNull ViewHolder viewHolder，int position）{
BeanDBTeam bean = mListenerList.get（position）.getisChecked（）
//在此处检查基于标志$的标志和复选框的状态b $ bholder.checkbox2.setChecked（bean.getisChecked（））;
holder.checkbox2.setOnCheckedChangeListener（new CompoundButton.OnCheckedChangeListener（）{
@Override
public void onCheckedChanged（CompoundButton buttonView，boolean isChecked）{
//设置标志用户选中或取消选中复选框
bean.setIsChecked（isChecked）;
notifyDataChanged（）;
}
}时列表中复选框状态的值；
}
Edit
Solved issue by removing two lines
holder.checkbox.setChecked(mListenerList.get(position).isSelected());
holder.checkbox.setChecked(mListenerList.get(position).isSelected2());
And By Adding
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getItemViewType(int position) {
return position;
}
I am not editing my original code for future developers.
Main Question before Edit Start from Here
I am working on fantasy cricket app where I am selecting the captain and vice captain from a list of 11 player.
I am using a checkbox for selecting the captain and vice captain.
The selection of checkbox is working fine with my code, but the issue is when I select 1st player as a captain(C) and 2nd player as Vice-Captain(VC) and then scroll the list the checkbox state is changing and showing other player selected.
So is there any right way to do that thing?
I have tried many way they are working when there is single checkbox but in my case there is two and only one can be select from the list.
Please refer to the attached screenshots on the bottom for clarity.

Selecting C and VC
After scrolling top to bottom and bottom to top
Please ignore Radio group. My code is working fine with checkbox, it's only creating issues when scrolling.
解决方案
For checkbox you need to use checkbox.OnCheckedChangeListener() instead of checkbox.setOnClickListener()
Follow this steps
add a new Boolean variable in your BeanDBTeam class
public class BeanDBTeam
{
boolean isChecked;
public boolean getisChecked() {
return isChecked;
}
public void setIsChecked(boolean flag) {
isChecked= flag;
}
}
Now inside you onBindViewHolder() add below code
@Override
public void onBindViewHolder(@NonNull ViewHolder viewHolder, int position) {
BeanDBTeam bean = mListenerList.get(position).getisChecked()
// check here the flag and status of checkbox based on flag
holder.checkbox2.setChecked(bean.getisChecked());
holder.checkbox2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
// set flag of checkbox status in your list when user check or uncheck the checkbox
bean.setIsChecked(isChecked);
notifyDataChanged();
}
});
}
